RE: [PHP-DB] write to word..
Better still,
Take a look at RTF as a file format. Its readable in Word, looks like a Word
doc and can be saved with a '.doc' extension and you can store placeholders
that php can use to 'mail-merge' with.
Works for me.

Hi
I did it like this

//then output it
header (Content-type: application/msword);
header (Content-Disposition: attachment;

include('letter.htm');
print('done it')

I wrote the letter to file and then included it, but you can probably just
print HTML as you would normally. Word will open HTML files and
maintain the

hi,
I'm just wondering if it is possible to write to a word document or any
other file type that would allow for easy editing(besides txt) with out
having to copy and past everything in? I'm looking to have a template
perhaps in word and have the code insert variables from the database.
If it is possible, could some one point me in the right direction. Like
where to look in the manual.
Thanks,

[PHP-DB] odbc going nuts
Hi all, Just finishing off a site using odbc and Access and it's thrown up a problem that wasn't there yesterday. I have a simple login with a username and password. If either are blank, the user gets bumped to the login page. otherwise the user table is searched for the username and password. my code looks like: $strSQL = select * from user where (Username='$username' and Paswd='$paswd'); I have an error script that kicks in if the query fails, and prints the query to screen. I've pasted the query straight into Access' SQL query window and it worked fine. I just can't see anything wrong with the code, or anything else. Any suggestions (apart from dropping Access in favour of another db - client choice) Cheers George in Oxford -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP-DB] ODBC and error management
Nico, I'm using MyODBC to query MySQL (because my client want's it to work in Access, and I don't and this leaves the least amount of code to change). I don't get an error message if the result is empty (no records). I do a while loop and add to a counter and if the counter 1 then its empty otherwise I display the results. I do get the errors though when the query is 'bad' - contains errors. I'm running mine on both WinNT and Win2K with identical results. Hope this helps.

Can I raise a point of principle here.
My databases never have records deleted - instead they are marked as being
deleted in a status field. That way, they are always there for reference.
Unless you are running a system that needs the space or has extremely high
turnover of deleted records, this makes sesne.

Easy one.. :)
Make sure your checkboxes have the rowID as their value, then you can
simply
do this:
$query = DELETE FROM table WHERE rowID IN ( .
implode(',',$_POST['checkboxes']) . );
and run that query.
You'll end up with something that looks like this:
DELETE FROM table WHERE rowID IN (1,2,3,4,5)
where the numbers will come from only the checkboxes that you selected.

[PHP-DB] Dumping MySQL rows into a 2D array

while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

$dbRow['ev_sd']= $row[start_day];
$dbRow['ev_ed']= $row[end_day];
}
}
In my sample database, I have two records which are both found with the
query (tested in MySQLFront) but the array ends up with 3 rows each with the
last record in it.

first leave out the loop with for ($i...).
then use the loop with while and make sure that you create

so add those brackets: []:

[PHP-DB] variation on(Speed Up Code?)
Hi all, One of the pages in my site takes up to 10 seconds to display (depending on number of records (30 records takes 10 secs). The cause of the problem is the amount of information I am displaying for each record. I do multiple queries for each record to find out different things such as its position in the workflow, its price, etc. None of these are stored in the db, but are calculated on the fly depending on the data held. Apart from storing the result in the db can anyone point me in the direction of some efficient handling routines? Code is available if anyone wants bloat-mail!

Doug, Sorry for leaving this so long but I've been tied up in business meetings. It may be that my query is restricting the data retrieval but I cannot see how. If I look at the data I am playing with, I have 3 tables and I want to show transactions from a certain course. I also want to show related information from the bib_extract table and the scanrates (prices) table. I've checked the data in these tables and nothing is odd.

$link = mysql_connect ('localhost', 'root', '*') or die (Could
not
select db);
mysql_select_db ('Heronsql') or die (Could not connect);
?
I have also tried it with the following:
?php
$link = mysql_connect ('localhost', 'root', '*');
echo mysql_errno().: .mysql_error().BR;
mysql_select_db ('Heronsql');
echo mysql_errno().: .mysql_error().BR;
?
Te results for this were:
0:0
0:0
I have reinstalled my Mandrake (MySQL/PHP4.0.6/Apache) and I am about
to
retest so I'll report back soon.

Subject: Re: [PHP-DB] Problem connecting to db on Linux
I've been working with PHP/MySQL on Win NT and Win 2000 for a few
weeks.
I've now set up a Linux machine (Mandrake 8.1 on Dell laptop) and
have
moved
my files across.
I use an include file which logs on to the MySQL server and then
connects
to
the database. It performs the login ok but not the select db part.
I tried creating a db using a php script and then selecting it and
got
the
same problem.
I'm new on Linux so it might be something in the configuration
which
needs
working on.
Any suggestions?
Well, if you had posted some code, someone might have seen the
error...
:(
Anyway, here is how i do it:
if($db = mysql_pconnect($dbhost, $dbuser, $dbpasswd)){
mysql_select_db($dbname, $db);
} else {
echo mysql_error();
exit;
}

Re: [PHP-DB] problem with LOAD DATA INFILE for date format
There may be a better way, but in migrating from Filemaker to MySQL, I encountered similar problems. My solution was to pass the data through Excel and use that to convert the dates into the required format (CTRL-1, Custom, -mm-dd). Of course, you ned to watch out for those nasty ' ' ' that Excel puts around any cell containing a comma. So you might need to filter the output from excel in a text editor too but if its a one-off, its worth it. george - Original Message - From: Hendra [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, January 25, 2002 5:09 AM Subject: [PHP-DB] problem with LOAD DATA INFILE for date format Hi, I have a sample data like below in text file (policy.txt).

Re: [PHP-DB] convert yyyy/mm/dd to mm/dd/yyyy, how?
Sander,
I'm also in Europe but here in the UK we prefer dd/mm/ and I've cobbled
together a couple of functions to handle this for me.
function dbdate($input)
{
$today = explode(-,$input);
$month = $today[1];
$day = $today[2];
$year = $today[0];
$p_date = $day . / . $month . / . $year ;
return $p_date;
}
function revdate($input)
{
$today = explode(/,$input);
$day = $today[0];
$month = $today[1];
$year = $today[2];
$revdate = $year . - . str_pad($month, 2, 0, STR_PAD_LEFT) . - .
str_pad($day, 2, 0, STR_PAD_LEFT);
return $revdate;
}
I've stored these in a file which I include and any call to the db to
display dates uses the dbdate() function and if I want to insert or update a
date then I use the revdate() function.
There are probably better ways to do this.
Hope this helps.

Re: [PHP-DB] grabbing id from new record
I am sorry, I was not clear in my original request.
The id is auto-incremented. I want to grab the id so that I can use it as
part of a redirect

desc limit 0,1;
$result2=mysql_query($q2) or die(q2 failed);

$recid);
header($redirect);
As I said, it works but maybe there's a better way.
George
What about Auto_increemnt field ??
Your's id can be auto_increment field. for example:
create table dupencja (id int(7) auto_increment not null, primary
key(id));
so when you insert records:
insert into dupencja values('') - id will be 1
insert into dupencja values('') - id will be 2
this is auto_increment, so your trick isn't need.
More in manula of mysql.

Your's id can be auto_increment field. for example:
create table dupencja (id int(7) auto_increment not null, primary
key(id));
so when you insert records:
insert into dupencja values('') - id will be 1
insert into dupencja values('') - id will be 2
this is auto_increment, so your trick isn't need.
More in manula of mysql.

Subject: [PHP-DB] grabbing id from new record
Hi,
Is there a way to grab the ID (from ID field) while INSERTing a new
record?
I am currently doing a separate INSERT then a SELECT query to find the
most
recently added record by that user:
select ID from table where user = '$user' order by ID DESC limit 0,1
This does the trick but it may not be the most efficient way.
George

Re: [PHP-DB] grabbing id from new record
Sam, Thanks, I got the mysql_insert_id() tip a few seconds earlier. However, my alternative method (which I will now drop in the interests of efficiency) is perfectly safe. It is impossible for the same user to go and create another record in that verys small interim period between the two queries. That was why the WHERE user='$user' was there. George - Original Message - From: Sam Masiello [EMAIL PROTECTED] To: George Pitcher [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, January 14, 2002 3:21 PM Subject: Re: [PHP-DB] grabbing id from new record That actually isn't a safe way to do it. Consider the following scenario: Insert A occurs generating row Y in your table. Insert B occurs generating row Z in your table. select occurs (after insert A) to grab last ID inserted...your result is the ID from row Z. select occurs (after insert B), and your result again is the result ID from row Z. So, in both cases you will get the ID from insert B, instead of your intended result (first select gives the ID from row Y and the second from row Z).

Re: [PHP-DB] Concept help required
David, =I'm feeling a little 'at sea' here, because we had established that you want to learn more about joining, yet you recognise the word normalisation straight off. I don't want to insult you by 'talking down'/teaching grandma to suck eggs... Please be sure it is not another one of those words that has a particular definition in the relational world, but was subjugated by wiley marketing people at FM to mean something 'just a little different' (alternatively that my ignorance of the product is the issue). Feel free to realign my approach... No need to feel at sea. After an earlier response from either you or Miles, I read up on normalisation. =Continuing on, in such a situation I am always inclined to try to 'cut corners' (against the 'standard' structured analysis/book approach) - bet this comment gets some of our list colleagues gagging, already thinking I'm long-winded in my methods. Because, as an outsider, I would not have such an intimate understanding of the data items and their inter-relationships as you do, I would probably attempt to take the existing data structures (the tables, and the list of fields/columns in each) and restate/extend these into something called a ELH diagram (entity life history) - the theory of which you will find in any competent structured analysis and design or SSADM text (the latter relevant to your location, SSADM being a British Government initiative, if you'll pardon the oxymoron). I have done these flow charts in the past to demonstrate how my current system should work at a higher level. =The purpose of an ELH diagram is to take a piece of data (in your case, because we are assuming/checking normalisation, I'd 'cheat' and work at the table level - rather than something more atomic like the data-item level). Once again we draw boxes (I have some wonderful s/w for doing these tasks, but it is M$). A single Visio? label/box at the top, featuring the name of the data-unit, and I would guess a minimum of three (must be my favorite number!) boxes in the next row, representing the arrival/creation of the data, its use within the system, and the removal of the data from the system once its usefulness has subsided, respectively. The third row of boxes represents the actual, individual events in the life-cycle/daily operation of the system, and how they alter/update/use the data. Lines drawn between the boxes show how these events relate and where there may be some iteration. =This is an analysis/checking tool. As such it bores the socks off most techies. However it is most useful to ensure that data is being used properly, and for a consistent purpose. In theory it can also be used to check the data structure because by following the uses to which a piece of data is put during its life, you can ensure that it is being represented using the 'best' data type for the purpose. It can certainly be used to ensure that you have the best design of relationships between multiple data items - both in the single table/normalisation sense, but most especially in the relationships between tables. As I go, my diagrams accumulate a bunch of notes around the margins with lead-out lines heading back into/from a point in the diagram - reminding me to check things as the design (or in your case, verification) proceeds. Methodically iterating across dozens of diagrams, the notes are removed - and the system data coalesces. =One of the great things about doing this, is that in examining where the data is coming from, going to, and how it is being used; you are also making a list of all of the db queries that you will need to contain within your system - yes you've guessed it, I have another bunch of boxes scattered around my diagrams (in a different color, just to be petty, er, pretty) which note these needs. If you 'get into' a design book, they will talk about other related diagrams, eg data-flow diagrams, which would normally be used to contain much of the info I'm putting into margin-notes - like I said, I'm short-cutting and I think you'll also get away with it because of your level of knowledge. Feel free to disagree (either way). I will be going through the stages you have mentioned to map out the processes and data requirements. I think that I know the process enough to do this without reference to the 'users' considering that at present this is for purely self-development purposes. =Once the diagrams are finished, or for a little light relief (of the diagram boredom) as I go along, I then use a db admin tool for MySQL to start building the SQL code, and testing them against some sample data. Yes, I could use the MySQL command line, but I am a fan of MySQL-Front because as well as the stark content of diagrams and the code-view of the SQL DDL statements, the package gives me a visual representation of the columns/data - another opportuntity for any incongruities to penetrate this thick skull... Oh, and you've probably guessed

David, =ex-Navy guys are always at sea - however they never let me near the ships, but I guess that's another story... ex RAF myself (almost 30 years ago though), so I suppose I might be all 'up in the air'? level). Once again we draw boxes (I have some wonderful s/w for doing these tasks, but it is M$). A single Visio? =yes - but as part of my venturing into LAMPs, I have been pointed to an equivalent package under Linux. =understood - and so whilst you may not 'improve' the system design (the primary objective when developing on a 'green field' site) it will help in your conversion to SQL/relational technology, as per below. I'm sure it will. =correct MySQL does not CURRENTLY have stored procedures, but it is under active discussion (too late for us, but then...). =many people have a very shallow understanding of SQL - particularly [he says generalising like crazy] people who 'fall into it' from (say) PHP programming. Indeed my own initial training course [mumble, mumble] years ago majored on SELECT, charged through INSERT and DELETE, and settled lightly on DML. However there is enormous power in the SELECT statement that belies the usual course topics of SELECT *... and SELECT colName, colName, ... and a bit of format control/changing the column names/labels. In my training course, and many others I've seen since, token gestures are made so that even throwing in MAX(), MIN(), and AVG() seems more an illustration of (the more narrow) GROUP BY clause than it does of the SELECT statement. [rant, rave,...] This shallow understanding means that 'they' will tend to do too much in PHP (assuming they know it better) in preference to SQL - at a cost of efficiency/execution time. =let's make this answer a 'game of two halves': firstly, if you followed my earlier point, after producing ELH diagrams, (my)/the next step is to start writing SQL queries. Thus one tries to pack as much functionality into the SQL statement, as is possible. Each SQL query will feed some response 'back' to the PHP code (that in the finished product, will first call it). Thus if you throw together the system's SQL calls in a previous development step, the only PHP functionality required is that which cannot be accomplished within MySQL - so my terminology may be flawed/deceptive, it is not that I'm taking stuff out of the PHP code (I haven't written any yet/at this stage), it's that it never gets in there in the first place! Remember the mantra: prevailing wisdom says that if you have a choice of doing something in SQL or PHP, do it in SQL. =there's an interesting problem on the list (in fact both PHP and PHP-DB) posed by Brian Tully need help looping through each record with a query -stumped. It is a much smaller/self-contained example than your own. He has presented his 65-line, mainly-PHP code in his statement of the problem. It provided a brain-starting challenge for me this morning, and I have opened my big mouth to suggest that we could get it down to a much less complex single SQL call and one or two nested loops of PHP. To do this, I have requested some clarification of the business rules governing his case. If it suits you, and assuming he gets back to me, I will work through it. Could we then use this as an example of how to shift functionality out of PHP (the 'middle box') and into SQL (the 'left-hand box')? Yes, please do. But if I could interject with a sub-concept question. Much of what I will be scratching my head about can probably be achieved with SQL as it pertains to data held. Can this fuctionality be built into MySQL or is it more a case of still doing it all in SQL but the SQL 'script' resides in the .php page? Just trying to see the trees instead of the wood.

Air Traffic Control was my area, though we did have to put up with some of your lot when Ark Royal was in dock as we were a Buccaneer base. =Sorry, misunderstood the 'level' of your question/comment... =Yes you are correct, the SQL code 'resides'/is kept within the PHP code. Borrowing an example (and editing a little) from Brian's post: $query = SELECT Month, Score FROM scores WHERE Username = '$Username' ; $result = mysql_query($query2) or die( Cannot execute query . mysql_error () ) ; =This is PHP code. The first line of which builds a SQL SELECT statement where the contents of the PHP variable $Username will be substituted inside the single quotes, eg SELECT Month, Score FROM scores WHERE Username = 'George Pitcher' =The second line throws the query at MySQL and receives two results by return. Firstly the logical: did the call work or not? which may fire the 'or' clause (returning an error msg and number); and secondly the handle of the MySQL resultset. (the next step being to retrieve the actual data, as required/appropriate from the resultset) =So at the code-level, the SQL commands/script is/are contained within the .php page. =At the logic level, the functionality to retrieve only the single record (that fulfills the stated criteria) from amongst all those in the database, is contained within the SQL command. =but I'm still not sure which one is wood, and which trees! =Ok now? Yes, that clarifies a lot. I can stop looking for some place where it might exist in MySQL and concentrate on the design until you are ready for the SQL building.

David, =Prevailing wisdom in system design suggests that the data should be 'designed' first, and 'code'/processing only later (relational or structured design philosophy, even object-oriented design). Accordingly I recommend considering which parts of your current files should be converted into MySQL tables, and what might need to be added/subtracted to ensure that the relationships between tables is adequately expressed/because that makes other 'old data' unnecessary. As you would seem to have identified your data, and grouped/categorised it into tables, you might be able to go straight into the process of 'normalising' your data - a series of steps/techniques which enable you to analyse the data and structure it into a 'relational' form. (if you are not familiar with this term: it's back to the books) Actually the Filemaker system is fairly 'normalised' having been developed over a couple of years, our previous web developer (commercial partner) pulled out of our service an I stepped in to deliver the goods and in doing so, went through the analysis and re-design process. It may well be that there could be some marginal improvement in doing it again. I'll have a look anyway - its part of the learning process. =Have I misunderstood? It seems to me that you are not offering this data to the web, ie I can't get to it; you are only offering it to the copyright fee-paying clients. Hence the publishers' argument seems illogical/ignorant... Yes, exactly, but they control what happens and we are not mature enough as a service to hit them over the heads yet. I run a dual site with a main 'Live' service and a Training service allowing users to play with the processes before they get near the real thing. =and now a third environment: for development, and a fourth: for system testing...

Re: [PHP-DB] Concept help required
DL Neil (I presume you have a first name tucked away inside there), Your comments are appreciated. I am becoming more and more comfortable with what I am doing with MySQL/PHP. With reference to the 3-box trick, I thought that the bulk of my work would be inthe centre box but as you point out that would be inefficient if the work can be pre-processed in the RDBMS box. A simple explanation of my Filemaker system follows. But first, a description of what the service provides might help. Our members (50+ uk universities) can request material (usually book chapters or journal articles) to be delivered electronically (or rarely, by paper) to their students. We handle copyright clearance through the UK rights agency (CLA) and through publishers/authors. We pass the prices back to the clients via the web interface and the client accepts/declines. We then source originals from the British Library which are digitised by a bureau and put into PDF before a front page is attached (currently automated using Applescript but hope to use PDFlib in future) and delivered to the university. We invoice monthly for items completed, not by course. We have a success rate of 60% mainly due to the reluctance of publishers having their material mounted on the web. Now the system: (number of current records in parentheses) Transactions (15000+) [contains a record for each requested extract with workflow and cost information] Course (900+) [Holds data for courses such as student numbers, dates etc] Bib_source (6000+) [Book or journal data held here at title level] Bib_extract (9000+) [Chapter/article level data held] Publishers (18000+) [Rightsholder details data bought in] Customers (50+) [Client details] Buyers (200+) [Individuals who can make purchasing decisions at clients] Illustrations (150+) [Illustrations require special handling and there can be several per extract] Invoices (300+) [data taken from Transactions and Customers to produce PDF invoices] Userlog (4000++) [log of users accessing main system] Weblog (500+) [covers whole site and started in December] Staff (10+) [Staff names, addresses, emails etc] Scanrates [CLA-provided table to store pre-priced material - covers about 40% of requests] Helpdesk-general [General helpdesk alloowing LAN-wide staff access and direct responses to users] Helpdesk-transactional [As above but specifically set up to handle problems about individual transactions] I run a dual site with a main 'Live' service and a Training service allowing users to play with the processes before they get near the real thing.

In your case you are going for the PHP combination so I will be quite surprised if you 'run out' of functionality! The original Filemaker (FM) databases use calculations stored internally. You define a field to store the result of a calculation. This could be something quite complex or a static number (or string) or data from a related database. Filemaker requires a separate database to represent the equivalent of a table in standard SQL databases. Some calculation fields can be indexed and some cannot (esp those containing related data). I expect that I can replace these calculations with functions which I define. =it sounds as if you are still getting to grips with the advantages and power that SQL and relational databases bring to 'filing' tasks. There also is a terrible possibility of terminology pollution/confusion. When I last looked at FM (many, many moons ago), I consigned it to file 13 as being too much of a 'shoebox' style 'database', and my being more interested in something PC-ish that would run something more like a table-relational model (if not SQL), eg Paradox or even Access (make signs for protection and mutter incantations to ward off the evil eye...)

[PHP-DB] Concept help required
Hi all, In trying to learn PHP (and MySQL), I am attempting to replicate a database-web solution built previously using Filemaker Pro and Lasso (on NT). I am currently working with PHP/MySQL on NT and will be moving this to Linux before the end of January. Filemaker is able to perform calculations internally and therefore I guess I will need to write functions to mimic this externally. Am I right here? One of the features of the FMPro solution is that when a user is looking at a list of resources (in fact, university course packs) each row will display the number of associated records from the 'books' database. Now which is the best method to do this (speed/efficiency)? I have tried performing a row-level query on the related db but its very slow and times out before the second row can be displayed. Alternately, I could set the main db to increase/decrease a number field when adding or deleting books from the list. Which is recommended?

Re: [PHP-DB] Concept help required
Miles, Thanks for the response. My description of the Filemaker solution was very simple. In fact it is 13 databases with some containing up to 18000 records. At the centre is a Transaction database containing 15000 'book' records. Each transaction record contains a pack ID field and this is what is queried to produce the 'count' but its painfully slow. The MySQL version of this table contains some 160 fields. In practice, this db table will grow by approx 300 records per week as new transactions are added by users (all UK universities). I also have other queries which need to be carried out to produce the information needed to provide good feedback to users. For instance, each transaction has a 'state': unsubmitted, submitted and complete. I want to be able to show the state of the pack as 'unsubmitted' when all transactions are 'unsubmitted', 'partially submitted' when some have been submitted and others not, 'submitted' when all transactions have been submitted and 'complete' when all transactions are at the 'complete' stage. So with the overall count, that would be 5 queries and I can think of at least one other query which would be needed to cover another process. If a single query is taking so long, what will 6 do to my database's overall performance? Would indexing help?

MySQL doesn't have stored procedures, if that's what you mean. If they are really important you might want to consider PostgreSQL. Double-check the MySQL docs, and a newer version might have this. One of the features of the FMPro solution is that when a user is looking at a list of resources (in fact, university course packs) each row will display the number of associated records from the 'books' database. Now which is the best method to do this (speed/efficiency)? I have tried performing a row-level query on the related db but its very slow and times out before the second row can be displayed. Alternately, I could set the main db to increase/decrease a number field when adding or deleting books from the list. Which is recommended? Don't do the second. You're creating a maintenance headache. I'm no SQL wizard. Are you fetching information from a courses table, and displaying the number of associated books for each course to get results like this, w/o formatting ... The Athenian Galley U. Stroke 2 Grecian Roots and Folk Clothing C. Me. Bare 4 where the number at the end is the number of books for the course? select course_name, instructor_name, count(books) from courses, books where books.course_id = courses.course_id and (whatever other criteria you are using to select the course) But something tells me that won't work and I'm no SQL wizard.

Re: [PHP-DB] Concept help required
DL Neil,
Thanks for your response.
=As a general comment, it is always dangerous to replicate when shifting
platforms, better to reverse engineer
and then implement anew and taking advantages of the strengths of the new
tools. This particularly when moving
into the relational field...
Perhaps the use of the word 'replicate' was wrong. I am in fact
re-engineering based on my knowledge of how the whole operation is performed
(as I designed and built the original Filemaker/Lasso system) and trying to
preserve the look and feel of the web pages.
=you will need to describe the 'internal calculations' before this
question can be easily/sufficiently answered.
However many people fail to appreciate that the (My)SQL language offers a
lot of power/functionality. In your
case you are going for the PHP combination so I will be quite surprised if
you 'run out' of functionality!
The original Filemaker (FM) databases use calculations stored internally.
You define a field to store the result of a calculation. This could be
something quite complex or a static number (or string) or data from a
related database. Filemaker requires a separate database to represent the
equivalent of a table in standard SQL databases. Some calculation fields can
be indexed and some cannot (esp those containing related data). I expect
that I can replace these calculations with functions which I define.
=as you can see, without giving a little more information, it is very
difficult to give a satisfactory answer.
How about listing your table definitions/schema. Almost any retrieval
operation that does not select all of the
records in a table will speed up when indexes are employed. If speed is a
concern then that argues against the
earlier suggestion of PostGres.
I think that the table definition list would be far too long for this list.
Speed is an issue as at the moment I am doing all this under my own steam in
my own time (partly to extend my skills) and hope to be able to persuade my
bosses that this would be a beneficial move (they are very conservative).
Performance improvements would help.
=you are talking as if there are numerous queries. What's wrong with
performing a join, or am I missing some
significance?
No but I probably am. I have been working almost exclusively with Filemaker
for the past 7 years moving from Mac to Win NT in the process, with a short
flirtation with MS Access and ASP. I'm really a SQL newbie and am gradually
getting to grips with what is possible. JOINs are alien to me and I'll ned
to read up and experiment with them to see how they work and how I can best
use them.
Dates
I played around with my learning site over the holidays and found that
I was
not able to easily handle dates between the format required by users
(dd/mm/) and that used by MySQL (-mm-dd) and therefore I wrote
functions to parse the data both ways. All the example I could find on
Dates
used 'today' as the example. I want to be able to play around with
stored
dates. Is my function method the correct way or is there another way?
Yes - but why can't we convert the world to that oh-so-simple date
format
of year,month,day which sorts and indexes so beautifully and is
completely
unambiguous.
=Are you talking about functions implemented in PHP? Refer above, my
earlier comments on the power of SQL, check
out:
SELECT DATE_FORMAT( colNm, format ) FROM tblNm
in the manual at 6.3.4 Date and Time Functions. I'll be surprised if the
long list of 'formats' doesn't give
you more than enough options to keep (even Uni students) quiet!
I wrote my own functions to handle dates in the way I am comfortable with.
In dbdate() $input is the date pulled from MySQL and in revdate() $input is
the dd/mm/ date being grabbed from the users form data.
function dbdate($input)
{
$today = explode(-,$input);
$month = $today[1];
$day = $today[2];
$year = $today[0];
$p_date = $day . / . $month . / . $year ;
return $p_date;
}
function revdate($input)
{
$ztoday = explode(/,$input);
$day = $ztoday[0];
$month = $ztoday[1];
$year = $ztoday[2];
$revdate = $year . - . str_pad($month, 2, 0, STR_PAD_LEFT) . - .
str_pad($day, 2, 0, STR_PAD_LEFT);
return $revdate;
}
By the way, my site is for university staff not sudents.
I welcome any comments and hope to learn by implementation.
Regards
George

Re: [PHP-DB] newbie having problem
I did this directly into MySQL on the LinuxPPC box:
mysql select * from biz where
- ID LIKE '%AXD%' AND
- Type LIKE '%' AND
- Con LIKE '%'
- ORDER BY ID;
and this is the response:
++-+-+--+-+---+
| ID | Type| Con | Operator | History | Notes |
++-+-+--+-+---+
|DC | Piper Aztec | 27-4169 | | G-AXDC |
|DL | Piper Twin Comanche | 30-1856 | | G-AXDL |
|DM | BAE HS 125/400B | 25194 | | G-AXDM |
++-+-+--+-+---+
In these records, what is actually in the ID field is also being displayed in
'History'.
Not sure if this clarifies things?
