Re: [PHP-DB] Logicproblem in WHERE statement

You may get duplicate records (for people who are female and from Canada) so you may want to use DISTINCT as well. =If all you want to do is to 'highlight' people from Canada, whilst having a query that gives a worldwide resultset, try: SELECT *, IF( country = 'CA', 'Canuck', 'Normal' ) AS highlight FROM table WHERE sex=1; =Regards, =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP-DB] sorting on the first 8 digits....
John, Ok, I did something stupid and now I am paying the price... =boy am I glad that I'm not the only one in the world! How come the 'people' who extract these prices don't accept Mastercard? In an internal database that tracks the time and date something happens on our site, I mistakenly forgot to use leading zeros in the 24 hour column(s). So, anything that happens between 1-9 am are all short by one digit. Now, I need to create a report that shows these transactions in the order that they happened. The answer to this problem should be as simple as adding a zero to the end of all records that are short one digit. But, for reasons that I won't explain here, that isn't possible. So, my question is this, is there a way to do a database call that would select all the records but allow me to order them based on the first 8 digits only? If you would like an example, I need the following two numbers to come up in the order listed. 20011012182929 200411322 =you don't mention the column format, so from the example data I have assumed that it is integer rather than string (or MySQL timestamp). =as you observe, if the values are sequenced according to string rules, it all works for you (left to right, byte-by-byte comparison), accordingly anything you do to cast the values as strings will solve the problem - until you get across to the hours 'columns'. =so using only the first eight character positions of all the records: SELECT * FROM tblNm ORDER BY LEFT( colNm, 8 ) =this will separate the days neatly, but all of the records for a particular day will be in a non-predictable sequence. =you could get really clever and replace the LEFT() with an IF(): if colNm contains 16 digits then use the (string) value, as is; else if colNm contains 15 digits then use a concatenation of the first 8 character-positions, a zero, and the remaining 7 character positions; else (you have more data integrity problems than your credit limit allows) =the effect of this would be to (logically) restore the missing zeros and sequence the records by day, hour, minute, and second. =Of course, it would be better to do that as an UPDATE to correct your data, and then use the 'normal' SQL query, but you did say... =thanks for this morning's brain-teaser to get the old grey cells lined up... =ok? =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[PHP-DB] select into array
Hello everyone! I have the following table: |name |-- |n_id |n_name |ns_id --- I do a select: SELECT n_name from name and I want to put all selected n_name values into an array (say it names) How can this be done?? Thanx in advance.
Re: [PHP-DB] select into array
George,
Whether you can select into an array directly depends on your database.
In any case, PHP executes database queries and returns a handle or
container which is accessed as an array.
Here's the example from
http://www.php.ca/manual/en/function.mysql-fetch-array.php
?php
mysql_connect($host, $user, $password);
mysql_select_db(database);
$result = mysql_query(select user_id, fullname from table);
while ($row = mysql_fetch_array($result)) {
echo user_id: .$row[user_id].br\n;
echo user_id: .$row[0].br\n;
echo fullname: .$row[fullname].br\n;
echo fullname: .$row[1].br\n;
}
mysql_free_result($result);
?
If you want a tutorial on this, Julie Meloni has some really good examples
at http://www.thickbook.com and there are others at DevShed and WebMonkey.
Cheers - Miles

Re: [PHP-DB] mySQL administration on Linux through NT
Jerry, For a command line interface, you can use either putty or TerraTermSSH. I prefer the former and it's available at http://www.chiark.greenend.org.uk/~sgtatham/putty/ . The latter is more Windows-ish. For a Windows-like interface, through a browser, there is phpMyAdmin, and others, but I've never used them. Those who have seeem to favour phpMyAdmin. Generally if my query isn't working in a script I need the mysql console to test it. Thus it's either login using putty, if the server's remote, or roll the chair across to the other desk.

[PHP-DB] Authentication
I have a successful website with authenticatin and logons. There are sections that I allow anyone to get to, but the others have to be authenticated. This site is not using frames at all. its a page by page, with the unit that does the authentication and sessions being included in each page. I've taken these same units to another site. I altered the pieces neccesary to hit the new sites database and users. This site is using frames. the outer frames are not using the authentication or sessions. However, internal pages do. As I enter a section that needs a logon, it prompts me. Then it goes to the correct page. But the next page it goes too, it wants to get a logon again. These pages are in a row, and they all use the same sessions stuff that the other site uses. I know that they all have to include the same units, so once it needs to logon, it'll prompt that, but it should pass this session info from here to there, and not have to logon again. Its driving me nuts. The only thing I can think of thats different is the frames. I even took the same code from the other site ( the one that does work without frames), and plugged it in. So the session logon was for the other site and other db. It'd prompt me each time too. I am not sure what to do now... help please. When I first set up PHP my sessions did not work. What I eventually found was something to do with my php.ini file on how it deals with sessions (ie. where they save them, etc) This is some stuff from my php.ini file which i found useful (and made it work, I think) register_globals = true session.save_path = /tmp session.use_trans_sid = 1 session.auto_start = 1 Some of it might not be the solution but I think the session.save_path directive is what makes it work. For better definition of what these things do, look in the php manual (Chapter 3. Configuration).

RE: [PHP-DB] Re: Moving from MySQL to MSSQL Server 2000
There are few things you should consider; perhaps you already have. You may not be replacing the OS of your Web server but you will be adding a new OS for the database since MS SQL only runs on Windows. So now your site will have a Solaris / Apache piece and Windows cluster running MS SQL. I have run configurations like this and they do work however if your fundamental goal is better reliability I suggest to be careful about MS SQL. My experience (not wanting to start any flame wars here) has been that MS SQL is not as reliable as some of the bigger names such as Informix / IBM and Oracle. All of those also run on Solaris which means you could still only have one OS. That may or may not be an advantage to you. The other issue to be very careful about regarding MS SQL is it is not supported on Solaris. So if you have an issue where the database appears to be functioning normally yet your Apache Web server cannot retrieve data from the DB Microsoft will have nothing to do with helping you fix this. It is an unsupported configuration; the connectivity products you will use, whatever they are, will not come from Microsoft nor will any help. But to answer your specific questions: ODBC, JDBC are not the only ways to move data from the database to Apache but they are the most popular ways because they're easy to use and they do work very well. Also check out freeTDS (tabular data stream) and a product called OpenLink, there are others try Web search from your favorite search engine. A few months ago we did a benchmark and we found JDBC to be faster than the Microsoft client or ODBC. In our case we believe this was because of the way that JDBC returned results in larger chunks which matched our needs for that App. Your mileage may vary; these things depend on your application and a particular versions of the software and combinations of the software using. Nothing beats having the time to try a couple different combinations and see which works best for your situation. I don't think there any particularly special points you need to consider because you're using MS SQL but as I've said each application can be different and have its own unique needs. Good Luck, Frank Well, My Site runs now on Solaris. Both the front end (Web Server / php code / Apache) and the Database (Backend server). We had some problems with Mysql and we don't find it 100% reliable for such a busy site. We also want to use a db cluster for high availability (we are talking about $200,000 of hardware and software for the change). The code will still run on Apache / PHP / Solaris so there is no change in that. Only the access to the Database will change.

[PHP-DB] MSSQL - PHP4 on Win 2K - will not run a query.
Hello all, I'm having a problem getting PHP to run a query against a MSSQL 7 database. I have installed PHP, the MSSQL client tools and the php_mssql.dll all according to the documentation. PHP will connect to the database just fine. But if I send the query to execute it will never return, no error, no results; the browser will eventually time out. The query will run from fine from the client tools on the server. Here is the simple code on trying to get to run: ? /*All variables have been set already*/ echo h3Begin/h3; $linkID = mssql_connect($hostname,$username,$password) or DIE(DATABASE FAILED TO RESPOND.); echo h3Connected/h3; mssql_select_db($dbName) or DIE(Table unavailable); echo h3DB Set/h3; flush(); sleep(20); /* Sleep for debug - to allow me to see php loggin in db */ die(); / I can get to here - no problems - sp_who inside the MSSQL db shows I'm connected successfully and am using the DB I've requested. If I remove the above 'die' or move it to just after the mssql_query statement below this page will never return. / $query = SELECT getdate(); $result = mssql_query($query, $linkID); echo h3Query Submitted/h3; /* code to retrieve and display results goes here */ ? So can anyone give me some hints? Is there a special place to look for error messages? The database server doesn't think any error or query has happened and apparently the Web server is waiting for the database server to reply.

[PHP-DB] Count
How do you add a count feature to a link. I can get stuff from the db but want to know how many times it's been read or click on?
Re: [PHP-DB] Re: [PHP] mysql_insert_id?
Hi Martin, 2 because the (function argument) controlling feature is the connection, it is not possible for another concurrent user to 'steal' your ID or influence the ID returned to you - it's all yours! Ok, assume you are correct, but what if you are using persistent connections (ie pconnet)? =According to the manual (Chapter 22. Persistent Database Connections) there is no difference in functionality between persistent and non-persistent connections (only a (possible) difference in efficiency/response time). Thus use of persistence does not buy you into other issues. =If I leave it there, you're going to come back with another question, aren't you!? =This is my understanding. A connection is set up to enable communication between the PHP script and the RDBMS. The connection is exclusive to the script and only lasts the life of the script. Now let's look at the word script. Each user/browser is processed within the (Apache) web server as a separate child process. If the process calls for PHP processing, then what happens in one process within the web server is kept quite separate from what's happening in another process. This applies even if they both use PHP, and even if they are both running the same PHP script, and even against the same MySQL db/tbl, ie because of the way Apache works, there is no 'sharing' of connections/cleverness in a bid for extra 'efficiency'. =Thus there is no way for my (connection) use of the db to interfere with your (separate connection) use of the same, in terms of AUTO_INCREMENT, INSERT IDs, and suchlike. =I'd really like to hear from someone who can talk more authoritatively on the subject though! =Regards, =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Hi Jimmy, 2 because the (function argument) controlling feature is the connection, it is not possible for another concurrent user to 'steal' your ID or influence the ID returned to you - it's all Ok, assume you are correct, but what if you are using persistent connections (ie pconnet)? don't worry, persistent connection is per-child-process basis, so concurrent users will use different connection to DB. the only problem i can think of might occur with pconnect is, last_insert_id() will return you the last inserted ID from previous 'session', not current 'session'. to prevent this, you should call last_insert_id() only when your INSERT query executed succesfully. =Of course a right-living boy like me, cannot conceive of why one would look up LAST_INSERT other than immediately after the INSERT/UPDATE command... =However this is an interesting thought and you are right. There are differences between the MySQL LAST_INSERT_ID and the PHP MySQL_ =The MySQL manual (6.3.6.2 Miscellaneous Functions) talks about Returns the last automatically generated value that was inserted into an AUTO_INCREMENT column...The last ID that was generated is maintained in the server on a per-connection basis., and a number of other if-s, but-s, and maybe-s that will get everyone going. =(However I believe it also answer's Martin's question!) =What I have noted is that the PHP manual (http://www.php.net/manual/en/function.mysql-insert-id.php) works slightly differently (and possibly more simply), as well as emphasising the immediately after relationship between this call and the preceding INSERT. An interesting point here and that is that it takes care of Jimmy's concern: what happens if the INSERT query was successful. =I think I prefer the PHP approach - and it is probably more efficient/quicker (from PHP) too. =Further thoughts? =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Most probably the returned value would be wrong, because it will return the last_insert_id of previous INSERT query (from previous 'session') =right living was a (poor) joke following your previous post's .SIG file aphorism...not a criticism. Now that you have mentioned the possibility, I can imagine the odd (very odd) use for collecting an ID from a preceding interraction (with the database). =session is not the correct word/its use is potentially confusing (perhaps that's why it's in quotes?) - persistence refers to the continuing connection between PHP and MySQL. =What I have noted is that the PHP manual (http://www.php.net/manual/en/function.mysql-insert-id.php) works slightly differently (and possibly more simply), as well as emphasising the immediately after relationship between this call and the preceding INSERT. I might be wrong, but i think PHP's mysql_insert_id() must be using MySQL's API function call. Meaning, it will return whatever value MySQL return. Or in other word, mysql_insert_id() and last_insert_id() will return the same result. I have look thru the manual link above, and i think the phrase immediately after in the manual is more to advise the user to do mysql_insert_id() immediately after the INSERT query, because last_insert_id value might get overwritten by the newest one. the immediately after phares in the manual doesn't mean that PHP's mysql_insert_id() function is somehow tied to the previous/last INSERT query, so that if the INSERT fails then mysql_insert_id() will intelegently return the correct value. just my 1 cent =Agreed it would seem perfectly logical that the PHP function simply calls the MySQL source function. However it is also possible that in order to save time the LAST_ID information is built into the resultset coming back from the INSERT - thus when mysql_insert_id() is called PHP would not need to go back to MySQL/last_insert_id(). On the other hand, the apparent differences between the two manuals may simply be in the expression of two authors... I don't know [but would welcome competent advice!] =the immediate advice is transparently logical best practice. =I'm not sure that I've understood your last point. The comparison/difference, as I read/understood it, is that if the INSERT works then both functions will operate correctly. However if the INSERT fails, then MySQL's last_insert_id() will return the ID of the last record successfully inserted during the connection (whenever that was) - without necessarily any recognition of an immediately preceding failure. Whereas PHP's mysql_insert_id() is keyed to the resource identifier and returns zero if the **latest** INSERT failed for some reason (and the rationale for my earlier comments/comparison). =My thinking is that the PHP rationale makes the most/safest sense to me, and if I'm 'in' PHP it seems best to stick with that 'mode' than to go 'out' to MySQL to find the 'same' answer. =Intriguing stuff, =dn -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP-DB] Count
Afterthought -- you could make this self-maintaining by doing a select for $PHP_SELF and inserting the record if mysql_num_rows() returned 0. Downside is that it would add greatly to the overhead. Miles At 04:42 PM 1/16/2002 -0400, Miles Thompson wrote: Barry, Before leaping to the wrong conclusion, what exactly do you want to count? You can derive the number of times a page has been fetched from your web logs. Alternately, you could add a table to your database, and at the top of the page the link points to, after you've established your database connection, etc.: $sql_count = update page_count set views = views + 1 where page = '$PHP_SELF' ; mysql_query( $sql_count ); You'll have to add a record for each page to the database, and by now you know how to create tables etc. Justwatch out for reserved words and function names; when I first typed the query I used count in place of page_count. Views and page probably aren't such a hot choices either. Fetching the counts for the pages involves nothing more than issuing select * from page_count and you'll have a per page count of all the clicks to each page.

[PHP-DB] Unique Results?
Hi there everyone,
(Sorry if you got this twice, I don't think my mail server posted it earlier).
I use the following code to populate a dropdown box from a MySQL database:
$db = mysql_connect(localhost,^^^,^^^);
mysql_select_db(mydb,$db);
$result = mysql_query(select country from search);
if ($result)
{
echo SELECT NAME='country';
while ($myrow = mysql_fetch_array($result))
{
echo OPTION VALUE=\.$myrow[country].\.
$myrow[country]. /OPTION ;
}
echo /SELECT;
}
However, this database has multiple country names the same (Aswell as unique ones) how
can I display just ONE of each entry? IE: say there are 5 africa, 3 britain etc .
I only want the list to show 1 of each and not 5 and 3 and so on - how is this
possible? Please help :-)
And thank you to everyone who helped me with an earlier enquiry, it's very appreciated
:-)

Assuming that $pic is 0, then $new_pic is 12, so you're selecting with

Note that if the select statement gives you other than 6 or 12 images

To find out if $new_pic pointed to a valid image you would probably need
to do a select count(*) from ab to get the total number of records. If
$new_pic is less than the count, then show the link.

[PHP-DB] Searching a variable
Hi there everyone, Thanks for all the help recently everyone, it's very appreciated. I just have one last question if that's ok :-) I have a string taken from a form, now this string could contain 1 word or it would contain 10, what I need to know is how do I search a DB for each word in the string? I have a simple search engine which works great for works next to each other in the DB but I need it to search each entry for ALL words entered, whether they are next to each other in the DB or 3 words apart, how can I do this? Thanks for all your help. Regards Chris Payne www.planetoxygene.com
RE: [PHP-DB] Searching a variable
i don't doubt that there are probably better ways of going about this chris,
but you can do something like;
?php
$words = explode( , $searchText);
$query = SELECT * FROM table WHERE ;
foreach ($words as $word) {
$query .= field LIKE '%word%' AND ;
}
$query .= field!='' ORDER BY something;
$results = mysql_query($query);
?
as for ranking the results - i have heard people mentioning the fulltext
index in mysql, and there's some cool calculations floating around in the
archives somewhere, but they escape me at the moment and i haven't got
around to implementing a decent search engine yet :)

// I have a string taken from a form, now this string could

// is how do I search a DB for each word in the string? I have
// a simple search engine which works great for works next to
// each other in the DB but I need it to search each entry for
// ALL words entered, whether they are next to each other in
// the DB or 3 words apart, how can I do this?

// Thanks for all your help.

Re: [PHP-DB] Re: Redirecting to a new page
And while 'gurix' is correct, the function you're probably looking for
is 'header()', as in header(Location: admin.php);
Cheers

a better way is to include your admin pages.
if ($myrow[Admin] == Y){
include(admin.php);
}else{
include(user.php) ;
}
so you can also include at the top of this example a general header with
menu's etc.

yeah, i know this, but i'm just trying to get this to work before i add
some
security in there - passing sessions through etc to ensure they're logged
in
as admin etc.
it doesn't really have to be that secure for what i want anyway, but
probably a good job you pointed that out ;)

Please note, that this is a very insecure way of determining which page a
person gets to view. All they would have to do is enter the admin.php url
in the browser and they get admin access even if they are not admins.

Can't find the right instructions on php.net, basically, i want a page
where
someone logs in, and then according to the database entry for them,
either
they are an admin user or a normal user, and it should then send them to
a
page depending on which they are.
I've accessed the db ok, and checked which they are, then i've used
if ($myrow[Admin] == Y){
print Location:admin.php;
}else{
print Location:user.php;
)
this doesn't sem to work - just gives a blank screen with the standard
html
headers and footers, rather than the desired location page.

Re: [PHP-DB] PHP-informix-Apache undefined symbol
Fernando, First of all, where is libphp4.so located? You may have to copy it into that directory. On my system it's in /path/to/apache/libexec. Try that and see if apache will start. If the libphp4.so error is gone, but the other remains, try this. In your /etc directory is a file named ld.so.conf, which contains the paths to the locations of various dynamic shared objects(DSOs). For example mine contains /usr/lib /use/i486-linux-libc5/lib /usr/X11R6/lib -- down to here all this stuff was installed when Linux was installed /usr/local/pgsql/lib /drv2/bin/mysql/lib/mysql The last two I added after installing PostgreSQL and MySQL. So if I cd to /drv2/bin/mysql/lib/mysql and execute ls, I'll see a number of files, each with an .so extension, or .so as part of the file name. Some are symlinks. Add the location of the DSO for informix to this file, then run the command ldconfig. You should then be able to start Apache and everything should work OK. One more thing, did you follow the INSTALL instructions on copying and renaming php.ini-dist? If not, do so and restart Apache. Hope this helps. There is also a PHP-INSTALL list where you will be better off if the above doesn't bring results.

I don't know. How do I set this? I was reading the online manual about
http_get_vars and it didn't help, and doesn't have any examples.
I was assuming that the $pic variable was set by the HTTP get request
since your link below is in the form:
a href=\index.php?pic=$new_pic\.
When the target script starts after being called like that the value in the
global variable $HTTP_GET_VARS['pic'] will hold whatever $new_pic was set
to in the reference. Assuming you have register_globals on, then the global
variable $pic will also be set to the same value.
Otherwise $pic will be uninitialized and should evaluate to 0.

[PHP-DB] Re: Session and authentication questions in frames
I realized that I was not doing a page_close(); In the other site, there is a footer that all pages use, that automatically does this for me. I just forgot it. It had nothing to do with frames. Just a dumb thing that I forgot. Tjaybelt [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I have a successful website with authenticatin and logons. There are sections that I allow anyone to get to, but the others have to be authenticated. This site is not using frames at all. its a page by page, with the unit that does the authentication and sessions being included in each page. I've taken these same units to another site. I altered the pieces neccesary to hit the new sites database and users. This site is using frames. the outer frames are not using the authentication or sessions. However, internal pages do. As I enter a section that needs a logon, it prompts me. Then it goes to the correct page. But the next page it goes too, it wants to get a logon again. These pages are in a row, and they all use the same sessions stuff that the other site uses. I know that they all have to include the same units, so once it needs to logon, it'll prompt that, but it should pass this session info from here to there, and not have to logon again. Its driving me nuts. The only thing I can think of thats different is the frames. I even took the same code from the other site ( the one that does work without frames), and plugged it in. So the session logon was for the other site and other db. It'd prompt me each time too. I am not sure what to do now... help please. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Yes it is on.
then the global

Makes sense
Otherwise $pic will be uninitialized and should evaluate to 0.
So, I guess I have to set the variable to 0 first when the first page is
loaded, then add 24 (or 12 or whatever) to for the link to the next page. So,
with that in mind I added this
$pic=0;
before
$new_pic=$pic+12;
but that just caused it to reload the same images each time next was pushed.
So, now that I appear to be a total dummy, and the manual doesn't provide any
examples, and the two books I have don't seem to be able to help also, would
you mind helping me a bit more? I'm I going about this next page stuff all
wrong, is there a better way to do it?

[PHP-DB] phplib authentication questions
I use phplib's session management and authentication. Adding my own info into it where necessary. So, it does ask to login when appropriate. However, every once in a while, I get errors in insert. Its an error in the table with a duplicate entry. Its trying to insert a record that is already there with a primary key. I could remove the key, but i think that it should stay there as is, and I should figure out why, from page to page, I will get the same data trying to be inserted. I am wondering if anyone else is having these issues with the session stuff. thanks. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
