Re: [PHP-DB] Really weird problem: cross-server databasing *g*
Hi Markus-- It sounds like the provider that only allows local connections to their database went through some pains to protect their database. I suggest talking to them about your needs and not trying to circumvent their security measures. Maybe they have a system to open up their database for you for a monthly fee?

RE: [PHP-DB] Simple database error (SPACE)
DW was correct, Nagasea. The way to do what you want to do is to use the
urlencode (and perhaps the urldecode) PHP command(s). They are in the PHP
manual. I don't understand what it was that DB told you to do, so I cannot
comment on that, but the correct solution to your problem lies with urlencode.
Additionally, you will want to put quotes around the HREF in your anchor
tag. Perhaps if you rewrote your echo to something like this
(WARNING:untested!):
echo a href=\m_template.php?nick=;
echo urlencode($myrow[3]);
echo \;
echo $myrow[3];
echo /a;
Oh, yeah, and I broke it apart for easy reading. You could concatenate it
all in one big echo, but think maintainability.
Hope this helps,

Re: [PHP-DB] Database Transactions and HTTP statelessness
Hi BP-- There's also named cursors, but then you're going to have the problem of time. That is if you create a cursor FOR UPDATE and the user never saves the record or never cancels the edit (just closes her browser, for instance), then you're messed up and have locks floundering around in the db. In the HTTP stateless scenario, you really do want to do everything within the timespan of a single page-view. Dave Watkinson's suggestion for a column in the table to store some kind of version info (a timestamp or some other identifier that is updated every time the record changes) is a good one because it makes detecting an updated row a lot easier than comparing all of the original values from the originally loaded record to what's there when you finally go to save it. However, there may be times when Dave's suggestion can be overly restrictive. Let's say User A changes one column of Record R and User B changes a different column of Record R. In that case, the changes do not step on each other and probably should be allowed. Dave's suggestion for a per-record version identifier would kick out the 2nd person to save the record's edits with the this record has been changed by another user or process message. Perhaps that's correct for your application, perhaps it is not. You and your customer have to decide. That's why I tend to compare the originally loaded values of the fields that have been changed by the user with the fields as they appear in the record during the transaction that UPDATEs the record. If they're different then those fields really have been modified by another user or process and the transaction should be abandoned until the user gets a chance to review the situation.

Re: [PHP-DB] MySQL DB CleanUp Help!
Or of course one could compile PHP as a standalone and simply cron the script itself. No matter how PHP is invoked, though, IMHO scripts like this that require no human interaction should be a bit more robust than interactive systems. For example, one would probably want to code it to make sure the two instances of the same script cannot run simultaneously (and if an instance tries to run simultaneously, it should send an email to the admin and quit instead of performing its duties). Also error checking should email problems to the admin. As an alternative to emailing the admin, you could log status messages and errors to syslog or a file or a db table. Good luck!

RE: [PHP-DB] 2 Tables- 1 Insert Problem
Beyond that excellent answer, this is exactly the kind of situation where
transactions would be helpful (and in a lot of cases, mission critical).
So an expanded quasi-pseudocode rendition of olinux's answer could be:
$result_bt = mysql_query('[whatever it takes to begin a transaction]');
$result_1 = mysql_query($sql1);
if (!$result_1) {
$result_rb = mysql_query('[whatever it takes to rollback a transaction']);
/* whatever else you want to do, such as show an error message */
}
else {
$result_2 = mysql_query($sql2);
if (!$result_2) {
$result_rb = mysql_query('[whatever it takes to rollback a transaction']);
/* whatever else you want to do, such as show an error message */
}
else {
$result_et = mysql_query('[whatever it takes to commit a transaction']);
} }
If your implementation of MySQL supports transactions (and if it doesn't
then either change databases or web hosts), use them. It helps ensure the
integrity of the data. Please feel free to be more elegant in the error
checking...the above is just an example and would undoubtedly not be used,
even fixed up for syntax, on a production site.

Re: [PHP-DB] Re: enum !!
I applaud your efforts to learn SQL. I wonder, though, if the PHP-DB list the best place to learn SQL. I would think that a book or a web-based tutorial on SQL would be more conducive to your efforts. In the example you have given below, you would probably want to use LIKE. For example, SELECT * FROM test WHERE cat LIKE '%c%'; or similar ought to do it. Of course, I hope that the example is merely an example because if you really designed a production table like that then you wouldn't be taking advantage of the relational part of your relational database management system. So please keep learning SQL...it's a fantastic skill to have. If you have a specific SQL problem every once in a while there are those on this list who would undoubtedly enjoy helping out. Several beginner-level questions back-to-back, though, is way beyond the charter of this mailing list. The overall purpose of this particular mailing list is for discussions about PHP's ability to interface with databases. There may possibly be an SQL beginners mailing list on egroups or someplace similar...you might find an environment like that better than the PHP-DB list to help you with this stuff.

Re: [PHP-DB] sql problem
A quick glance suggests to me that it is a nonstandard proprietary extension to SQL that provides a way to set a kind of a variable and use it in a subsequent nonstandard proprietary SQL-looking statement that is awfully procedural. You'll probably want to either consult the documentation for the RDBMS you use or ask your question on a mailing list tailored to users and/or developers of the RDBMS you're using for a definitive answer. I can verify for you that it's not standard SQL, though. And it looks to me like they've gone and made what appears to be an extension that extends SQL so it has some procedural capabilities. There are problems on many levels with using SQL as a procedural language. The most obvious problem with using nonstandard proprietary procedural extensions to SQL is that (for example) you couldn't change backend database without recoding all your nonstandard SQL-looking statements. But I suppose they can be helpful because you couldn't possibly do the same thing with PHP (or perl, or a C program, or...) and standard SQL. Oh, wait. You can do procedural things with de-facto standard and standard procedural languages? Well, I'm sure there's a reason to have nonstandard proprietary extensions that add procedural capabilities to SQL or they wouldn't have them. (Note the clever way I mentioned PHP, since this is a PHP mailing list and both the question and the answer have nothing to do with PHP. It still doesn't bring it on topic, but at least I tried.)

Re: [PHP-DB] Treelike data: adjacency list or nested sets?
I almost always use "adjacency lists" along with another table for the actual categorization of the info (in your case, published articles).

Re: [PHP-DB] Concurrent update to database (PostgreSQL or MySQL) ??
As others have mentioned, this is a tricky thing to do. What others haven't mentioned is a way to do it. Let's say you just showed the update form to two users. It contains the fields that they are allowed to update and the values in those fields had been retreived from the database. Both users see a form like this: Today's High Temperature City: Detroit Temp (degrees F): 47 ( Submit ) The city field is not available for update (presumably the editor/user selected it off of a previous menu), and their task is to update today's high temperature for Detroit. One of the editors has information that the high temperature reached 49 degrees F, and the other editor has information that the high temperature has reached 50. (Perhaps one of the editors is overworked and hadn't gotten to enter the new high, or the temperature is changing very quickly.) So one of the people enter 50 and the other enters 49. Both hit submit. What needs to be done right at that moment to protect it from changing the value to 50 degrees (which is the correct, most recent, data) and then immediately changing the value to 49 degrees (which is now out of date)? Basically, you have to pass the original value to the script that is the ACTION of the HTML form. This way, you have the original value that may have been updated and the new value. The first thing the HTML form's ACTION script has to do is get the record from the database again. (Use SELECT ... FOR UPDATE if available, so the RDBMS might lock the row.) If the value you get from the SELECT is the same as the original value, go ahead and run the UPDATE to change the value to the new value. If not, then generate and display a screen telling the editor that the value has been updated by someone else...you can show the value and ask if they want to proceed with the update, but that's all up to you and/or your interface designers. This is all similar to how folks design old fashioned screen-oriented database systems (like with CICS).

Re: [PHP-DB] Best way to check if a query succeeded
I see you there's been lots of responses already, but there's an important
related bit of news folks might want to know.
Everyone who uses the mysql_affected_rows() should know that a bug was
fixed in 3.23.36 that evidentally reports affected rows incorrectly if
MySQL was compiled without support for transactions. Go to
http://www.mysql.com/documentation/mysql/bychapter/manual_News.html and
scroll down to section F.2.2. It's the 8th item in the list.
So shy away depending on mysql_affected_rows() for anything unless you're
absolutely sure you're running at least 3.23.36 or have transaction support
compiled in.

Re: [PHP-DB] help with a parse error
You didn't mention if the parse error was coming from PHP or from MySQL.
The PHP syntax looks okay to me at first glance (that is, a quick look
through indicates that there appears to be appropriate numbers of
semicolons and closing braces).
So perhaps the thing issuing the parse error is MySQL? In that case, I'd
hazard a guess that you don't have a table named products. Check the
spelling, capitalization, whether it's the plural "products" or the
singular "product." What helps me say this is that the INSERT statement
above your line 52 inserts into a table called "JShistbau" and your SELECT
statement appears to pull data from a table called "products." I'm not
saying that that's necessarily wrong, because it could very well be
perfectly valid. But without knowing more about your database layout,
that's all I can think of.
By the way, (and it shouldn't matter...) but have you also tried removing
the space in the "end if;" (part of your larger if:-else:-endif;
statement)? I personally don't use that alternative syntax, so I don't
know if the space matters.

Re: [PHP-DB] help with a parse error
Gee...all I looked at were the semicolons and the braces (those are what I
mess up on the most).
I guess it's a good thing I mentioned the space in the endif! It turns out
that if you use that syntax, you cannot have a space there.

I just subsribed to this list with the hope you can help me.
We can try
snip
echo("P Here are all the products in our database: /P:);
add a " before the ; here
// Request the text of all the products
$result = mysql_query(
"select * from products"); !this is
line 52!!
Your problem is the previous line, you are missing a " on the end of it
Cheers

Re: [PHP-DB] simple sql question
There is no date that was before Jan 4th and on or after March 1st simultaneously--not even March 27th. Today might be a special day to individuals for varying reasons (birthdays, anniversaries, new jobs, promotions, whatever) but it's not THAT special that it simultaneously exists in two mutually exclusive sets of dates. http://www.mysql.com/documentation/mysql/bychapter/manual_Reference.html#DAT ETIME How about "...WHERE startDate = '2001-03-01' AND startDate '2001-04-01'" to pull out all of the March events?

Hi,
I am using mysql-3.22.32 with php4.
I have a little problem with the uppercase.
I wanted to display a user input field in CAPS.
This is what I did and it did not work.
$userfield = upper('$userfield');
echo "User Field - $userfield";
Errors (tried both ucase and upper)
Call to undefined function: upper()
Call to undefined function: ucase()
Really appreciate any help that I can get.

Re: [PHP-DB] case insensitive search
You could use the UPPER function. Fortunately you're using PostgreSQL,
which conforms with much of the ANSI standard. UPPER and LOWER are
implementations of the fold functions required by ANSI SQL. This would be
the most standard way to solve your problem (with the notable exception of
support for this on MySQL, don't get me started on how brain dead MySQL is
about string comparisons...though it is a tiny little bit better with its
glaringly non-standard BINARY keyword).
You could alternatively use the much older ~* syntax that PostgreSQL
inherited from its ancestors. But that's completely non-standard, and
there's only one reason to use it since PostgreSQL has the UPPER function
and a LIKE predicate that very closely conforms to the ANSI SQL standard.
That reason is if you want to use regex-like pattern specifiers instead of
SQL-like pattern specifiers.
If you're running a brand-spanking-new 7.1 (beta), you could use the
popular (but non-standard, as far as I can tell--at least I couldn't find
any mention of it in ANSI SQL '92 and I haven't looked at '99 yet) ILIKE.
(Actually, '92 gives ILIKE reserved word status, but does not specify
anything else for it.)
To sum it up, try these:
... WHERE UPPER(blah) LIKE UPPER('%blah%')
... WHERE blah ~* '*blah*' (Note the regex-like pattern specifiers)
... WHERE blah ILIKE '%blah%' (Only on the next version)

im trying to do a case insensitive search in pgsql with a "WHERE blah
LIKE '%blah%'"
the problem is that currently if something contains Blah not just blah
it wont return that. suggestion? i know i can suck out every row and
then eregi them but that is majorly slow and inefficent . . .
