RE: [PHP-DB] PHP4, mssql_* and SQL Server 2005
Follow up- We solved this by moving that hugemongous query into a stored procedure. Not the most elegant fix but until we get to PHP5 and native driver, etc it seems our only fix. -Original Message- From: Krister Karlström [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 05, 2008 2:04 PM To: Weaver Hickerson Cc: PHP DB Subject: Re: [PHP-DB] PHP4, mssql_* and SQL Server 2005 Ouch! That was like the.. longest.. query that I've ever seen! I'm surprised that it actually works and even more impressed that someone actually figured that out... It might take a long time to run, since it uses so many subqueries (if there's lots of data or even a moderate amount of data). Are you sure there's no easier way to fetch your data? Most subqueries can be re-written using a join and some more where-comparisons instead... Actually I'm more amazed that you actually can send that query and that it works.. There's a slight chance that your problems might be solved by rewriting that query... Maybe it's just to long or something, I don't know. I will however not take the time to refactor that query... :) Are you running PHP under Linux or Windows? You said that you only found two queries that breaks? Wll, if the shorter ones works, but the longer ones hangs, then maybe that's the problem...? :) Regards, Krister Karlström, Helsinki, Finland Weaver Hickerson wrote: Krister - I've included the query below - If I paste it in query analyzer on 2000, or 2005 it works fine.

Re: [PHP-DB] PHP4, mssql_* and SQL Server 2005
Hi!
Have you checked that the query is escaped correctly? All single quotes
(') needs to be escaped with another single quote, but that has been for
MS-SQL all the time so I'll doubt that the problem is escaping.
Another issue I noticed is that SQL Server 2005 handles SMALLDATETIME
coulmns slightly different, and the default formatting of the retuned
date is in some collations different than in SQL Server 2000. So if you
have any queries relying on a where clause that checks a SMALLDATETIME
column you might need to adjust the date format.
Migrating to SQL 2005 might also cause some problems with character
encoding, since SQL 2005 internally works with Unicode. At least for us
who needs other characters than 7-bit ASCII... I had big trouble with
moving ISO-8859-15 XML documents to a SQL Server 2005 Unicode server and
parsing them into a native XML datatype (which is a really nice
feature!), but the problems can be overcomed with a litte extra work...
You could also check that you use the correct protocol version of
FreeTDS, if you're running PHP under Linux. I don't know how PHP
connects to MS-SQL on Windows though.
Currently I have no other thoughts of what could cause your problems, at
least without not being able to actually see the failed queries.

the code to that driver. :(
That does seem to point to the driver, not sure what other suggestions I
can offer.

[PHP-DB] PHP4, mssql_* and SQL Server 2005
Greetings to the group. We have a PHP4 application that we moved to SQL server 2005 from SQL server 2000. Everything seems to work fine except for so far we have found 2 queries that break. Pointing back to the SQL Server 2000 server, they work fine again. Closing the gate once the horse is out, I then began googling and it appears that there is some controversy over whether PHP4 works with SQL 2005? So far everything but this works so I'm wondering if there are some php INI settings and/or SQL Server settings that might make the 2 get along better.. Any help appreciated in resolving this without having to do an overnight forklift port to PHP5 (would that it be that easy..)

If it's only 2 queries I suspect that sql server 2005 breaks for those queries (whether they added new reserved words or whatever). If you run those 2 queries manually through the db, what happens? -- Postgresql php tutorials http://www.designmagick.com/ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
