Description:
------------
I am actually using PHP 5.1.4, theres no option for that in the list.
Whenever I try to do a PDO->query, false is returned even if rows should have been returned (I've checked and re-checked the SQL against a table to absolutely ensure that data should be returned).
I have classes that use PDO's that worked perfectly right before I upgraded to MySQL 5.
I've recompiled PHP and double checked everything I can, but I can not figure out this issue and Google hasn't been any help so my best guess is either my configuration is out of wack (which I'm 99% sure it's fine) or I've stumbled across a bug.

I'll be honest I was surprised your code worked for me because I thought you had to call fetch() to get at the data, but I had no problems with it. Have you tried using fetch()? something like: $result = $db->query("SELECT * FROM FOO"); while( $row = $result->fetch(PDO::FETCH_ASSOC) ){ print_r($row); } just a thought.I'm running Fedora Core 5 with PHP 5.1.4 - trying to get pdf_informix to retrieve a simple row of data from 1 table and hit the same issue! This works... foreach ($dbh->query('select * from case where cs_caseid = 258579'); But this doesn't: foreach ($dbh->query('select * from case where cs_caseid = 258588'); I've verified record existance in the table. This should work - such a simple query. Any ideas? (apart from maybe a buggy PHP version 5.1.4?)I'm experiencing the same trouble on PHP 5.2.0 (final). My query is very simple: $stmt = $conn->query('SELECT * FROM articles'); And it returns false, table exists and has rows in it, and connections is ok. I have no troubles with regular mysql extension. I'm using PHP 5.2.0 on Windows + PDO + PDO_MYSQL.
