PHP5 Code works in mysql 4.1.7 but not in mysql 5.0.18

Hi,

I am working on a Test Server to transition our pages from mysql 4.1.7 to v. 5.0.18. I am using the same install of PHP5.1.2 to access the databases by changing the port designation depending on the version of mySQL I wish to access.

I can login to both versions of mySQL both through command line and MySQL Administrator. I am also able to create a connection to both databases without error through a PHP page using mysqli_connect.

My problem:
A query I make in 4.1 returns results while the identical query in 5.0 doesn't return results. I echo the query string to the page and am able to return results if I copy the 5.0 string into Query Browser.

$result=mysqli_query($mysqli, $SqlStr); is what I am using for the query request.

Select owners.ownerid from owners Where Owners.Active = 1 And lname like "White%" AND fname like "Michael%".

I do have the mysqli lines in php.ini uncommented, am using the suggested dll's from mysql for the connection, all errors set in php.ini and am running this on a Win2003 server.

Any suggestions would be greatly appreciated,

Michael
