Possible VARCHAR issue, possible collation issue? Help!!

Posted by Andy on 05/27/07 20:59

Hi,

I hope someone can help me with the issue I am experiencing.

If it's relevant I'm Running Apache 2.0.58 on windows XP, PHP 5.1.4 and
MySQL 5.0.22...not up to date I know but fairly current and more than
adequate for my testing server.

The problem I am experiencing is probably down to my inexperience with MySQL
but I would appreciate some guidance with this.

I have created several HTML forms to query my MySQL database using PHP, all
is good except for one field which does not return the values expected. The
field in the table is set as VARCHAR(20) since it needs to store part
numbers and these are in the format AA100-ZZ9999 (with some exceptions which
start with 3 alpha characters followed by 6 numeric). When I search for 100
I get no results but when I search for AA the correct results are returned.
The Collation is ascii_bin is this the problem??

Also is there a way of making PHP forms acting on a MySQL database not case
specific?

I hope someone can help me.

Thanks in advance.



Regards,

Andy.
