SQL Query with LIKE

[syscol]

Hello,

I have a problem with my development :

I develop a intern WEB Site in ASP for a company that use a FileMaker Database.

I have setting up a System DSN on the server, the database is open on my computer.

I have no problem when I use a SQL query like

SELECT * FROM DB WHERE Fieldx = 'toto'

The problem is when i do the following query :

SELECT * FROM DB WHERE Fieldx LIKE '%toto%'

I receveid a timeout and my computer is 100% occuped by the Filemaker Pro 5 process for 1 or 2 minutes.

Can someone help me ?
