>What Iam trying to do is to create a sql string for ADO. I know that technique but it looks too complex for that. Plus I need to add some parameters for ADO query.

I disagree. Not "too complex". And AFAIK there is no other way to avoid "String too long" error. Native Fox SQL or ADO - it doesn't matter. You should produce the long string from the smaller ones. If you deal with really large SQL statement it will be comfortable for you as well - to review small parts of your statement, won't it?
