The back end is some proprietary database. It's basically an unknown since we know almost nothing about it and have very little documentation on it. The database is for a product called Global Shop. They claim it is some sort of COBOL database?

At any rate the tables we're unfiltered until yesterday when I tried to add a filter on one of our SELECT statements in one of the SQLEXEC()'s. I thought if I put in a simple filter it may reduce the resultant cursor size and hopefully speed things up.

They are testing today...

Thanks again,
Don
