Hi Bob,

Yes, that is what i'm aiming at, but i'm thinking of how to do it fast.

Explanation:

I can read 1000 records to the hostarray. I want to find the dupes before inserting into the table. The hostarray may contain records that are in the table. I would like a select statement returning a status for each record in the hostarray, e.g. 0 if it's not a dupe, and 1 if it is. Then i would know which records to ignore, and which to insert.

Do you think this is possible?

Best regards,
Brian
