My case appears to be pretty common, i.e. 1 small and 1 large table with RI constraint between them. In order to delete a record from the small table, the large table must not have records that are dependent on the deleted row. I think other RDBMSs simply use preset value instead of partial table scan when there's not enough stat info. Might be a better way. Thanks __________________________________ Do you Yahoo!? Yahoo!
