Jay,

Two possibilities:

1. Before you add the constraint, issue a Select query with the Where clause being the NOT version of your Check Constraint. This is the least hassle.
2. Use the Exceptions Into clause when you create the Check Constraint. This will populate an Exceptions table with the RowIDs of the rows that violate the Check. See the Constraint_Clause section of the SQL Reference for details.

When a check constraint is added to a table, is there an option in Oracle that will display or list the rows in the table that violate the constraint? TIA. Jay
