I want to select a bunch of items and insert them somewhere else. If
the insert fails because of a duplicate primary key or unique
constraint, I want to abandon that particular item and continue with the
rest.
This code outlines my logic. Is this correct for what I'm trying to
accomplish?

BEGIN

FOR SELECT DO BEGIN

BEGIN

INSERT

END /* INSERT */

WHEN GDSCODE unique_key_violation DO
BEGIN
/* NOP */
END

END /* SELECT */

END /* PROCEDURE */
