Alter table failed - non-existent constraint
This message appears when an ALTER TABLE...DROP CONSTRAINT statement references a nonexistent constraint. Constraints can only be dropped by specifying the constraint name. If a constraint was created without a user-defined name, one was routinely generated by the Data Vault Service.
The easiest way to determine the constraint name is to violate the constraint
intentionally
. This will produce an error message that lists the name of the violated constraint.
