DB2 SQL-Error: -634

Short Description: THE DELETE RULE MUST NOT BE CASCADE

The code is used to report that the CASCADE delete rule specified in the FOREIGN KEY clause of an ALTER TABLE statement is invalid because: v The relationship would form a cycle that would cause a table to be delete-connected to itself. v The relationship would cause another table to be delete-connected to the same table through multiple paths with different delete rules or with a delete rule equal to SET NULL.System action: The statement cannot be executed. Programmer response: Change the delete rule.
