- DELETE, INSERT, SELECT, UPDATE
- The SQL operations that can be enforced by a constraint.
- You must specify between 1 and 4 SQL operations per constraint definition. Each specified SQL operation must be followed by the SYSLIB.function_name that enforces the operation.
- You cannot specify an SQL operation type more than once in a constraint.
- The name of the UDF that enforces the corresponding DELETE, INSERT, SELECT, or UPDATE operation for the constraint.
- The specified UDF must be contained within the SYSLIB database at the time you specify it in the constraint definition.
- Each UDF named in SYSLIB.function_name specifications for a constraint defines the minimum classification required to perform the associated SQL operation on each row of a table that includes the constraint.
