Class SetConstraintsConstantAction

java.lang.Object

org.apache.derby.impl.sql.execute.DDLConstantAction

org.apache.derby.impl.sql.execute.SetConstraintsConstantAction

All Implemented Interfaces:

ConstantAction

class SetConstraintsConstantAction
extends DDLConstantAction

This class describes actions that are performed for a set constraint at execution time.

Note that the dependency action we send is SET_CONSTRAINTS rather than ALTER_TABLE. We do this because we want to distinguish SET_CONSTRAINTS from ALTER_TABLE for error messages.
