                                       java.lang.String constraintSchemaName,
                                       java.lang.String tableName,
                                       UUID tableId,

                                       int verifyType)

Make one of these puppies.

Parameters:

constraintName - Constraint name.

constraintSchemaName - the schema that constraint lives in.

tableName - Table name.

tableId - UUID of table.

tableSchemaName - the schema that table lives in.

indexAction - IndexConstantAction for constraint (if necessary)

behavior - the drop behavior (e.g. StatementType.DROP_CASCADE)

Method Detail

getIndexConglomerateId

public long getIndexConglomerateId()

Only available after executeConstantAction(Activation), get the conglomerate ID associated with this constraint, or -1 if no index conglomerate is associated.

Returns:

the associated index conglomerate ID for this constraint, or -1 if no index is associated.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

executeConstantAction

public void executeConstantAction(Activation activation)
                           throws StandardException

This is the guts of the Execution-time logic for DROP CONSTRAINT.

Parameters:

activation - The execution environment for this constant action.

Throws:

StandardException - Thrown on failure

getScopeName

public java.lang.String getScopeName()

Specified by:

getScopeName in interface ScopeNamed

Overrides:

getScopeName in class DDLConstantOperation
