Constructor Detail

DropTriggerConstantAction

DropTriggerConstantAction(org.apache.derby.iapi.sql.dictionary.SchemaDescriptor sd,
                          java.lang.String triggerName,
                          org.apache.derby.catalog.UUID tableId)

Make the ConstantAction for a DROP TRIGGER statement.

Method Detail

executeConstantAction

public void executeConstantAction(org.apache.derby.iapi.sql.Activation activation)
                           throws org.apache.derby.iapi.error.StandardException

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

dropTriggerDescriptor

static void dropTriggerDescriptor(org.apache.derby.iapi.sql.conn.LanguageConnectionContext lcc,
                                  org.apache.derby.iapi.sql.depend.DependencyManager dm,
                                  org.apache.derby.iapi.sql.dictionary.DataDictionary dd,
                                  org.apache.derby.iapi.store.access.TransactionController tc,
                                  org.apache.derby.iapi.sql.dictionary.TriggerDescriptor triggerd,
                                  org.apache.derby.iapi.sql.Activation activation)
                           throws org.apache.derby.iapi.error.StandardException

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

modifiesTableId

public boolean modifiesTableId(org.apache.derby.catalog.UUID tableId)

Does this constant action modify the passed in table uuid? By modify we mean add or drop things tied to this table (e.g. index, trigger, constraint). Things like views or spses that reference this table don't count.

Specified by:

modifiesTableId in interface org.apache.derby.iapi.sql.execute.ConstantAction

Overrides:

modifiesTableId in class DDLConstantAction
