init

public void init(java.sql.Connection conn,
                 java.lang.String schemaName,
                 java.lang.String triggerName,

Description copied from interface: Trigger

This method is called by the database engine once when initializing the trigger.

Specified by:

init in interface Trigger

Parameters:

conn - a connection to the database

schemaName - the name of the schema

triggerName - the name of the trigger used in the CREATE TRIGGER statement

tableName - the name of the table

before - whether the fire method is called before or after the operation is performed

type - the operation type: INSERT, UPDATE, or DELETE

Throws:

fire

public void fire(java.sql.Connection conn,
                 java.lang.Object[] oldRow,
                 java.lang.Object[] newRow)
          throws java.sql.SQLException

Description copied from interface: Trigger

This method is called for each triggered action. The method is called immediately when the operation occurred (before it is committed). A transaction rollback will also rollback the operations that were done within the trigger, if the operations occurred within the same database. If the trigger changes state outside the database, a rollback trigger should be used.

Specified by:

fire in interface Trigger

Parameters:

conn - a connection to the database

oldRow - the old row, or null if no old row is available (for INSERT)

newRow - the new row, or null if no new row is available (for DELETE)

Throws:

java.sql.SQLException - if the operation must be undone
