      • 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.

        The row arrays contain all columns of the table, in the same order as defined in the table.

        The trigger itself may change the data in the newRow array.

        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
