public void fire(Connection conn,

          throws 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:

SQLException - if the operation must be undone
