Method Detail

fire

public void fire(java.sql.Connection conn,
                 java.sql.ResultSet oldRow,
                 java.sql.ResultSet newRow)
          throws java.sql.SQLException

Description copied from class: TriggerAdapter

This method is called for each triggered action by the default fire(Connection conn, Object[] oldRow, Object[] newRow) method. ResultSet.next does not need to be called (and calling it has no effect; it will always return true).

For "before" triggers, the new values of the new row may be changed using the ResultSet.updateX methods.

Specified by:

fire in class TriggerAdapter

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
