Method Detail

main

public static void main(java.lang.String... a)
                 throws java.lang.Exception

Run just this test.

Parameters:

a - ignored

Throws:

java.lang.Exception

test

public void test()
          throws java.sql.SQLException

Description copied from class: TestBase

This method will be called by the test framework.

Specified by:

test in class TestBase

Throws:

java.sql.SQLException

fire

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

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.

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)

close

public void close()

Description copied from interface: Trigger

This method is called when the database is closed. If the method throws an exception, it will be logged, but closing the database will continue.

Specified by:

close in interface Trigger

remove

public void remove()

Description copied from interface: Trigger

This method is called when the trigger is dropped.

Specified by:

remove in interface Trigger

init

public void init(java.sql.Connection conn,
                 java.lang.String schemaName,
                 java.lang.String trigger,
                 java.lang.String tableName,
                 boolean before,
                 int type)

Description copied from interface: Trigger

This method is called by the database engine once when initializing the trigger. It is called when the trigger is created, as well as when the database is opened.

Specified by:

init in interface Trigger

Parameters:

conn - a connection to the database

schemaName - the name of the schema

trigger - 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
