  • Method Details

    • main

      public static void main(String... a) throws Exception
      Run just this test.
      Parameters:
      a - ignored
      Throws:
      Exception

    • test

      public void test() throws Exception
      Description copied from class: org.h2.test.TestBase
      This method will be called by the test framework.
      Specified by:
      test in class org.h2.test.TestBase
      Throws:
      Exception - if an exception in the test occurs

    • fire

      public void fire(Connection conn, Object[] oldRow, Object[] newRow) 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

    • 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(Connection conn, String schemaName, String trigger, 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. The type of operation is a bit field with the appropriate flags set. As an example, if the trigger is of type INSERT and UPDATE, then the parameter type is set to (INSERT | UPDATE).
      Specified by:
      init in interface Trigger
      Parameters:
      conn - a connection to the database (a system connection)
      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, DELETE, SELECT, or a combination (this parameter is a bit field)
