        Parameters:
        a - ignored
        Throws:

      • isEnabled

        public boolean isEnabled()
        Overrides:
        isEnabled in class org.h2.test.TestBase
        Returns:
        whether this test is enabled in the current configuration

      • test

        public void test()
          throws java.lang.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:
        java.lang.Exception - if an exception in the test occurs

      • 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

      • 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. 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)
