Examples of org.apache.metamodel.UpdateableDataContext.executeUpdate()

org.apache.metamodel.UpdateableDataContext.executeUpdate()
Submits an {@link UpdateScript} for execution on the {@link DataContext}. Since implementations of the {@link DataContext} vary quite a lot, thereis no golden rule as to how an update script will be executed. But the implementors should strive towards handling an {@link UpdateScript} as asingle transactional change to the data store. @param update the update script to execute


    final List<Object[]> values = source.getValues();


    assertEquals(3, values.size());


    intercepted.executeUpdate(new UpdateScript() {
      @Override
      public void run(UpdateCallback callback) {
        callback.insertInto("schema.table").value(0, 1).value(1, "2")
            .execute();
        callback.insertInto("schema.table").value(0, 3).value(1, "4")
