Creating Tables With a Table Creator

After creating a TableCreator class (see "Creating a Table Creator"), you can use its API to create and drop tables. The important TableCreator methods are as follows (each method takes an instance of DatabaseSession):

• createTables–this method creates tables, adds constraints, and creates sequence tables and sequences (if sequence tables already exist, this method drops them and recreates them).

• dropTables–his method drops all constraints and drops all tables (except sequence tables) that the TableCreator defines.

• createConstraints–this method creates constraints on all pre-existing tables that the TableCreator defines.

• dropConstraints–this method drops constraints on all pre-existing tables that the TableCreator defines.

• replaceTables–this method drops and then creates all tables that the TableCreator defines.
