  • Constructor Details

    • HsqlDbBuilder

      public HsqlDbBuilder(Platform platform)
      Creates a new builder instance.
      Parameters:
      platform - The plaftform this builder belongs to
  • Method Details

    • dropTable

      public void dropTable(Table table) throws IOException
      Outputs the DDL to drop the table. Note that this method does not drop foreign keys to this table. Use SqlBuilder.dropTable(Database, Table) if you want that.
      Overrides:
      dropTable in class SqlBuilder
      Parameters:
      table - The table to drop
      Throws:
      IOException
    • getSelectLastIdentityValues

      public String getSelectLastIdentityValues(Table table)
      Generates the SQL for querying the id that was created in the last insertion operation. This is obviously only useful for pk fields that are auto-incrementing. A database that does not support this, will return null.
      Overrides:
      getSelectLastIdentityValues in class SqlBuilder
      Parameters:
      table - The table
      Returns:
      The sql, or null if the database does not support this
    • processTableStructureChanges

      protected void processTableStructureChanges(Database currentModel, Database desiredModel, Table sourceTable, Table targetTable, Map parameters, List changes) throws IOException
      Allows database-specific implementations to handle changes in a database specific manner. Any handled change should be applied to the given current model (which is a copy of the real original model) and be removed from the list of changes.
      In the default implementation, all AddPrimaryKeyChange changes are applied via an ALTER TABLE ADD CONSTRAINT statement.
      Overrides:
      processTableStructureChanges in class SqlBuilder
      Parameters:
      currentModel - The current database schema
      desiredModel - The desired database schema
      sourceTable - The original table
      targetTable - The desired table
      parameters - The creation parameters for the table
      changes - The change objects for the target table
      Throws:
      IOException
    • processChange

      protected void processChange(Database currentModel, Database desiredModel, AddColumnChange change) throws IOException
      Processes the addition of a column to a table.
      Parameters:
      currentModel - The current database schema
      desiredModel - The desired database schema
      change - The change object
      Throws:
      IOException
    • processChange

      protected void processChange(Database currentModel, Database desiredModel, RemoveColumnChange change) throws IOException
      Processes the removal of a column from a table.
      Parameters:
      currentModel - The current database schema
      desiredModel - The desired database schema
      change - The change object
      Throws:
      IOException
