EDIT: For simple testing of an in-memory database like HSQLDB, a crude approach can be used to automatically create tables: private void createHsqldbTables(IDataSet dataSet, Connection connection) throws DataSetException, SQLException { String[] tableNames

We just want to get the CSV data into the SQL database quickly and extract the relevant
