Description: ------------ After I mentioned in the file example4/demodata.xml (for demodata.php) line from 1647 following the change made <field> <name>news</name> <type>clob</type> </field> Now it works with my local mysql database without problems. Only if I try mssql comes with the following error message I could not populate the database, see error below MDB2_Schema Error: unknown error Could not end transaction (MDB2 Error: unknown error (_doQuery: [Error message: Could not execute statement] [Last executed query: COMMIT TRANSACTION] [Native code: 3902] [Native message: Die COMMIT TRANSACTION-Anforderung hat keine entsprechende BEGIN TRANSACTION.] ))

no clue what the error message means. maybe MSSQL doesnt support transactions and the driver tells the oposite ?

The error message says: The COMMIT TRANSACTION query has no corresponding BEGIN TRANSACTION. SQL Server does support transactions. Can you send me the query log?

please pass the following array to MDB2_Schema factory: $options = array( 'disable_query' => false, 'debug' => 'false', 'debug_handler' => 'printQueries', 'parser' => 'MDB2_Schema_Parser', 'quote_identifier' => true, 'log_line_break' => '<br>', 'use_transactions' => false ); that should disable transactions. please tell me if that fix your problem.
