[SSIS 2012] ODBC Destination Batch Size

Hello,

I'm trying to use ODBC destination with SQL Server Native Client 11.0 and a 1000 batch size, but ODBC still write Row By Row on the DB.

MSDN said that :

Batch: In this mode the ODBC destination attempts to use the most efficient insertion method based on the perceived ODBC provider capabilities. For most modern ODBC providers, this would mean preparing an INSERT statement with parameters and then using a row-wise array parameter binding (where the array size is controlled by the BatchSize property). If you select Batch and the provider does not support this method, the ODBC destination automatically switches to the Row-by-row mode.

But SQL Server Native 11.0 should be able to write in batch mode isn't it ?

Any idea of the reason why my ODBC destination in SQL Server 2012 with SSIS 2012 still making row by row instead of batch ?

Regards
