Its possible with MyODBC Drivers to 'n' size. You can supply BLOB/CLOB data in pieces to desired size by making use of SQLParamData and SQLPutData APIs. Here is a simple examples using 'C-ODBC'. 1. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/odbc/htm/odbc sending_long_data.asp 2. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/odbc/htm/odbc sqlputdata.asp I think it should also be possible with MmDriver, but never tested.
