It includes these enhancements and fixes: Driver Compatibility -------------------- MS SQL Server MS SQL Server Native Client * Added a fix for the MS SQL Server Native Client error "[Microsoft][ODBC Driver 11 for SQL Server][SQL Server]The data types varchar and text are incompatible in the equal to operator." when trying to bind a string of more than 256 bytes to a *VARCHAR* column while using cursor.executedirect(). cursor.execute() was unaffected by this. Thanks to Paul Perez for reporting this. * Added a note to *avoid using "execute "* when calling stored procedures with MS SQL Server. This can result in '[Microsoft][SQL Native Client]Invalid Descriptor Index' errors. Simply dropping the "execute " will have the error go away. FreeTDS ODBC Driver * Added a work-around to address the FreeTDS driver error '[FreeTDS][SQL Server]The data types varbinary and image are incompatible in the equal to operator.' when trying to bind binary strings longer than 256 bytes to a *VARBINARY* column. This problem does not occur with the MS SQL Server Native Client. * Reenabled returning *cursor.rowcount* for FreeTDS >= 0.91. In previous versions, FreeTDS could return wrong data for .rowcount when using SELECTs.This should make *SQLAlchemy* users happy again. * Add work-around to have FreeTDS ODBC driver accept *binary data* in strings as input for VARBINARY columns. A side effect of this is that FreeTDS will now also accept binary data in VARCHAR columns. SAP Sybase ASE * Added work-arounds and improvements for Sybase ASE ODBC drivers to enable working with *BINARY* and *VARBINARY* columns. * Added a work-around for a *cursor.rowcount* problem with Sybase ASE's ODBC driver on 64-bit platforms. It sometimes returns 4294967295 instead of -1. * Added note about random segfault problems with the *Sybase ASE 15.7 ODBC driver* on Windows. Unfortunately, there's nothing much we can do about this, other than recommend using the Sybase ASE 15.5 ODBC driver version which does not have these stability problems. Misc: * Added improved documentation on the *direct execution model* available in mxODBC. This can help in more complex parameter binding situations and also provides performance boosts for a few databases, including e.g. MS SQL Server. * Improved tests and added more data binding tests, esp. for SELECT queries with bound parameters. * Fixed some minor issues with the *package web installer* related to Linux2 vs. Linux3, FreeBSD installations and an intermittent error related to hash seeds, which sometimes caused prebuilt archives to not install correctly.
