I am using pymssql for Python 2.7 with MS SQL Driver. While running some queries on tables having sql_variant column, I am getting bad data. When I cast data, I am able to get correct values. Is there any way I can skip explicit CAST.

and just refering to the last column there.
Although pymssql makes it possible to add some sql when connecting in conn_properties:
Is there any SQL specialist that can answer the following question: is there any simple SQL command that would make the DB handle all sql_variant fields as some pre-defined types for entire session? Something that could be passes as conn_propeties any time a pymssql.connect is called?
