Issues Parsing Multiple Result Sets

[david-engelmann]

the cursor object description is not updated when cursor.nextset is called. I'll need to dive deeper to see where the issue occurs. The problem is that when parsing multiple result sets you can't tell which set you are looking at

Relevant Documentation of SQLMoreResults

I believe the most relevant section is as follows:

When SQLMoreResults returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, an associated SQLSTATE value can be obtained by calling SQLGetDiagRec with a HandleType of SQL_HANDLE_STMT and a Handle of StatementHandle.
