On a server running Microsoft Data Access Components (MDAC) 2.5 and SQL Server 7.0 Service Pack 2 (SP2), I'm receiving the ODBC error message Error 24000: Invalid Cursor State. What does this error message mean?

Invalid Cursor State is a bit of a catchall error message. It appears when a configuration problem exists with the client-side MDAC stack (i.e., when one application requires version X of a .dll file and another version requires version Y, causing the installation for either to delete the other version); when your application makes an ODBC call while results from the previous statement are still processing; or when you try to issue multiple statements across one connection. SQL Server doesn't support using one connection to run three concurrent queries that return result sets.
