Can a user connect using 32 bit SQL ODBC driver into SQL Server 64 bit version or do they need to use a 64 bit SQL ODBC driver?
Thanks in advance.

They both can connect to either 32 or 64 bit databases. Use the 32 bit driver when the client application or process is 32 bit.

Just to be clear, the driver 32/64 is a CLIENT side edition. This does not affect in any way connecting to the server.

Hi,

Both 32-bit and 64-bit drivers can connect to 32-bit or 64-bit servers.
