Using ODBC Data Sources To Connect To Microsoft SQL Express 2019 Remote Server

ODBC Data Sources is a interface that allows users to access data in any database that has an ODBC driver. There are two versions of ODBC in your computer; 32-bit and 64-bit. Depending on the version that you wish to use, you will need to download the same version of ODBC driver. Using a 32-bit ODBC driver will not work with ODBC 64-bit. Both versions are located in different locations as mentioned below.

ODBC 32-bit:


ODBC 64-bit:
