In Direct Mode ODBC Driver for MySQL interacts with MySQL directly via TCP/IP. So you don't need to install any additional software when working with MySQL in Direct Mode.
Below you can see the requirements:
- If you use MySQL Embedded server, you need the server itself (libmysqld.dll) and accompanying files like errmsg.sys.
- If you are working not in Direct Mode, you need the client library (libmysql.dll).
- Important condition is that only one ODBC Driver for MySQL version can be installed on the PC in order to avoid incompatibility.
