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.
