# ConnectionString

The connection string to use to connect to a SQL database that you want Controller to use to store statistics.

This parameter applies only if you set UseODBCDatabase to `True`.

The database must already exist in the SQL backend, but Controller creates any required tables after it connects.

TIP: You can encrypt the value of this parameter by using the autpassword command line tool. For more information about how to use this tool, refer to the IDOL Server Administration Guide.
