Hello, I want to connect sql in a script, how to do it?
I use this 

Core.MySql.Libraries.MySql sqlLibrary = Interface.Oxide.GetLibrary<Core.MySql.Libraries.MySql>();
Connection sqlConnection = sqlLibrary.OpenDb("localhost", 3306, "umod", "username", "password", this);​

Are you missing `Oxide.Core.Database' or `Oxide.Ext.MySql' or `CompanionServer' or `Network' or `Steamworks.Data' or `Oxide.Ext.SQLite' using directive?

I add this using Oxide.Ext.MySql

and the error again

Wulf, you have example sql use?

Figured out, but there is a problem with checking.  not work this if(list == null)puts('OK')
