Do minus sign in mysql table column names cause issues?


Do minus sign in table column names effect performance or cause issues on some platforms or it is allowed or not?

Enclose the names within back-ticks

CREATE TABLE `my-table` ( `user-Id` int(11) NOT NULL, `url` varchar(100) NOT NULL, `epoch` int(11) NOT NULL );
