C ++ operate MYSQL to check whether the database to be created exists
If the database already exists, do not create a database and disconnect it.
How can this be implemented?

The method I used previously was to delete the database and try to improve it if there is a database.
Char str [] = "drop database if xx exists"
Ret = mysql_real_quary (& mysql, str, sizeof (str)-1)
