Comments - SET Variable statement

Apparently it was only meant to demonstrate what SET statement looks like, but yes, it was a particularly unfortunate example. I have fixed it now, thanks for noticing.

you wouldn't happen to know the correct syntax for the following:

SET @dbname = 'name'; drop database if exists @dname;

First line works but second doesn't know what @dbname is.

You need prepared statements to pull it off. Something like

SET @dbname = 'name';
SET @sql = CONCAT('drop database if exists ', @dbname);
PREPARE stmt FROM @sql;
