Significance of /*!32312 IF NOT EXISTS*/;

[Todd Cary]

In my mysql dump of a DB using the -B switch, I get

CREATE DATABASE /*!32312 IF NOT EXISTS*/ sfyc;

What is the significance of /*!32312 IF NOT EXISTS*/ - the "/*!32312"?  Isn't
the statement commented out?

With the CREATE TABLE, what happens if the table already exists?

Todd
