You can redefine the delimiter to a string other than //, and the delimiter can consist of a single
character or multiple characters. You should avoid the use of the backslash ("\") character because

18.2. Using Stored Routines (Procedures and Functions)

Stored routines (procedures and functions) are supported in MySQL 5.0. A stored routine is a set of
SQL statements that can be stored in the server. Once this has been done, clients don't need to keep
reissuing the individual statements but can refer to the stored routine instead.
Stored routines require the
5.0 installation procedure. If you are upgrading to MySQL 5.0 from an earlier version, be sure to update
