CREATE DATABASE with variable name

[Fabricio Rodriguez]

I'm trying to create a routine in MySQL Workbench which creates a database with whichever name I pass it in a parameter. So:

DELIMITER $$

CREATE PROCEDURE `db1`.`create_database` (databaseName varchar(45))
BEGIN
CREATE DATABASE databaseName;
END

The problem is that if I run this routine, it will create a database named "databaseName", and not the name that I pass it in the databaseName parameter. Anyone know how to get around this? Thank you...
