Interesting option. You mean like re-nice-ing mysqld on the host (Linux)
level?
Has anyone upgraded MySQL 4.0 to 5.0 on a Mac running Mac OS X

What you need is Dynamic SQL via the PREPARE statement
Like This :
CREATE PROCEDURE `myDB`.`sp_test` (myTable varchar(20))
BEGIN
DECLARE SQLCommand VARCHAR(1024);
SET SQLCommand = CONCAT('SELECT * FROM ',myTable);
SET @SQLStmt = SQLCommand;
PREPARE s1 FROM @SQLStmt;
EXECUTE s1;

points you should keep in mind:
-
SQL Server doesn't support the IF EXISTS clause.
There are also differences in data types.
