Is MySQL Case Sensitive

I have a mysql 5.0 database running on an Windows XP Machine. The database contains around 50 stored procedures. I want to migrate the database to a machine which is running on linux. The migration happens smoothly. Whenever I call the stored procedure from my application it gives me an error. For example if I had declared a variable myint then when i try to use it as MYINT the stored procedure gives me an error. Is there any work around for this problem. This problem never occured when the database was running on a windows machine

Maybe try this:
