I have installed WampServer 2.0 with MySQL 5.1.33.
I can do Numeric and String functions like
SELECT ABS(-2)
orSELECT LOWER(\'ASD\'
Many functions are different in SQlite and in MySQL (or any other product - if you except core functions, most functions provide the same functionality but with a different syntax). There is an open-source "compatibility library" implementing a large number of MySQL functions in SQLite on the Kansas State University CIS website
