I would like to have a function given a user id varchar(64) to get a hash number between 0 and 255. I first tried md5 but the number it returns is very big and cannot be converted to an INT there is likely a way to simply add ascii values of the userId together to get a small integer, but wanted to know if there are any other 'built-in' ways this is to get the database id based on user id.
maybe take the last byte (2 chars) of the md5, and convert to integer? something like....
