simply be 1,2,3,4 or 5. tinyInt obviously works fine for this, BUT:
I want to do something like 'SELECT AVG(ratings) as avgRating' And this
always returns an tinyint datatype since the ratings are tinyints. I want
slightly more precision than a tinyint for the average, what I want is
something in the format of '#.##' (i.e. 3.45). What datatypes do I need to
store the ratings in and what command can I use to get JUST a #.##?
I've changed the datatypes to money and decimal and used the ROUND function,
but it still returns something like '3.4500'.
Any help is appreciated, thanks in advance
