SQL: format numeric to x decimal places
i found this was very hard to figure out.  i read lots of approaches to hack the data into char(5) etc to give you "23.54" using Round() etc.  but that seemed messy.  the key is to cast to type Numeric(size, decimalPlaces).  for example:
CONVERT(Numeric(10,2), (Count(ID) * 100. / @Total)) as Percentage

the above will display "23.54" (for example), including rounding, as a number.

does not work with MS Access sql ... function CONVERT is not defined.

MS Access does not implement standard T-SQL, it has its own limited variation of SQL.
Good luck

I need to be able to pass an integer which sets the number of decimal places. It doesn't seem to work to use a variable in the NUMERIC declaration...any ideas?
