Hi, can operators be used in MySQL e.g.
a table Table X with column A, column B column C All three are floats can I use select (A-B) from X where <condition> or will I have to so the A-B calculation in my application code instead? Also can I use select C from X where <condition> Then update X set C = (return values got from above + New Increment) where <condition> Any help would be greatly appreciated many thanks Joe
