i have line in query: case when count(n.counter) <> 0 (cast(count(n.counter) float)/count(t.counter)) * 100 else 0 end percent i'm getting results 79.565974946. want result 80% (with no digits after decimal point , '%' sign). how can that? you need round , then, because you're trying formatting, convert string before adding % : convert(varchar(20), round( case when count(n.counter) <> 0 (cast(count(n.counter) float)/count(t.counter)) * 100 else 0 end ,0)) + '%' percent also, there may typo here - looks you're trying avoid divide 0 error, you're testing wrong operand ( n.counter rather t.counter ) may still division 0 code.
