Question

Is there an easy way to format SQL Server numeric(18,6) data type to format similar to c#’s {0:#.00####} but in T-SQL?

E.g.

1. 12.550000 should produce 12.55.
2. 14.456700 should produce 14.4567.
3. 15.00 should produce 15.00.

As HLGEM says, it’s best to do this kind of stuff on the front end, but for kicks, the following code seems to work. There’s probably a better way to do it though.

REPLACE(
     RTRIM(
          REPLACE(
               CAST(@test AS VARCHAR), '0', ' '
          )
     ), ' ', '0'
) +
CASE
     WHEN @test = FLOOR(@test) THEN '00'
     WHEN FLOOR(@test*10) = @test * 10 THEN '0'
     ELSE ''
END
