Hi Everyone,

here is a simple SP

Create procedure test
@input float
as
Begin
return @input
ENd

If I execute the following
declare @output float
exec @output=test 1.12121
select @output

why I got 1 not 1.12121?

any idea? How to get the correct result?

Thank you in advance

Because RETURN only returns integers. You must use an output variable instead.

Create procedure test
(@input float, @output float OUTPUT)
as
Begin
SET @output = @input
ENd
go

declare @output float
exec test @input = 1.12121, @output = @output OUTPUT
select @output

drop proc test
