Question

I got a Syntax Error around that double , is there something wrong ? Is that safe to switch to float , but works ?

create proc S_average
(
    @dept_id char(10),
    @dept_name char(10) OUTPUT,
    @dept_avg double OUTPUT
)
AS
select @dept_name = name , @dept_avg = payroll
from dbo.employees
where id = @dept_id;

Thanks !

There is no double datatype in SQL Server. You should be using float in place of that (or real in earlier versions, but you don’t have a SQL Server version posted).

float doesn’t have quite the same precision as double in C# (again, I’m assuming a .NET language as it isn’t posted) if you are looking to pass values to the application. But float is the closest to C#’s double and almost definitely going to be perfect for your requirement.
