return value from stored procedure

I have a stored procedure like this:

Select @totalMoney*@bonusPercent/100 

How i can return value from procedure and assign it to the开发者_运维知识库 varible? i mean something like:

SET @myVarible = EXEC MyStoredProcedure @param1, @param1;

---

Use an output variable, return only works with integers

example

create procedure prTest @id int, @id2 decimal(20,10) output
as
select @id2 = @id + 1
go

now call it like this

declare @Test decimal(20,10)


exec prTest 5,@Test output
select @Test

output
6.00000000

---

Within the stored procedure just use

 RETURN @X

@X must be an integer data type.

Return codes are normally used for status codes though. An output parameter may be a better choice dependant upon what you are doing exactly.

Declare the parameter as OUTPUT

CREATE PROCEDURE dbo.MyStoredProcedure 
@param1 INT,
@myVarible DECIMAL(10,4) OUTPUT
AS 
...

and call it as

EXEC dbo.MyStoredProcedure @param1, @myVarible OUTPUT;
