请查看下面的示例，通过执行存储过程获得输出变量值。

    DECLARE @return_value int,
    @Ouput1 int,
    @Ouput2 int,
    @Ouput3 int

EXEC    @return_value = 'Your Sp Name'
        @Param1 = value1,
        @Ouput1 = @Ouput1 OUTPUT,
        @Ouput2 = @Ouput2 OUTPUT,
        @Ouput3 = @Ouput3 OUTPUT

SELECT  @Ouput1 as N'@Ouput1',
        @Ouput2 as N'@Ouput2',
        @Ouput3 as N'@Ouput3'

下面是stored_proc的定义:

create proc product(@a int,@b int)
as
return @a * @b

这是从Python中执行的: Conn = pyodbc.connect('…') Cursor = conn.cursor()

sql = """
SET NOCOUNT ON
declare @r float
exec @r=dbo.product 5,4
select @r
"""
result = cursor.execute(sql)
print (result.fetchall())

试试这个;对于多个输出参数，它工作得很好:

CREATE PROCEDURE [endicia].[credentialLookup]
@accountNumber varchar(20),
@login varchar(20) output,
@password varchar(50) output
AS
BEGIN
SET NOCOUNT ON;
SELECT top 1 @login = [carrierLogin],@password = [carrierPassword]
  FROM [carrier_account] where carrierLogin = @accountNumber
  order by clientId, id
END

Try for the result: 
SELECT *FROM [carrier_account] 
DECLARE @login varchar(20),@password varchar(50)
exec [endicia].[credentialLookup] '588251',@login OUTPUT,@password OUTPUT
SELECT 'login'=@login,'password'=@password

使用这个查询，你可以执行任何存储过程(带或不带输出参数):

DECLARE @temp varchar(100)  
EXEC my_sp
    @parameter1 = 1, 
    @parameter2 = 2, 
    @parameter3 = @temp output, 
    @parameter4 = 3, 
    @parameter5 = 4
PRINT @temp

这里@temp的数据类型应该与存储过程中的@parameter3相同。

首先，声明输出变量:

DECLARE @MyOutputParameter INT;

然后，执行存储过程，你可以不带参数名，就像这样:

EXEC my_stored_procedure 'param1Value', @MyOutputParameter OUTPUT

或者使用参数名:

EXEC my_stored_procedure @param1 = 'param1Value', @myoutput = @MyOutputParameter OUTPUT

最后，你可以通过执行SELECT命令查看输出结果:

SELECT @MyOutputParameter 

下面是存储过程

create procedure sp1
(
@id as int,
@name as nvarchar(20) out
)
as
begin
select @name=name from employee where id=@id
end

这是执行这个过程的方法

 declare @name1 nvarchar(10)
    exec sp1 1,@name1 out
    print @name1
