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。

操作步骤示例:

Create Procedure [dbo].[test]
@Name varchar(100),
@ID int Output   
As  
Begin   
SELECT @ID = UserID from tbl_UserMaster where  Name = @Name   
Return;
END     

如何调用这个过程

Declare @ID int    
EXECUTE [dbo].[test] 'Abhishek',@ID OUTPUT   
PRINT @ID

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

你可以这样做:

declare @rowCount int
exec yourStoredProcedureName @outputparameterspOf = @rowCount output

简单的方法是在Sql Server Management Studio (SSMS)中右键单击该过程，选择“Execute stored procedure…”，并根据提示为输入参数添加值。然后，SSMS将生成代码以在新的查询窗口中运行过程，并为您执行它。您可以研究生成的代码，了解它是如何完成的。
