如何从SP中选择任何值？

Question

我喜欢SP：

CREATE PROCEDURE MySP
(
@startdate datetime = null,
@enddate datetime = null
)
AS
BEGIN
  declare @date datetime 
Set @date= convert(datetime,convert(varchar(10),getdate(),101))
  SET @startdate = ISNULL(@startdate,convert (datetime,convert(varchar(10),getdate(),101)))
select @startdate -- i want to select and view this value
END
GO

我想查看select @startdate值，我该怎么做？

Answer 1

执行存储过程。

exec MySP

结果：

(No column name)
2011-08-10 00:00:00.000

修改

带输出参数@startdate

的存储过程

alter PROCEDURE MySP
(
@startdate datetime = null out,
@enddate datetime = null
)
AS
BEGIN
  declare @date datetime 
  Set @date= convert(datetime,convert(varchar(10),getdate(),101))
  SET @startdate = ISNULL(@startdate,convert (datetime,convert(varchar(10),getdate(),101)))
END

像这样使用

declare @D datetime
exec MySP @D out
select @D
