在存储过程中执行存储过程

Question

我想在存储过程中执行存储过程,例如

EXEC SP1

BEGIN

EXEC SP2
END

但是我只想SP1在SP2完成跑步后完成所以我需要找到一种SP1等待SP2在结束前完成的方法SP1.

SP2正在执行,SP1所以我有类似的东西:

CREATE PROCEDURE SP1
AS
BEGIN

EXECUTE SP2

END

Answer 1

T-SQL不是异步的,所以你别无选择,只能等到SP2结束.幸运的是,这就是你想要的.

CREATE PROCEDURE SP1 AS
   EXEC SP2
   PRINT 'Done'

Answer 2

以下是我们的一个存储过程的示例,该存储过程在其中执行多个存储过程:

ALTER PROCEDURE [dbo].[AssetLibrary_AssetDelete]
(
    @AssetID AS uniqueidentifier
)
AS

SET NOCOUNT ON

SET TRANSACTION ISOLATION LEVEL READ COMMITTED

EXEC AssetLibrary_AssetDeleteAttributes @AssetID
EXEC AssetLibrary_AssetDeleteComponents @AssetID
EXEC AssetLibrary_AssetDeleteAgreements @AssetID
EXEC AssetLibrary_AssetDeleteMaintenance @AssetID

DELETE FROM
    AssetLibrary_Asset
WHERE
    AssetLibrary_Asset.AssetID = @AssetID

RETURN (@@ERROR)

Answer 3

我们根据需要使用的内联存储过程.像不同的示例相同的参数,我们必须在查询中使用不同的值.

Create Proc SP1
(
 @ID int,
 @Name varchar(40)
 -- etc parameter list, If you don't have any parameter then no need to pass.
 )

  AS
  BEGIN

  -- Here we have some opereations

 -- If there is any Error Before Executing SP2 then SP will stop executing.

  Exec SP2 @ID,@Name,@SomeID OUTPUT 

 -- ,etc some other parameter also we can use OutPut parameters like 

 -- @SomeID is useful for some other operations for condition checking insertion etc.

 -- If you have any Error in you SP2 then also it will stop executing.

 -- If you want to do any other operation after executing SP2 that we can do here.

END

这就是存储过程按顺序运行的工作原理，您不需要像这样开始

exec dbo.sp1
exec dbo.sp2
