在存儲過程中執行存儲過程

Question

我想在存儲過程中執行存儲過程，例如，

EXEC SP1 

BEGIN 

EXEC SP2 
END 

但我只想SP1後SP2運行完畢後才能完成，所以我需要找到SP1一種方式來等待SP2之前SP1端完成。

SP2被作爲SP1一部分執行的，所以我有這樣的：

CREATE PROCEDURE SP1 
AS 
BEGIN 

EXECUTE SP2 

END 

Answer 1

這就是它的工作原理如何存儲過程才能運行，你不需要開始只是像

exec dbo.sp1 
exec dbo.sp2 

Answer 2

下面是我們其中一個執行其中多個存儲過程的示例：

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

T-SQL不是異步的，所以你真的別無選擇，只能等到SP2結束。幸運的是，這就是你想要的。

CREATE PROCEDURE SP1 AS 
    EXEC SP2 
    PRINT 'Done' 

Answer 4

嗨我發現我的問題是SP2執行SP1時不從SP1內執行。

下面是SP1的結構：

ALTER PROCEDURE SP1 
AS 
BEGIN 

Declare c1 cursor.... 

open c1 
fetch next from c1 ... 

while @@fetch_status = 0 
Begin 

... 

Fetch Next from c1 
end 

close c1 

deallocate c1 

exec sp2 

end 

Answer 5

你的SP2可能是不是因爲在SP1早期代碼的一些故障，從而未達到EXEC SP2上運行。

請發佈您的整個代碼。

Answer 6

內聯我們根據需要使用的存儲過程。 例子就像我們在查詢中使用不同的值不同的相同的參數..

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
