删除在存储过程中不起作用的查询

Question

我在 sql 服务器中有一个存储过程，它在第一步中将一些数据从一个 table 插入到另一个，然后从第一个 [= 中删除第二个 table 中插入的数据16=]；可能描述的比较复杂，看代码：

ALTER PROCEDURE [dbo].[SP_Insert_NotificationUserBulk]
AS
BEGIN
  SET NOCOUNT ON;
  INSERT INTO [dbo].[NotificationUserBulk]
       ([NotificationId]
       ,[UserId]
       ,[IsNotify]
       ,[IsShow]
       ,[NotifyMethod]
       ,[NotifyDateTime]
       ,[ShowDateTime]
       ,[IsDeleted]
       ,[CreatedDate]
       ,[ModifiedDate])
 
 (SELECT 
UserId,
NotificationId,
IsNotify,
IsShow,
NotifyMethod,
NotifyDateTime,
ShowDateTime,
IsDeleted,
CreatedDate,ModifiedDate
FROM NotificationUsers WHERE IsShow=1 OR IsDeleted=1)

DELETE FROM dbo.NotificationUsers WHERE IsShow=1 OR IsDeleted=1
   RETURN
END

Insert 语句执行成功，没有问题，但在 Delete 语句中不起作用，没有任何反应。那么问题是什么，我该如何解决？

Answer 1

DELETE Query后请不要使用RETURN，尽量简单Query

DELETE FROM dbo.NotificationUsers WHERE IsShow=1 OR IsDeleted=1

Answer 2

如果这是一次性或临时查询，您可以尝试这样的操作。如果它是 oltp 那么你可以添加 TRY/CATCH 和 return 一个 success/failure 变量。

在 XACT_ABORT ON 的显式事务中，查询插入 'NotificationUsers' table，将（插入的）NotificationId 输出到临时 table，并从 'NotificationUsers' 基于温度 table.

的 INNER JOIN

ALTER PROCEDURE [dbo].[SP_Insert_NotificationUserBulk]
AS
SET NOCOUNT ON;
SET xact_abort on;

begin transaction 
    declare @NotificationId             table(NotificationId        int primary key);

    INSERT INTO [dbo].[NotificationUserBulk]
           ([NotificationId]
           ,[UserId]
           ,[IsNotify]
           ,[IsShow]
           ,[NotifyMethod]
           ,[NotifyDateTime]
           ,[ShowDateTime]
           ,[IsDeleted]
           ,[CreatedDate]
           ,[ModifiedDate])
    output inserted.NotificationId into @NotificationId 
    SELECT UserId, NotificationId, IsNotify, IsShow, NotifyMethod,
           NotifyDateTime, ShowDateTime, IsDeleted, CreatedDate, 
           ModifiedDate
    FROM NotificationUsers
    WHERE IsShow=1 
          OR IsDeleted=1;

    DELETE nu
    from dbo.NotificationUsers nu
         join @NotificationId n on nu.NotificationId=n.NotificationId;
commit
go
