Question

这是我的代码我在触发器中第二次更新后变老了StartDateUtc和EndDateUtc

第一次当我更新我的价值时，它的工作正常，但第二次它的旧价值请给我一些建议

IF EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[NewsUpdateTrigger]'))
    DROP TRIGGER [dbo].[NewsUpdateTrigger]
    GO
    CREATE TRIGGER [dbo].[NewsUpdateTrigger]
           ON [dbo].[News] 
   FOR  UPDATE
    AS
    BEGIN


 SET NOCOUNT ON;
   DECLARE @EntityId INT
   DECLARE @EntityName varchar(Max)
   DECLARE @IsPublish bit
   DECLARE @LanguageId int
   DECLARE @StoreId int
   DECLARE @InTime Datetime  
   SELECT @EntityName='News'



                     DECLARE @StatDate DateTime
                     DECLARE @EndDate DateTime

                     SELECT @EntityId = DELETED.Id FROM DELETED 
                     SELECT @IsPublish = DELETED.Published FROM DELETED 
                     SELECT @StatDate= DELETED.StartDateUtc FROM DELETED 
                      SELECT @EndDate= DELETED.EndDateUtc FROM DELETED 

             IF      EXISTS (SELECT * FROM Incremental_Solr_Custom where EntityName='News' and EntityId  = @EntityId)
             BEGIN
                     --If StartDateUtc and  EndDateUtc expire Manually Set the is Publish=False
              IF     EXISTS (SELECT * FROM DELETED  WHERE StartDateUtc NOT BETWEEN Cast( GETDate() as date) AND Cast( GETDate() as date)
                     AND Cast( GETDate() as date) NOT BETWEEN StartDateUtc AND EndDateUtc )
            BEGIN

                     UPDATE Incremental_Solr_Custom SET SolrStatus =1,IsPublish=0 WHERE EntityId = @EntityId AND EntityName='News';
                     Insert into TriggerTesterTable(ErrorMethodName)values(' If StartDateUtc and  EndDateUtc expire Set the is Publish=False  '+ cast( @StatDate as  varchar) + '   '+cast( @EndDate as  varchar))
             END

                     --StartDate and EndDate is Not expire Get From News Table
             IF      EXISTS (SELECT * FROM DELETED  WHERE StartDateUtc  BETWEEN Cast( GETDate() as date) AND Cast( GETDate() as date)
                     OR Cast( GETDate() as date) BETWEEN StartDateUtc AND EndDateUtc)
             BEGIN
                     SELECT @IsPublish = DELETED.Published FROM DELETED 
                     UPDATE Incremental_Solr_Custom SET SolrStatus =1,IsPublish=@IsPublish WHERE EntityId = @EntityId AND EntityName='News';
                     Insert into TriggerTesterTable(ErrorMethodName)values('StartDate and EndDate is Not expire Get IsPublish from News  '+cast( @StatDate as  varchar) + '   '+cast( @EndDate as  varchar));
             END

     END

END

我认为您正在创建更新触发器，但您正在使用DELETED表（也称为魔术表）而不是INSERTED表。请参阅此链接，它可能对您有所帮助https://www.mindstick.com/Articles/12187/use-of-dml-dll-and-logon-trigger-in-sql

此外，你可以使用'而不是触发'的概念，因为插入是某些条件的基础。

使用此SELECT * FROM INSTEAD放置SELECT * FROM DELETED

触发后未获得更新触发器
