Question

我需要在成功插入目标表后对源表进行udpate（从字段中剪切出一个字符串）。我找到了一些类似任务的例子，但不完全是这样。我正在寻找这样的东西：

INSERT INTO [dbo].[ConditionsAsignments]
       ([ConditionID]
       ,[SRCtableID])
SELECT
        8 as ConditionID   
       ,SRC.ID as SRCtableID   
FROM SRCtable as SRC 
WHERE SRC.BusinessConditionText LIKE '%Prices are ex VAT.%'

OUTPUT INSERTED.*
UPDATE SRC.BusinessConditionText = SUBSTRING(...cut out the searched text...) 
WHERE SRC.ID = SRCtableID

性能不是问题，这只是一个数据迁移脚本。

当我跟随他的评论时，对Adwaenyth的信用。

我采取了疯狂的猜测，似乎按预期工作：

CREATE TABLE #IDins(ID INT)

INSERT INTO [dbo].[ConditionsAsignments]
       ([ConditionID]
       ,[SRCtableID])
OUTPUT INSERTED.SRCtableID INTO #IDins   -- outputing to a TEMP table
SELECT
        8 as ConditionID   
       ,SRC.ID as SRCtableID   
FROM SRCtable as SRC 
WHERE SRC.BusinessConditionText LIKE '%Prices are ex VAT.%'

UPDATE SRCtable SET BusinessConditionText = CONCAT(SUBSTRING(...cut out the searched text...)) 
WHERE ID IN (SELECT ID FROM #IDins)     -- modifiying only lines, which have inserts

GO

-- can be repeated with a different string ---

使用＆＃34;插入触发后＃34;为你的目标表。

成功INSERT到目标表后UPDATE源表？
