交换一个表中的两个字段——通过临时表

CREATE TABLE #t1(OrderId INT PRIMARY, src VARCHAR(50),Campaign VARCHAR(50))

INSERT INTO #t1(OrderId,src)

SELECT o.OrderId, src FROM CustomerInfo.dbo.Analytics_Campaign_Info(NOLOCK) AS aci

INNER JOIN Diapers.dbo.orders(NOLOCK) AS o ON aci.OrderId=o.OrderId

WHERE o.OrderDate BETWEEN '2011-08-08 00:00:00' AND GETDATE()

UPDATE a

SET a.src=b.Campaign,a.Campaign = b.src

FROM

CustomerInfo.dbo.Analytics_Campaign_Info a

INNER JOIN #t1 b ON a.OrderId=b.OrderId
