我有这个观点: 创建视图 AS
SELECT
p.pr_id
,p.arenda
,p.PlotArea
,p.OwnershipTitle
,p.Price
,p.NotaryCosts
,p.AgentFee
,p.CtrNO
,isnull(p.Price,0)-isnull(a.Price,0) as Diferente
,isnull(p.Price,0)+isnull(p.NotaryCosts,0)+isnull(p.AgentFee,0) as TotalCosts
from nbProcuri p
left JOIN nbAchizitii a
ON p.PlotArea = a.PlotArea and p.CtrNo=a.CtrNo
where a.CtrNO is null and a.PlotArea is null
我想将这两个表与另一个名为Cadastrial的表相关联,其中我还有一个名为PlotArea的列。如果p.PlotArea = c.PlotArea,则列p.arenda应该使用值'yes'更新自己,否则填充no。 这有可能吗? 谢谢!
答案 0 :(得分:1)
像这样:
UPDATE p
SET p.arenda = CASE WHEN p.PlotArea IS NULL THEN 'no' -- For not matched
ELSE 'yes' -- for matched
END
FROM nbProcuri p
LEFT JOIN Cadastrial c ON p.PlotArea = c.PlotArea
LEFT JOIN nbAchizitii a
ON p.PlotArea = a.PlotArea and p.CtrNo = a.CtrNo
WHERE a.CtrNO IS NULL
AND a.PlotArea IS NULL;
