sql - 语法错误

Question

下面的说法有什么问题？我不断收到以下错误消息....
服务器:消息 156，级别 15，状态 1，第 4 行
关键字“THEN”附近的语法不正确。

update oildatasetstatus
set oildatasetstatusid = 
    case 
    WHEN 5 THEN 16        
    WHEN 6 THEN 17        
    WHEN 7 THEN 18        
    WHEN 8 THEN 18        
    WHEN 9 THEN 18        
    WHEN 10 THEN 19        
    WHEN 11 THEN 20    
    End
where oildatasetlabstatusid in 
(
                select oildatasetstatusid
                from OilDataSetStatus
                inner join OilDataSet on OilDataSet.OilDataSetID = 
                    OilDataSetStatus.OilDataSetID
                where SamplePointID in 
                (
                                select SamplePointID 
                                from SamplePoint
                                where CustomerSiteID in
                                (
                                                select CustomerSiteID
                                                from CustomerSite
                                                where CustomerID = 2
                                )
                )
)

我认为您缺少要在 CASE 语句中评估的语句。

update oildatasetstatus set oildatasetstatusid =
case oildatasetstatusid
 WHEN 5 THEN 16
 WHEN 6 THEN 17
 WHEN 7 THEN 18
 WHEN 8 THEN 18
 WHEN 9 THEN 18
 WHEN 10 THEN 19
 WHEN 11 THEN 20
End
where oildatasetlabstatusid in ( select oildatasetstatusid from OilDataSetStatus inner join OilDataSet on OilDataSet.OilDataSetID = OilDataSetStatus.OilDataSetID where SamplePointID in ( select SamplePointID from SamplePoint where CustomerSiteID in ( select CustomerSiteID from CustomerSite where CustomerID = 2 ) ) )

试一试？
