Update  s
Set s.ServiceDeliverySettingID = 
                                Case  
                                When s.HCCMRRServiceType  = '01' Then (Select ServiceDeliverySettingID from [DSDW].[Dim].[ServiceDeliverySetting]
                                                                     Where HCCValue = '08')

                                                             Where HCCValue = '06') 
                                When s.HCCMRRServiceType = '50' 

                                Then

                                case 

                                   when s.InterventionCode = 'ICR' then ( Select ServiceDeliverySettingID from [DSDW].[Dim].[ServiceDeliverySetting]
                                                             Where HCCValue = '97')
                                   when s.InterventionCode = 'RC' then ( Select ServiceDeliverySettingID from [DSDW].[Dim].[ServiceDeliverySetting]
                                                             Where HCCValue = '06')
                                    when s.InterventionCode = 'ICFCH' then ( Select ServiceDeliverySettingID from [DSDW].[Dim].[ServiceDeliverySetting]
                                                             Where HCCValue = '02')



                              End
From [DSDW].[Staging].[HCCMRRBuildService] s

第15行，第15行，状态1，第33行关键字“From”附近的语法不正确。

当我执行上述更新查询时，有人可以帮我解释一下我收到错误消息的原因吗？

您缺少END

Update  s
Set s.ServiceDeliverySettingID = 
        Case

Answer 2

首先看，你有一个嵌套的CASE，但我只看到一个END。您需要再添加一个END来完成父CASE语句集。
