SQL 服务器：更新连接表中的多条记录

Question

我在测试环境中使用 SQL Server 2008 R2 Express，在生产环境中使用完整版。我写了一个 select 语句来查找我要更新的所有记录。其中大约有 1200 个。它连接多个表并且 selection 基于多个字段。

我想要做的是把它变成一个更新语句，其中所有匹配的记录都更新了相同的文件，即 dFinalised 设置为 '2015-01-14 00:00:00.000'

我运行我的更新查询

时收到以下错误

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

我想我将不得不以某种方式嵌套它，但我找不到足够简单的示例来遵循。

select 语句相当简单

SELECT lMeetingRegisterID
      ,sPlanNumber
      ,sName
      ,sDescription
      ,dMeeting
      ,sMeetingTime
      ,bManaged

  FROM [Strata].[dbo].[MeetingRegister]
  inner Join MeetingType on MeetingRegister.lMeetingTypeID = meetingtype.lMeetingTypeID
  inner Join OwnersCorporation on MeetingRegister.lOwnersCorporationID = OwnersCorporation.lOwnersCorporationID
  inner Join tbluser on OwnersCorporation.lUserID = tblUser.lUserID

  WHERE dFinalised = '1900-01-01 00:00:00.000'
  AND dMeeting < '2014-07-01 00:00:00.000' 
  AND bManaged != 'N'

这是我对更新查询的尝试。

Update dbo.MeetingRegister
set dFinalised = '2015-01-14 00:00:00.000'
from dbo.MeetingRegister
  inner Join MeetingType on MeetingRegister.lMeetingTypeID = meetingtype.lMeetingTypeID
  inner Join OwnersCorporation on MeetingRegister.lOwnersCorporationID = OwnersCorporation.lOwnersCorporationID
  inner Join tbluser on OwnersCorporation.lUserID = tblUser.lUserID
Where dFinalised = '1900-01-01 00:00:00.000'
  AND dMeeting < '2014-07-01 00:00:00.000' 
  AND bManaged = 'N'

Answer 1

尝试table表达式

WITH C AS (
SELECT lMeetingRegisterID
      ,sPlanNumber
      ,sName
      ,sDescription
      ,dMeeting
      ,sMeetingTime
      ,bManaged
      ,dFinalised

  FROM [Strata].[dbo].[MeetingRegister]
  inner Join MeetingType on MeetingRegister.lMeetingTypeID = meetingtype.lMeetingTypeID
  inner Join OwnersCorporation on MeetingRegister.lOwnersCorporationID =    OwnersCorporation.lOwnersCorporationID
  inner Join tbluser on OwnersCorporation.lUserID = tblUser.lUserID

  WHERE dFinalised = '1900-01-01 00:00:00.000'
  AND dMeeting < '2014-07-01 00:00:00.000' 
  AND bManaged != 'N'
)
Update C
set dFinalised = '2015-01-14 00:00:00.000'
