在 SQL 服务器（使用 openquery 和链接服务器）中使用 MERGE 时出错

Question

我正在尝试在 SQL Server 2008 R2 中编写一个存储过程，它将执行以下操作：

创建一个临时文件table
基于 (Oracle) 执行插入 openquery select 填充临时 table
合并并更新临时 table 与现有 table

但是，在尝试时出现错误，我想知道我是否真的以正确的方式处理这个问题。

程序如下：

ALTER PROCEDURE [dbo].[SyncHealthMainStudRec]
AS
BEGIN
SET NOCOUNT ON

create table #SyncHealthMainStudRecTemp(
    [HEALTHMAINSTUDRECIDID] [int] NOT NULL,
    [SCHOOLNUMBER] [int] NOT NULL,
    [STUDENTID] [int] NOT NULL,
    [WHOCREATED] [nvarchar](100) NULL,
    [WHENCREATED] [datetime] NULL,
    [WHOMODIFIED] [nvarchar](100) NULL,
    [WHENMODIFIED] [datetime] NULL,
    [PSGUID] [varchar](50) NULL,
)

end
begin


insert into #SyncHealthMainStudRecTemp
select * from openquery(psdb, 
'select
    h.healthmainstudrecid,
    h.schoolnumber,
    h.studentid,
    h.whocreated,
    h.whencreated,
    h.whomodified,
    h.whenmodified,
    h.psguid
    FROM PS.HealthMainStudRec H ')

--select * from #SyncHealthMainStudRecTemp

MERGE INTO HealthMainStudRec H
USING #SyncHealthMainStudRecTemp S
ON (H.HealthMainStudRecid = S.HealthMainStudRecid) 
WHEN NOT MATCHED BY TARGET
    THEN INSERT(healthmainstudrecid, schoolnumber, studentid, whocreated, whencreated,
                whomodified, whenmodified, psguid, D_LastSynced) 
         VALUES(s.healthmainstudrecid, s.schoolnumber, s.studentid, s.whocreated, s.whencreated,
                s.whomodified, s.whenmodified, s.psguid, getdate())
WHEN MATCHED and (
    isnull(H.whocreated,'') collate SQL_Latin1_General_CP1_CS_AS <> isnull(S.whocreated,'') collate SQL_Latin1_General_CP1_CS_AS or
    isnull(H.whencreated,'') <> isnull(S.whencreated,'') or
    isnull(H.whomodified,'') collate SQL_Latin1_General_CP1_CS_AS <> isnull(S.whomodified,'') collate SQL_Latin1_General_CP1_CS_AS or
    isnull(H.whenmodified,'') <> isnull(S.whenmodified,'') or
    isnull(H.psguid,'') <> isnull(s.psguid,'')
)
    THEN UPDATE SET H.whocreated = S.whocreated,
                    H.whencreated = S.whencreated,
                    H.whomodified = S.whomodified,
                    H.whenmodified = S.whenmodified,
                    H.psguid = S.psguid,
                    H.D_LastSynced = getdate();
--OUTPUT $action, inserted.*, deleted.*;

drop table SyncHealthMainStudRecTemp

END

我目前收到的错误是：

Msg 207, Level 16, State 1, Procedure SyncHealthMainStudRec, Line 38
Invalid column name 'healthmainstudrecid'.

列 'healthmainstudrecid' 肯定存在于目标 table 中，但我不确定无论如何要确认实际上指的是哪个 table (source/target) .我也无法查询临时 table 以确定它是否已成功创建。

如有任何帮助，我们将不胜感激。

编辑：可能还值得一提的是，在 SSMS 中，此行带有红色下划线：

MERGE INTO HEALTHMAINSTUDREC H

附留言：

Invalid object name 'HEALTHMAINSTUDREC'.

Answer 1

#SyncHealthMainStudRecTemp 有列 HEALTHMAINSTUDRECIDID，而不是 healthmainstudrecid。注意双 ID.

删除 insert into #SyncHealthMainStudRecTemp 之前的 end begin。

MERGE INTO HealthMainStudRec H
USING #SyncHealthMainStudRecTemp S
ON (H.HealthMainStudRecid = S.HEALTHMAINSTUDRECIDID) 
WHEN NOT MATCHED BY TARGET
    THEN INSERT(healthmainstudrecid, schoolnumber, studentid, whocreated, whencreated,
                whomodified, whenmodified, psguid, D_LastSynced) 
         VALUES(s.HEALTHMAINSTUDRECIDID, s.schoolnumber, s.studentid, s.whocreated, s.whencreated,
                s.whomodified, s.whenmodified, s.psguid, getdate())

编辑：

伙计，你有区分大小写的排序规则：SQL_Latin1_General_CP1_CS_AS。因此，您需要在声明时保留 Table 名称和列名称。如果 table 有 HEALTHMAINSTUDRECIDID 列，当您使用区分大小写的排序规则时，您将无法将其称为 HealthMainStudRecid。
