在SQL Server中使用MERGE時出錯（帶有openquery和鏈接服務器）

Question

我正在嘗試在SQL Server 2008 R2中編寫一個存儲過程，該存儲過程將執行以下操作：

1. 創建一個臨時表
2. 基於（Oracle）openquery select執行插入以填充臨時表
3. 與現有表合並並更新臨時表的內容

但是，嘗試時出現錯誤，我想知道我是否真的在以正確的方式進行操作。

步驟如下：

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

我當前收到的錯誤是：

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

目標表中肯定存在“ healthmainstudrecid”列，但無論如何我都不確定要確定實際引用的是哪個表（源/目標）。 我也無法查詢臨時表來確定它是否已成功創建。

任何幫助將不勝感激。

編輯：也許還值得一提的是，在SSMS中，該行用紅色下划線標出：

MERGE INTO HEALTHMAINSTUDREC H

隨着消息：

Invalid object name 'HEALTHMAINSTUDREC'.

Answer 1

#SyncHealthMainStudRecTemp有列HEALTHMAINSTUDRECIDID ，不healthmainstudrecid 。 注意雙ID 。

在insert into #SyncHealthMainStudRecTemp之前，先刪除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())

編輯：

如果您有區分大小寫的排序SQL_Latin1_General_CP1_CS_AS ： SQL_Latin1_General_CP1_CS_AS 。 因此，您需要保留聲明的表名和列名。 如果表具有列HEALTHMAINSTUDRECIDID，則在區分大小寫的排序規則中，您將無法將其稱為HealthMainStudRecid。
