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

Question

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

1. 创建一个临时表
2. 基于（Oracle）openquery select执行插入以填充临时表
3. 与现有表合并并更新临时表的内容

但是，尝试时出现错误，我想知道我是否真的在以正确的方式进行操作。

步骤如下：

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

我当前收到的错误是：

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

目标表中肯定存在“ healthmainstudrecid”列，但无论如何我都不确定要确定实际引用的是哪个表（源/目标）。 我也无法查询临时表来确定它是否已成功创建。

任何帮助将不胜感激。

编辑：也许还值得一提的是，在SSMS中，该行用红色下划线标出：

MERGE INTO HEALTHMAINSTUDREC H

随着消息：

Invalid object name 'HEALTHMAINSTUDREC'.

Answer 1

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

在insert into #SyncHealthMainStudRecTemp之前，先删除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())

编辑：

如果您有区分大小写的排序SQL_Latin1_General_CP1_CS_AS ： SQL_Latin1_General_CP1_CS_AS 。 因此，您需要保留声明的表名和列名。 如果表具有列HEALTHMAINSTUDRECIDID，则在区分大小写的排序规则中，您将无法将其称为HealthMainStudRecid。
