Merge statement with openrowset

  • HI All

    Is it possible to run the MERGE statement using Openrowset or openquery? I tried with below statement:

    SELECT *

    FROM OPENROWSET('SQLNCLI',

    'DRIVER={SQL Server};SERVER=MYSERVER;UID=sa;PWD=mypwd',

    'MERGE dbo.tab1 AS a

    USING (SELECT * FROM [SERVERXYZ].MyDB.dbo.tab1 with (nolock)) AS b

    ON a.Id=b.id

    WHEN MATCHED THEN UPDATE SET

    a.ID=b.id

    WHEN NOT MATCHED BY TARGET THEN

    INSERT(id)

    VALUES(b.id

    )

    WHEN NOT MATCHED BY SOURCE THEN DELETE;')

    but got error:

    Msg 7357, Level 16, State 2, Line 1

    Cannot process the object "MERGE dbo.tab1 AS a

    USING (SELECT * FROM [SERVER2].DotnetNuke2.dbo.tab1 with (nolock)) AS b

    ON a.Id=b.id

    WHEN MATCHED THEN UPDATE SET

    a.ID=b.id

    WHEN NOT MATCHED BY TARGET THEN

    INSERT(id)

    VALUES(b.id

    )

    WHEN NOT MATCHED BY SOURCE THEN DELETE;". The OLE DB provider "SQLNCLI10" for linked server "(null)" indicates that either the object has no columns or the current user does not have permissions on that object.

  • Please check if you have the necessary permission to perform INSERT/UPDATE/DELETE operation on the target table.

  • yes, permissions are there. If i run the merge statement without OPENROWSET, it works.

    So i was querious if it is possible at all?

  • BOL states that OpenRowSet can be used as a Target in the merge but appears to be ambiguous as to whether it can be a source.

    Have you tried loading the data from the openrowset into a temp table then use that as the merge, another alternative could be to use a CTE to do the OpenRowSet load, but It may cause a bottleneck.

    HI All

    Is it possible to run the MERGE statement using Openrowset or openquery? I tried with below statement:

    You want to run this MERGE as a remote query on SERVER=MYSERVER.

    The MERGE uses a linked server (SERVERXYZ) table as a source.

    What server are you connected to when you run the openrowset query?

  • Sorry for replying late. I am connected to MYSERVER while running the openrowset
