    I create a linked server to Oracle in SQL 2008. tested the connection and it tests successfully.

    When I try to query

    SELECT top 10 * FROM [linkedserver]..[abc].[persons]

    GO

    it fails with following error :

    Msg 7354, Level 16, State 1, Line 1

    The OLE DB provider "OraOLEDB.Oracle" for linked server "W263UW" supplied invalid metadata for column "INACTIVE_TS".

    The data type is not supported.

    Pls help with this.

    in Oracle, what is the datatype for the column INACTIVE_TS in the [persons] table?

    if it's a TIMESTAMP, look at this post:

    I've seen issues where an "old" drivers for Oracle version 9 is used agaisnt an Oracle version 10/11 database, and returns this kind of error for BLOB/CLOB columns;

    the solution was to get a more updated Oracle driver installed on the SQL server to address the issue.

    Hi,

    I really don't know what data types does Oracle has. I was just give the name and info to create Linked server which I did successfully.

    So the person table is on Oracle side?

    yes it is on the Oracle side; because of the _TS (_TIMESTAMP?) i think that it's the timestamp datatype issue.

    pretty sure you can also resolve this by convertint the value to string or a different datetime as well.

    you could find out the datatype via TSQL:

    untested, but i think this is the syntax

    SELECT * FROM [linkedserver]..[abc].[USER_TAB_COLS] WHERE TABLE_NAME = 'PERSON' AND COLUMN_NAME = 'INACTIVE_TS'
