In SQL server, how can I query an Oracle Timestamp column over a Linked server connection?

Question

The query I have made in oracle does not work with linked server with sql server 2008.

The OLE DB provider "MSDAORA" for linked server "ORACLE" supplied invalid metadata for column "DATETIME_INS". The data type is not supported.

The query:

select * from ORACLE..U_GERAN.CELLSTATS4

What are the modification that must be done to execute the query.

Answer 1

Try,

SELECT * 
FROM OPENQUERY(ORACLE, 'select cast(DATETIME_INS as DATE) from U_GERAN.CELLSTATS4')

You can add the other columns to the query once that column works.
