  • 0

I was using OpenQuery To get row set from Oracle table into my SQL Server. Then i find there is something known as OPENROWSET to fetch all rows

but it didnt worked for me.

SELECT a.*
FROM OPENROWSET('MSDASQL',
   'DRIVER={SQL Server};SERVER=INDIANBANK;UID=ags;PWD=mypass',
   'Select * From ATM_PROGNOSIS.IR_ATMMON_AGS') AS a

Error :-

OLE DB provider "MSDASQL" for linked server "(null)" returned message "[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()).".
OLE DB provider "MSDASQL" for linked server "(null)" returned message "[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "(null)".

Name of My DSN : INDIANBANK

I have used Microsoft OLE DB Provider for ODBC Driver To Create Linked Server to connect to oracle (ORACLE DB IS LOCATED ON REMOTE SERVER)

My DSN Show Test Connection Succeeded . Same as for My Linked Server.

When i execute following query Select * From openquery(IndianBank,'Select * From ATM_PROGNOSIS.IR_ATMMON_AGS') It retrieve only one row

My Linked SERVER CODE :-

EXEC master.dbo.sp_addlinkedserver @server = N'INDIANBANK', @srvproduct=N'IndianBankOracle', @provider=N'MSDASQL', @datasrc=N'INDIANBANK'
EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'INDIANBANK',@useself=N'False',@locallogin=NULL,@rmtuser=N'ags',@rmtpassword='########'

    If you used the string like this “‘MSDASQL’,’DRIVER={SQL Server};SERVER=INDIANBANK;UID=ags;PWD=mypass’, ‘Select * From ATM_PROGNOSIS.IR_ATMMON_AGS'” you got DSN-less connection so tests of DSN are useless.

    I recommend you to take this driver
    Oracle Data Provider for .NET
    It’s much more friendly with Oracle.

    Here is
    the example for ODP.NET
    where tuning is described.

    And here is
    the full docs for ODP.NET

    Hope this helps 🙂

    See my comments below.

    P.S. For Microsoft driver the parameters are shown here
    Microsoft OLE DB Provider for ODBC
