MSSQL Linked Server To Oracle RDB

Jul 23, 2005

Hi,

I am using MSSQL 2k, and I have a linked server set up to an Oracle RDB
version 7. It goes thru an OLE DB provider for ODBC drivers on a system
DSN, which is using an Oracle RDB ODBC driver version 3.0.2.

The problem occurs when I send a query that returns zero rows - query
analyzer just does not complete nor return. This problem is not seen
when there are rows being returned.

I ran a trace and this is the error message I get-:
Non-interface error: OLE DB provider MSDASQL returned an incorrect
value for DBPROP_CONCATNULLBEHAVIOR which should be either
DBPROPVAL_CB_NULL or DBPROPVAL_CB_NON_NULL

Anybody who experienced this before has a solution?

Thanks,
Lawrence

Trouble With: Linked Server To Oracle Using OraOLEDB.ORacle Provider

Jan 11, 2007

Hi--

 

I am running SQL Server 2005 on Win2k3:

Microsoft SQL Server Management Studio      9.00.2047.00
Microsoft Analysis Services Client Tools      2005.090.2047.00
Microsoft Data Access Components (MDAC)      2000.086.1830.00 (srv03_sp1_rtm.050324-1447)
Microsoft MSXML      2.6 3.0 4.0 6.0
Microsoft Internet Explorer      6.0.3790.1830
Microsoft .NET Framework      2.0.50727.42
Operating System      5.2.3790


I have the OraOLEDB.Oracle provider installed to the (C:oraclexe) directory.

I am having problems querying from linked oracle server.  When i setup oracle as a linked server and purposely enter an incorrect password the query i run tells me i have an incorrect password.   So it at least knows that.  when i set the correct password and run a query I get this error:

(i replaced the real server name with "someServer".)

Msg 7399, Level 16, State 1, Line 1

The OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer" reported an error. The provider did not give any information about the error.

Msg 7303, Level 16, State 1, Line 1

Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer".

 

This is how I set up my Linked server:

Provider: "Oracle Provider for OLE DB"

Product Name: SomeServer

Data Source: SomeServer

Provider String:  "Provider=OraOLEDB.Oracle;Data Source=SomeServer;User Id=MyLogin;Password=MyPassword"

 

 

The query I run is:

Select * from [Someserver].[schema or database]..[tbl_name]

 

Any help???  What am i missing?

Linked Server In NT To Oracle

Jul 15, 2002

Hi:

I configured SQL Server 7.0 by Linked Server to a Oracle db. What I found was I could select data from SQL Enterprise Manage but fail to insert any data through Query Analyst from SQL Server to Oracle. The platform for the SQL Server is NT 4.0 SP6.

Could you point out what I missed while inserting data from Query Analyst to Oracle?

Thank you very much.

Linked Server To Oracle

Jul 20, 2005

Hi,I have an Oracle (8.1) & a SQL Server 2000 database withProduction data. There are situations when I need data from both thedatabases. My first choice was to link Oracle to SQL and run DTSovernight. But this would have a 1 day latency not to mention the timeit would take.1. Has any one tried real time access via Linked server to Oracle?How good is the performance?2. The Oracle db is fairly big, so I'm kinda not in favor ofcopying the whole thing over into SQL overnight. Is there an easierway to just get only the changed records from Oracle?3. Is there a better solution to this?4. Lastly, if I use OPENROWSET or OPENQUERY, can I dynamicallychange the SQL that you pass it? e.g. can the query accept aparameter?Thanks in advanceSudhesh

Anyone using a SQL Server Linked Server to access Oracle RDB on a VMS/Alpha? What connection are you using? What is reuqired? I am using OLE DB Provider for ODBC to access an ODBC connection I setup using the Oracle ODBC driver for Oracle RDB 2.1 and it seems slow and limited. You can only use the OPENQUERY method to access data, etc.

64-bit And Linked Server To Oracle

Oct 23, 2007



We're having some trouble connecting SQL Srvr2005 to Oracle (10g) in our 64-bit environment. We have Oracle's 32-bit Ole Db provider installed and have been able to use that in SSIS to connect and return some data running in 32-bit debug mode (as long as the query isn't long, complicated or using parameters =)

However, we have some hefty queries that we need to gather some data and want to put them in a stored proc on Oracle and call it through SSIS. We tried adding our Oracle DB as a linked server and are getting some errors. I've tried the following code replacing the provider with 'OraOLEDB.Oracle.1', 'OraOLEDB.Oracle' as well as 'MSDAORA':


EXEC sp_addlinkedserver

'ORA_TSTW', 'Oracle',

'OraOLEDB.Oracle.1', 'TSTW'



EXEC sp_addlinkedsrvlogin 'ORA_TSTW', false,

'user', 'lituser',

'pw'



select * from openquery(ORA_TSTW, 'select * from lituser.customer')


We keep getting the error for each of the providers we try. I've tried it in Management Studio as well as in an Exec SQL task (with debug set to 32-bit) to no avail.


Cannot create an instance of OLE DB provider "OraOLEDB.Oracle.1" for linked server "ORA_TSTW".


I've checked and the MSDAORA.dll is registered in both C:Program Files (x86)Common FilesSystemOle DB as well as C:Program FilesCommon FilesSystemOle DB.

If we can't where we can call an Oracle stored proc, we were thinking of just using a script task to connect to Oracle and retrieve the data we need, but I have a feeling performance this way would be degraded.

Anyone have thoughts/suggestions? TIA!

Problem With MSSQL 2005 And OutProcess Linked Server

Aug 26, 2006

Hi All.

I test OLEDB provider for Interbase/Firebird servers with MSSQL 2005 [standard v9.00.1399.06] and find next problem:

If "Allow InProcess"=No - MSSQL read column data with binary blob through DBBINDING

-----

iOrdinal :12
obValue :0
obLength :0
obStatus :0
dwPart :1 [DBPART_VALUE]
dwMemOwner :0
eParamIO :0
cbMaxLen :2147483647
dwFlags :0
wType :0x80[DBTYPE_BYTES ]
bPrecision :255
bScale :255
---------

This column has flags: 0xEA [MAYDEFER | WRITE_UNKNOWN | ISNULLABLE | MAYBENULL | ISLONG]

Why MSSQL send to my provider cbMaxLen==-1 ???

Columns with fixed-length not has this problem - MSSQL create accessor with correct DBBINNDING's

----

If I configure OLEDB provider with "Allow InProcess"=Yes - All is OK. MSSQL get this column through storage-object.

Sorry for my english

Oracle Linked Server TOO SLOW!!

I need to push 40k rows daily to an Oracle database. I am on a Win2k Pro box with the 8.1 client and ADO 2.6 loaded. I've configured the linked server with the Oracle as well as the Microsoft provider and it takes over a minute to push just 24 rows, less than 100 bytes each, at it. Any suggestions?

Linked Oracle Server Performance

Jun 6, 2002

Anyone have any suggestion on increasing the performance going over a linked server? IS this connection persistent? Or does it establish a connection with each reference? Any other Providers for the connection other than Microsofts OLE DB Provider for Oracle? I imagine that building index's on the referenced oracle tables would help?

Any help, input or suggestions would help.

SQL 2012 :: Oracle Linked Server

Jun 8, 2015

I have a SQL Server 2012 instance set up with a linked server to an Oracle Database. I need to build a stored procedure (single NVARCHAR(6) parameter in: @accountID) which executes a select statement against the Oracle DB.

Everything's working fine when testing with 'EXEC (''<oraclecodeblock>'') at LINKEDSERVERNAME' if I hard code the value of @accountID in <oraclecodeblock> but when I encapsulate it all within sp_executesql and attempt to parameterize @accountID it's throwing ORA-01722 'invalid number' errors on the Oracle DB. The parameterized value is NVARCHAR as are the account numbers.

Working:
DECLARE @accountID VARCHAR(6);
SET @accountID = '10842';
DECLARE @sql NVARCHAR(MAX);
SET @sql = N'EXEC (''SELECT * from A.Accounts WHERE ID = ''''10842'''';'') AT LINKEDSERVER';

[code]...

Linked Server Problem To Oracle

Sep 7, 2007

Hello,

I have a problem which I have spent the whole day trying to resolve but with little success...

Here is the situation:

I installed the Oracle Client 9.x.x on to my production MS Windows 2003 Server running MS SQL Server 2005 Enterprise (I need to make a Linked Server connnection to an Oracle database). The problem is if I try to create the Linked Server, I get an "Oracle Client software not installed. You must have the Oracle Client software installed to create connection" message from SQL Server. This is frustrating because the software is installed and I am able to make queries through SQL*Plus to the Oracle Database...

Here is my checklist ---

1) the PATH variable on the Windows Server is set correctly to the proper ORACLE HOME directory (with proper /bin directories set as well)
2) I have an updated MDAC component installed
3) registry configuration are correct for Oracle 9i
4) created test Linked Server connections to various datasources (not Oracle)

I am assuming the tsnames.org file is set up correctly or I would be able to make queries from SQL*PLUS, is this assumption correct?

I am at a lost as to what to try next...

Any information would be greatly appreciated,

Thank you,

Linked Server (Oracle) - No Select Possible

Mar 7, 2008

Hello,

I created a linked server to Oracle on SQL-Server 2005. I have stored the remote login username and password in the security settings (option "...Be made using this security context" in the Security tab of the Linked Server Properties.

The "Test connection" function works fine, but a select doesn't for every table the user owns. What we found out is: if the table consists only of columns defined as varchar2, the select works. As soon as the table contains only one column defined as number (without scale and precision), it doesn't work. The error displayed is:

The OLE DB provider "MSDAORA" for linked server "NEXUS_FVADM" supplied inconsistent metadata for a column. The column "WEBVORZUGSTYP" (compile-time ordinal 2) of object ""FVADM"."AKZ"" was reported to have a "DBTYPE" of 130 at compile time and 5 at run time.

The Column WEBVORZUGSTYP is defined as number.

Any ideas?

Ralf

Serious Problem With Linked Server To Oracle

May 15, 2006

Hello.
I have the following problem:
I set up a linked server in SQL Server 2000 to Oracle with Oracle OLEDB provider. I see all the tables in the linked server so the connection is successful but when I tried to select from some remote table, most often I get the following error:
Server: Msg 7356, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' supplied inconsistent metadata for a column. Metadata information was changed at execution time.
MOREOVER, selecting from some of the tables, returns other errors:
* Server: Msg 7320, Level 16, State 2, Line 1
Could not execute query against OLE DB provider 'OraOLEDB.Oracle'.
or:
Server: Msg 7317, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' returned an invalid schema definition.
All these errors are very strange to me!

I set up a linked server to the same Oracle database but with Microsoft OLE DB provider for Oracle. And everything just works perfect! (I would use this provider but it does not support distributed transactions so I can't do all my job.)

I just can't understand why the Oracle OLEDB provider is not working properly.

The same situation is happening with another PC in different LAN, with different SQL server, different Oracle database and so on.

Any help will be appreciated! Thanks.

Sql Server Linked To Oracle Database...very Slow...why?

Dec 26, 2003

Hi i have a sql server instance on my system and it is linking into an oracle database on another server. When i run queries against this other server...it takes forever...

However, when i use access, and link the table and run the same query against the oracle database...it runs immediatly.

I am very confused as to why there would be such a performance difference and why sql server would run so slow.

I am wondering if it has something to do with the way i configured the linked server. there are several options that I didn't know what they meant.

collation compatible (not selected)
Data access (selected)
RPC (not selected)
RPC Out (not selected)
collation name
connection timeout
query timeout

FYI - Oracle Linked Server - OpenQuery Deletes

Aug 7, 2000

I thought this may be very helpful for those of you using SQL7 linked server to Oracle 7.3.4 Database. After much research and no answers when opening a case with Microsoft I finally figured out how to delete using Openquery. There are a few missing pieces of information that would of been a great help in BOL. The first is, the Microsoft OLE DB for Oracle is not the correct choice for the data provier as one might think. The correct choice is the Oracle Provider for OLE DB. The next important thing is that the Oracle table you are querying MUST have a unique index on at least one column not necessarily the column in your WHERE clause. Thirdly, you get much better performance and use of indexes if you put the WHERE clause inside the OPENQUERY statement. Here is the syntax that I found to work in my application:

DECLARE @ins_id varchar(7)
DECLARE @sqlstring nvarchar(2000)
Select @ins_id = '123456'
Select @ins_id = convert(int, @ins_id)
select @ins_id

select @sqlstring = 'DELETE FROM OPENQUERY(LinkedServerName,"SELECT * FROM OracleTableName WHERE I_ID = '
+ '' + @ins_id + '' + '")'
select @sqlstring

EXEC sp_executesql @sqlstring

*Note...I had an additional data conversion from varchar to integer in my statement.

I hope this information helps any others who are having trouble performing this type of task.
