Linked Server Oracle Tables - Not Able To Add To Query Designers Show Diagram Pane Via Add Table Dialogue
Apr 18, 2008
I am new to sqlserver.
1)I created a linked server to a oracle database, works fine. Now I am writing queries, using "Query Desgner", when I do a "Add table" linked server tables do not appear. Is this a limitation. I can get around the problem by creating a view.
2) When I use "Microsoft OLE DB Provider for Oracle" for linked server, some times connection seems to get lost. On one occassion, the next day it was fine, it re-established itself.
Any ideas thnx.

I have VS2008 Express and I am using Sql Server Compact Edition 3.5 which is distributed with it.
As I experienced, there is no possibility to use this database from Sql Server Management Studio (because it is version 3.5 and Management Studio demands version 3.1).
So, the only possibility to design a query is to use the built in Query Builder in Visual Studio Express. This query builder does not save the Diagram Pane content layout. I mean, when a query has 10 tables, I place these tables in the Diagram Pane in some order that makes sense (e.g. to make all relations visible). After saving and reopening the query in Query Builder, all tables are on the left side, in a complete disorder.
Is it possible to somehow save the Diagram Pane content along with the SQL ??

I linked an SQL server table into Access, but when I open the table in Access, no data shows. Do I need to set some permissions on the sql table?

I run a query using an Oracle Linked Server.
This seems to run forever.
SELECT * FROM LinkedServer..Schema.View WHERE TN= '2034561295'
...and any other field in the where clause work fine.
SELECT * FROM LinkedServer..Schema.View WHERE SPID= '8088'

I need to link some data from SQL Server 2005 with Oracle 10 data.One way is to link Oracle server to SQL Server and use ROWSOURCE forretrieving data.What other ways for joing data from both databases exist ?Can I do it from SQLCRL VB - Stored Procedure ? If yes, what objectsshall I use for opening database and running an sql ?
When I tried to import system.data.oracleclient, it was not available. Do I need to install anything for being able to use it ?
Thanks a lot.

Basic description:
We have developed a solution that sends data from SQL Server to an Oracle server as the result of a stored procedure called by a job that runs every minute. While this development worked fine in our test environment, after moving it to production it ran successfully the first minute, but the second minute the stored procedure hung, and the process could not be killed. In order to stop the process I had to stop both the SQL Agent and the MSDTC services.
Our SQL Server box:
SQL Server 2000 Standard Edition SP4
Windows 2003 Server R2 SP1
Our Oracle box:
Test: Oracle 9.2.0.6
Production: Oracle 9.2.0.4
To setup the SQL box, I did the following:
1) Install Oracle Client Tools version 10.2.0.1
2) Restart Server
3) Modify the registry as follows:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTCMTxOCI] "OracleXaLib"="oraclient10.dll" "OracleSqlLib"="orasql10.dll" "OracleOciLib"="oci.dll"
4) Modified the PATH variable so that all references to SQL Server appear in front of Oracle path references
5) Added the linked server via sp_addlinkedserver '<tns name>','Oracle','MSDAORA','<tns name>'
6) Added linked server logins via sp_addlinkedsrvlogin '<tns name>','False','<SQL user>','<Oracle User name>','<password on oracle>'
7) Changed the registry for MSDTC to match this:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTC]
"AllowOnlySecureRpcCalls"=dword:00000000
"FallbackToUnsecureRPCIfNecessary"=dword:00000001
"TurnOffRpcSecurity"=dword:00000001
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTCSecurity]
"NetworkDtcAccess"=dword:00000001
"NetworkDtcAccessAdmin"=dword:00000001
"NetworkDtcAccessClients"=dword:00000001
"NetworkDtcAccessTransactions"=dword:00000001
"NetworkDtcAccessTip"=dword:00000001
"XaTransactions"=dword:00000001
"DomainControllerState"=dword:00000000
"AccountName"="NT Authority\NetworkService"
"NetworkDtcAccessOutbound"=dword:00000001
"NetworkDtcAccessInbound"=dword:00000001
8) Stopped and restarted services in the following order:
1) MSDTC Stop
2) SQL Server Stop
3) MSDTC Start
4) SQL Server Start
The stored procedure:
In a single transaction, the stored procedure compares a production table against a logging table. If a record exists in the production table that is not in the logging table, a record is inserted into logging table, and a record sent to Oracle via an INSERT INTO OPENQUERY('INSTANCE','SELECT Column1, column2, column3,... FROM SCHEMA.TABLE')
SELECT column1,column2,column FROM SQLTable
This stored procedure has worked just fine for us in test, to either the test or production Oracle boxes, but it now fails, and hangs, in production to either the test or production Oracle boxes.
Additionally, I can run the following query via Query Analyzer from our test box to both the test Oracle and production Oracle and it runs successfully (this is NOT used in our stored procedure code, but is presented here as an indication that I think there is something wrong with the settings on our production SQL box):
SELECT * FROM OPENQUERY('INSTANCE','SELECT * FROM SCHEMA.TABLE')
When I run this same query via Query Analyzer on our Production SQL box, to either the test Oracle or production Oracle, it hangs, and I have to kill the process, and restart the MSDTC service.
Other queries that hang are:
SELECT * FROM SERVER..SCHEMA.TABLE
Additionally, I noticed that when I used this method to kill the process I would see errors like the following in the Application Event Log on the SQL box:
The XA Transaction Manager attempted to perform recovery with the XA resource manager. The XA resource manager reported that recovery was unsuccessful. DSN = MTxOCI.Dll.
Since I figured this was an aborted transaction still residing in the MSDTC log file, I would stop the MSDTC service, delete the MSDTC log file, reset the MSDTC log, and then restart the MSDTC service in order to prevent this error from occurring.
Not ALL queries from the production SQL box to production and test Oracle boxes fail. I can get results returned for this query:
SELECT COLUMN1, COLUMN2 FROM SERVER..SCHEMA.TABLE
I've been scouring the internet for about a week now, and I've run out of ideas on what to check on the production SQL box. Any suggestions would be greatly appreciated.

Hi,
I have Table A . we already have 80 columns . we have to add 65 more columns.
we are populating this table from oracle .and we need to populate those 65 columns again from the same table.
Is it a better idea to add those new 65 columns to the same table or new table.
If we go for the same table then loading time will be double, If I go for new table and If i am able to run both the packages which loads table data from same oracle server to difffrent sql tables then we should be good. But if we run in to temp space issues on oracle server . Then i have to load the two tables separately which consumes the same time as earlier one.
I was thinking if there is a way in SSIS where I can pull data from same oracle table in to two diff sql tables at same time?

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 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?

Why is it that only SOME of the tables in my database show up in the Entities pane?
There are a total of six tables in my database, yet only three of them are available to me in the Entities pane. I have looked at permissions, etc, and I am using the SA account. It seems like I should see either ALL or NONE of the tables, but that is not the case.
What am I missing?

Strange one here - I am posting this in both SQL Server and Access forums
Access is telling me it can't append any of the records due to a key violation.
The query:
INSERT INTO dbo_Colors ( NameColorID, Application, Red, Green, Blue )
SELECT Colors_Access.NameColorID, Colors_Access.Application, Colors_Access.Red, Colors_Access.Green, Colors_Access.Blue
FROM Colors_Access;
Colors_Access is linked from another MDB and dbo_Colors is linked from SQL Server 2000.
There are no indexes or foreign contraints on the SQL table. I have no relationships on the dbo_ table in my MDB. The query works if I append to another Access table. The datatypes all match between the two tables though the dbo_ tables has two additional fields not refrenced in the query.
I can manually append the records using cut and paste with no problems.
I have tried re-linking the tables.
Any ideas?
Thanks,
Brad

Hi Friends,
I want to have solution for one of the problem.
The requirement is like this :
I want to write stored procedure or function which will take parameter as SQL Server name, DB name, UserName and passwod.
This Stored proc will connect to Remote server using these parameters and will get the count of the rows in one of the table.
I created the connection using the linked server
EXEC sp_addlinkedserver @SerevrName,N'SQL Server'
EXEC sp_addlinkedsrvlogin @SerevrName, False, Null, @ServerUserName,@SerevrPws
Now I am trying to get count using following query :
set @SQLQuery = 'SELECT count(*) FROM [' + @SerevrName + '].' + @SrcDataBaseName +'.dbo.<<TableName>>'
But the question is that the execution goes this way :
exec(@SQLQuery)
Now how to assign this count value to some variable so that I can use it later ...?
Going forword I want to use cursor and get the rows in these table using cursor ...?
How can I assign values returned from any runtime query to temporary variable or table ...?
I tried another approach also:
I put remote connection and query execution in inner stored proc called usp_GetTableRowCount
set @SQLQuery = 'SELECT count(*) FROM [' + @SerevrName + '].' + @SrcDataBaseName +'.dbo.<<TableName>>'
exec(@SQLQuery)
and in outer stored proc : referenced the inner stored proc like this
exec @AFSDataRowCount = dbo.usp_GetTableRowCount <<Server Name>>,<<User Name>>, <<Password>>, <<DBName>>
The execution of dbo.usp_GetTableRowCount <<Server Name>>,<<User Name>>, <<Password>>, <<DBName>> gives me exact no of rows
but when I see value of AFSDataRowCount, I get 0.
Kindly help me out whereever I am making mistake or else pls tell me any other approach to follow.
Thanks in advance.

I have created a database with several tables. I want to create a database diagram to show the relationshipbetween the tables. Below are the steps from the SQL Server 2005 documentation on how to create a database diagram. The problem is that when I right click on the Database Diagrams folder I am only given two options. They are:"Working with SQL Server diagrams" and "Refresh"There is no menu choice to create a new database diagram. Can anyone tell me what the problem here is?
To create a new database diagramIn Object Explorer, right-click the Database Diagrams folder or any diagram in that folder.
Choose New Database Diagram on the shortcut menu.
The Add Table dialog box appears.
Select the required tables in the Tables list and click Add.
The tables are displayed graphically in the new database diagram.

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.

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

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!

HI
When you right click open table to return all rows, click on the "Show/Hide Grid pane" icon . When you click on any row the first column called "Column" a dropdown shows all the filed names of that particular table.
This feature used to work fine untill recently wherein when I click on the column, I don't get to see all the filed names but now it just shows TableName.* i.e. all columns.
This is the case when I try to create a view in enterprise manager also. When you add a table to create a view, I cannot see all the filed names . I'm not sure what to do , to get the field names to appear? Is it some kind of setting in enterprise manager.
All the info would be appreciated.

Does anyone know how to link an Oracle (8.0.6.0) database to a MS SQL 7.0 db? I have set up the ODBC and it works with no problem. I can get tables from the oracle db and bring them into MS access with ODBC so I know that it is set up correctly. I just cant get visability to the db in a sql 7 environment. Any help or sugestion would be appreciated.
Thanks
