Linked Server in SQL

Is there a way to link to a MySQL table on a remote server using SQL Server Management Studio and have it "act" like a normal table on our in house MSSQL server.  We use MS Access as our front end.
Currently we get around this by installing MySQL connector on each workstation and connect to our front end (Access) to get this to work but would like not to do this.

have it "act" like a normal table on our in house MSSQL server. 
Hello Josh,
Not as a "table", but as a complete server; as a linked server, see

  • Cannot kill a session that is running a query on a linked server in SQL Server 2008 R2

    Hi,
    Cannot kill a session that is running a query on a linked server  in SQL Server 2008 R2.
    When I try to kill, it status shown as "KILLED/ROLLBACK"
    I have facing the issue from long back. I searched many and none of them worked for me
    Any help is greatly appreciated
    Thanks

    I guess its stuck, can you see some blocking or any other process blocking the rollback.
    can you check rollback status using below command. Or you can use sp_who2 and check status column
    select percent_complete,estimated_completion_time from sys.dm_exec_requests
    where spid=xxx

  • How to create a linked server to SQL in Oracle?

    I am able to create a linked server to Oracle in SQL.. But I do not know the steps to create a linked server too SQL in Oracle.
    How to create a linked server to SQL in Oracle? After creating the linked server to SQL, I would like to create triggers in Oracle DB to insert records into SQL DB.

    There are 2 products in Oracle you can use to link to a MS SQl Server. The first one is for free and it is called Database Gateway for ODBC. With a suitable 3rd party ODBC driver you can connect to any foreign database. The second gateway is our commercial gateway and it is called Oracle Database Gateway for MS SQL Server. It is designed for MS SQl Server connections and more powerful then Dg4ODBC. It know how to map a lot of Oracle functions to SQL Server equivalents and you can also use it to directly call SQL Server procedures or functions. This dedicated SQL server gateway is also able to participate in distributed transactions.
    But again, this is a commercial gateway and you have to purchase a license for that second gateway, the Database Gateway for MS SQl Server.

  • Connecting Oracle 9i as a linked server of SQL Server 2000

    I have a problem inserting String values into Oracle 9i as a linked server or SQL Server 2000.
    When I run the following in SQL Analyzer:
    insert into ORACLEOLE..ADMIN.FM_SQL values('asdf','qwer');
    The result msg is:
    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.
    OLE DB error trace [Non-interface error:  Column 'FM_ID' (compile-time ordinal 1) of object '"ADMIN"."FM_SQL"' was reported to have a DBTYPE of 129 at compile time and 130 at run time].
    Is this a problem that the Charaterset of Oracle 9i being 'ALU32UTF8' ?
    I have tried changing the field's type to varchar2, char, nvarchar2 and nchar...and they didn't work.
    However, when the field type is a number(10) and I insert to the table integer values, the sql works fine.
    so..any data mapping need to be done explicitly?
    Thanks in advance.

    Based on my reading of the ANSI SQL-92 standards, table names are supposed to be in upper case.
    "of course, any lower case letters appearing in a <regular identifier> will have been converted to the corresponding upper case letter before the <identifier> is stored in any table of the Information Schema"
    http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt
    Given that table names are supposed to be in upper case and they are in fact in upper case, why don't you just ask for them in upper case in the first place?

  • Adding a table to a linked server in SQL

    Hi
    I have a linked server in SQL server management studio.
    It has a list of oracle tables that can be reached through it. To add tables to the list do i need set up some permissions on the Oracle side?
    thanks a lot for any help

    To add to what Sunny posted. If the linked server uses a fixed user/password to connect to Oracle then in the Oracle database all you need do is get the required object privileges granted to the Oracle username being used in the linked server to Oracle. The grant can be direct to the username or to a role the username has been granted.
    If the MS SQL Server Linked Server to Oracle does not use a fixed user then the SQL Server usernames have to also exist in Oracle or have been mapped via the linked server definition to an Oracle username. Different SQL Server users can have different Oracle usernames associated to them via the linked server definition so you may need the Oracle grants issued to one or more Oracle usernames.
    Most linked servers use fixed users to connect to Oracle but you need to be aware this is not always true and when it is not true the list of tables shown under the linked server can vary based on the SQL Server user logged in.

  • Linked Server from SQL 2008 to Connect to 2012 read only replica never works

    I have two Production Database Servers
    1. SQLServer2008 (2 Nodes Cluster)
    2. SQLServer2012 with 2 read only replica (3 Nodes Cluster)
    I would like to draw a line here, We have routing table and URL working perfectly fine. 
    We have tested LINKED Server from 2012 Box to production Server by Specifying APPLICATIONINTENT = ReadOnly; it works perfectly fine, the routing is being used.
    When we create linked server from SQL Server 2008 Box (Please note we have installed SQL Server 2012 Client tools on this box and Restarted the Servers) using the below script
    USE [master]
    EXEC master.dbo.sp_dropserver @server=N'AGL1', @droplogins='droplogins'
    GO
    EXEC master.dbo.sp_addlinkedserver @server = N'AGL1'
    ,@datasrc='AGL1'
    ,@provider='SQLNCLI11'
    ,@provstr='ApplicationIntent=ReadOnly;Database=AdventureWorks2012'
    Linked Server is created, Now when I run the Query 
    exec ('select @@servername') at AGL1
    It always brings the Primary READ/WRITE node name only, after lots of research I found that, this linked Server is always using SQL Native Client 10.0 only, even after creating Linked Server using SNC 11, That is the reason it is not going to routing
    table. Its always connecting to Primary node.
    Below is the way I found it, on 2012 Production Server I executed below Query
    SELECT session_id, protocol_type, driver_version = 
    CASE SUBSTRING(CAST(protocol_version AS BINARY(4)), 1,1)
    WHEN 0x70 THEN 'SQL Server 7.0'
    WHEN 0x71 THEN 'SQL Server 2000'
    WHEN 0x72 THEN 'SQL Server 2005'
    WHEN 0x73 THEN 'SQL Server 2008'
    ELSE 'SQL Server 2012' 
    END,client_net_address ,client_tcp_port,local_tcp_port ,T.text
    FROM sys.dm_exec_connections
    CROSS APPLY sys.dm_exec_sql_text(most_recent_sql_handle) AS T
    The help is taken from msdn (Link Provided below) for the above Query
    https://msdn.microsoft.com/en-us/library/dd339982.aspx
    and I found it always uses SQL Server 2008 SNC.
    My Question is, is there a way to force SQL Server to use SQL Server Native Client 11.
    Has anyone tried this setup?
    Thank you in advance.

    Unfortunately no, there is no other way of forcing it without restart. The SQL Server stack has no idea of the existing Native Client as it booted prior its installation. And you cannot force "DLL reload" without proper service restart.

  • Have trouble query after creating a linked server from SQL Server 2008 to EXCEL 2007

    I created a linked server from SQL Server 2008 Management Studio Express to an EXCEL 2007 workbook using:
    sp_addlinkedserver @server='LSERVER_EX0', @srvproduct='EXCELDATA', @provider='Microsoft.ACE.OLEDB.12.0', @datasrc='C:\Temp\abc.xlsx', @provstr='EXCEL 12.0'
    The linked server LSERVER_EX0 was created, but I cannot see any table(excel sheet), and when i ran the following to query tables,
    sp_tables_ex 'LSERVER_EX0'
    I got:Cannot obtain the schema rowset "DBSCHEMA_TABLES" for OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "LSERVER_EX0". The provider supports the interface, but returns a failure code when it is used.
    Any hint why?
    on another note, i was able to import the EXCEL sheets using the Import and Export Data wizard, but i cannot control the column data type and size in this way.

    Open management studio, goto "Server Objects"->"Linked Servers"->Providers, select the provider you use, right click it and in provider options, check "Allow inprocess".

  • Memory leak issue with link server between SQL Server 2012 and Oracle

    Hi,
    We are trying to use the linked server feature with SQL Server 2012 to connect SQL server and Oracle database. We are concerned about the existing memory leak issue.  For more context please refer to the link.
    http://blogs.msdn.com/b/psssql/archive/2009/09/22/if-you-use-linked-server-queries-you-need-to-read-this.aspx
    The above link talks about the issues with SQL Server versions 2005 and 2008, not sure if this is still the case in 2012.  I could not find any article that talks about if this issue was fixed by Microsoft in later version.
    We know that SQL Server process crashes because of the third-party linked server provider which is loaded inside SQL Server process. If the third-party linked server provider is enabled together with the
    Allow inprocess option, the SQL Server process crashes when this third-party linked server experiences internal problems.
    We wanted to know if this fixed in SQL Server 2012 ?

    So your question is more of a information type or are you really facing OOM issue.
    There can be two things for OOM
    1. There is bug in SQL Server which is causing the issue which might be fixed in 2012
    2. The Linked server provider used to connect to Oracle is not upto date and some patch is missing or more recent version is to be used.  Did you made sure that you are using latest version.
    What is Oracle version you are trying to connect(9i,10g, R2...)

  • Oracle InstantClient with Linked Server in Sql Server 2005

    We are trying to connect ORACLE server from sql server 2005 using Linked Server Feature in SqlServer 2005
    Generally Oracle Client software is needed for this activity in the sql server machine.
    Can we use "Oracle InstantClient" instead of "Oracle Client Software" to connect ORACLE using Linked Servers ?
    Please give us your views, any existing reports similar to this activity
    Thanks & Regards,
    Palani

    Thanks for your reply
    I agree that Oracle Client software is used to connect oracle from SQL SERVER 2005.
    But my doubt is can we use Oracle InstantClient instead of Oracle Client software to connect oracle from SQL SERVER 2005
    with respect to Oracle Instant Client - I would like to know the development steps (Not the installation steps of Oracle Instant Client in windows machine) to connect ORACLE server.
    Thanks & Regards,

  • UCCX 10.1 - Linked Server - Copying HR data to external SQL Server for reporting

    I have a customer that is migrating from UCCX 7 to UCCX 10.  They currently have a 2008 SQL Server R2 that they use for custom reports.  They have a package that runs nightly to copy relevant data from UCCX 7 to the their server and then run reports daily against that database.   Pretty easy when everything is in MS SQL.  My plan was to set up a linked server in SQL 2008 to the UCCX server.  This would allow me to easily run a query against Informix and move the data over as before.  However, I am having problems adding the linked server.
    I have installed the Informix drivers (both 32 and 64 bit) during the troubleshooting.
    The DSN is created and connects to UCCX just fine.
    When I attempt to add the linked server using 64 bit driver DSN I get the following:
    Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "UCCX101".
    OLE DB provider "MSDASQL" for linked server "UCCX101" returned message "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".
    OLE DB provider "MSDASQL" for linked server "UCCX101" returned message "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".
    OLE DB provider "MSDASQL" for linked server "UCCX101" returned message "[Informix][Informix ODBC Driver][-11302] Insufficient Connection information was supplied". (.Net SqlClient Data Provider)
    When I attempt to add the linked server using the 32 bit driver DSN I get the following:
    Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "32UCCX101".
    OLE DB provider "MSDASQL" for linked server "32UCCX101" returned message "[Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application". (Microsoft SQL Server, Error: 7303)
    It appears to me there is a 32/64 bit conflict no matter route I go.
    Can anyone tell me what I am missing?
    Is there a better approach to take to achieve the ultimate goal?
    Any suggestions are greatly appreciated.
    TIA
    John

    I have created linked servers on an SQL2K box that points back to CCX. First off, you have to set the password for the UCCX HR user to some known value.
    exec sp_dropserver 'fonccx9_01', 'droplogins'
    EXEC sp_addlinkedserver
    @server='fonccx9_01', -- Name of the Linked Server, when it is created.
    @srvproduct='Microsoft OLE DB Provider for ODBC', -- OLE DB Provider.
    @provider='MSDASQL', -- Provider_name.
    @datasrc ='fonccx9-01', -- DSN Name of the ODBC Data Source.
    @provstr= -- ODBC Connection String.
    'Driver={IBM Informix ODBC};Server=fonccx9_01_uccx;Database=db_cra; Uid=uccxhruser; Pwd=Some-Password;'
    EXEC sp_addlinkedsrvlogin
        @rmtsrvname = 'fonccx9_01',
        @useself = 'FALSE',
        @rmtuser = 'uccxhruser',
        @rmtpassword = 'Some-Password'
    Note that the server name is "fonccx9-01", but the dash is an illegal character in the server name, so you have to change that to an underscore. You still have to manually build the ODBC data source on the box where you are trying to create the linked server.

  • OraOledb for 64-bit, Linked Servers and SQL Server 2005 issues

    Our environment is : SQL Server 2005, Windows Server 2003, 64-bit and 32-bit operating systems.
    Problem on 64-bit operating system box: (32-bit works fine).
    I am trying to access Oracle 10g database using linked server from our SQL Server 2005. In case of number fileds i got the following error:
    Invalid data for type "numeric".
    After going through one of the posting in this forumn i was able to resolve the problem by converting those column values to char while querying and then converting them back to numeric type on SQL server side.
    But today i ran into another problem. There is a VARCHAR2 column. I was able to retrieve the data yesterday for that column but today i am getting a blank recordset. If i exclude the colum from the query then i am getting all the rows.
    I am querying against a view and it has got a number of columns whose data type is VARCHAR2.
    Again the problem is on 64-bit operating system only. We have a 32-bit operating system on which i am able to retrieve the data including this column. I looked at the data and everything looks OK. No funny characters etc.
    I tried workarounds like using cast, to_char, checking for nulls etc., Nothing works.
    Any help is greately appreciated. Thanks.

    Did you find a resolution for this? We have similar problem. Set up a linked server in SQL 2006 to Oracle (running on Windows 64-bit) Linked server works and views I had set up were working but they added some new data in the Oracle test database I am using and now I get errors on one of the views.
    Error I am getting on the view is "Cannot initialize the data source object of OLE DB Provider "OraOLDEDB.ORacle" for the linked server"
    If I fine tune my queries to find the specific table or view that is at issue, then I get the error "inconsistent metadata for a column"

  • SQL 2000 LINKED SERVER ERROR 7303 WITH SQL 2012 ON WINDOWS SERVER 2012 R2

    Hi all,
    I have a problem with SQL Server 2012 and a linked server for SQL 2000 database.
    System specification:
    Windows server 2012 64 bit
    SQL SERVER 2012 64 bit
    REMOTE SERVER SQL 2000 32 bit
    I've installed sql native client 32bit,create a SYSTEM DSN odbc connection with "SQL Server" driver named "MYSERVER".
    Create a linked server with the query below in SQL 2012:
    EXEC master.dbo.sp_addlinkedserver @server =N'MYSERVER', @srvproduct=N'MYSERVER', @provider=N'MSDASQL', @datasrc =N'MYSERVER', @location=N'System';
    EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'MySERVER',@useself=N'True',@locallogin=NULL,@rmtuser=NULL,@rmtpassword=NULL
    GO
    but when i browse the linked server i receved error 7303.

    You need 64-bit MSDASQL. It is the bitness of the server you are connecting from that matters. 64-bit executables cannot hook into 32-bit DLL.
    However, I suspect that you will not get things to work anyway. At least I have not seen anyone this far who has been able to set up a linked server from SQL 2012 to SQL 2000. I know that when I tried this, the following providers had this result:
    SQLNCLI11 - does not support connections to SQL 2000.
    SQLNCLI10 - failed with some obscure message that I don't recall.
    SQLNCLI - Don't recall that the problem was here.
    SQLOLEDB - SQLOLEDB is always replaced with the most recent version of SQLNCLI, so this fails because of lack of support.
    I don't think I got through all version of the ODBC drivers, though.

  • How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?

    How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?
    Let's say the SQL Server and Oracle Database are in the same Company Internet Network.
    I have the code, but I do not know how to use it. Such as what is System DSN Name? Where could I get it. What does it look like?
    Do I need to install any Oracle Client Software in order to link from SQL Server to Oracle? Or SQL Server has the built-in drivers installed already that I can directly create a Linked Server from SQL Server to Oracle?
    I need to know details. Thanks.
    USE master
    go
    EXEC sp_addlinkedserver
         @server  = '{Linked Server Name}'
        ,@srvproduct = '{System DSN Name}'
        ,@provider  = 'MSDASQL'
        ,@datasrc  = '{System DSN Name}'

        ,@rmtuser  = '{Oracle User Name}'
        ,@rmtpassword = '{Oracle User Password}'

    You need an OLE DB provider for Oracle. There is one that ships with Windows, but it only supports very old versions of Oracle. Oracle has an OLE DB provider that you can use. I don't know if it's part of Oracle Client or how it is bundled.
    You should not use MSDASQL or any DSN.
