Using Oracle SQLDeveloper to access SQLServer

It is a pretty cool feature to use Oracle’s SQLDeveper 1.1 to access SQLServer.
The steps are:

  • Download jTDS (open-source SQLServer JDBC driver) from here. Unzip and extract the jtds-1.2.jar or whatever the latest version.
  • Start Oracle’s SQLDeveloper, Tools->Preferences->Database->Third Party JDBC Drivers. Click “Add Entry” and point to the jtds-1.2.jar
  • Create a new connection, choose SQLServer tab, type in hostname, port, username and password. It appears that the initial connection name has to be the same as the database and you can click the “Retrieve database” button. Once you found the database, you can rename the connection.

Try it out.
Of course, certain things don’t work. Like explain plan and auto trace.

Per comments below, please make sure jtds 1.2 is used. Apparently, 1.3 does not work.

    hi there, I am having trouble with this connection. I found the driver and included it, but when creating the connection I get these error:

    Satus: Failure -Network error IOException: Connection refused: connect

    I have tried as many variations as I can think of, including:

    Connection Name: MyDataBaseName
    Username: user
    Password: password
    Hostname: localhost

    Connection Name: MyDataBaseName
    Username: user
    Password: password
    Hostname: localhost/SQLEXPRESS

    Connection Name: MyDataBaseName
    Username: user
    Password: password
    Hostname: localhost

    Obviously I am doing something wrong, I just don´t know what! Any suggestions?
    Thanks in advance

  2. Dong Says:

    I don’t claim to be a sqlserver expert, but did you try the default password? sa/master?

    Also I think the JDBC driver will connect by TCP/IP. Did you configure TCP/IP protocol for SQLServer?

    That’s all I can think of. You can try some SQLServer forum.

  3. treasaigh Says:

    Turning on TCP/IP did the trick… Thanks!

  4. Ramu Says:

    Very helpful, Thanks a lot

  5. kally Says:

    Hi all,

    I have tried all the above possibilities too. BUt could not connect, I am also getting the same exception. I have the tcp/ip enabled and disabled the firewall. May I know whether there is any other possiblity to solve this.

    Thanks in Advance.

  6. DJ Says:


    I am afraid you’ll have to try it the hard way.
    I am not sure how comfortable you are with Java and JDBC. It’ll be fairly straightforward to write a small Java program, using jTDS library to ping your SQLServer db with TCP/IP protocol. If you’re able to, then you eliminate the issue from jTDS side. Then the issue is probably Oracle SQL Developer not recognizing jTDS library, particularly, both have newer versions out since I wrote about it.
    It’s been a while since I last played with Oracle SQL Developer access to SQLServer. I am sorry I cannot of more help.

    Find out which port your SQL Server is listening and may be in your case it is not the default 1433.

    Use this connection setting

    Connection Name: MyDataBaseName
    Username: user
    Password: password

    Thanks, works fine!!! I love Linux but at my work use MS SQL Server, and now I can use my Ubuntu!

  17. naveen Says:

    Hi I am not getting this sql server tab in connection window. i am getting only oracle and access tabs.
    so pls tell me how to get sql server tab.

  18. Matt Corbett Says:

  19. Matt Corbett Says:

    If using SQLEXPRESS put this in the box for port [1433/dbnameyouwantoconnectto;instance=SQLEXPRESS]

  20. sstacha Says:

    I had the same problem as Maria (first post). I finally figured it out from information on the jTDS driver site and thought I would share. If you are using instances (multiple sql servers on the same box) like Maria stated above this is normally referenced by /. However, the jTDS driver was built long before instances and it is a big deal to re-write the parser to add this so instead you have to use a property at the end. To do this you will include a [ ;= ] in the last field of the jdbc string. So, for sql developer in the port field you will put something like [ 1433;instance=SQLExpress ]. This will allow you to populate the database drop down and pick your database.

    Hope this helps someone else out a bit.

    I was using Windows Authentication and had trouble connecting to SQL server, but I read somewhere that if I add domain=thedomainname will connect. I combined it with what I found here in Port: 1433;domain=thedomainname
    That allows Windows Authentication, but I could only view data and no updates. Using SQLDeveloper 3.0.04 and jtds 1.2.5. Anyone can help?

  31. Fred Says:

    1. copy the file ‘jtds-1.2.2-dist\x86\SSO\ntlmauth.dll’ from the unzipped JTDS into \\SQL Developer\jdk\jre\bin.
    2. restart the SQL Developer and that’s it.

    • artexmg Says:

      @Fred …. THAT WORKED!!!

      Only that, in my case, the Path was %INSTALATION_PATH%\sqldeveloper\bin

      and, of course, since i’m usining Win64, I used x64 (duh!)

    Greetings, I think your website might be having web browser compatibility problems. Whenever I look at your site in Safari, it looks fine but when opening in Internet Explorer, it’s got some overlapping issues. I simply wanted to provide you with a quick heads up! Aside from that, great website!

    Hi… after connecting to sql server db using sql developer… i could not see delete row icon under data tab after opening a table.. so please let us know what could be the issue

  40. João Daniel Says:

    Hi! I was trying to connect to a SQL Server with SQL Developer using this 1433;DATABASENAME;instance=SQLEXPRESS syntax but still could not working. I was getting the “Unable to get information from SQL Server” message. So I found on the jTDS faq that I need to enable the SQL Browser service and also enable the TCP/IP connection for my SQL Server. I followed these steps and now it’s OK for me:

    Hope it can help somebody! :-)

    Thanks for all!

  41. Uzair Awan Says:

    I’ve downloaded “jtds-1.3.0″ file from your provided link but after adding the file I am unable to create a new connection because it doesn’t show the dialogue to create a new connection. And when I remove the “jtds-1.3.0″ file it allows me to create a connection but “SQL SERVER” tab is not available there.

  42. oz Says:

    Hello .. I am facing the same issue as Uzair Awan is experiencing. I tried referencing the library both on XP and Vista and none works. Please help. Thanks.

  43. Andy Limbert Says:

    I am having the same issue as Uzair and oz. Anyone else able to correct this issue?

  44. Andy Limbert Says:

    Update: The link at the top of the page takes you to jtds-1.3.0.jar. Need to actually download jtds-1.2.jar from and that seems to work properly.

  45. Brian B Says:

    Can you update your post to point to the 1.2.2 download? The latest version 1.3 doesn’t work and your page comes up in Google. i was going around in circles trying to figure out what I did wrong till I saw the comment about the 1.2 jar being needed.

    I am able to connect to the SQL Server, and also i can view all my elements of this SQL Server instance. But when i drag and drop in the cart, when i click ‘Deploy’ it gives an error ‘The objects are not Oracle Objects’.
    Is there are way to convert SQL Server objects into Oracle Objects.

  48. Mike Hudson Says:

    Blog post has lasted the test of time.. Works perfectly, once I’d added the connection string parameters after port number :)


  49. Berverly Says:

    Having problems connecting to sql database. The server has changed and the hostname is very different. It looks like ABCDEFG09\PA_CMPORT05. Unknown server host name is the message I get when I use this as the hostname and port 1433. Any ideas how to configure with this type of host. I assume the PA_CMPORT05 is an instance name.

  50. Chris Says:

    Man, so many questions here that one wonders if this is actually not that straightforward! When you think about it, a simple 4 field table has 16 permutations, each of which could have something slightly wrong with them. So no wonder everyone’s pulling their hair out here… :((
