Oracle SQL Developer and a SQL Server Instance

Sometimes… as Oracle DBA you need to connect to SQL Server (with Oracle SQL Developer and jTDS plug-in installed).

When using ‘SQL Server Management Studio’, the ‘Server name’ is in the format:


This won’t work in SQL Developer:

Status : Failure -Unknown server host name 'SERVERNAME\INSTANCE'.

This can be solved using the ‘hostname’ in the next format in SQL Developer:


For me it worked :)

    Thanks a lot. This worked for me as well but when i connect its loading all the database in the server without database objects except users(no tables, procedures, functions etc.). Can you give the solution.

      I’m not sure… I actually did this only once of twice.
      It sounds a bit like if you don’t have the rights to show database objects.
      Users are not part of the databases in SQL Server if I remember correctly.
      Not the latest version of SQL Developer of a very new version of SQL Server perhaps?
      Sorry that I can’t help you further with this.

      Regards, Ian.
