Using SQL Developer to connect to SQL Server databases

Apparently, being able to use Oracle s SQL Developer to connect to SQL Server databases has been around for a while (via third party drivers), but I only started using it today for the first time, with SQL Developer 4 EA2 after my colleague mentioned it to me this afternoon

First of all, thanks to DJ s blog here as a base for the instructions that follow. Here s how you can set this up:

  1. Download the jTDS 3rd party JDBC driver, version 1.2.8 from here (I ve not personally tested with other versions).
  2. Save and extract the contents of the file somewhere safe (I extracted mine under C:\oracle\sqldeveloper\add-ons\jtds-1.2.8-dist\ ).
  3. Start SQL Developer go to Tools Preferences Database Third Party JDBC Drivers.
  4. Click “Add Entry”, point to the jtds-1.2.8.jar file location, then select it and click OK.
  5. Create a new connection, and choose the SQLServer tab.
  6. Enter the following details: Connection Name (required for database retrieval), Username, Password, Hostname, and Port.
  7. Click Retrieve database and select the appropriate database, then Save/Test/Connect as you would do normally.

You ll notice from the screen shot above that you can also use this to connect to Sybase databases, although I ve not tried this out myself.

UPDATE: If you at any point decide to use Windows authentication to connect (like I just did), then you might hit this error:

Status. Failure -I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.

…I quickly found a work around, which involved copying the ..\jtds-1.2\x64\SSO\ntlmauth.dll file from the jTDS directory to the %JAVA_HOME%\jre\bin folder. Then I restarted SQL Developer and it all worked fine

This works, but unfortunately there are a number of shortcomings. Some key words used in T-SQL and SQL Server scripts like GO and EXEC don t play nicely with Oracle SQL Developer. Also issues with Stored procs that return multiple result sets etc. It really depends on your environment, but if you re dealing with a lot of large scripts that were written in T-SQL you ll find issues.

Thanks for the heads up I never really spent too much time using SQL Developer for managing SQL Server (defaulted to using SSMS), so that s good to know. Hopefully the development team will pick up on such issues and fix in later releases though
