Connect to Snowflake with JDBC

As promised in my earlier post, here is a deeper dive into the next of the Top 10 Cool Features from Snowflake:

#9 Ability to connect with JDBC

This seems like a no brainer but is very important. If you’re interested in connecting any custom or packaged Java based applications to Snowflake, JDBC is what you need. JDBC technology lets you access information in SQL databases using standard SQL queries.

So why is this cool? Because all of the modern applications written in Java can take advantage of our elastic cloud based data warehouse through a JDBC connection.

And we have plenty of customers doing that today with industry leading tools.

Tech Tip: Connect to SQL Server Using Oracle SQL Developer (updated)

I spend a lot of time reverse engineering client databases to see what kind of design they are working with or to simply create a data model diagram for them (so they know what they have).

Along the way I often need to actually look at the data as well to do some analysis and profiling.

Often this means looking at data and models in SQL Server as well as Oracle.

What’s an Oracle Data Warrior to do?

Hook up my FREE handy dandy Oracle SQL Developer to the SQL Server database.

How do you do that?

First you need to get the right driver. You can find it here: http://sourceforge.net/projects/jtds/files/jtds/1.2.5/jtds-1.2.5-dist.zip/download

NOTE: For SQL Developer 4.0EA3 and SQL Developer Data Modeler 4.0 (production) you now need jtds-1.3.1. Get it here: http://sourceforge.net/projects/jtds/files/

Then follow these steps:

  1. Download and unzip the file into the main SQL Developer directory (or the directory of your choice).
  2. In SQL Developer go to Tools -> Preferences -> Database -> Third party JDBC Drivers
  3. Click the “add entry” button
  4. Navigate to the jtds-1.2.5.jar file. (or the 1.3.1 file for 4.x installs)
  5. Save and exit preferences.
  6. Close and restart SQL Developer
  7. Open “Add Connection” – there should now be a SQL Server tab.

With this in place, you can now connect to SQL Server without having to load any other software.

Pretty useful.

Happy Querying!

P.S. You can connect to other non-Oracle dbs as well. Check out this post by Jeff Smith for even more details.

Additional Notes on SSO errors:

Lots of folks, including me, have had issues getting the native Windows SSO connection to SQL Server to work. Based on answers on the OTN Forum and this post (http://www.oracle-base.com/blog/2013/10/01/sql-developer-4-ea2-connecting-to-sql-server/) I finally got my new 4.x versions to work.

For SQL Developer 4.0EA3, I did as suggested in the article: http://www.oracle-base.com/blog/2013/10/01/sql-developer-4-ea2-connecting-to-sql-server/. I put the ntlmauth.dll where my JDK 1.7 was installed: C:\Program Files\Java\jdk1.7.0_40\jre\bin

For Data Modeler 4.0.13 (production), based on a suggestion from Jeff Smith, I put the dll file here: C:\SQLDeveloper\SQLDeveloper4.0.13\sqldeveloper\sqldeveloper\bin

If I was better at setting windows paths, I am sure there is a better way to do this.
