The Hibernate ORM and SQL Server

  • You can try the attached SqlCleaner. It was written a few years ago and definitely depends on the command starting with exec sp_executesql N'SELECT yada yada

    and ending with something like this:

  • This was basically my introduction to SQL. Doing Tech Support for an app build on Java using Hibernate. It was a small team with a couple of developers and no DBAs on the team. Our software was use was mixed with some of it being in hosted in house on MS-SQL servers with others being hosted by our customers with most of those using Oracle. Definitely saw some of the things discussed in here but luckily for us Hibernate hadn't started falling down completely or gotten two bad performance wise because our data was still pretty small. Typically our large databases only got up into the teens of gbs with only a couple tables getting big. We even did several of the things on the list of things not to do like using the built in caching and thread pools. I'm sure a good team with the right people who really knew what they are doing could completely rebuild the app and make it so much better but that is just a dream and not my problem anymore 😀
