I would have expected hibernate to use quoted identifier when creating the table.

Any ideas on how to handle this... other than renaming the field?

Had the same problem, but with a tablename called Transaction. If you set

hibernate.globally_quoted_identifiers=true

Then all database identifiers will be quoted.

Found my answer here Special character in table name hibernate giving error

And found all available settings here https://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/appendices/Configurations.html

Could not find better docs for this though.

In my case the setting was in my Spring properties file. As mentioned in the comments, it could also be in other, hibernate related, configuration files.

  • See e.g. hibernate.onjira.com/browse/HHH-1272
  • How is this not the default setting?
  • SQL might become unreadable and using keywords as names is a bad practice that should not be encouraged. I think...?
  • Okay. I'll prefer an escaped reserved word as a name all day long over a name that doesn't fit.
  • Yes, you could say that the abstraction provided by Hibernate is only of concern and not how it is technically implemented. But if you also use tooling like Flyway or Liquibase, then it adds to complexity when you need to consider that there might be reserved words. This has been my experience when migrating schema's.
  • For those wondering where this needs to be set, it's probably in your persistence.xml for JBoss projects.
  • And thanks from me. It solved a problem I had. btw - Ref is now at: docs.jboss.org/hibernate/stable/core/manual/en-US/html/…
  • I don't understand why I have to do this, why Hibernate don't do this automatically instead of me???
  • @DanielHári maybe you find my answer more "automatic"?
  • @Rafiek: Oh yes, that's the perfect solution, upvoted (y).
  • Using @Column(name="[open]") is much prettier :)
  • You're just doing this on the private field not on the getter?
  • this is sqlserver specific.
  • That may work. See stackoverflow.com/questions/285775/…. Let's wait for the OP confirmation.
