Re: [hibernate-dev] Difference between Comment and Hint in Hibernate query

HI, I think I'll have to make it a little bit more clear in the docs as well. I Knew about Hibernate comments and assumed they could be used as hints. Now, that I look back on the Query API I see they were added in 4.3:

Re: [hibernate-dev] Difference between Comment and Hint in Hibernate query

I created a new Pull Request so that comments can be handled for named queries (even for UPDATE/DELETE queries): https://github.com/hibernate/hibernate-orm/pull/1970 I think we should add two new issues; 1. So that we could pass Query Hints for Named (Native) Queries as well. Right now we can

Re: [hibernate-dev] Difference between Comment and Hint in Hibernate query

Re: [hibernate-dev] Difference between Comment and Hint in Hibernate query

They have different intentions and are potentially applied in different ways for different databases - hence separate. E.g. DB2 supports a query comment, but does not support optimizer hints... so these need to be handled differently On Tue, Aug 1, 2017, 8:19 AM Vlad Mihalcea

[hibernate-dev] Difference between Comment and Hint in Hibernate query

Re: [hibernate-dev] PESSIMISTIC_FORCE_INCREMENT lock mode

Actually the spec is quite specific on the expected behavior of these lock modes, although it is very detailed and verbose almost to the point of being unclear. Also it is confusing to think of this in terms of generalized concepts such as "exclusive" versus "non-exclusive". Database locking
