Thomas Mueller commented on HHH-3401:
-------------------------------------
Hi Chris,
we're missing some coverage
Yes, it looks like.
Certainly the 3.3 testsuite covers this
Yes, but the testsuite doesn't seem to test 'reloading'. It is probably
possible to test this feature, but I'm not familiar with the Hibernate test suite. If
you want me to write a better test case then it would take some more time I'm
afraid...
why vendors that maintain/contribute Dialects just don't ship
them
The dialect is included in H2 under h2/src/tools/org/hibernate/dialect/H2Dialect.java.txt
(I renamed it to .txt so that I don't have to add a dependency to Hibernate). I could
include the class file in the h2*.jar, but that would not help if the Hibernate jar file
is loaded first. Also, writing a dialect that works with all versions of Hibernate could
be hard.
Regards,
Thomas
H2 Database Dialect Fixes
-------------------------
Key: HHH-3401
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3401
Project: Hibernate Core
Issue Type: Bug
Components: core
Reporter: Thomas Mueller
Assignee: Chris Bredesen
Attachments: H2Dialect.java, H2Dialect.java.patch, test.zip
There are a few bugs in the H2 Dialect:
- There is no native BIT data type in H2.
- The database function DATEDIFF does have parameters
- There is a typo in function QUARTER
I have created a patch and a simple test case: The problem with the BIT / BOOLEAN data
type appears if you run the test twice. Please tell me if you need more information.
Regards,
Thomas
