[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2647) Problems with OR parenthesis in HQL
[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2647?page=c...
]
Paizo commented on HHH-2647:
----------------------------
No, it's not consistent.
Example:
HQL:
from d.defects.def8715.lim.bl.pom.impl.PContainer p where ( p.i = ?) and ( ( p.entityId
.class$ <> ?) or ( p.entityId .ser$ <> ?)) and ( p.i = ?)
SQL (omitting select and from for readability):
where pcontainer0_.c_i_818c4=? and pcontainer0_.class$_entit_1f106<>? or
pcontainer0_.ser$_entityI_1f106<>? and pcontainer0_.c_i_818c4=?
This is an awesome bug :D i tried to workaround this problem
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5886 explicity using
component's field.
So it seems that the workaround of the workaround is to convert the 'or' using
'NOT'

Given the following (part) of a query in HQL (where 1 to 6 are comparisons of different
types (=, <=, is null), but irrelevant for the problem posted here ):
AND ( ( 1 AND 2 ) OR ( 3 AND 4 ) OR ( 5 AND 6 ) )
will be balanced to:
and ( ( 1 ) and 2 or 3 and ( 4 ) or 5 and 6 )
