我有一个像这样的 HQL 查询：
Select
... (around 40 items)...
from
ATable a
left outer join a.subA SubA
left outer join a.subB SubB
left outer join a.Names Names
left outer join Names.Addresses Addresses
left outer join Names.Phones Phones
left outer join a.Roles Roles
where
a.aType.someType in ('...')
and (Names.id.FKey in('...') or Names.id.FKey is null)
and upper(a.pin) like upper('some%')
and upper(Names.lastName) like upper('Some%')
order by a.pin asc
由于某种原因，这会超时，但使用 Toad 时由 hibernate 生成的查询（取自日志）需要 5 秒才能执行。我是hibernate的新手。我感谢任何帮助优化此谢谢。
