Hibernate HQL to basic SQL
- by CC
Hello everybody,
I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff.
The idea is that the project is big enough, and we have many HQL queries.
The problem is with the queries like
select a,b from table1, table2 on t1.table1=t2.table2
Basically all joins are not supported by our "hand made persistence" stuff.
What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but the basic SQL without joins, something like (a dumb example)
select a from table1
where t1 IN (
select b from table2)
I hope you get the idea.
My persistence layer does not supports joins.
Does anybody has any idea about something like that?
Some framework, or something?
Thanks alot everybody.
C.C.
