Hey Jiri,
Stanislav Muhametsin a écrit :
The whole persistence aspect of Qi4j (EntityStore + Indexing) has
implementation for SQL. The code is a bit outdated, and probably could
be optimized a lot with some effort, though. I hope I will get time to
at least fix the Indexing-SQL for next release so that it would pass
tests.
To be more precise, indexing-sql miss AssociationNotNullSpecification &
PropertyNotNullSpecification handling. Theses predicates were added in
Qi4j 2.0.
It means that you can use indexing-sql today but until Stan find time to
fix this you'll miss support for QueryExpressions.notNull(...) from the
Query API.
Workaround is to use not( isNull( .. ) ) for now.
/Paul
