when I set the option upper_needs_cast as Yes.It only takes effect on id_query when adding an entry,but does not take effect on child id query when deleting an entry.

I found that in the src file back-sql/init.c

line 374 --379

there are not operation about upper cast.

I want to know if what I think is right.

Not clear what's your point. "upper_needs_cast" is a hack to work around the fact that some RDBMSes need an explicit cast before passing a literal into whatever "uppercase" function they provide.

Can you point out what's the problem and what's the expected behavior? I don't see any literal passed to the query that looks up the parent's and that needs any special treatment.

A log of the offending operation, and an example of what you'd consider correct, would help.
