Have you looked at just directly using the GdaQuery objects? You can constuct an abstract query out of GdaQueryFieldFields, GdaQueryFieldValues and such. Then, libgda will emit the provider-specific SQL for that query. To be frank, IMO, GdaQuery is a better data model for queries than QofQuery. By "better", I mean "more appropriate for GnuCash". I think it's very unfortunate that GnuCash uses its own home-grown object-agnostic query representation. Someone else will probably disagree. But, if you re-parented GnuCash's engine objects with a GnuCash-sepcific GncObject (even with GValue parameters, maybe), and implemented the QofQuery functionality by generating a GdaQuery, you would be my hero. But that's probably more work than you were hoping for. *sigh* Anyway, try to avoid writing the SQL emitter, if you can. -chris _______________________________________________ gnucash-devel mailing list gnucash-devel@gnucash.org https://lists.gnucash.org/mailman/listinfo/gnucash-devel
