That’s a partial ordering though, based on a dependency graph. You’d want to maintain the dependencies in the database as the ground truth, and when needed generate a topological ordering based on the dependencies. That can be maintained in some kind of cache table, but it’s not something that you would need to dynamically update like the OP but rather regenerate it when the dependencies change. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
