All true, but irrelevant is the *purpose* of this constant is not what you want it to be. As I read the docs, the only purpose of this constant is so that SQLite can give an error if you use a non-deterministic function anywhere that would cause DB corruption. That is all. Could it be *extended* to mean what you want? Of course, but that means you’re asking for a feature, not reporting a bug. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
