Sadly, this isn't sufficient for guarding against malformed dates like '2019-02-00' and '2019-02-1' that the OP listed, because the CHECK expression in those cases resolves to NULL, which does *not* signal a constraint violation. Instead, you have to "round-trip" the date conversion manually, and check that the intermediate Julian conversion IS NOT NULL, for this CHECK to be truly effective. -- Best Regards, Adrian _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
