Hi, I have a without rowid virtual table with an implementation of xColumn that begins with
if(sqlite3_vtab_nochange(ctx)) return SQLITE_OK; If I try to perform an update on this table that doesn't involve a primary key change, then my understanding from the documentation is that xUpdate will be called and the value of argv[0] and argv[1] will be the same. What I am seeing is that argv[1] is set an sql null value, although when I call sqlite3_value_nochange(argv[1]) I do get true returned. Am I therefore right in thinking that the correct detection of whether there is an update without a primary key change when using sqlite3_vtab_nochange is actually sqlite3_value_nochange(argv[1]) || values_are_equal(argv[0], argv[1]) Thanks, Kev _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
