Wouldn't the addition of "Empty result sets will return SQLITE_DONE on the first call to sqlite3_step." add some clarity?

Yes. > If that is the case, might that be added to the documentation? "SQLITE_DONE means that the statement has finished executing successfully." "If the SQL statement being executed returns any data, then SQLITE_ROW is returned each time a new row of data is ready for processing by the caller." The implication is that if SQL statement doesn't return any data, then sqlite3_step doesn't return SQLITE_ROW. Since it nevertheless finishes executing successfully, it returns SQLITE_DONE. -- Igor Tandetnik _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
