| 00:26 | Add new interfaces sqlite3_value_subtype() and sqlite3_result_subtype(). Update the json1.c extension to take advantages of those interfaces to avoid the goofy '$$' path syntax and to allow nested calls to json_array() and json_object() that work as expected. check-in: db4152ae user: drh tags: trunk | |
