That query assumes that `id` is an explicitly declared rowid. Substitute the name of the rowid of your target table. For example, if your table declaration is thus: ``` create table dingdong ( whapydoodle integer primary key, otherstuffs ); ``` then you would `select max(whapydoodle) from dingdong`. If you do not have an explicitly declared `integer primary key` (rowid) then you would use whatever alias for the rowid is available that has not been declared as a column in your table: `rowid`, `_rowid_`, or `oid`. See the fine documentation: <https://sqlite.org/c3ref/last_insert_rowid.html>
