こんにちは、データベースにタイム シート ビューを作成しようとしましたが、admin_id 列に問題があります。機能する別の割り当てからこのコードを再利用しているので、なぜ機能しないのか混乱しています。私を助けてください!!!
ステートメントを選択
SELECT timesheet_id, class, day, hour, week, admin_id, date_added FROM timesheet, day, classes, admin
WHERE timesheet_id AND
classes.class_id = timesheet.class_id AND
day.day_id = timesheet.day_id AND
admin.admin_id = timesheet.admin_id ORDER BY timesheet.timesheet_id.;
