我正在創建一個 crud 應用程序，并且正在使用內存數據庫測試數據庫。唯一中斷的測試和函數是 toggleTask 函數和測試。功能：func (r *Repository) ToggleTask(task Task) (Task, error) {    query := "UPDATE Tasks SET completed = NOT completed WHERE id = (?)"    _, err := r.db.Exec(query, task.ID)    if err != nil {        return task, err    }    query = "SELECT id, txt, completed FROM Tasks WHERE id = (?) RETURNING *"    err = r.db.QueryRow(query, task.ID).Scan(&task.ID, &task.Text, &task.ListID, &task.Completed)    if err != nil {        return task, err    }    return task, nil}測試：const (    ToggleTask = "SELECT id, txt, completed FROM Tasks WHERE id = (?) RETURNING *")func TestToggleTask(t *testing.T) {    repo := mockDbRepo()    list := List{Name: "Test List"}    repo.db.Exec(CreateList, list.Name)    task := Task{Text: "Test Task", ListID: list.ID}    repo.db.Exec(CreateTask, task.Text, task.ListID)    completedTask,err := repo.ToggleTask(task)    if err != nil {        t.Error(err)    }    if !reflect.DeepEqual(completedTask, task) {        t.Errorf("Expected %v, got %v", task, completedTask)    }}測試返回給我：SQL 邏輯錯誤：“RETURNING”附近：語法錯誤 (1)
