sql - double條件不起作用

Question

$sql3 = "SELECT DISTINCT id as id,status as status,'movie-name' as 'key', 
moviename as value,poster as cover 
FROM movie 
WHERE id='$movieid' AND status='Coming Soon' 
ORDER BY id DESC LIMIT 6"; 

似乎不起作用。如果我刪除AND status='Coming Soon'它的作品。

Answer 1

使用backtic，而不是單引號的電影名稱和鍵和刪除別名狀態，如果電影的名字是一個名稱，而不是列使用單一的（因爲這可能造成在問題）

$sql3 = "SELECT DISTINCT id ,status ,`movie-name` as `key`, 
      moviename as value,poster as cover 
      FROM movie 
      WHERE id='$movieid' 
      AND status='Coming Soon' 
      ORDER BY id DESC 
      LIMIT 6"; 

報價爲選擇的字面意義，但記得在條件

$sql3 = "SELECT DISTINCT id ,status ,'movie-name' as `key`, 
      moviename as value,poster as cover 
      FROM movie 
      WHERE id='$movieid' 
      AND status='Coming Soon' 
      ORDER BY id DESC 
      LIMIT 6";
