sql - doubleが正常に動作しない場合

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"; 

は動作していません。 AND status='Coming Soon'を削除した場合は動作します。

Answer 1

ステータスの映画名とキーと削除別名の

使用backticはなく単一引用符映画-nameは名前ではなく、列の単一使用している場合

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

（これは、問題を作成する可能性があるため）引用リテラル値を選択するが、条件

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