SQL錯誤/排序打破PHP

Question

我的第一次聲明中的偉大工程，但我想訂購的聲明，並取回由[meta_value]

SELECT * FROM wp_postmeta WHERE meta_key = "win_percentage" 
Array 
(
    [0] => stdClass Object 
     (
      [meta_id] => 417 
      [post_id] => 59 
      [meta_key] => win_percentage 
      [meta_value] => 9.3023255814 
     ) 

    [1] => stdClass Object 
     (
      [meta_id] => 419 
      [post_id] => 62 
      [meta_key] => win_percentage 
      [meta_value] => 6.66666666667 
     ) 

) 

SELECT * FROM wp_postmeta WHERE meta_key = "win_percentage" ORDER BY = meta_value ASC 

失敗

Answer 1

後刪除=最高比例1的結果ORDER BY

SELECT * FROM wp_postmeta WHERE meta_key = "win_percentage" ORDER BY meta_value ASC 

讀http://dev.mysql.com/doc/refman/5.7/en/order-by-optimization.html

Answer 2

ü se ORDER BY {COLUMN_NAME}不使用=與秩序通過。

SELECT * FROM wp_postmeta WHERE meta_key = "win_percentage" ORDER BY meta_value ASC
