我的第一次声明中的伟大工程，但我想订购的声明，并取回由[meta_value]SQL错误/排序打破PHP

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

失败

WordPress数据库错误：[您的SQL语法错误;请检查与您的MySQL服务器版本对应的手册，以在第1行'='meta_value“ASC'附近使用正确的语法] SELECT * FROM wp_postmeta WHERE meta_key =”win_percentage“ORDER BY =”meta_value“ASC –

后删除=最高比例1的结果ORDER BY

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

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

ü se ORDER BY {COLUMN_NAME}不使用=与秩序通过。

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