SQL中的错误（SELECT和LEFT Join）如何给id第一个表？

Question

我有sql select：

SELECT * 
FROM `fclients` AS F 
LEFT JOIN `fclients_sequens` AS FS ON F.category = FS.category 
ORDER by FS.num

我得到了结果：

result select sql http://i066.radikal.ru/1210/15/fa9c91a9d6b2.jpg

然后，对于第一个表中的给定id，我进行sql查询：

SELECT *, fclients.id as fclientsID 
FROM `fclients` AS F 
LEFT JOIN `fclients_sequens` AS FS ON F.category = FS.category 
ORDER by FS.num

我收到错误：

  

＃1054 - “字段列表”中的未知列'fclients.id'

请告诉我如何给id拳栏（id = 37）？

Answer 1

引用列ID

时，需要使用别名F.

SELECT *, F.id...
