mysql查詢返回列名

我有一個導出爲CSV文件的MySQL查詢。收到CSV的人要求我添加列標題。很顯然，我可以在查詢中硬編碼它們，但是想知道是否有辦法返回一個包含所有已查詢列的名稱的行？mysql查詢返回列名

我目前的查詢如下 - 我希望以編程方式包含列標題，如果我可以只是萬一我忘記更改它時進行更改。

感謝

您可以使用union;）在第一行返回列名稱 – 2014-09-03 16:54:54

這可能有助於[如何將表列標題添加到sql select語句]（http://stackoverflow.com/questions/4964162/how-to -add-表列標題到SQL-select語句） – Dan 2014-09-03 16:55:16

登錄電子，因爲它是另一種方式來解決問題：

從dual UNION中選擇'col_1'，'col_2'，'col_3'，'col_4'全部從table_1中選擇 col_1，col_2，col_3，col_4;

這是一個奇怪的問題:)嘗試

SELECT 
    * 
FROM 
    information_schema.COLUMNS 
where 
    table_chema = 'your_schema' 
     and table_name = 'your_table';

不是使用ORDINAL_POSITION這分別顯示相關的列名
