通過傳遞一些常量字符串變量

Question

比方說，我的數據庫表結構就像導出到CSV文件，從數據庫：

he  haddress hage she  saddress  sage 
Sam  USA 25 Jenny  germany  21 
John  UK  32 Anne  france  29 
keith USA 27 nicole  france  21 

我想導出這個aboce結果使用此命令設置成csv文件：

select he, haddress, hage, she, saddress, sage into outfile '/tmp/test1.csv' 
fields terminated by ',' 
lines terminated by '\n' from table_name; 

它創建的CSV文件格式如下：

Sam,USA,25,Jenny,germany,21 
John,UK,32,Anne,france,29 
keith,USA,27,nicole,france,21 

現在我想在上面如下：

Sam,address,USA,age,25,knows,Jenny,address,germany,age,21 
..... 
..... 
..... 

如何在生成csv文件時傳遞這些字符串。
