如何在select into outfile 的文件中显示column name

正常情况先select into outfile 生产的文件是不包含column name，比如如下sql

(root@localhost) [test]>SELECT EVENT_NAME ,COUNT_STAR from events_stages_summary_global_by_event_name;+---------------------------------------------------------------------------------------+------------+| EVENT_NAME

使用select 列出所有的字段，比如select "Col1","Col2".... union all

或者直接使用mysql -e > a.log 的方式来实现

mysql -u gf -p test -e "SELECT EVENT_NAME ,COUNT_STAR from events_stages_summary_global_by_event_name" > /home/mysql/event2.dat
