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 | COUNT_STAR | +---------------------------------------------------------------------------------------+------------+ | stage/sql/After create | 0 | | stage/sql/allocating local table | 0 | | stage/sql/preparing for alter table | 0 | | stage/sql/altering table | 0 | | stage/sql/committing alter table to storage engine | 0 | | stage/sql/Changing master | 0 | | stage/sql/Checking master version | 0 | | stage/sql/checking permissions | 0 | | stage/sql/checking privileges on cached query | 0 | | stage/sql/checking query cache for query | 0 | | stage/sql/cleaning up | 0 | | stage/sql/closing tables | 0 | | stage/sql/Connecting to master | 0 | | stage/sql/converting HEAP to MyISAM | 0 | | stage/sql/Copying to group table | 0 | | stage/sql/Copying to tmp table | 0 | | stage/sql/copy to tmp table | 0 | | stage/sql/Creating delayed handler | 0 | | stage/sql/waiting for delay_list | 0 | | stage/sql/waiting for handler insert | 0 | | stage/sql/waiting for handler lock | 0 | | stage/sql/waiting for handler open | 0 | | stage/sql/Waiting for INSERT | 0 | | stage/sql/Waiting for master to send event | 0 | | stage/sql/Waiting for master update | 0 | | stage/sql/Waiting for slave mutex on exit | 0 | | stage/sql/Waiting for slave thread to start | 0 | | stage/sql/Waiting for table flush | 0 | | stage/sql/Waiting for query cache lock | 0 | | stage/sql/Waiting for the next event in relay log | 0 | | stage/sql/Waiting for the slave SQL thread to advance position | 0 | | stage/sql/Waiting to finalize termination | 0 | | stage/sql/Waiting to get readlock | 0 | | stage/mysys/Waiting for table level lock | 0 | | stage/sql/Waiting on empty queue | 0 | | stage/sql/Waiting for next activation | 0 | | stage/sql/Waiting for the scheduler to stop | 0 | | stage/sql/Waiting for global read lock | 0 | | stage/sql/Waiting for schema metadata lock | 0 | | stage/sql/Waiting for table metadata lock | 0 | | stage/sql/Waiting for stored function metadata lock | 0 | | stage/sql/Waiting for stored procedure metadata lock | 0 | | stage/sql/Waiting for trigger metadata lock | 0 | | stage/sql/Waiting for event metadata lock | 0 | | stage/sql/Waiting for commit lock | 0 | +---------------------------------------------------------------------------------------+------------+ 108 rows in set (0.00 sec)
使用select 列出所有的字段，比如select "Col1","Col2".... union all
(root@localhost) [test]>select "EVENT_NAME","COUNT_STAR" -> union all -> SELECT EVENT_NAME ,COUNT_STAR from events_stages_summary_global_by_event_name; +---------------------------------------------------------------------------------------+------------+ | EVENT_NAME | COUNT_STAR | +---------------------------------------------------------------------------------------+------------+ | EVENT_NAME | COUNT_STAR | | stage/sql/After create | 0 | | stage/sql/allocating local table | 0 | | stage/sql/preparing for alter table | 0 | | stage/sql/altering table | 0 | | stage/sql/committing alter table to storage engine | 0 | | stage/sql/Changing master | 0 | | stage/sql/Checking master version | 0 | | stage/sql/checking permissions | 0 | | stage/sql/checking privileges on cached query | 0 | | stage/sql/checking query cache for query | 0 | | stage/sql/cleaning up | 0 | | stage/sql/closing tables | 0 | | stage/sql/Connecting to master | 0 | | stage/sql/Waiting for table metadata lock | 0 | | stage/sql/Waiting for stored function metadata lock | 0 | | stage/sql/Waiting for stored procedure metadata lock | 0 | | stage/sql/Waiting for trigger metadata lock | 0 | | stage/sql/Waiting for event metadata lock | 0 | | stage/sql/Waiting for commit lock | 0 | +---------------------------------------------------------------------------------------+------------+ 109 rows in set (0.00 sec)
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
