对于MySQL 5.7版本，可以使用sys.session视图来查看会话最后一次执行的SQL：

SELECT *FROM sys.session

WHERE CONN_ID= 20036 \G

其中sys.session视图关联到sys.processlist，而sys.processlist又使用到`performance_schema`.`events_statements_current`。

如果想查询某个会话从开启到现在的执行过的SQL情况，就需要使用到下列表：

performance_schema.events_statements_current

performance_schema.events_statements_history

performance_schema.events_transactions_history_long

上面三张表中记录MySQL服务器最近执行过的SQL情况，但上面三张表中的表示时间的字段使用皮秒来表示，且不能直接使用FROM_UNIXTIME来转换(不是以1970-01-01 00:00 或 0000-01-01 00:00为起点， 每个MySQL实例的起始基线不同)。

使用下面脚本可以查看到特定会话上的SQL执行情况：

SELECT @dt_ts:=UNIX_TIMESTAMP(NOW());SELECT

@dt_timer:=MAX(SH.TIMER_START)FROM performance_schema.threads AST1INNER JOIN performance_schema.events_statements_history ASSHON T1.`THREAD_ID`=SH.`THREAD_ID`WHERE T1.PROCESSLIST_ID=CONNECTION_ID();SELECTSH.`SQL_TEXT`,

FROM_UNIXTIME(@dt_ts-CAST((@dt_timer-SH.TIMER_START)/1000000000000 AS SIGNED)) ASstart_time,

FROM_UNIXTIME(@dt_ts-CAST((@dt_timer+SH.TIMER_END)/1000000000000 AS SIGNED)) ASend_time,

(SH.TIMER_END-SH.TIMER_START)/1000000000000 ASused_seconds,

SH.ROWS_AFFECTEDASaffected_rows,

SH.ROWS_SENTASsend_rowsFROM performance_schema.threads AST1INNER JOIN performance_schema.events_statements_history ASSHON T1.`THREAD_ID`=SH.`THREAD_ID`WHERE T1.PROCESSLIST_ID=946364

AND SH.TIMER_START

ORDER BY SH.TIMER_START ASC;

输出效果如下：

+------------------------------------+---------------------+---------------------+--------------+---------------+-----------+

| SQL_TEXT | start_time | end_time | used_seconds | affected_rows | send_rows |

+------------------------------------+---------------------+---------------------+--------------+---------------+-----------+

| select sleep(5) | 2019-07-29 19:59:55 | 2019-07-29 20:00:00 | 5.0003 | 0 | 1 |

| insert into tb001(c1,c2)select 2,4 | 2019-07-29 20:01:26 | 2019-07-29 20:01:26 | 0.0002 | 1 | 0 |

| insert into tb001(c1,c2)select 2,4 | 2019-07-29 20:04:34 | 2019-07-29 20:04:34 | 0.0001 | 1 | 0 |
