如何在mysql中自定义show processlist？
我想按时间sorting，但似乎没有办法做到这一点？

49 rows in set (0.00 sec) 较新版本的SQL支持information_schema中的进程列表：
SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST
你可以用任何你喜欢的方式来订购。
INFORMATION_SCHEMA.PROCESSLIST表是在MySQL 5.1.7中添加的。 你可以找出你正在使用的版本：
SELECT VERSION()
命令
show full processlist
可以replace为：
SELECT * FROM information_schema.processlist
但如果你使用后者的版本，你可以添加WHERE子句：
SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';
欲了解更多信息， 请访问
另一个有用的命令行界面工具是pager命令。
例如
pager grep -v Sleep | more; show full processlist;
然后，您可以翻阅结果。
您也可以通过这种方式使用grep或sed查找某些用户，IP或查询。
分页命令每个会话都是持久的。
您可以捕获输出并通过filter传递，如下所示：
mysql show processlist | grep -v '^\+\-\-' | grep -v '^| Id' | sort -n -k12
两个greps删除标题和预告片行（如果有其他行不包含有用的信息可能需要其他人），sorting是根据数字字段编号12（我认为是正确的）完成。
这一个适用于你的直接输出：
mysql show processlist | grep -v '^\+\-\-' | grep -v '^| Id' | grep -v '^[0-9][0-9]* rows in set ' | grep -v '^ ' | sort -n -k12
如果你使用旧版本的MySQL，你总是可以使用\ P结合一些不错的awk代码。 这里有趣的例子

这不正是你所需要的吗？
…我们还没有更新版本的MySQL，所以我能够做到这一点（仅适用于UNIX）：
host=maindb echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked
以上将查询所有locking的会话，并返回涉及的信息和SQL。
…所以 – 假设你想查询正在睡觉的会话：
host=maindb echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep
或者，假设您需要为MySQL提供其他连接参数：
host=maindb user=me password=mycoolpassword echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked
通过一些调整，我确定可以很容易地创build一个shell脚本来以你想要的方式查询processlist。
