我想按时间订购，但似乎没有办法？

较新版本的SQL支持information_schema中的进程列表：

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST

您可以按照自己喜欢的任何方式订购。

在MySQL 5.1.7中添加了INFORMATION_SCHEMA.PROCESSLIST表。您可以找出正在使用的版本：

SELECT VERSION()

太好了，但与之相同show full processlist，例如，该INFO部分完整，是否有简短版本？或者我需要使用substr

@肖尔：你想做些什么吗？

命令

show full processlist

可以替换为：

SELECT * FROM information_schema.processlist

但是，如果您使用的是后者版本，则可以在其中添加WHERE子句：

SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';

从命令行界面执行此操作的另一个有用工具是寻呼机命令。

例如

pager grep -v Sleep | more; show full processlist;

然后，您可以浏览结果。

您也可以通过grep或sed查找某些用户，IP或查询。

寻呼机命令在每个会话中都是持久的。

您可以只捕获输出并将其通过过滤器，例如：

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | sort -n -k12

这两个粗线会除去标题行和尾部行（如果还有其他行不包含有用信息，则可能需要其他行），并且排序是基于数字字段编号12进行的（我认为是正确的）。

这一项适用于您的直接输出：

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | grep -v  '^[0-9][0-9]* rows in set '
    | grep -v '^ '
    | sort -n -k12

您无需grep连续打四遍电话；sed就像这样使用：sed '/^\+\-\-/d; /^| Id/d; /^[0-9][0-9]* rows in set '/d; /^ /d;一次调用一个程序（不是四个），它更快，更干净，更简单，并且运行也更快。

您不需要，不，但是可以。如果您想每秒执行很多次这样的事情，那么可以，请担心性能。否则，这不是问题，特别是考虑到数据集的大小。

如果您使用旧版本的MySQL，则可以始终将\ P与一些不错的awk代码结合使用。这里有趣的例子

正是您所需要的吗？

...我们还没有MySQL的较新版本，因此我能够做到这一点（仅适用于UNIX）：

 host=maindb

 echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked

上面将查询所有锁定的会话，并返回所涉及的信息和SQL。

...所以-假设您想查询正在休眠的会话：

  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，我确信可以轻松创建Shell脚本来以所需方式查询进程列表。
