标签: processlist

我mysql从我的Linux shell 连接到.我不时地运行一个SELECT太大的查询.它打印和打印,我已经知道这不是我的意思.我想停止查询.

击中Ctrl+C(几次)mysql完全杀死并带我回到外壳,所以我必须重新连接.

是否可以在不自杀的情况下停止查询mysql？

我想按时间排序,但似乎无法做到这一点？

mysql> show processlist;

当我在MySQL数据库中运行SHOW PROCESSLIST时,我得到了这个输出:

mysql> show full processlist;

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

我想知道命令下的"睡眠"过程.这是什么意思？为什么它长时间运行并显示NULL？它使数据库变慢,当我终止进程时,它正常工作.请帮我.

如何从Unix获取所有正在运行的进程的进程列表,包含命令/进程名称和进程ID,因此我可以过滤和终止进程.

我有一个脚本运行一批非常相似的查询。
所有这些，除了一个，运行没有任何问题。
只有一个查询卡住了。
在“show processlist”中，查询有 state=null
根据文档，show processlist 应该只为“show processlist”线程本身报告“State=null”。

当我show processlist在mysql中做的时候,我得到了进程列表.其中一个进程是binlog dump从quit运行很长时间.
什么是binlog转储？我需要杀死这个.如果我杀了这个过程怎么办？
