Newer versions of SQL support the process list in information_schema:
SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST
You can ORDER BY in any way you like.
The INFORMATION_SCHEMA.PROCESSLIST table was added in MySQL 5.1.7. You can find out which version you're using with:
SELECT VERSION()
回答2:
The command
show full processlist
can be replaced by:
SELECT * FROM information_schema.processlist
but if you go with the latter version you can add WHERE clause to it:
SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';

Another useful tool for this from the command line interface, is the pager command.
eg
pager grep -v Sleep | more; show full processlist;
Then you can page through the results.
You can also look for certain users, IPs or queries with grep or sed in this way.
The pager command is persistent per session.
回答4:
You can just capture the output and pass it through a filter, something like:
mysql show processlist
| grep -v '^\+\-\-'
| grep -v '^| Id'
| sort -n -k12
The two greps strip out the header and trailer lines (others may be needed if there are other lines not containing useful information) and the sort is done based on the numeric field number 12 (I think that's right).
This one works for your immediate output:
mysql show processlist
| grep -v '^\+\-\-'
| grep -v '^| Id'
| grep -v '^[0-9][0-9]* rows in set '
| grep -v '^ '
| sort -n -k12

If you use old version of MySQL you can always use \P combined with some nice piece of awk code. Interesting example here
http://www.dbasquare.com/2012/03/28/how-to-work-with-a-long-process-list-in-mysql/
Isn't it exactly what you need?
回答6:
...We don't have a newer version of MySQL yet, so I was able to do this (works only on UNIX):
host=maindb
echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked
The above will query for all locked sessions, and return the information and SQL that is involved.
...So- assuming you wanted to query for sessions that were sleeping:
host=maindb
echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep
Or, assuming you needed to provide additional connection parameters for MySQL:
host=maindb
user=me
password=mycoolpassword
echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked
With a couple of tweaks, I'm sure a shell script could be easily created to query the processlist the way you want it.
