I have several EVENTS executing every two seconds, I would like to kill those which are
running longer than 1 second.
Are there way to control query execution time on MySQL 5.5?
cheers Arman.
You can use the SHOW PROCESSLIST command to see running processes in MySQL.
Here's a link: http://dev.mysql.com/doc/refman/5.0/en/show-processlist.html.

I had 2 queries in the editor window. I cancelled it 2X as I had the wrong info in my query. I stopped the background process and thought I was terminating the query. I went into the Session Monitor and see those 2 queries in the Query status under the Activity column. My question is, are these 2 queries still running as they are NOT in sleep mode? If they are how can I terminate them?
Thanks for any help/direction.
Open up a MySQL console, do a
show full processlist;
to find the ID of your queries. and then kill that particular ID with something like this
kill 32843;
I have an expensive reporting query that can take 1-20+ seconds to run. (Depending on how much data it has)
Is there a way to kill a mysql process/query from running after a certain amount of time?
I see this:
mysql auto kill query
Is this the best route? I have also read that I should try to improve my queries. I will look into this too, but I am just asking for suggestions on the best route.
First run
show processlist;
then find the query that you want to kill then run
kill "1";
1 is the id of the query you want to kill you have to choose it according to the list
What's the easiest way to find out how long it takes to evaluate a long-running MySQL query (longer than 10 minutes)?
The issue is that:
When I try to run it from MySQL Workbench, I get a timeout error.
When I look at the process list, sometimes the process finishes executing when I'm not looking and I don't know how long the script has taken.
I used a loop in my php script to run insert queries into my db. The loop was looping thousand times. I stop my php script while it was till running. Nevertheless, my db table keeps on getting populated continously. I guess that there must be a queue. but this is only a guess. So I am wondering if I can stop all the pending queries from being executed? Also I am wondering if it is possible to see that queue somewhere? Thank you in advance for your replies. Cheers. Marc.
There is no queue, unless you were using INSERT DELAYED.
You can kill the process that is inserting the data like this:
Run SHOW PROCESSLIST to find the id of the connecton you want to kill
Then run KILL CONNECTION <thread_id> to kill that connection.
SHOW PROCESSLIST will give you a list of all currently running queries
I have a very slow query that is built by the ORM and I'm curios how could I find out the exact query being executed.
I cannot monitor it from the mysql-slow.log because it never finishes the execution (as in I don't have eternity to wait for it, more than an hour in an still waiting).
Also I cannot get the query from the ORM, just after execution. And the only way I think of getting it is from the process list.
show processlist \G
But my problem is that most of the query is trimmed of, even before the from keyword.
This question has been asked before but with no answer https://stackoverflow.com/questions/3741356/find-queries-from-process-id-mysql-5-1-x
Any suggestions?
If your query is formatted in multiple lines, some MySQL clients will only display the first line. To see full output run SHOW FULL PROCESSLIST; query in MySQL console.
