Usually, at the end of the query running it displays the time how much it
took.
Or else enable the profiling and run the query to check the exact time it
took for execution at all levels.

Dear all,
I want to know how much time did it take to run a sample query.
In postgresql, we enable timing by \timing command.
Is there is any way to enable in Mysql
Thanks

If you are using MySQL to serve an application, then it is advisable to do
the logging through the application scripts. For in most cases, you might
require more information other tha
execution time, however.
Mukul, can you elaborate on why the slow query log doesn't suffice?

I'm not sure if we can call it a bug. But spending 8 seconds (and

Hello.
There is no builtin possibility for this, but you may write your

and invoke 'mysqladmin kill' for long threads.

Is there a way to setup a maximum query execution time per user. I

looking for a way to kill a query per user if it takes longer than XX

Hi
Within mysql, all queries return the time taken to execute, ie
20 rows in set (0.77 sec)
35 rows in set (1.33 sec)
etc.
Is it possible within perl, or C for that matter, to get the time taken for the MySql
server to get the data ?
