How to view Query Execution time
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 -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
Re: How to view Query Execution time
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.

Re: How to view Query Execution time
you can also use EXPLAIN, which will give you much more details. http://dev.mysql.com/doc/refman/5.5/en/execution-plan-information.html http://www.techiequest.com/mysql-visual-explain-hierarchical-view-of-query-execution-plan/ On Sun, Jul 31, 2011 at 11:45 PM, Suresh Kuna sureshkumar...@gmail.comwrote: Usually, at the end of the query running it displays the time how much it took.

Query execution time - MySQL
Hi, When performing a SQL query like SELECT Name FROM Customers. How do I obtain the time in which the query took to execute like 1.5 seconds etc Thanks, Neil _ All new Live Search at Live.com http://clk.atdmt.com/UKM/go/msnnkmgl001006ukm/direct/01/
Re: Query execution time - MySQL
Greetings Niel, Not much detail there (but I'll go off what you provided...). Some people limit the actual MySQL system for times it TAKES MySQL to execute queries. For THIS to be accomplished, MySQL has built-in functionality to measure the time is takes queries to take place so it can ... limit them. So, in essence, I guess we can extract that data and get it back to you for whatever usage statistic you are looking to measure. ( See: http://www.bigresource.com/MYSQL-what-is-execution-time-of-a-query-based-on-was-a-mysql-question--0PxW0B3P.html) or for usage in JDBC by calling the setQueryTimeout() function of a Statement object...and so forth. HOWEVER - Just so you know, if you execute the query MANUALLY via the *command-line of MySQL* it will tell you how long the query took. Just use normal SQL syntax, execute the query on the table and VOILA! Your answer: mysql query or mysql run the query (use the below quoted/threaded example as a starting place to write your own query...?) Take a look at this thread (it basically explains the answer with a bit more detail on what the output will be): http://forums.mysql.com/read.php?108,51989,142404#msg-142404 SELECT * FROM user_log; 15113 rows fetched in 5.3274s (0.1498s) SELECT BENCHMARK(1, RAND()); 1 row fetched in 0.0505s (13.2676s) I believe the results are the following: The first number is the time it took MySQL server to send the result set to the client. The second number (in parens) is the time it took MySQL server to execute the query itself. TOTAL TIME will EQUAL A + B (for total time it took on your server/P.C. or wherever you are running the query...). Many things come into factoring why it takes longer or shorter. So this is why I asked if you are attempting to optimize or what not, but that is whole new story. (( What Operating System are you running? This would be helpful to give you the step-by-step, so to speak. Or perhaps provide us with a bit more information ***Also, if you are looking to perhaps make it so queries take shorter times (optimization effort) to execute a little bit more about your MySQL database setup and machine(s) would be beneficial to us as well. )) Let me know if you have any questions.

RE: Query execution time - MySQL
Hi Craig, Thanks for your detailed reply. Basically what I'm trying to extract is the time taken from when I execute the mysql query in my C++ Builder program until the time the query has finished. So my question is can I build in to my SQL query SELECT Name FROM Customers the time the query actually took or do I need to do this outside of my query.

Hi Neil, If your using Linux then you have to install the glib RPM's in the usual way. I don't know about other platforms, but I am sure there will be a version of glib out there... Also ensure the correct include and link directives are in your Makefile, which you can get (on Linux) using the commands: # glib-config --cflags # glib-config --libs Ben Neil Tompkins wrote: Thanks Ben, but I don't appear to have the header file glib.h in my libraries.

RegardsNeil Date: Wed, 14 May 2008 07:21:04 -0400From: [EMAIL PROTECTED]: [EMAIL PROTECTED]: Re: Query execution time - MySQLCC: [EMAIL PROTECTED] Niel,Not much
detail there (but I'll go off what you provided...). Some people limit the actual MySQL system for times it TAKES MySQL to execute queries. For THIS to be accomplished, MySQL has built-in functionality to measure the time is takes queries to take place so it can ... limit them. So, in essence, I guess we can extract that data and get it back to you for whatever usage statistic you are looking to measure. ( See: http://www.bigresource.com/MYSQL-what-is-execution-time-of-a-query-based-on-was-a-mysql-question--0PxW0B3P.html ) or for usage in JDBC by calling the setQueryTimeout() function of a Statement object...and so forth.HOWEVER - Just so you know, if you execute the query MANUALLY via the command-line of MySQL it will tell you how long the query took. Just use normal SQL syntax, execute the query on the table and VOILA! Your answer:mysql queryormysqlrun the query (use the below quoted/threaded example as a starting place to
write your own query...?)Take a look at this thread (it basically explains the answer with a bit more detail on what the output will
be):http://forums.mysql.com/read.php?108,51989,142404#msg-142404SELECT * FROM user_log; 15113 rows fetched in 5.3274s (0.1498s) SELECT
BENCHMARK(1, RAND()); 1 row fetched in 0.0505s (13.2676s) I believe the results are the following: The first number is the time it took MySQL server
to send the result set to the client. The second number (in parens) is the time it took MySQL server to execute the query itself.TOTAL
TIME will EQUAL A + B (for total time it took on your server/P.C. or wherever you are running the query...). Many things come into factoring why it takes
longer or shorter. So this is why I asked if you are attempting to optimize or what not, but that is whole new story. (( What Operating System are
you running? This would be helpful to give you the step-b
y-step, so to speak. Or perhaps provide us with a bit more information***Also, if you are looking to perhaps make it so queries take shorter times (optimization effort) to execute
a little bit more about your MySQL database setup and machine(s) would be beneficial to us as well. ))Let me know if you have any questions.Standing by and I hope this
helped you.Sincerely,Craig Huffstetlerxq on FreeNode #mysql | #apacheOn Wed, May 14, 2008 at 6:13 AM, Neil Tompkins [EMAIL PROTECTED] wrote:

Query Execution Time Perl/DBD
Hi. How do I get the query execution time from Perl/DBD? MySQL client returns this in the console window. Is this value available through the Perl DBD interface? Thanks.

The obvious way to do this would be to get the time before and after the execution and then make a simple diff (after - before) I guess that is how the mysql client does it (butI'm not sure) I do not think that mysql itself provides this information.. how to get the time in Perl/DBD I do not know. but in java it would be long tb = System.currentTimeMillis(); // do the sql-statement long diff = System.currentTimeMillis() - tb; - Original Message - From: Gordan Bobic [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, November 21, 2001 12:49 PM Subject: Query Execution Time Perl/DBD Hi.

Query Execution Time
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 ?

Re: How to get Query Execution Time
Hi, at the mysql prompt i can get the exact time taken to run each query. how can i display this time in an HTML page via PHP. is there a function which gives me this time Unfortunately, no, there isn't a built-in function to do this. So, you'll have to resort to some DIY. But, it's quite easy... Something like this should do the trick: ?php // Record start time. $start = doubleval(microtime()); // Do your MySQL query here... // Record the end time and print duration. $end = doubleval(microtime()); echo "Query took " . strval($end - $start) . " seconds!"; ? I'm not exactly sure whether doubleval() will convert microtime()'s "123456 450" return string value into a number like 123456.450, but I seem to remember it does. If not, you'll have to settle for a resolution of only whole seconds, by using time() instead.
