Last Query Execution Time
Is there a way to retreive the elapsed time for the prevously executed query? Alternatively, Is there a way to query the current time in fractions of a second?

Query Log With Execution Time?
I have developed a big property portal web site and have probably written about 1000 different SQL queries in the process (OK, maybe only 500 or so) but a lot. The site is now gaining popularity and although it is on a dedicated server I want to make sure that everything is running smoothly. I have optimised several tables with indexes etc. and have sped up certain tasks, but would like to know if there are any other queries that take too long and should be optimised. Is there a way to log all queries together with the time it took to execute the query? Is this already logged and if so - where is it?

Query Execution Time In PHP Script
I am interested in displaying the query execution time as mysql does from the console, but using php. I've looked everywhere for this and can't find anything. Does anyone know how to display this information to the browser via php? The information must be there since the console provides it. I checked the php function mysql_info(), but that only shows records, duplicates, deleted, matches, changed, warnings, etc. Didnt see any specific php function for getting execution time.

Execution Time
After we execute a statement in mysql, it reports the query execution time in the format: n rows in set (t sec). We may do something like this to get the execution time: $time_start = getmicrotime(); mysql_query( "" ); $time_end = getmicrotime(); $time = $time_end - $time_start; But it includes extra CPU time to run two getmicrotime() functions and one subtraction. Is there any way to obtain the execution time directly from mysql without running extra functions or calculations?

Improve The Execution Time
i am new to db2 want to ask questions about the performance of my sql commands for a view based another 3 views the sql commnads are as following: create view b_central_subgroup as select communicator as central_member, project_id as project_id from b_normalized_communicator intersect select initiator as central_member, project_id as project_id from b_normalized_initiator intersect select monospeaker as central_member, project_id as project_id from b_normalized_monospeaker it takes 4.4 seconds to execute this sql. it likes that the time is the summ of the other three views. Can the execution time be reduced through some other methods? If it is possible , then how ?

Measure Execution Time
I would like to measure the execution time of my queries in order to evalutate the performance in/decrease for different changes. Even if I use 'sql_no_cache' the query executes MUCH faster the second time I run it, and is therefore not representative of the true performance. How to I avoid this problem? I'm using MySQL 4.1 on a windows server 2000. I be glad to get an explanation to why the query executes faster the 2nd time.

Database Size And Max Execution Time
I have now got a large database that is getting to a size of about 4Mb when downloaded (dumped / uncompressed).On my Web server everything seems fine. But when using said database on my home server (localhost) I am recieving Max Execution time of 30 second errors constantly.How can I stop this from happening and is it likely to start happening on my web server soon?

Measure Execution Time Of Mysql Script
I am trying to measure the total execution time of a mysql script that I run using the mysql command line client in batch mode (-e "source myscript"). The --tee option does not work for the batch mode so that I could then gather and add up the execution times of the SQL queries as logged by the server. Adding a tee command in the script itself is not working. Using the time command (in Linux , and timex is not available) on the mysql program is also not helpful as I think it does not include the execution time of the queries on the mysql server side, but only the system and user times corresponding to the client process.

Sum Total Of A Time Field
We have a table with a field of type TEXT storing the time for certain actions (ie. 0:30 - for 0 mins 30 secs, 1:20:00 - for 1 hr 20 mins 0secs). We've come to a point where we'd like to sum the entire field up and get back the total time. I wish we established this filed as a time data type rather than TEXT but that's the way its set up. How would you go about achieving this? Perhaps I need to convert the TEXT to some other format to get back a more usable value for my PHP code to use?

Tracking The Total Time Each Day A User Spends On Site
My DB is currently setup like this: SQL Code: id   userid   timecheck      visit_type 1    255   1205896013     IN 2    255   1205896017     refresh 3    255   1205896025     refresh 2    255   1205896150     IN I basically need to grab the difference between the time from the first IN of the day to the row marked refresh just before the next in, and then repeat wherever the value in the timecheck column = the same day. PHP Code: $sql= "select * from timetable where timecheck = '".date("M d, Y", $row['timecheck'])' and visit_type between 'IN' and 'refresh'";

Maximum Execution Time Of 300 Seconds Exceeded (was "MYSQL Error")
I have a huge database 400mb+ in size which i have exported into a .sql file. I tried to run this export script into a new database and it runs fine until three quarters into the scripts execution and the following error appears: ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<br / > <b>Fatal error</b>: Maximum execution time of 300 seconds exceeded in <b' at li ne 1 I believe this error may relate to "delayed_insert_timeout = 300". How do I increase this limit in mysql - maybe it may solve the problem but then again it may not . Any advice is most gratefully appreciated - As you can imagine if the script runs fine for 3/4 of it and then an error appears, stating the error is on line 1, it will take me days to go through the whole script (hundreds of thousands of rows) to find the error as I assume the error does not reside on line 1 as this line would have been executed. I am running the script on mysql 5, and via source /path/****.sql on linux.

Query Execution Too Slow!
I have migrated from MySQL 4.1.22 to MySQL 5.0.45. Many of the queries that were working on my old server is working too slow in my new server(MySQL version 5.0.45). I am not aware why is this happening. Actually there is no error message or query failing. The query is executing, but the time taking to execute the query is too long. This problem is not occurring for all queirs, but only for some complex queires, that is queries with Left Join or Right Join, Group By etc. I have also checked the MySQL details through SSH(that is by mysql> SHOW VARIABLES;) Now one thing I found is there is lot of difference in key_buffer_size, table_cache, join_buffer_size, read_buffer_size, read_rnd_buffer_size , table_cache etc between my new server MySQL and old server MySQL. Will this be the reason for query execution taking too much time. Can any one guide me why this is happening. The striking thing is that these quires was working very much fine and faster in my old server.

Slow Query Execution
Right now I am fazing one issue which is getting hell out of me. I am explaining the issues step by step. 1.I have one site running from last 3 years with large database and there is one main table which has maximum load. 2.Now, I have redesigned the site with lots of changes within this table too. 3.The problem is that the server is same, queries are same but output in the new database is taking 50 times more execution time. 4.I also just copy paste the table, and fire the same query... Strange even that is not working... Is it something where newly added table or database is having issues in the server? I have tried all, compared the structures of the data and table but still the query result is too slow on live testing sever. While same query in main site of same server is running perfectly.

Check Query For Syntax Prior To Execution
I was wondering if it was at all possible to check an SQL query prior to execution for syntax errors? A method which wouldn't alter the data to which the SQL statement related to. I'm guessing you could perform a transaction of sorts, but is there another way?

Slow Execution For A Left Outer Join Query
Whats likely to be the cause of slow execution for a left outer join query? The original query joins three tables but even if I narrow it down to one it still takes a long time to execute. $query = "select distinct materials.* from materials"; $query .= " left outer join materials_products on materials.material_id = materials_products.material_id"; There's 914 rows in the materials table and 1348 row in the materials_products table Is it likely to take a long time for this amount of data or is there likely to be a problem in the table(s) set up or query?

Query Pages Printed By Percentage Of Total?
I'm very new to MySQL and have a query I'm trying to achieve, if anyone can point me in the right direction, I would greatly appreciate it. I have a table created to store print job logs from a print server: Table = printLogs logNum mediumint(8) logDateTime datetime docNum tinyint(3) docName varchar(200) owner varchar(25) printerName varchar(25) printerPort varchar(50) sizeInBytes varchar(50) pagesPrinted smallint(10) What I'm trying to do is find a query that, based on a 'printerName', will display 'owner' and percentage derived from the total number of pages printed to that 'printerName' for a given date range. Something like this: +--------+--------------------------+ | owner | Percentage of total jobs | +--------+--------------------------+ | Mary | 50% | | John | 30% | | Kim | 10% | | Sue | 10% | +--------+--------------------------+ Each row of the table is a different print job and can be one of about 20 different owners who have printed any number of pages to any of 10 printers. The main reason for the query is to be to determine which group/owner uses each printer the most.

How To Get The Total Number Of Rows With A Query "limit" ?
I would like to paginate the results of a query on several pages. So I use a query with a limit X offset Y to display X results on a page. But for the first page, I need to run the same query with a count(*) to know how many pages I will get (number total of rows/ X). The problem is my query is very slow (maybe 5s) because there is much worch to do, and on the first page, I need to run this query twice (not exactly, but ...) so the page is very very slow to load. My question is : is there a function to get the total number of rows even on a query with "limit" ? Or what could I do else ?

Trying To Get Total Count Plus Count From WHERE Clause In One Query
I am fairly familiar with mysql, have been using it with php for about a year now for my development work. One query I am stuck on is the following. I am doing reporting, and need to find the count from a WHERE clause compared to the total count for that group. For the sake of an example, let's say I have a prize table that contains a complete list of prizes. There is a column to list if the prize has been won or not (prizeUsed - Y or N) and another that has the prize name (prizeName - string). I want the final result to list something like: Total Prizes ____________________ 100 of 850 ......

Time Query - Please Help?
I’m completely baffled by a query that I thought I had working yesterday, but I can’t get it working today. Here’s the screnario: I’m publishing a story to the web and I don’t won’t it to be published live until: -The current date (type: date) is less or equal to now -The current time (type: time) is less or equal to now So here’s my query: select * from cms_stories WHERE section = 'news' AND published_web_date <= NOW() OR published_web_date IS NULL AND (published_web_time <= NOW() OR published_web_time IS NULL) ORDER BY story_id DESC LIMIT 1 Now the query works for the published_web_date, but not for the published_web_time. It seems to ignore that as you can see from the screenshot returned below from that query.

Limiting Query Time
Is it possible to limit the query time in MySQL (3.x or 4.0)? For example, I'd like to have any query that takes more than a specified number of seconds just quit automatically. Seems dumb, but on a web site, nobody is going to wait minutes for a query to return so they refresh anyway. So on a busy server, MySQL ends up with several queries running that all take a long time to finish which compound to make it even slower. A simple time limit would solve the problem. Yes, I know that the queries should take less time, but again, on a busy server, sometimes the longer queries do take a long time (10 minutes or more) to complete.

Execute Time Of A Query
I'm running a SELECT * query on a table with over 3,000 rows. I need to know the execute time on the query. PHPMyAdmin shows it to me, but because they automatically add a LIMIT 0, 30 I suspect the time is only for those 30 records. It also has a feature to prevent web server timeouts that prevents me from setting the LIMIT to 0, 3100. BTW, I'm programming in PHP. Does the time to run the query get automatically passed when PHP sends the query to MySQL? <? PHP $Query = "select * from my_table where 1"; $Result = MYSQL_QUERY($Query); ?>

Time Zone For Query Browser?
My server time is set to CST. phpMYSQLadmin shows CST. The website that the information is stored on is CST. When I do a query from MySQL Browser, it's providing information back in GMT. Does the browser undo timezone? It makes since on a corporate level, so that the time is always being pulled up correctly. So, my question is. If all my servers and sites are all set to CST, do I still need to do queries with a time zone change in it, CST?
