How To Find Out How Many Times A Query Has Been Executed
How can you count the number of times your query has been executed? So I'm trying to set it up, so that I get a variable on every time someone views a review.
I have two querys right now, but honestly don't really know what I'm doing. And I'm assuming I have to increment viewcount everytime that query gets executed.
This query looks up the review:

View Last Query Executed
I was wondering if it was possible to obtain the last query executed on a particular table? I have a request to log the queries executed on a particular table for audit purposes, but not sure if this is possible? If I was hard coding the query before hand, I could obviously use this. However I am using php PDO connections following: Quote: $update = $db->prepare("UPDATE `table` SET {$fields} WHERE `id` = :id "); $update->bindParam(':id', $data, PDO::PARAM_INT); $update->execute(); The above is a simplified version, which is dynamically building the query. Essentially however I cannot obtain the whole query this way, so wondered if MySQL stored it ?

Measuring Query Times
I have read a few posts here and see that some people have questions regarding the length of time it can take to perfrom their queries. I would be quite happy reaching that stage because at least I would know how long mine take. :| How can the time delay be forced to output? Using MySQL 5.0.

Report Of Query Execution Times
Does mysql have a tool to record and report a list of all queries executed and how long it took to execute each query? If not can anyone suggest a tool I can use to do this? I've heard of mysql query profiler but does it capture queries from all sessions?

Query Single Table, Multiple Times
Before i narrate my issue, i would like you to preview my table structure : Table name = machine_info +------------+----------+------------+ | machine | tag_name | tag_type | +------------+----------+------------+ | machine101 | sge | farm | | machine101 | US | site | | machine101 | CRITICAL | status | | machine102 | CANADA | site | | machine102 | UP | status | | machine102 | sge | farm | | machine103 | CHINA | site | | machine103 | DOWN | status | | machine103 | sge | farm | | machine104 | US | site | | machine104 | CRITICAL | status | +------------+----------+------------+ Requirement : I would like have machines from all 'sites' (almost 15 in the actual db) with 1)status='DOWN' 2)status='CRITICAL' 3)status='UP' Example: (Here the results would be like) SITE|DOWN|CRITICAL|UP US |0 | 2 | 0 CANADA|0|0|1 CHINA|1|0|0 I use php to extract information, here's what i do : <?php $db = mysql_connect("hostname", "user", "password") or die(mysql_error()); $selected = mysql_select_db("dbname") or die(mysql_error()); $site_codes = mysql_query("select distinct(tag_name) from machine_info where tag_type='site';"); echo "SITE|DOWN|CRITICAL|UP ";

A Query To Find Something From Last 30 Days
So basically I am trying to do a query to pull up a "request" that is over thirty days old. How do I setup the other half of the inequality to automatically adjust for what 30 days old is each day.

Does MySQL Keep A Log Of Executed Queries, Etc.
I've made several posts in recent months to learn how to do things manually (instead of using phpmyadmin or Navicat). I realize that this is a long shot--particularly since I don't see a log table in any MySQL databases on my server--but is there a log of queries or sql commands that have been executed on my server? Specifically, I'm wondering if there is a way I can trace some of the complex fixed-width imports that I've accomplished with Navicat so that I can replicate them on my own.

Find All Games A User Has A Top 3 Score In (was "Need Help With A Query")
I am trying to create a query that will go through a scores table for me and find all the games that a user has a top 3 score in. Here are the table that are relevant I think... CREATE TABLE files ( fileid int(11) NOT NULL auto_increment, file text NOT NULL, icon text NOT NULL, filelocation int(1) NOT NULL default Ƈ', iconlocation int(1) NOT NULL default Ƈ', customcode text NOT NULL, title text NOT NULL, description text NOT NULL, keywords text NOT NULL, width int(11) NOT NULL default Ɔ', height int(11) NOT NULL default Ɔ', category int(11) NOT NULL default Ɔ', timesplayed int(11) NOT NULL default Ɔ', status int(1) NOT NULL default Ɔ', filetype int(2) NOT NULL default Ɔ', dateadded date NOT NULL default ��-00-00', rating int(11) NOT NULL default Ɔ', totalvotes int(11) NOT NULL default Ɔ', totalvotepoints int(11) NOT NULL default Ɔ', scores enum(Ɔ',Ƈ') NOT NULL default Ɔ', PRIMARY KEY (fileid) ) TYPE=MyISAM AUTO_INCREMENT=2285 ; CREATE TABLE scores ( scoreid int(11) NOT NULL auto_increment, fileid int(11) NOT NULL default Ɔ', score int(11) NOT NULL default Ɔ', username text NOT NULL, userid int(11) NOT NULL default Ɔ', usercomment text NOT NULL, dateadded date NOT NULL default ��-00-00', PRIMARY KEY (scoreid) ) TYPE=MyISAM AUTO_INCREMENT=16 ; CREATE TABLE users ( userid int(11) NOT NULL auto_increment, username text NOT NULL, password text NOT NULL, email text NOT NULL, status enum(Ƈ',Ɔ') NOT NULL default Ɔ', usergroup int(11) NOT NULL default Ƈ', joined date NOT NULL default ��-00-00', played int(11) NOT NULL default Ɔ', comments int(11) NOT NULL default Ɔ', avatar text NOT NULL, avatar_uploaded enum(Ƈ',Ɔ') NOT NULL default Ɔ', location text NOT NULL, website text NOT NULL, gender int(1) NOT NULL default Ɔ', favourite int(11) NOT NULL default Ɔ', receiveemails enum(Ƈ',Ɔ') NOT NULL default Ƈ', newpm enum(Ƈ',Ɔ') NOT NULL default Ɔ', confirmation text NOT NULL, PRIMARY KEY (userid) ) TYPE=MyISAM AUTO_INCREMENT=8 ; ( Basically the query would need to search through the scores table to find if the specified user $userid has the top 3 (by top 3 i mean 1st, 2nd, or 3rd highest score) scores of any game in the scores table. The end resukt would be a list that contained the fileid of the game the user has a top 3 score in, the actual score, and the position (1, 2, or 3) Im not sure if I am even explaining this right cause im kind of tired. I am a novice MYSQL user but this just has me stumped

Number Of Times
I have a query that grabs 500 rows from 1 field within 1 table. In this table. Each user will have 500 rows associated to them from within that table. So if there are 2 users then there will be 1000 rows. Each time 1 user executes the query, it grabs their 500 rows. If 2 users execute the query simultaneously, then this means that there are 1000 rows, all of which will be selected; 500 by one user and 500 by the other. If 3 users access the table simultaneously, then there are 1500 rows and so on. My question is how many users can execute this query simultaneously before we see performance loss?

Records Between Two Times

I have this query: Quote: Select hours_id from hours where curtime() between 'open_time' AND 'close_time'; It partially works, but its not working if the close_time is after midnight (i.e 1am = 01:00:00 in database). I can't figure out the issue with the difference between AM and PM.

One To Many Multiple Times
I have a 'links directory' database that currently contains 4 tables: category, subcategory, region and links. My links table contains company names and, among others, three fields catID, subcatID and regID. Each of these are related to primary keys in the other three tables, category (catID), subcategory (subcatID) and region (regID). My issue is that the records in the links table can be in multiple regions, multiple subcategories and multiple categories, but the way I have it designed, each record in links can only be associated with a single catID, subcatID and regID. Currently the only workaround I can think of it to have duplicate entries in the links table for a single company, but with every variation of catID, subcatID and regID. This will result in a very large table, but I cannot currently think of any better idea.

Dates And Times.
You can't have two timestamp columns in a database both with the default now(). - why I would want to is not the issue. You can't use the data and time functions, such as CURRDATE()/CURRTIME() provided by MySQL as defaults for date/time type columns. Is there a way to use something like 'select currtime();' as the default for a column? so my question is, how do I use ANYTHING other than one timestamp with the default value of now() for date/time defaults in MySQL.

Dates And Times
I have a field in a DB called "customerJobDate" which is configured to store full dates (ODBC dates) e.g. "2006-03-06 08:30:00". Now this does work i can update insert and delete the records perfectly, But if i query the DB asking for all dates that match 2006-03-06 regardless of the time (Date only) then the result returns 0 rows unless any of the dates in the column have 00:00:00 as the time. This works: 2006-03-06 00:00:00 This does not work 2006-03-06 08:30:00 I hope someone can help me as I am finishing this app and this is the only thing holding me back.

Struggling With Dates And Times!
I'm using MySQL 3.23 - I know it's old but it comes as default on Linux distribs and I just want something consistent between home, my ISP and work. I want to work out the time difference between two entries on my database (I'm using PostNuke and have two posts which are stored as integers, ie unix times). I can see that there is now a datediff() and timediff() function but they don't work hence why I mentioned the version I'm using. Can anyone tell me how to get the difference between two dates - I am assuming I subtract one from the other but don't know how to convert the result into something useful (like days and hours etc) because I'm not sure what the unix time is made up of. I guess an easier version of that lot is : is a unix time just a second count?

Is there a way I can import large amount of data into MYSQL without timing out? Also the access database that I convert over gets updated every week. I don't know which records get updated or added. Also the app I am using only works with Access so I can not completely convert over. Is there a way I can update the MYSQL without having to import that huge file again. Maybe something that will not override the records that are same just change the modifed ones and add the new records.
