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:

Where To Find A History Of Queries Executed By Mysql?
I have a problem with one application I have written and I think you can help me to find the solution. My problem is that once my application is running for some hours (sometimes 20 hours, sometimes 250 hours) the CPU used by mysql is 99%. In this case the PC and the application is for sure very slow.
I cannot reproduce this problem on my machine but I imagine that somewhere (for some reason) my application is bombing mysql with a lot of queries.
I now have to find which query is it to find where do I have this query in my code and try to unsderstand where is the problem.
My question is the following:
Is there any way to get an history of all queries executed by mysql where we can see the time of each query?

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?

MySQL Query Times Out From Page But Not Console...
The query works ok when executed from the console, but never executes from the any page. - When I use MySQL Administrator to view the threads this particular thread gets stuck on "copying to tmp table on disk"...

Executed Queries
I am doing database synchronization project . I wanna know, is there any file where the mysql stores the currently executed queries that is list of currently executed queries so that I could extract those queries from there and send them in mail for synchronization.
[note: I am using linux platform]
I added log-bin=[querylog_filename] in my.cnf and using mysqlbinlog command I was able to view the currently executed queries
stored in [querylog_filename].000001 binary file but I was not permitted to access .

Procedure Sucefully Executed
How can I know if a procedure executed sucefully?

Monitor SQL Statements Being Executed
How can I monitor what SQL statements are being executed on any table in realtime for any user? Example... I use Oracle Session Manager to do this with oracle. I want the same ability in MySQL 4.1.5

Open Last Executed Mysql Statement Via !vi
how to retrieve previous long sql statement that you ran via shebang and vi? what is the temporary files mysql writes to?

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. Date is in this format: 2006-07-18 11:59:59

$result = mysql_query('SELECT * FROM requests WHERE reqtime < "2006-07-18 11:59:59" ');

How To Find Max Value Of Query Using Group By
When I run the following query

select count( username) as count, username
from friends  
where status="validated"
group by username
order by count;

it gives me a list of each username in the and how many times it appears in the friends table

Can anyone tell me how to rewrite this query so that it tells me which username appeared the most times in the friends table.

Find And Replace Query
recently i completed a forum move to a new URL, however there are many posts on my board that still use the old URL for reference. Is there a query that i could run on my database to find all the instances of the first URL and replace it with the second?

Need A Query To Find All Spam Entries In My DB
I need to tweak the following query to help weed out spammers who have created accounts. I want to try and:

1. Show accounts that have alpha characters in the zip field
2. Show accounts that use more than 5 numbers in the zip field

select zip, country from users where country = 'United States'

Query To Find Friends Of A Friend
I'm experimenting with writing my own social network script but I'm struggling a bit with one of the queries. I have a users table, and a friendships table containing user_id and friend_id columns which are both foreign keys linking to users.id (sql dump at end of this post).

if x is a friend of y, and the friendship is approved, then y is also a friend of x. I'm using this query to retreive all the friends of x (in this example, x has an id of 99):

Can I Use Mysql Query In Jsp To Find Table?

Mysql Query Search And Find In String
I have following values in a field of mysql table. These values are stored as string [varchar] in the field.

Values : 3,4,10,21,20,8,100,2,6

How can I check through MYSQL query that 100 or 21 or 4 exists in the string?

Any clues:

Select * from loan where last weeks sunday<Loandate>last week's saturday.

Query By Dates To Find History Records
what is the correct way to query on a date field in a table to pull a value that is older than 3 days?

Date field format is 2007-04-04

I only want records where the date is 2007-04-01 or earlier.

Comma Delimited List Query Find
I am building an app. using ColdFusion along with Mysql. I need to create a select query that checks if certain Element ID's are contained in a comma delimited list which are stored in the MySQL database.  

Normally, this would be easy, just something along the lines of:

select * from table_name
where Comma_list like '%ID1%'

The problem comes in the creating of the ID's there's nothing to stop the user from creating an ID that contains the entirty of another id...example:

Find Hightest Number After Finding First Query
i have this code but it does not display the highest number or anything.

it should be searching the field 'name' for the string $name and only display the one that has the highest number in the 'number' field.

what am i doing wrong?

$res = mysql_query("SELECT MAX( number) FROM data WHERE name='".$name."'");
$high = mysql_result($res, 0, 'number') or die(mysql_error());
echo($high);

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...

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

Appear 2 Times
i'm having this problem finding out the right sql query.
i have two tables A & B
the userid in table A appears as FK in table B
i need to list userid that appear 2 times or less in table B which has a where clause column3='Yes'

how do i go about it>?

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.

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.

Upload Times
I need to upload 2 star catalogues to the mysql database. the first time i tried this i filled up the HD in 2 Days, my instructor mentioned that journalling was taking up most of the space and decided to remove-it.

now, with journalling turned off, i have started re-uploading the catalogues, but have noticed a significant decrease in "write" speed.

my question is, does journalling speed up writing data into mysql tables? i have roughly 180GB of data to upload, and it took me 4 days to upload 3GB's when last time it took me this time to upload 100GB.

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.

About Dates And Times
I have form with drop down boxes, where folks enter dates and times, I have used implode and explode to format the dates, now I want to write those dates to mysql, I know mysql has its own date and time functions, is there a way to convert my php formatted dates and times into something that mysql will recognize and store as a time and date or does php have a function that will convert it and then allow it to be stored in date/time format in the database?

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 a table for a restaurant database with two fields open_time and close_time in TIME format. I want to be able to select all records that fall between open_time (when the restaurant opens) and close_time (when the restaurant closes).

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.

Ordering Times
i have some vlaues in a database, they are 12 hour times, how would i go about sorting it so 12 comes before 1, as it is its going 1 2 3 4.... 12 etc etc, do i have to use a 24 hour time? then from there function it to show 12 hour when displayed

Comparing Times
I'm creating a voting system, and want to prevent people from cheating. Therefore I'm logging their IP, and the time they voted, and what I'm planning to do is have a script which will delete any records which have been in the database for say 24 hours.

To get the length of time I was gonne use:

HOUR(TIMEDIFF(NOW(),time))

Subtract Two Event Times
I am trying to formulate a complex query to get some good info straight from SQL, rather than post-processing in XL.

I have a table as follows:
EventID Integer (key)
ActionID Integer, 1 = event on, 2 = event off
dtStamp Date

I want to get the duration of each Event.

I.e. I need, for each Event:
dtStamp(actionID = 2) - dtStamp(actionID = 1)

I was going to try:

>create view EventOnTime as select EventID, dtStamp as EventOnDtStamp from EventLog where ActionID = 1;

>create view EventOffTime as select EventID, dtStamp as EventOffDtStamp from EventLog where ActionID = 2;

>select eventOnTime.EventID, eventOnTime.EventOnDtStamp - eventOffTime.EventOffDtStamp as EventDuration where eventOnTime.EventID = eventOffTime.EventID;

... but I can't create views with this version of SQL (server version: 4.0.20-standard-log)

Dump File Times Out?
I have a huge Access database (about 50,000) records. I use Access dumb to create a sql file which I can them go into phpmyadmin and import the records. Well, after a while the process times out. 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.

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?

Disabling An Entry More Then 3 Times A Day.
Like if you enter 3 times a day the same text. It echo's something instead of writing in the database. Do i need to add a date on where the line was added to it?

Call To Database Times Out
using ZenCart 1.3.7, and when it calls to the database after clicking on "go to checkout" it hangs and then returns the following error message:

I get this message after clicking on "go to checkout"
2013 Lost connection to MySQL server during query in:

I've checked with my host, and they are able to do a php call to the database just fine.

Adding 1 Year To All Times
suppose that

dbX -> tableX

id columnX
1 1190815874
2 1192975748
3 1196695027
4 1196796789

how can i add 1 year all value where year is 2007 ?

my sql do not run

UPDATE `tablex` SET `columnx` = DATE_ADD(`columnx`, INTERVAL 1 YEAR)
WHERE DATE_FORMAT(FROM_UNIXTIME(`columnx`),'%X')) = 2007;

Slow Loading Times
It takes more than 30 seconds to load the phpmyadmin page. On a localhost server.
It says
Fatal error: Maximum execution time of 30 seconds exceeded in c:appservwwwphpmyadminlibrariesmysql_wrappers.lib.php on line 101

This sometimes also happens when loading my local website that uses MySQL.
I've tried reinstalling, but it doesnt help.

Export Records Times Out
I try to export all records from my db about once a week. I use phpmyadmin and select all tables structure and data and export as file. Well the problem now is it always times out when I do this. The db only contains about 18 tables and maybe 20,000 lines of data. The tables average about 12 fields each. So now I'm exporting a few tables at a time. Is there something I can do to change this?

Left Join 2 Times
SELECT f.id as id, f.forum_name as forum, f.forum_desc as description,
count(forum_id) as threads, u.name as mod
FROM forum_forum AS f
LEFT JOIN forum_posts AS p
ON f.id = p.forum_id
AND p.topic_id=0
LEFT JOIN forum_users AS u
ON f.forum_moderator = u.id
GROUP BY f.id

Output: 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 'mod FROM forum_forum AS f LEFT JOIN forum_posts AS

Does this query contain any syntax errors? Can mysql perform left join 2 times?

Ordering Results By Number Of Times They Appear
I'm not really sure the best way to explain what I want to do, so I'm going to make a really simple example to illustrate what I mean.

Let's say I have a table with column "temperature". There are 5 entries that contain the word "hot", 3 entries that contain the word "medium", and 2 entries that contain the word "cold". However, these entries are not in any particular order.

Is there a "SELECT * FROM" statement which will return the results by order of popularity in the following manner?:

hot (5)
medium (3)
cold (2)

I have a script I'm working on and I'm trying to figure out the best way to do something like this.

Select Same Row Multiple Times Using Column
I've seen this asked before and although someone answered that it is possible, they did not post the solution, so if anyone can enlighten me that would be helpful.

Basiclly with table info


name | quantity
john | 3
anne | 1
will | 2
Return results

john
john
john
anne
will

Who Do I Write Select With Dates And Times
i have to cols, date and time. who can i do, SELECT between (date 1,time 1) to (date 2, time 2)?

for example i want to get the recordes between 2007-01-01 23:00:00 to 2007-01-03 03:00:00 ?

Trace SQL Queries Date/times
I have a web application connected to mySQL 4.1 database. I would like to know the date/time for the queries executed on mySQL DB when any operations performed from the UI.

Is there any mechanism to trace the information related to any query updates happening on the DB when operations are performed from the UI.

Datetime And Timestamp Recording Different Times
I have a datetime field that records date and time. This field records
when rec is created. I also have a timestamp field that records
whenever the record is updated. I noticed that when i first create the
record, the update time is about 3-5 minutes before the create time.
The update time and create time has to be identical. How can one lag
the other? Im executing sql from a php page.

Joining A Table Multiple Times
I was wondering if it was possible to join 2 tables on 3 different feilds, but I don't want the 3 feilds to limit my results... I'll try and explain:

Table 1 = "offices"
Table 2 = "employees"

The offices table has the addresses of all the offices and 3 extra feilds "manager", "supervisor", and "employee". (these 3 feilds have a numeric value equal to the primary key in the employees table)

The employees table has the employee information like address and phone number and such.

I would like to write a query that would pull the office name as one feild, followed by "manager", "supervisor" and "employee".

Currently I have this, but it only pulls the employee and I'm not sure how to get the manager and supervisor to be a part of the query:

SELECT CONCAT(office.id_store, ' - ', office.storename) as offices, CONCAT(user.lastname, ', ', user.firstname) as fullname
FROM office LEFT JOIN user ON office.empoyee = user.id_user

Mysql Result Times Over 15 Seconds
I am having problems with result times. I run a search from my website and it takes around 15 seconds to generate the mysql query and then 40 seconds to load the page.

Query To Find Friends Of Friends
I'm experimenting with writing my own social network script but I'm struggling a bit with one of the queries. I have the following table structure:
users
------
id - integer (pk)
username - string
friendships
----------
id - integer (pk)
user_id - integer (fk to users.id)
friend_id - integer (fk to users.id)
approved - boolean
if x is a friend of y, and the friendship is approved, then y is also a friend of x. I'm using this query to retreive all the friends of x (in this example, x has an id of 99):
SELECT
CASE
WHEN user_id=99 THEN friend_id
ELSE user_id
END
AS fid FROM friendships
WHERE (user_id=99 OR friend_id=99)
AND approved IS true;
so far so good, but what I'd like to do now is extend the search to find all friends of friends of x, but I'm not making any progress.
