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.

Date Queries
I have an events calendar that I am working on and need to be able to query the database for a specified month, for example: march 2005 How would my query string look: $query = "SELECT event FROM calendar_events WHERE event_date >= 2005-3-01 AND event_date <= 2005-3-31"; The reason why I ask, is because I saw this, when looking at an example:
Date Queries
SELECT * FROM tbl_hire WHERE hire_out >= "2006-06-01" AND hire_in <= "2006-06-30" I have created a calendar with coldfusion which scrolls through the months. So I can click backwards into the past and forwards into the future. I am using 'tbl_hire' to store items that have gone out on hire and also store the date when the item is due back. So when I scroll through the calendar I need to be able to see all the items that have been sent out and therefore not available to rent out. I have 2 questions or queries, 1) how do I tell the sql what month I am on - so If I've scrolled back to May 2001 what do I need to have in the SQL? 2) at the moment with the SQL above if I have an item booked from "2006-06-05" to "2006-07-05" it won't display it as not being available to rent - is "<=" incorrect command to use?

I've created a table where one of the fields is the date a particular person joined a company. How do i compare this date to the current date, to get say, someone who has worked for the company over x amount of years? Without having to put the current date in manually
Date Queries
I am not convenient in writing queries. My doubt is, i have some list of datas stored in a table. I need to display only those datas that are stored 5 days before. Every time if i use this query it should display only those datas that are stored in the las 5 days.
Queries And Date Fields
My tables have a date field (in the DATE format), and I would like to select rows that are more recent than a certain date. I tried a select query using (for example): select * from table where date > 2005-05-16; But this returns all the rows, including dates prior to 2005-05-16. Is there any way to select using a date field?
Trace Sql's
Sql Server has a program that we can configure to trace the sql's executing. Is there any program that does the same thing for mysql
Track And Trace
I work for a 5 man company selling track and trace service over the internet. I'm the only full time software guy. We are growing, and I can see soon we are going to start hitting BIG problems, we aren't make any money yet. This doesn't help as I think we need a real MYSQL + Internet guru guy. So my option was this hoping to get some simple answers I can use to before It get out of hand. We have one server running our software and we just bought another. So can it be setup that both servers have there own database, and update each others database. This means if something happens to one server this other can take over the other. I was thinking to make it customer based with server to logon to.

How To Trace Mysql Server
Is there any tool for mysql server to trace and identify the slow query(ie the query which takes more time to run) like sql profiler in sql server. I want to identify the query in VB and optimize that. If there is any way to identify the slow query.
Ability To Trace SQL Events In MySQL?
I am coming from the MS SQL world and always found the ability to trace what SQL events were hitting my database to be powerful. Does this exist in MySQL and if so where is it or is it an add-on?
Complex Queries Versus Multiple Simple Queries
I am constructing a database to contain information about stories posted on my site. Information included will be things like title, author(s), genre(s), story codes, synopsis, etc. I worked out that storing this information properly, so that it can all be searched on, could take as many as ten tables. My question is this: Is a single complex query really better (more efficient for the server) than multiple simple queries? In other words, I may need the information for as many as 25 or even 50 stories for a single page. Is it better to get all of the information out of a single, massive, complex query, or is it acceptable to get the information essentially one story at a time, which could mean 25 or 50 simple queries...?
Appear 2 Times

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))
Many Smaller Queries Vs. Large Comlicated Queries
I am wondering if any one can help me. I have a page that will run around 85 smaller queries but if i combine the queries it will go down by almost half. This page is a high traffic page and I don't a complicated query taking up mysql resources while it created a temp table and such. My question is this: Is it better for mysql to run a lot of smaller queries (ex: simple selects with zero or one join, group by) or one larger complicated query with everything combined. The thing i have to keep in mind is that the mysql selects are comming off the localhost that the web server is also running on so they share the same resources.
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.
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?

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.

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?

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

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:
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?
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

Calculating Time Difference In Minutes Between 2 Times
I have two columns in a table start_time and end_time (stored as datetime). I wish to work out the time difference in minutes between these two values. If the difference is 1hr 30 minutes I wish to get 90 (mins) I have tried: SELECT TIME_FORMAT(TIMEDIFF(start_time, end_time), '%i') FROM table ... This returns justs the minutes (e.g. 30) and SELECT TIME_FORMAT(start_time - end_time, '%i') FROM table .... no such luck.
Linking Table Entries Multiple Times
I have no idea how to handle certain kinds of relations between tables: I have a table called 'labels' and a table called 'artists'. Every artist belongs to at least one label, but could also belong to any higher number of them. How would I solve this in my database architecture? I discarded the idea of simply adding 10 columns called 'label1', 'label2', etc; Also I have found the ENUM and SET datatypes, but the possible values entered there should be set at table creation time which is also not quite what I'm looking for.
Which Is Faster In MySQL? Comparing Unix Times, Or DATETIMES?
I'm leaning towards using unix times inserted into my MySQL for ease of use in manipulating the data with PHP. I think this will be the final decision, which one would be faster? -- Mysql: * INT (4 bytes) * DATETIME (8 bytes) * TIMESTAMP (4 bytes) -- My PHP application does alot of querying from the database to compare specific data within TIMERANGES, so always, I'm querying with "time >" or "time <". My question is would doing the WHERE time query with the native MySQL DATETIME be faster, than doing a WHERE query with the unix timestamp?
