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.
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?
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?

How To Write Query To Select The Max(version) For Each Unique File_name Record?
I am a MySQL newbie trying to write a query that selects file_name records possessing the highest numbered version for that unique file_name. I show sample data and two trial queries below. Logically I want to use max(version) as a constraint in a Where Clause. However, the max() function is not allowed directly in a where clause. I have contemplated a second table to track the max version for each file name. I would like to structure the data in an efficient manner for query performance when the data set grows to many thousands of unique file_name records with many hundreds of versions each........
Search And Write, Or Write And Recover?
The problem: I need to generate a 'unique string' for each row in a table. I already use auto_increment for system dependencies between tables. What is the best approach one of these or another? After generating a candidate 'unique string' the two strategies that came to mind are: 1. to then search the table's column to see if it is already assigned; locking the table for write while searching and writing the new row, or 2. set the column to UNIQUE when defining the table. Just go ahead and write the new row if you get a "non-unique" exception, generate another 'unique string' and try again. I've tried both on a small XP laptop and get "lock timeout exceptions" rather quickly using #1. But replace those with lots of re-writes when there starts to get "collisions" of 'unique string's.
Select Dates
I need to select all dates between (and including) two given dates. something like SELECT DATE() BETWEEN '(dynamic date)' AND DATE_ADD('(dynamic date)', INTERVAL 90 DAY) so that the result set would contain 90 days.... Many thanks in advance for your help.
Select Dates After A Specified Interval
The code i have come up with thus far is as follows: SET @StartDate='2005-11-22', @StopDate1='2007-11-22', @date1= '2006-01-31'; #Note: do not set StopTime greater than 23:59:59 SELECT Table1.StopDate As Date FROM dbase1.Table1 where StopDate= @date1 @date1 = DATE_ADD('2006-01-31', Interval 2 DAY) WHERE ((dbase1.Table1.StopDate)>= @StartDate) AND ((dbase1.Table1.StopDate)<= @StopDate1) GROUP BY Table1.StopDate; date1 is the first date in the series. Can someone point out where i am going wrong or if there is an easier way to do this?
Select Range Of Dates
How can I select a continuous range of dates? For example If i want all of the dates between Jan 01 2007 and Apr 02 2007 to be listed as: jan-01-2007 Jan-02-2007 jan-03-2007 .. Apr-01-2007 Apr-02-2007 What Select statement could I use? The date format is not important.
Select Fields Between 2 Dates
I am trying to develop a booking system in PHP with MySQL but I am having trouble writing some code that checks to see if a new booking clashes with another. e.g. in the database I have a booking that runs from 2008-03-10 to 2008-03-20. When I add a booking I want to check to see if a booking already exists between these dates. Is this possible? I am not an expert with MySQL but the closest I got is to carry out 2 query's: SELECT propertyid, arrival_date, departure_date FROM bookings WHERE arrival_date BETWEEN '$arrival_date' AND '$departure_date' SELECT propertyid, arrival_date, departure_date FROM bookings WHERE departure_date BETWEEN '$arrival_date' AND '$departure_date' but this obviously will not check if a booking is made in between these dates, e.g. if I try and add a booking from 2008-03-13 to 2008-03-18 it will not think that there is a collision of booking.
Retrieving Dates In SELECT
Im trying to select some results from a query and use a WHERE clause to extract ones that were only created greater than July 1st 2007. In the table, there is a 'created' column which stores a unix timestamp. The sql im using is "SELECT post,created FROM table1 WHERE created >= 1183348800" It seems that the WHERE clause is just comparing the acutal number and not realizing that it is a unix date.Is there a function that I am able to use?

Converting MS Access Dates To MySQL Dates During LOAD DATA INPUT ?
My insert code is below. The MySQL server is on my local machine and is version 4.1.22. I am exporting from an access table with 6 fields to a mysql table with those 6 plus 5 more fields. The main problem I am having SO FAR, is converting dates. The data file dates are formated like: 2/2/2006 0:00:00, 12/20/2006 9:22:05 Any ideas how to format those into mysql friendly dates?

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.
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))
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.

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.
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.

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.

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.
Help Me Write This Join?
Hi there, been ages since I wrote any sql, and I'm a little stuck but I figure this is easy for you folks. I have this original query: $posts = $wpdb->get_results("SELECT ID, post_title FROM " . $wpdb->posts . " WHERE post_status='publish' ORDER BY post_date DESC"); And this gives a lists of all posts. However, I want to only grab posts by a certain category now, say category #9. This information is kept in an intersection table called wp_post2cat. The columns in that table are: rel_id post_id category_id category_id is what I want, and post_id is the key pointing back to the original post. Posts can have multiple categories, but I just want the one listing where it's category 9, which is audio. So pseudocode would be something like: SELECT all posts WHERE post_status equals "publish" and the category is equal to audio (9).
