Dumping Data From A Certain Time Period
Every time I make changes to my MySQL database on my local PC, I have to dump the whole table on the server. This can get a bit annoying when the table contains thousands of records.Is there a way for MySQL to log all the updates you've made since a certain time and then use this file to dump it on the server?

Removing Data After A Certain Period Of Time
What I want to do is run a query that inserts data into my database, but removes itself on a set date. Is there any way to do this? Basically, I have something like this: INSERT INTO table (blah, blah2) VALUES (blah blah, 1) I would like to do something like: INSERT INTO table (blah, blah2) VALUES (blah blah, 1) {{{ INSERT CODE TO MAKE VALUES GO AWAY WHEN CURRENT TIME = SET TIME TO GO AWAY }}} There is an alternative to this if I have to. This is all for a PHP script, and instead of having MySQL automatically remove the data, I could add a time to remove to the table, insert the value for it in the INSERT query, and run a query on the index page consisting of something like <?php $timeToRemove = SELECT_TIME_TO_REMOVE_FROM_DB; if($currentTime => $timeToRemove) { REMOVE; } ?> so that every time someone hit the index page, it checks if it is time to remove the values from the DB and if it is, it does so. But of course, that adds an extra query/queries, and I'd like to avoid that. Edit: It may be useful to note that this is for a message board system, and I am dealing with making usergroup changes temporary. So instead of removing the values, perhaps it would be more useful if I could simply have MySQL reverse itself after a certain time has passed. But that seems unrealistic for some reason now that I think about it, so the alternative may be my best choice. Any suggestions from you all would be nice as well, if you've any ideas.

Generating DAILY Min&Max Over A Period Of Time, Based On A "DateTime" Field
how to print the minimum and maximum of a specific field, between two datetimes (both having the time 02:00:00) - so I did this: WHERE ((tblvalues.dtLPDateTime)>="2006-01-01 02:00:00" And (tblvalues.dtLPDateTime)<"2006-01-03 02:00:00")) Now I want to print those min and max values but for each day in this cycle, i mean, for this example, there would be two records like: Day Min Max 2006-01-01 02:00:00 -> 2006-01-02 02:00:00 | 40 | 59 2006-01-02 02:00:00 -> 2006-01-03 02:00:00 | 49 | 68 where at this point i`m getting min=40 and max=68

Dumping Data To Easily Import Into MS Access
I have a db that I need to dump into a format that can be easily read my MS Access. I tried the dump with regular PHPAdmin. Then I used the dump to run a query in MS Access. Errors occurred because MySQL inserts a backslash, "", in front of an apostophe that user enters in a text field and MS Access doesn't know how to interpret that. Any ideas for easily getting whatever kind of data from MySQL to MS Access?

Add A Period 5 Places From The Right?
I'm trying to modify some latitude/longitude columns which have the values like: 3482787, -11782842 They're stored in text fields currently. I basically just need to put the decimal in the proper place, which should always be 5 places from the right, so i need to make the above value (and the other 6.3 million rows) look like this: 34.82787, -117.82842 I cant seem to find the function syntax to do this in MySQL, tho I'm sure it exists. I dont want to write a PHP script to do this because it seems like PHP chokes on me if I work on more than 500 thousand rows at a time.

Grouping By A Date Period
Let's say I have a table with dates that range from January to May in each record. Is it possible to group the records by a date range, for example: I want to group the records by a date period of 1 month, starting at the 3rd day of each month. So what I'd want to see is, five records for each month (jan 3 to feb 3, feb 3 to march 3, march 3 to april 3, april 3 to may 3).At the moment I have the following: select id, _date, sum(cost) from test where _date >= ' 2005-01-03' and _date <= date_add('2005-01-03', interval 1 month) group by extension union select extension, _date, sum(cost) from test where _date >= date_add(' 2005-01-03', interval 1 month) and _date <= date_add('2005-01-03', interval 2 month) group by extension The trouble with this is that each month interval has its own select query and that the increase in the month is hard coded (interval 1 month for example). Is it possible to use SQL to inrement the month?

Time Data Type
I have a column of data that represents a racing participants race finish time where time is measured with fifths of a second. I currently have the column stored as a varchar(4) data type because i could not figure out how to store it as a time and keep all my data. Here's an example of some of my 4 character stored data, followed by the explanation of what it really means. 2014 which means 2 minutes 1 second and four fifths of a second 1590 which means 1 minute 59 seconds and no fifths of a second 1561 which means 1 minute 56 seconds and 1 fifth of a second 2003 which means 2 minutes no seconds and 3 fifths of a second Is there any way i could get this into a time data type that won't lose the fifth of a seconds? I want to be able to output it in a human readable format like 2:01.4 1:59.0 1:56.1 2:00.3

Reduce Data Loading Time
At present i am working with a database that contains all countries and their cities. My database is in mysql. The city table contains 3079703 cities. When a user selects a country i need to populate the city dropdown for that country. I use Ajax technology to retrieve city from database based on the selected country. But I am facing a problem with the speed as it takes a long time to retrieve city data and return generated dropdown control from server using php. I have already tried to use filebased caching (transferring all the city data into separate files for each state and country) and then tried to load from these files but didn't gain any significant speed improvement. I also then tried using indexing in city table on country code and state code but it still takes time to load. Could someone please give me any techniques or optimisation tips so that i can load the cities within a short time.

Real-time Automatic Conditional Data Manipulation
So it happens that I have to delve into the fields I feel very uncomfortable in ... for now. I'm working off the existing MySQL DB, in which I have to: 1. Analyse in real time (or nearly there) every newly entered row in the "entry" table (data is inputed by a third party) based on the set of criteria and depending on the outcome create new entries either in "bad" or "good" tables 2. Perform the same operation but on the different set of criteria on the new entry in the "good" table and create new record in the "output" table, which is then visible to the third party (but contains very different data from originally entered) My original plan was to dive into writing triggers, but this feature does not seem to be supported in the platform of my choice. Are there any GUI tools (or anything that would not require PhD in quantum physics) that can help me to create conditional real-time updates between tables within one MySQL database triggered by appearing new record?

Converting Time Date Values To An Absolute Number For Data Retrieval
We have a medical DB which stores several medical variables from real cases. We use this data to build display trending information on a visualization display for doctors. Pulling and rendering graphically ALL the data takes time and processor that may not be available in a real world situation. What we want to do is to pull data at specific intervals of time based on the time length a doc wants to view. For example: if we have 2500 records all of which have a time stamp and each record is for an interval of 15 seconds how can I query the DB such that I can pull every data point at an interval of 75 seconds apart from the beginning time and display it? I was thinking if I could convert the timestamps to an absolute numeric value (assuming MySQL starts it's times at some point in the past) then I could figure out the query from there.

PHP/MySQL Sorting By Date & Time (using Non Military Time)
This is probably a simple issue but I have searched online and can't find an answer. I am using PHP/MySQL and I guess the most intuitive would be to have three select boxes containing HOUR / MINUTE / AM,PM option. Then store the time into mysql using there functions so I can output the data sorting them all by date and time. All the examples I have seen are for military time only but I'm sure there has got to be a simple mysql function or php function that converts non military to military and a formatting function to display with the AM / PM. But I have not found it.

How To Retrieve Mean Time Between Time Stamps
I have a table that stores failure information of external application. The time stamp of every failure event is stored. Now I'd like to make some system performance & reliability statistics calculations based on time stamps in certain recordset; mean time between failure MTBF, down time DT, etc. Example: 2007-09-27 12:23:52 2007-09-27 08:50:23 2007-09-26 23:31:34 2007-09-26 21:45:33 Here the times between are (hours:mins): 3:33, 9:18, 1:46 and MTBF=4:52 Any effective possibility to make this example within a single query - or a procedure is needed?

Date-time Overlaps Another Time
had a time question in mysql... i have a start and end time for a meeting table and i am comparing whether a new meeting conflicts with another meeting in same room on the same date. i was wondering if i could check whether the 'date-time duration' in anyway overlaps another meetings date-time duration. visualized below... ............|____compareToThisMeeting__| .....|_________meetingNewOverlaps__________| i was doing something dumb before i realized i needed soemthing more complex (checking whether the start time of new meeting was 'BETWEEN' the start and end times of a meeting and whether the end time time is as well but i forgot the duration/middle value hehe). (using asp) and just returning booleans with a mySQL SELECT statement is what i am looking for like... //within a loop in asp for meetings on same date/room "SELECT '"+ year+"-"+month +"-"+day +" " + startHourString +":" + startMinuteString +":00''"+ " BETWEEN '"+ thisMeetingStart +"' AND '"+ thisMeetingEnd +"'"; (this doesnt cover the 'middle' overlap areas though)
