TIME Interval MAX
I have a table that looks like this: Date, Time, Price 2001-01-03, 00:01:00, 1.5989, 2001-01-03, 00:02:00, 1.5988, 2001-01-03, 00:04:00, 1.5984, 2001-01-04, 00:01:00, 1.5999, 2001-01-04, 00:05:00, 1.5954, 2001-01-05, 00:01:00, 1.5985, 2001-01-05, 00:06:00, 1.5952, I need the MAX price for each day. I came up with a stored procedure that does it but it takes 14 hours. I would like to know what is the best way to get the MAX price for each day. Is there a way to avoid a stored procedure? I thought about rearranging the table, like diving the table into smaller tables one table per day or maybe using an INDEX on the date column to speed up the procedure.

Group By Time/Interval/Minutes
I would like to ask, that how could I group by minutes, without using the FLOOR. My problem is that I am receiving data in real time. for example the current time is 2008.01.01. 15:35:14 I would like to receive the following Time, user 2008.01.01 15:35:14 | user1 2008.01.01 15:34:14 | user2 2008.01.01 15:33:14 | user1 2008.01.01 15:32:14 | user3 2008.01.01 15:31:14 | user5 2008.01.01 15:30:14 | user7 Floor isn't good for me because it would give a table like this 2008.01.01 15:35:00 | user3 2008.01.01 15:34:00 | user4 2008.01.01 15:33:00 | user2 2008.01.01 15:32:00 | user5 2008.01.01 15:31:00 | user6 2008.01.01 15:30:00 | user3

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?

I need to show items which are dated ($startdate or $enddate) >= $testdate, and within this or next month. Example: the selected items need to go from 2005-12-15 until 2006-01-31. This is what I have. Unfortunately, LAST_DAY is not functioning with my host's server. SELECT * WHERE cat='1' AND ( $startdate >= $testdate AND $startdate <= DATE_FORMAT($testdate,'%Y-%m-01') + INTERVAL 1 MONTH - INTERVAL 1 DAY ) OR ( $enddate >= $testdate AND $enddate <= DATE_FORMAT($testdate,'%Y-%m-01') + INTERVAL 1 MONTH - INTERVAL 1 DAY )

DATE_ADD And INTERVAL Respectively
imaging the following example: SELECT `mytable`.`start_date` + INTERVAL `mytable`.`cycle_value` DAY AS `date_in_future`; This will evaluate the cycle correctly and assign it to `date_in_future`. Now I want to be able to let the user choose the interval type so I added a column `cycle_value_type` with the type ENUM('DAY', 'WEEK', 'MONTH', 'YEAR'). Now I tried to make this query: SELECT `mytable`.`start_date` + INTERVAL `mytable`.`cycle_value` `mytable`.`cycle_value_type` AS `date_in_future`; There will be an error stating a query syntax error. I assume this is an issue of datatypes. What kind of datatype should my column `mytable`.`cycle_value_type` be of in order to get this "date unit" into my query? Or is there a function that extracts the value from `mytable`.`cycle_value_type` directly into the query so that the parser won't even see the `mytable`.`cycle_value` column in the query?

Easy SELECT With OR Takes A Very Long Time
We've got a database with about 1000000 books. A query in the table BOOKS for the TITLE 'java' is very fast. We have a fulltext index on the column TITLE. However, if we want to do a exact same query and include the rule that the book with ISBN '0131016210' always should be included - then the query take several seconds to finish: SELECT * FROM C_BOOK WHERE MATCH(NAME) AGAINST ('java') AND (ISBN LIKE '0%' OR ISBN LIKE '1%') OR ISBN = '0131016210' ISBN is the PRIMARY KEY. Is there anything I can do about this?

Query Date Interval Question
I have used MySQL for quite some time but have just recently started making more advanced queries. I hope someone can help me with this. The problem is this: I have a table of Orders with Price, Date, Salesman and ID. To get the total sales of one user for say week 2 or February is not very hard, that would be something like: SELECT SUM(Price) AS SumPrice FROM Order WHERE OrderDate BETWEEN "2007-02-01" AND "2007-02-28" AND Salesman="Bob" GROUP BY Salesman The problem now is that I would like to have a result with like weeks 1-10 or Jan-May, with each week or month and its correspongding SUM on a separate row. Can anyone help me and say what is missing please? I reckon that my query above would be a subquery in a larger query specifying the intervals, but I can't figure out how to do it.

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)

SELECT INNER JOIN Performance VS Single Table SELECT
I have designed my database using a somewhat oriented approach. Rows are objects, and different type of objects are in different tables, but since my objects share a common set of fields like ExpireDate, Archived, Draft, CreateDate, CreatorID, etc; I have an 'objects' table with these columns, and I have set up a foreign key in other tables where there is a need for a row-to-row integrity. Now my question is, since I have to SELECT using INNER JOIN with object and the corresponding table, merely to filter out archived rows, I am wondering if I would be better off actually putting the common fields into each respective table and get rid of the 'objects' table altogether. I mean, is it more job for the server to actually JOIN the tables for each SELECT versus having a clean design with object oriented approach ? How bad is my design, and what are the recommendations of experts who obviously were tempted to create an object oriented database design?
