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)

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.

Date Field, Time Field, Sort By Date And Time
I have a MySQL date field (e.g 13/12/2006) and a MySQL time field (e.g.13:00) in the same row. I'd like to join these two fields to make a date/time field (e.g. 13:00 13/12/2006) on the fly and to be able to sort the query results on the resulting field.

About Date And Time
i have created a table using the following code: ------------------------------------------------------------------------------ create table tt(name varchar(10), enddatetime timestamp, startdatetime timestamp, difference timestamps); ------------------------------------------------------------------------------ after i have created, i insert the following into it: ------------------------------------------------------------------------------ insert into tt values('bob',null,'2006-10-1 12:12:12',null); ------------------------------------------------------------------------------ and i want to find the difference between the enddatetime and the startdatetime. so i tried the following: ----------------------------------------------------------------------------- select enddatetime,startdatetime, sec_to_time(unix_timestamp(enddatetime)-unix_timestamp(startdatetime)) as difference from tt; ------------------------------------------------------------------------------ but the value came out from the difference column was xxxxx:xx:xx *(where x is an integer). as you can see, the year,month,date and the hour are all mix up together(xxxxx). so i was wondering whether my code or my variable was wrong?? and by the way, how can i show the difference in terms of seconds?? like converting the enddatetime and the startdatetime into seconds and substract them together?

Date Time
what I want to do is very simple however it seems I'm having trouble figuring out how :D I got a date_time field in a table. I want to retreive all the records that match yesteday. Something like: select * from table where datetimefield = now() - interval 1 day HOWEVER because it's a date_time field (and I can't split it in 2 fields for other reasons), the above query won't return anything. Seems I could do a select * from table where datetimefield between yesterday at 00:00:01 and yesterday at 23:59:59 but I can't find the functions for that.

SQL Date Time
I've been having trouble trying to figure out the best way to select only the rows with timestamps within the last X amount of hours, days, weeks, months. So I guess my SQL statement in plain english would be: Give me all the rows that have a timestamp between NOW and X days/months ago and count how many times a row was submitted per hour/day/week/month within those rows. I'm pretty sure this is possible but I can't seem to wrap my brain around it.

ORDER BY Date And Time
I am using php to extract variables from a MYSQL database that get loaded into a calendar application. Most everything works great. The only problem occurs when more than one event occurs on the same day. The event date and time are stored as separate variables in the database, thereby making it difficult to ORDER BY date and time. The result is that all of my events appear on the proper day, but they do not appear in chronological order. Is there a way to order by date and time? I currently have the following: Code: $SQL_Query = "SELECT eventID, eventDate, startTime, endTime, title, description, linkName, hyperlink FROM events ORDER BY eventDate";

Date/Time Issue
I am very new to MySQL. I have used other databases before so I am trying to figure out how to do things I have done before. I want to create a table with a column of type DATE. When a row is inserted in the column I want the date the transaction took place to be inserted as the default in the column. I have tried a couple of things, but everytime I execute anything like: SELECT CURDAT (); MySQL reports Error 1146 Table mysql.proc doesn't exist. What have I not setup correctly? Same thing happens when I execute: SELECT VERSION (); I am using version max-5.0.18 on a Linux system.

Indexing Date / Time Fields.
If we have a date/time field and are doing frequent queries WHERE {date/time field} BETWEEN TimeA AND TimeB Does it make sense, query speed wise, to create an index on the date/time field? The reason I ask is that TimeA and TimeB are significant down to seconds. My *assumption* is that with a large amount of data scatter very few records will contain duplicate date/time points. And that under these circumstances, indexing will be of little value since every date/time point will need to be examined in detail. Date/time fields are actually floating point numbers after all. In other words, the assumption I am making is that if most of the data in a field is unique, then indexing will yield little or no query performance benefit. Is my "assumption" valid? Would an index on the date/time field speed up this type of query?

Date Time Columns And DATE_ADD()
DATE insert_date TIME insert_time DOUBLE offset The offset column stores the number of hours from UTC time. The insert_date and insert_time are inserted in UTC time. I need to select insert_date and insert_time but I want to automatically adjust for the offset on the SQL end. So I did something like: SELECT DATE_ADD(insert_date, INTERVAL offset HOUR) as `date`, DATE_ADD(insert_time, INTERVAL offset HOUR) AS `time` FROM myTable But this doesnt work though, as I need to factor in the offset into the entire insert_date and insert_time concatenated. How is this possible? I want to return the insert_date and insert_time individually.
