Elapsed Time Between 2 DateTime Values
MySQL Version 4.0.20 on a Linux server.

How does one get the elapsed time between (2) DateTime values?
I need the answer to the nearest minute.

Is upgrading to Ver 5 with its more robust date/time functions the only
solution?

You can directly subtract 2 DateTime values and a long integer results.
What is that number?

Storing Dates And Time To Database
I was wondering how to store this date into the database:

Friday, August 28, 2015

and this time:

8:00PM

I have one field that collects the date and another for the time.. Im looking to store them in this format, 0000-00-00 00:00:00.. Is there some way to turn this date "Friday, August 28, 2015" into this "0000-00-00 00:00:00" so it will be inserted into the database using DATETIME??

Comparing Dates Y, M, D , Time In Sql Query
ok.. ive finally got my nice little calender setup to output my dates

now

how do i query my database

for example ive got 2 variables
$startdate = 2006-1-1 00:00:01
$enddate = 2006-1-1 23:59:59

these represent the 1st and last second of the first of january 2006

i have a cell in my table (table called challenges) ( cell called time) that contains a date in the same format for each entry

how do i get all the entries between the start time and the end time..

can i use less than < and more than > as these are not really integar values

the column type is datetime but there is also another column of type datetime

Find Time Difference Between Two Dates

More Questions About The Mysteries Of Time And Dates In Mysql
part of a query I am running goes as follows:
floor(sum(unix_timestamp(dtp.endtime)-unix_timestamp(dtp.starttime))/60) as total.....group by dtp.activityno

dtp.endtime and dtp.starttime are both datetime fields.

I am saving the result into a temporary table and what it gives me is the total number of minutes spent on the selected activitynos...

My question is: if a result from this query is for example 123 (and 123 minutes is the correct number of minutes-2 hrs and 3 minutes) how can I show this result as a date field in MySQL? that is as 02:03:00?
I tried setting the field type to date when creating the temporary table but that just made a mess of the actual number of minutes.
Anybody have any ideas?

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?

Also, how do I convert currency fields in the load data process? I know you use SET by what kind of formula?

Update String Dates Into Mysql Dates
I've got a table that someone created with varchar fields for month, day, and year. I've added a DATE field to the table, and now I want to combine all three of these strings into one DATE and stick it into the DATE field. Once I've got this done, I can delete those three varchar fields and just have the nice DATE field.

Here's the command I've tried in several variations but no luck--syntax errors every time:

UPDATE SET OCR_Entry_Date = date_format(str_to_date(concat_ws('-', OCR_MM, OCR_DD , OCR_YYYY) ,"%b-%d-%Y"), "%m-%d-%Y") WHERE OCR_YYYY = '1974'

OCR_Entry_Date is a DATE field and the others are the varchar fields. My logic is basically:

1. concatenate the separate field values into a single string
2. convert the string into a date
3. format the date in the way I'd like it in the table

MSSQL Dates -&gt; MySQL Dates Automatically?
We're using data feeds that were originally meant for MS SQL and the dates in the data feed (tab delimited text files) are formated like:

Oct 21 2007

In MySQL, the date fields are formatted as datetime fields and when we do an import the dates all come through as 0000-00-00 00:00:00.

We're importing using the MySQL "LOAD DATA LOCAL INFILE" command and just dumping the text files right into freshly truncated tables.

Is there a way when loading the files to find and replace the dates maybe? Can MySQL convert the dates?

I have a shell script downloading an archive and uncompressing, then it runs a PHP script that loops through the files runningt he LOAD DATA command.

Any advice would be appreciated... I'm just looking for the easiest (and least server-intensive) way to get the date issue fixed. We've already tried begging the vendor but they're not yet ready to start supporting other date formats (even though their MS SQL db can output a date format friendly to MySQL).

Thanks!

List All The Dates Between 2 Given Dates Using SELECT
how I can list all the dates between 2 dates (inclusive) using SELECT sql statement in mysql?

I have a member table with the following columns:
id int autoincrement
name varchar(40)
join_date date

I want the following output (date, count of members joined on that date):
1 April 2009...... (2 members joined)
2 April 2009...... (0 members joined)
3 April 2009...... (3 members joined)
.....so on ...upto
30 April 2009.....(1 members joined)

For the above output I need the SQL command that is valid in mysql. Is there anyone who can produce the above result with a single SELECT command. Please don't suggest that is possible using php for loop or creating a mysqlorary table first and then inserting all the dates into it. Then make a join between mysql table and members table using date as GROUP by column etc. etc.

I know this is possible using some user variables as I searched through the various SQL tutorial sites. But I am unable to figure out how I can produce a list of all dates between 2 given dates.

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

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)

Dates Between Dates
Is it possible to query dates between two dates straight from mysql database? Example: I have two dates in my database that function as start of an event and end of an event.

I can get results when I seek an event that starts 2006-07-30 and ends at 2006-08-06 with following sql-query:

select eventid from database where (startdate between '2006-07-30' and '2006-08-06') or (enddate between '2006-07-30' and '2006-08-06');

Or by using any date values that go "over" the specified dates in database. Problem is that I would like to get the event also when it's active between these dates. Like from 2006-07-31 to 2006-08-02, but no result will be returned with this example query:

select eventid from database where (startdate between '2006-07-31' and '2006-08-02') or (enddate between '2006-07-31' and '2006-08-02');

Dates In SQL??
I'm having some trouble with dates in MySQL.

I'm developing a site that has an area for news. I've created a table that's called NEWS and it has 3 columns: id, date, news_text.
For the date I've given these properties: datatype:timestamp, default:current_timestamp.

The problem arises when I retrieve the news. I want the date to be printed as well in the form of YYYY-MM-DD, but I guess due to the current_timestamp, I get YYYY-MM-DD HH:MM:SS.

1) Is there a way to ommit the time??
2) How can I change the format and make it DD-MM-YYYY??
