Finding Minutes In Datetime Intervals [SQL Server2005]
May 29, 2008
[SQL Server 2005]
In a report there are following in parameters: from date, to date, from time and to time.
I need to match these search criteria€™s against start time and stop time in assignments.
The trick: How to write SQL that meets all different cases that can arise.
The query need's to traverse through every assignment,
and see if its start and stop time is in the interval given by the user.
It should then return the minutes from the assignment that is within the interval.
I'm thinking of packaging the minute "extracting" logic in a Scalar-valued function.
It should then take the in parameters from the user, and start time and stop time from the assignment as arguments.
To consider: Crossing midnight.
E.g. the user puts in
From date: 2008-05-24
From time: 22:00:00
To date: 2008-05-26
To time: 02:00:00
Since the user wants to evaluate a time span that crosses midnight,
I'll have to look in to time spans like:
2008-05-24 22:00:00 - 2008-05-24 23:59:59
2008-05-25 00:00:00 - 2008-05-25 02:00:00
2008-05-25 22:00:00 - 2008-05-25 23:59:59
2008-05-26 00:00:00 - 2008-05-26 02:00:00
Furthermore the start- and stop time can be partially in the above interval.
E.g. an assignment starts 2008-05-24 21:46:11 and stops 2008-05-24 22:36:05.
This would then yield from the time spans above 36 minutes.
The combinations seem never-ending€¦

I have the following generic table structure.
CREATE TABLE tableName (
...
, datetime_created datetime DEFAULT GetDate()
, created_by_user char(12)
)
I want to find out which records were created within a given period of time per user. For example I want to know if the user "georgev" (or any users) has created more than one record in this table within a 2 minute period.
Hopefully thsi will warm your brains this cold Monday morning :p
Any more information needed, let me know!

Hey :)I'm facing a lot of troubles trying to create a new pause/break-system. Right now i'm building up the query that counts how many records that is inside 2 fields. Let me first show you my table:
ID (int) | stamp_start (Type: DateTime) | stamp_end (Type: DateTime) | Username (varchar)0 | 17-03-07 12:00:00 | 17-03-07 12:30:00 | Hovgaard
The client will enter a start time and a end time and this query should then count how many records that are inside this periode of time.
Example: The client enter starttime: 12:05 and endtime: 12:35.The query shall then return 1 record found. The same thing if the user enters 12:20 and 12:50.My current query looks like this:SELECT COUNT(ID) AS Expr1 FROM table WHERE (start_stamp <= @pausetime_start) AND (end_stamp >= @pausetime_end)But this will only count if I enter the exact same times as the one inside the table.Any ideas how I can figure this out?Thanks for your time so far :)/Jonas Hovgaard - Denmark

hey all, i need to find the ratio of difference in 2 datetime variables and the difference of another 2 datetime vars. I figured the best way to do it is to convert the difference in both numerator and denominator to number of minutes.

I have a column in a table that stores the number of hours a task took to do. The column TaskDuration is a datetime datatype. I need to convert the hours to something that can be summed. Does anyone how this can be done? I tried CONVERT(nvarchar(5), tblTasks.TaskDuration, 108) but of course the nvarchar(5) cannot be summed. Maybe there is a way to convert the time portion to minutes and divide it by 60, anyway if someone can offer some help I appreciate it.

If I subtract 14 days from a datetime field, will the time of day that I run this query affect the resultset? I am running the query during "normal business hours", 8 am - 5 pm, and the records are entered during this time frame as well.

RESULT:
5/22/2008 10:00

Dear all,
I need to ignore the hours minutes and seconds elements of a datetime field - I've got a way of doing this in my select statement but it seems to be this can't be the most efficient way!
CONVERT(datetime, CONVERT(nchar(10), db.tab.field, 101)) AS date_key
Is there a better way?

I have a datetime field that is just the date and zero for the time element. I also have a varchar field that is of the format 09:25:30
is there an easy way to add these together?
I don't mind if they get converted to integer as it will be used for comparison.

I have two fields ID and Log data and log data is a 96 character long string of numbers representing 15 minute intervals from midnight to midnight.
I need to convert these 96 characters to a full 1440 characters which would mean taking each of the 96 characters one by one and making 1 character into 15.
I had Vb macro to do the conversion but now it's broken and I can't fix it. Getting it done in SQL would solve a lot of problems.
I then go from the 1440 fields and do log analysis like total time doing a specific activity but my query is dependent on having all 1440 characters.

Hi,My table has int Field1 and DateTime dtModificationTime. I maintain ahistory of changes to the table by inserting a new record with a newdtModificationTime. I need to be able to find the last insertedrecord. It's easy to do Select * from table where field1=x ORDER BYdtModificationTime. That works, but it hits all the records thatmatch the field. I need to come back with an exact hit. Can someonepoint me in the right direction?Thanks.

Hi All,
I am working on a line chart. The variable on the X- axis is DateTime. The requirement is to have the values displayed with an interval of 4 hours (or mabe 5 or 6 hours - basically every regular intervals). I am using a list control to Subreports to show around 10 reports.
HOW can I do this? The Major and MInor intervals only help in separating which samples will be displayed. But we cannot configure for regular intervals.
Please help.
Thanks in advance,
Manoj Deshpande.

I have collected perfmon data that is in every 15 seconds. I need to run a query that will only retrun rows that are 5 minutes from the last row starting at a specific date/time.
Here is the current query

"CounterDateTime" is in every 15 seconds. So starting from '2012-03-02 11:59:00' I need only rows for every 5 minutes after that.

I have a client that collects data from a manufacturing facility a one minute intervals. I already have sql statments to convert the 1 minute data to other timeframes (e.g. 30 min, 60 min, daily). However, now the client wants to look at data converted to irregular time intervals. For example, instead of looking at the first, second, third, etc. 60 minutes of a day, they wish to see data grouped irregularly: first 30 minutes, next 1 hr & 45 min, next 2 hours, next 1 hr & 30 min, etc. These irregular intervals could change; they may later want to look at the first hr, next 2 1/2 hrs, next 1/2 hour, etc.; or whatever strikes their fancy.
So far, all I've come up with is run one query for each desired time session and then do a join on all the resulting tables. Anybody have a better idea on how to do this?

Columns: EMpID - Date - WorkedHours
For each day I get details of number of hours worked by each employee in this table.
Now my HR wants a report with such columns

So, week will have Sum of hours worked by employee in that week
Month will have Sum of hours worked by employee in that Month
Qtr will have Sum of hours worked by employee in that Qtr

I have a situation where I have table with over a billion records and needs to be scrubbed. Table does have a field with date time timestamp. I have been deleting rows from the table using the script below which basically provides me delete statements by date for records older than 90 days.
But now on each day row count is over 30 million rows and it takes forever to delete by date and transaction log becomes humongous.
So I would like to scrub it in 5 minute intervals instead of daily for records older than 90 days. Even in 5 minute intervals the record count tends to be around a million. This will keep the delete slice small enough to not a gigantic transaction log.
declare @startdate Datetime
declare @enddate Datetime
set @startdate = getdate()-480
set @enddate = getdate()-90
--set @vStart = select convert(varchar,@startdate, 102)
print @startdate
print @enddate
WHILE (@startdate < @enddate)
BEGIN
print 'delete from vending where DetectedDate < ''' + CONVERT(varchar(10), @startdate, 101) +''''
set @startdate = @startdate+1
END
I am hoping to modify the script above to produce a script with statements like this for a window between last 90 and 120 days:
delete from vending where DetectedDate <'6/15/2015 8:25:00 PM'
go
delete from vending where DetectedDate <'6/15/2015 8:30:00 PM'
go
delete from vending where DetectedDate <'6/15/2015 8:35:00 PM'
go

Basically, length represents the # of minutes a person is scheduled for. We have 30 minute intervals. Interval_Num = (Length/30). I need the data to show each interval. For the above example it should only be 14 intervals.For the above example the solution should look like....

I'm trying to create a query to return Open, Close, Max and Min Price for each 1 minute interval. Source data has two fields - Price, and Datestamp at 5 second intervals.
I can calculate the Max and Min (below) and set the datestamp to the middle of the interval, but get stuck on how to also return the Open and Close price for each interval.
SELECT MAX(price) AS MaxPrice, MIN(price) AS MinPrice,
DATEADD(ss, 30, DATEADD(n,DATEDIFF n, '1/1/2006', DateStamp),'1/1/2006')) AS DateStamp
FROM MasterData
GROUP BY DATEDIFF(n, '1/1/2006',DateStamp)
Any ideas?

S.No. Marks
1 ------ 5
2 ------ 5
3 ------ 6 1st Average Value here (16/3)
4 ------ 5
5 ------ 6
6 ------ 7 2nd Average Value here (18/3)
7 ------ 7
8 ------ 7
9 ------ 8 3rd Average Value here (22/3)
10 ----- 8
11 ----- 9
12 ----- 8 4th Average Value here (26/3)
So basically I need a new table which will have 4 average values for the table above. Of-course the table can be much bigger and the average values can be at any nth value of S.No.
