Going From 15 Minute Intervals To 1 Min Intervals?
Jun 3, 2015
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.

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
Select
DisplayString,
MachineName,
ObjectName,
CounterName,
InstanceName,
[Code] ......
"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 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

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?
thanks in advance.

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.

Emp 1 started work at 13:00:00 and worked 183 minutes
Emp 2 started work at 17:15:00 and worked 150 minutes

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?

I have data that looks like the following.
ID Date Time Length Interval_Num
1 10/11/2014 9:00 420 14
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....
ID Date Time Length
1 10/11/2014 9:00 30
1 10/11/2014 9:30 30
1 10/11/2014 10:00 30
1 10/11/2014 10:30 30
for 14 intervals up until 16:00

[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€¦

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.

I would like something I can do inline eg:
select convert(blahdatatype,a.datefield) as smallerdatefield
from
a
where a.datefield is a datetime. If a contains rows like:
datefield
---------------------
01/20/2005 22:17:23
08/23/2001 03:04:15
...
Then the SQL above returns:
smallerdatefield
---------------------
01/20/2005 00:00:00
08/23/2001 00:00:00
...
Is there any non-obnoxious way (eg: without have to result to using datepart a million times) to do this? For instance, Oracle provides a function called Trunc which does it, but I cannot find an SQL Server equivalent. Anyone? TIA!!!

Hello all,
I have the following very simple SQL Query:
SELECT TOP (100) AutoNumber, Date, ZNT, SAT, RAT, RH
FROM HV_Values
ORDER BY Date ASC
This shows the top 100 entries for a table (where there is a date entry every 5 minutes). Here's five sample records:
1 12/4/2006 4:12:11 PM 67.13 70.50 71.56 8.23
2 12/4/2006 4:17:11 PM 67.13 70.50 71.56 8.33
3 12/4/2006 4:22:11 PM 67.19 70.69 71.69 8.19
4 12/4/2006 4:27:11 PM 67.19 70.63 71.69 8.18
5 12/4/2006 4:32:11 PM 67.19 70.69 71.75 8.05
What I'd like to do with the sample query above is take an AVG for one hour for the values ZNT, SAT, RAT, RH...like I stated the records are every five minutes in the table, I'd like to create 60 minute AVGs.
Any ideas or sample queries I can work with?
Thank you very much! gad1

Just wondering if anyone knew if it was possible to create a SQL Server agent job that ran once every 30 seconds. I can't enter a value below 1 minute when editing the job schedule in Enterprise Manager.
Alternatively, I can create duplicate stored procedures and set one to run on the minute and one on the half minute. Thought there might be a better alternative to this though and I'll always have to be remembering to makes changes to both sprocs.
Thanks!

I'm trying to get the difference between the two times in minutes with the seconds rounded up or down
As an example the difference in the times:
1900-01-01 09:27:49.000, 1900-01-01 09:32:28.000 is 279 seconds which is 4.65 minutes,
using
select
cast(round(datediff(second, convert(datetime, '1900-01-01 09:27:49.000'), convert(datetime, '1900-01-01 09:32:28.000')) / 60, 2) as numeric(18,2))
I am receiving the value 4.00 instead of 5 which I would like 4.65 to round to. How can I get the difference in seconds to round to the minute ?

Just wondering what is the best time to ensure that we only return data when the datetime field is the same when compared between two datetimes within a minute difference.
As in the following should return the data:
'2015-04-09 09:00:20' compared to '2015-04-09 09:00:50'
And the following should not return the data:
'2015-04-09 09:01:20' compared to '2015-04-09 09:00:50'
The problem, is that I'm merging data from three different result sets, which they all have data for every minute, however, the timestamp can be different by seconds or milliseconds.
So, I'm only interested to return the data when the two fields that I'm comparing are equal within a minute. I need to ignore seconds and milliseconds.
