SQL 2012 :: Calculating Difference Between Two Times With A Twist (between 9am And 5pm)
Mar 25, 2014
I have Two Time fields in a table. Time(0). An "opening time" and a "closing time". They can hold any legit time.
I want to calculate in a SELECT Statement how many minutes within this range are within 9am to 5pm (which I'll convert to hours).
For example, here's an easy example:
OPEN: 9:00:00
CLOSE: 17:00:00
8 Hours/480 minutes
I could get this easy enough with a DATEDIFF function.
But what about:
OPEN: 08:00:00
CLOSE: 18:00:00
10 Hours total but only 8 of those 10 are within 9am-5pm.
Or what about:
OPEN: 10:00:00
CLOSE: 20:00:00
10 Hours total but only 7 are within 9am-5pm range.
I can calculate the total hours/minutes between the two times but not within that special range.

I have a request where i would like to get the start date/time and end date/time and flag (with an int) which hours (24 hour clock) have values between the two dates. Example car comes into service on 2013-12-25 at 0800 and leaves 2013-12-25 at 1400 the difference is 6 hours and i need my table to show
Column: Hour_6 Value: 0
Column: Hour_7 Value: 0
Column: Hour_8 Value: 1
Column: Hour_9 Value: 1
Column: Hour_10 Value: 1
Column: Hour_11 Value: 1
Column: Hour_12 Value: 1
Column: Hour_13 Value: 1
Column: Hour_14 Value: 0
As i'm working away at it i'm trying to figure out how i could use a Time Dimension table for this but dont really see much. So far i have the difference between the two times in hours (hour_diff) and the start hour (min_hour) so i would like to do something where i update the first hour (min_hour) and update columns based on the numbers of hours (hour_diff)

All,I have a table with start and end dates/times in it, and would like tobe able to calculate the number of hours represented, accounting foroverlapping records.Note that I am looking for an answer on HOW to do this--I don'tnecessarily need it to be written for me (although it would not gounappreciated!).CREATE TABLE [dbo].[session_temp] ([session_pk] [int] IDENTITY (1, 1) NOT NULL ,[date_start] [smalldatetime] NULL ,[date_end] [smalldatetime] NULL) ON [PRIMARY]GO--These values make a very simplistic example,--as they only represent one--session,so using min and max would work in this case,--but would not work if there--were multiple sessions involved.--hopefully you get the idea of what I am going for:INSERT INTO session_tempVALUES('4/4/04 9 pm','4/4/04 10pm')INSERT INTO session_tempVALUES('4/4/04 9 pm','4/4/04 10:30pm')INSERT INTO session_tempVALUES('4/4/04 9 pm','4/4/04 10:45pm')INSERT INTO session_tempVALUES('4/4/04 9 pm','4/4/04 11pm')INSERT INTO session_tempVALUES('4/4/04 9 pm','4/5/04 2am')--the query I am looking to write would return "5"--the one below obviously does not do what I am looking forSELECTSUM(CAST(DATEDIFF(ss,date_start,date_end) AS NUMERIC(8,2))/3600)FROMsession_tempThanks very much for any insight.Phil---Check out my poker-only weblog at:http://www.livejournal.com/users/chicago_phil/Download my session-tracking spreadsheet at:http://www.geocities.com/fibby70/

To calculate how many months are between the current date minus the First_Post_Date
For example
The First_Post_Date is displayed as follows following “25/07/2012”
Current date is 12-02-2014
The difference between the two dates is approx 20 months ..To make the calculation easier, it might be easier to default the day of First_Post_Date to 01 and do the same with the currentdate
So it would be 01/07/12 and 01/02/14

Hi,I have a table called Bookings which has two important columns;Booking_Start_Time and Booking_End_Time. These columns are both of typeDATETIME. Given any day how can I calculate how many hours are availablebetween the hours of 09.00 and 17.30 so a user can see at a glance how manyhours they have unbooked on a particular day (i.e. 8.5 hours less the timeof any bookings on that day), can this be done with a queryor do I have to work it out in my code?Thanks for your help

Hi,
I am trying to find the difference between two times (timeIN, timeOut)and then populate a new field called "duration of stay" with the difference.
The two times are in a table called attendance and the new duration of stay field is to be populated in a table called factAttend2
Is there an easy way to do this?
Thanks

That way I can answer quick question based on any one or twoNODEID's.Second, how would I further that to continually calculate (as statedabove)?WOuld this be a stored procedure? A trigger? A cursor?I am learning as I go here. Any help is greatly appreciated.R.

i am using this expression to get the time difference between two times.
{%Z.elapsed.time(@AK.VD.depart.date,@AK.VD.depart.time,@AK.VD.depart.date,@DV.VD.arrival.time,"hh.hh")*60} as [LOS (min)]
When Arrival time and depart time both are on same day above expression working to get the diference .
But if arrival date 2013-09-20 00:00:00.000 and arrival time 0800 and depart date 2013-09-21 00:00:00.000 and depart time 0050 when i calculate the time difference(using above expression) between these two i am getting -429.60 which is wrong. i have to get around 990.

I am setting up a monitor to alert me if an SQL job has failed in the "last 20 minutes". This should run 24 hours a day, 7 days a week. My query looks something like this.
select * from TALMAIN.msdb.dbo.sysjobhistory where job_id = '7139D5D1-CD88-46E8-8324-5D5A0D8D3A27' and run_status <> 1 and
DATEPART(YYYY,GETDATE()) = substring(convert(char(8),run_date),1,4)and
DATEPART(MM,GETDATE()) = substring(convert(char(8),run_date),5,2) and
DATEPART(DD,GETDATE()) = substring(convert(char(8),run_date),7,2)and DATEPART(HH,GETDATE()) = substring(convert(char(8),run_time),1,2)and (DATEPART(MI,GETDATE()) - substring(convert(char(8),run_time),3,2)) <= 20.
The run_date and run_time columns in msdb..sysjobhistory are stored as integers. Tried a couple of things, but I am unable to convert both of them to datetime data type. The last conditions in the above logic hold true for only "2 digit" hour and minute values.
DATEPART(HH,GETDATE()) = substring(convert(char(8),run_time),1,2)and (DATEPART(MI,GETDATE()) - substring(convert(char(8),run_time),3,2)).
What about time values like 00:05 AM and single digit time values like 1:00 AM and 9:05 AM, for example?. I pasted some sample run_date and run_time values from sysjobhistory below.
run_date run_time
2006122821510 -- 02:15:10 AM (how to get the minute count?)
2006122821510 -- 02:15:10 AM (same as above)
20061227233014 -- 23:30:14 PM (this is strt forward)
20061227233014 -- 23:30:14 PM (same as above)
200612273016 -- 00:30:16 AM (how to get minute count?)
200612273015 -- 00:30:15 AM (how to get minute count?)
Is there a simpler logic to achieve this? Hope I was clear, else let me know. Please advise. Thank you.

I'm trying to calculate the time difference between a date field and today's date in days. The date field is not mandatory and can therefore be blank. I'm trying to execute the following query:
SELECT employee_code, Civil_ID, DATEDIFF(Day, Civil_ID, GETDATE())
FROM ODEV_VIEW_Credentials_Expiry_Dates
WHERE Civil_ID IS NOT NULL AND Civil_ID != ''
ORDER BY employee_code
I keep getting the following message:
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
Warning: Null value is eliminated by an aggregate or other SET operation.
No matter what filter I use to process non-blank dates, it never works.

I have an SQL code below which removes weekends and non working days when calculating days difference between two dates:
ce.enquiry_time represents when the enquiry was logged
(DATEDIFF(dd, ce.enquiry_time, getdate()) + 1)
-(DATEDIFF(wk, ce.enquiry_time, getdate()) * 2)
-(CASE WHEN DATENAME(dw, ce.enquiry_time) = 'Sunday' THEN 1 ELSE 0 END)
-(CASE WHEN DATENAME(dw, getdate()) = 'Saturday' THEN 1 ELSE 0 END)
-(SELECT COUNT(*) FROM nonworking_day WHERE nonworking_day.nonworking_date >= ce.enquiry_time AND nonworking_day.nonworking_date < dateadd(dd,datediff(dd,0,getdate()),1))
It works but I don't understand how it works it out. I am having issues understanding each coloured piece of code and how it works together.

So I have been struggling with a way to perform inventory turn calculations in SQL. I'll start off with the formula. Basically the formula is Cost of Goods Sold over last 12 months / Average Inventory Value over the last 12 months. Short hand as COGS/AvgInventoryValue = Turns
In order to obtain the COGS value I take the Avg(UnitCost) * Sum(InvoicedQty) in the last 12 Months for Sales documents. This is represented as DOCUMENTTYPE = 2
Then divide AvgInventoryValue
To obtain the AvgInventoryValue I need to know the Quantity purchased in the 12 month period * Avg(UnitCost) + QuantityOnHand at the start of the period * Avg(UnitCost)
The purchased documents are represented with DOCUMENTTYPE = 6
The purchases will be positive since we are putting value in. The sales are negative since value is going out. I'll start with a simple example where the product is at zero Quantity On Hand at the beginning of the period.
--CREAT THE TEMP TABLE
create table #VALUEENTRY
(
ITEMNO VARCHAR (50) NOT NULL
, POSTINGDATEDATETIME NOT NULL
, DOCUMENTTYPEINT NOT NULL
[code]....
Is there another approach I should take to obtain the inventory turns?Also how do I account for periods earlier than 12 months where inventory is left over?In the sample data this item happened to be at zero inventory on hand at the start of the period. Also I believe it is my subquery's which are throwing the numbers off but I'm not sure how to isolate the subquery to just perform the result for a specific item. It is aggregating the entire table. How can I make the subquery more specific?

I have a table that contains an employee id and dates signifying time periods that those employees were working. I need to calculate anniversaries, such as 20 year, which are the sum of all periods spend working projected out to 20 years. For example,
emp_idstart_date end_date
1001 1998-01-01 2003-06-21
1002 1999-05-23 2008-03-28
1001 2004-08-19 NULL
1003 2004-10-12 2006-07-25
1004 2005-04-28 NULL
1002 2008-11-02 NULL
1003 2009-05-17 NULL
The periods in which the employees were inactive (the time period between active ranges) would push back their anniversary date, obviously. I'm only concerned with employees that are currently active (ie. the most recent record has a NULL end date). I thought about trying to use datediff to calculate the time between active periods, but I'm not sure how to go about doing it.

I am importing xml multiple times a day from a vendor. However when SSIS created the ID's for nested XML data it is not unique. So importing the first time and I get 3-4 records it looks fine. However subsequent imports all use the same ID's so it isn't unique, how do I go about changing this as I cant find anything about it.

I have a requirement to be able to calculate the transit time between international locations when I have the flight departure time and flight arrival times and departure and arrival locations.
We have a problem though, in that the datetime stored are local times, and the journeys can involve crossing the international date line in either direction, so it is possible for the arrival time to be earlier than the departure time!
To give a famous example, if you flew Concorde from London to Washington, you could depart at 10am on the 1st of June (London time) and arrive at 8.00am on 1st June (Washington time)
Even worse, you could leave Brisbane at 2.00 am on the 1st June, cross the International Date Line and arrive at San Francisco at 23:00 on 31st May!

I have a table that stores working hrs, such as
RecID,StaffID,StartDate,EndDate
17,969,2015-05-18 00:00:00.000,2015-05-18 06:00:00.000
18,969,2015-05-18 18:00:00.000,2015-05-19 06:00:00.000
19,969,2015-05-19 18:00:00.000,2015-05-20 06:00:00.000
20,969,2015-05-20 18:00:00.000,2015-05-21 06:00:00.000
21,969,2015-05-21 18:00:00.000,2015-05-22 06:00:00.000
22,969,2015-05-22 18:00:00.000,2015-05-23 06:00:00.000
23,969,2015-05-23 14:00:00.000,2015-05-24 08:00:00.000
24,969,2015-05-24 22:00:00.000,2015-05-25 00:00:00.000
So working times can go over midnight, there can be more than one working period in a day etc.
For this staff member the summary of the weeks work will be
18/05/2015 - 12 hrs
19/05/2015 - 12 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 12 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
Now for the complicated part, a person can take absence(sick,holiday,other) for any part of a day or whole day(s). For these absence periods only the worked time on that day needs to be negated off, not the whole period of time.
So for example
If this person
had a days holiday on the 22nd, shown in the HOLIDAY table as
StaffID,DateFrom, DateTo
969, 22/05/2015 00:00:00.000,22/05/2015 23:59:59.000
A Leave of Absence on the 20th, shown in the LEAVE table as
StaffID,DateFrom, DateTo
969,20/05/2015 12:00:00.000,20/05/2015 16:00:00.000
And was off sick on the morning of the 19th, shown in the SICKNESS Table as
StaffID,DateFrom, DateTo
969, 19/05/2015 00:00:00.000,19/05/2015 11:59:59.000
Now the Summary table should now show
18/05/2015 - 12 hrs
19/05/2015 - 6 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 0 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
The 'Leave of Absence' on the 20th had no effect on the total for the day as it was between planned work times. how to do this within T-SQL, as simple as possible as I've got to had this code over to other staff members to maintain, who have not had much SQL experience yet?
I've tried doing it as a temp table, with dual insert/select commands, splitting the times over midnight, which partially worked but missed some of the combinations.

Hi,What is the best way to model this: Assume I have two objects: Agencyand Publisher, and both have a 1-to-n relationship to Employee. This isa true 1-to-n relationship, as each Employee can only work for oneAgency or one Publisher. Let's assume further that I cannot introduce asupertype (e.g. Employer) which holds the 1-to-n relationship.My preferrd solution is to have a foreign key in Emplyee that caneither link to a primary key of Agency or Publisher (all my primarykeys are 64-bit IDs that are unqiue across the database). However, nowI won't be able to map a bi-directional association, without indicatingin Employee whether this is an "Agency" or "Publisher" relationship(ala <ANY>).My other option is to use two tables, AgencyEmployee andPublisherEmployee, which can then be linked as traditional 1-to-nbidirectional associations.What do you guys consider best practice in this situation?Cheers,Jen

I'm really new to SQL and looking for advice.
I'm going through the basics I don't mind doing my own research but I have an issue that needs attention and is beyond my current level.
I'm looking for a way to have any data entered into one database automatically copied to an archive database running on another machine. Items deleted in database one would be retained in database two. Database one would be clean and efficient and only reflect currently necessary information. Database two would grow indefinitely as an archive of what had/does exist in database one.
I'm sure this is quite mundane but I'm not sure what key words I'm looking for. Is there a title for this process?
Is this possible from within the SQL management studio or should I start those videos under the developer section?
I'm in the tall grass. Any pointers appreciated.
Both servers are Server2003 with SQL Server 2005 Standard Edition /Sp2

ive got a tough one for everyone this time!
i am trying to get a page up that enables me to enter a number into a box on a form, which then on clicking of a search button, queries the database, and returns 2 other fields that relate to the number found in the database, in an ASP datagrid.
the easiest way to do this would be to use OLEDB or ODBC, but the host i am using doesnt support either of them, and so i am trying to use their code, something using OBJDB, but to no avail. frankly, their code is rubbish, and im not sure how to go about doing the above.
i would be very grateful if someone could help me out with this problem,
thanks,

:eek:
I'm having a brain not functioning day - well who am I kidding - more like a year :rolleyes:
I need some help with some sequence numbering and cannot even get my head around the logic I want to use, let alone the actual code.
I have a dataset with 3 fields:
Area
ID
RefNo
This table contains a list of employee ID's by Area and each employee has a RefNo (counter) in each area.
The data comes from 2 different sources and is combined in this table. Some employees had no RefNo already assigned to them so I have entered their RefNo as 10000 in order to ensure they are sorted at the bottom of the list.
The ID's that have RefNo's have to keep the one they have. Therefore, I need to create RefNo's for the ones that currently have RefNo 10000.
These numbers I create have to follow on from the highest RefNo for the Area.
For example:
Area ID RefNo
A Z 1
A Y 2
A X 3
A W 10000
A V 10000
B N 1
B O 10000
B P 10000
So, for Area A, ID's W and V would have to be assigned RefNo 4 and 5, and for Area B, ID's O and P would have to be assigned RefNo 2 and 3.
Hope this makes sense to all.
BTW, am using SQL 2000 at the moment.
Thanks in advance for any help!

I would like to calculate difference between end_date and current date in Months.And also how we can calculate the sum of difference in months between start_date and end_date for each ID?

INSERT INTO datedifference VALUES (30,20051202,20101031)

I have a table with a list of jobs along with their start and end datetime values.
I am looking for a function which will return the time taken to process a job using a start date and an end date. If the date range covers a Saturday or Sunday I want the time to ignore the weekends.
Example
Start Date=2014-05-15 12:00:00.000
End Date=2014-05-19 13:00:00.000
Total Time should be: 2 Days, 1 Hour and 0 Minutes
