SQL 2012 :: Calculating Elapsed Time Between Records?
Oct 29, 2015
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,
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 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 am trying to calculate the time difference between the value in the row and the min value in the table. So say the min value in the table is 2014-05-29 14:44:17.713. (This is the start time of the test.) Now say the test ends at 2014-05-29 17:10:17.010. There are many rows recorded during that start and end time, for each row created a time stamp is created. I am trying to calculate the elapsed time and have it as a row in the results.
min(timestamp) - timestamp(value in row) = elapsed time for that test where Channel = '273'
Here is the table DDL
CREATE DATABASE SpecTest; USE SpecTest GO
CREATE TABLE [dbo].[Spec1]( [Spec1ID] [int] IDENTITY(1,1) NOT NULL, [Channel] [int] NOT NULL,
I have a data set like so:UTC_TIME Timestamp NodeID Message FlagLineStation11/19/2005 10:45:07 1132397107.91 1 3 5 1028103411/3/2005 21:05:35 1131051935.20 2 3 5 1009104311/25/2005 21:12:16 1132953136.59 3 3 5 10371049I added the UTC_TIME column in as aconversion of the unix timestamp inthe TIMESTAMP column.Keeping things simple and straightforward, I need to be able tocalculate the difference from one record to the next (ordered byTIMESTAMP or UTC_TIME) and output the result into another column in thetable.NODEID is the unique id.First, what is the function to do so if, say, I only wanted tocalculate the difference between 2 records as just a basic SELECTstatement. 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.

It seems to work fine with one million records.
Each primary key is unique, but the begindate is non-unique, and i guess even if i use datetime2 and add nanoseconds, from what i have read, there is a chance that i could have a duplicate datetime since the date is imported via XML from multiple sources.
Ok, so I have some horribly convuluted SQL that I would love to optomize. I'm not happy leaving it in it's current state, that's for sure!
I'm currently working on our test bed servers, so obviously my stats are out because of the "crap-ness" (yes, that's the technical term) of the hardware, but still, it should NEVER need to take this long!!
Basically, the issue arises in the nasty join to the career table (one employee can have multiple career lines). Just to make things complicated, employees can have any number of career records on any given date, these can even be input for future career events. The following SQL picks out the latest-current career date for each employee based on the career_date being <= GetDate() and the date of entry for this date being the greatest.
From the above we want to return 2007-01-01 | 2006-05-05 13:54:18.000

Any advice on what I can do to optomize?
Oh judt to point out that "employee" is a view on the "Table 'people'." EDIT: I know it's pointing out the obvious, but I'm pulling out the managers "DN" from AD_Import based on the manager_number and employeeNumber matching.
I need a formula to calculate the time (let's say in minutes) between two dates/times. The problem is that I have to exclude the time between 06 PM and 06 AM and also exclude the time in the weekend (Saturday and Sunday). I will use this in a couple of reports made in Reporting Services. If anyone have an algoritm that could be modified for this and is willing to share this I would be very grateful. Many thanks! /Per Lissel
I want to know how long does each of the script piece take. So how can I keep the records of time spent and save them as a file or save them into a table?
I am developing a form for a mortgage company. There can be any number of borrowers on a given loan, and the business has asked that this form return only 2 borrowers at a time for a loan. For example, if there are 3 borrowers for a loan, they want the first copy of the form to print the first 2 borrowers and then another copy of the form to print the 3rd. No matter how many copies are printed, they want the borrower information to be labeled as 'Borrower1' xyz and 'Borrower2' xyz. Also, there will be a LOT more fields returned on the real form, so the sample information below is very simplified test data.
I don't want that 2nd record to return. This result is what makes me think of gaps and islands, but I don't know if the 2nd record is really an island since it's (1) not stored this way...it's returning this way because of the query and (2) it's not sequential data..I tried restricting this by putting this into a CTE and then returning only the odd numbered records like I have below. This runs pretty quickly when dealing with one loan. But...I am concerned that the CTE will be slow when we run batches of loans.
Attempt with CTE: --With CTE ;WITH cte AS (SELECT Borrower1 = BorrowerName , Borrower2 = LEAD(BorrowerName) OVER(ORDER BY BorrowerOrder) , RowNumber = ROW_NUMBER() OVER(ORDER BY BorrowerOrder)
[code]...
Is there a better, cleaner way to do this? Or is the CTE the best way to go?
I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField from MyOptions where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField from MyTimetable where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.
Hello, I am fairly new to this, but I need to write a query that calculates whether an order made a shipping cutoff based on creation time, and when it actually shipped, based on local customer time. All times in the table below are central time. Heres where it gets complicated for me. If the order was created after 8:00am local customer time the same day, and shipped prior to 5pm local customer time, it would be considered a pass, or a 1. If an order was created after 8am local customer time, BUT didnt ship until AFTER 5pm local customer time, it would be considered a failure or a 0. And to complicate things even more, if the order is created after 5pm local customer time, the order create time would be treated as it was created at 8am local customer time the following day local customer time, and would need to be shipped prior to 5pm local customer time that day. Would CASE be appropriate for this? Or am I thinking wrong? Any help would really be appreciated!!
I have a table called Tickets which contains ticket information for a machine. Each machine can have more than one ticket number opened at the same time. The ticket number contains start date/time and end date/time of the ticket. Thereefore the table looks something like this:
I want to be able to calculate total duration time(in hours) that EACH MACHINE had a ticket open...but here is the tricky part. The total duration time that a machine had ticket open has to encompas any tickets that may fall in the same time period. For example: If Machine A has a ticket open at 8:30 and the ticket is closed at 10:00. Meanwhile, Machine A had another separate ticket open at 9:30 which was closed at 10:30. In this case, the total duration time for this machine would be from 8:30 to 10:30 for a total of 2 hrs duration time.
Can anyone help me get started in tackling this problem or provide any examples?

Hi guys, I am having difficulty calculating the time duration between receiving process to shipping process. I have a table that consists of: Order#, Processes, Time_In, Time_Out. Order# can be 1, 2, 3, 4, 5. While at the same time Order# 1 can go through more than one process, i.e.: Receiving, VisualTest, MechanicalTest, ..., Shipping. Every Order# does not necessarily goes through all processes, but surely they will go through receiving process and shipping process. For each process we will have recorded time when the order# comes in and when it finishes with each process. I need to calculate the length of time from Time_In from Receiving to Time_Out in Shipping.
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

Here is my problem:
I have a table like the following in SQL Server 2005:
order | taskid | main_person | temp_person | start_assign_date 1 | 3 | John | John | 2008-01-01 10:20:22 2 | 3 | John | Joe | 2008-02-05 15:20:22 3 | 3 | John | John | 2008-02-07 20:25:20 4 | 6 | Joe | Joe | 2008-01-01 10:20:22 5 | 6 | Joe | Mike | 2008-02-01 10:20:22 6 | 10 | Doug | Doug | 2008-01-01 10:20:22 7 | 7 | Russ | Russ | 2008-02-01 11:20:22 8 | 7 | Russ | Mike | 2008-02-08 12:20:22 9 | 7 | Russ | John | 2008-02-10 20:05:12
It was made to record who was in charge of a specific task at a specific time. Each task has its own main responsible person and some substitutes for that person as Temporary Persons (who did the task while main person was away). The Main Person's name is in the temp_person column when he is doing the task by himself.
I'd like to generate a report that shows: - in a specific time period - which persons were in charge of a specific task and - for how long
Something like this:
From 2008-##-## to 2008-##-## Task 3 - John - 15 days Task 3 - Joe - 5 days Task 6 - Joe - 18 days Task 6 - Mike - 2 days Task 10 - Doug - 20 days
I have some ideas to do that when there are both start and end dates for every record but I couldn't find a way to use the next assignment start date for each task, as the end date for its previous record (in that task group) to calculate the duration for that record.
I can group the tasks and users and put them in the chronological order but I can't indicate the next start date as the end date for the previous record (in specific task group) to use the date difference functions.
Hi all As you know when you run a piece of TSQL scrypt in Query Analizer at the bottom of the page , sql-server will show you the Time of completion of your code....is there any way to capture this time from SQL-Server environment and use it in the Front-End Application to inform the user?

I have two tables and they have a foreign key relationship. It will be a 1 to Many realationship. Table1- the primary key table has the following columns ContentID - int identity field DateAdded- datetime Table2 - The foreign key table, has the following relevant fields FK - int foreign key version - int When an initial record is added there is a record added to each table. The ContentID in Table1 will match the FK field in Table2. Then a user will be able to "edit" the record in Table2, but instead of writing over the record that is already there, a new record will be added to Table2. I would like to calculate the version field where each time a record is added for the particular ContentID/FK it adds 1 to the last version that was added to that particular ContentID/FK. Does that make sense. I am trying to implement some type of revision tracking for my CMS that I am building and this is the only way I can come up with because my client is worried that somebody will go in and make incorrect changes to their site and they want to be able to roll it back to a previous version. I would appreciate any ideas. Thanks, laura
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.
I am using MS SQL Server 2000. I have 4 text fields 1. event begin date 2. event begin time 3. event end date 4. event end time I have to find the day and time difference in months days hours and minutes between the event begin date & time and the event end date & time – The event begin date and event end date are char(8) & event begin time and event end time are char(4) – with military time. I would need to combine the event begin date & event begin time to get the event begin date & time and the same for the event end date & time. If the values of the 4 text fields are event begin date = ‘20070207’, event begin time = ‘2015’, event end date = ‘20070208’, event end time = ‘0105’, the difference should be 0 month 0 day 4 hours 50 minutes. Can somebody please help with MS SQL Server 2000 syntax?
I have a requirement to calculate the total outage time, based on logged fault tickets, of network nodes. Basically, multiple tickets may be raised for a single node and those tickets could overlap or sequence over a given period; the task here is to calculate the total time (hh:mm) of the outage in the period.
Ex:
3 tickets raised for a node outage over, say, a 48 hour period. Ticket 1 (spanning a total of 5 hours) overlaps with ticket 2 (spans 3 hours) by 1 hour; ticket 3 starts 5 hours after ticket 2 and spans 1 hour. Total outage time on the tickets is 7hrs + 1hr (T1+T2 minus the 1hr overlap) and the full time of T3.
In summary, it's calculating the total ticket time, allowing for overlaps of tickets, etc.
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.
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.

We have a proc that runs nightly which updates stats. For each database it will run dbcc updateusage on each table, then then sp_updatestats on the database itself.
This process normally takes about an hour, but recently the time has gone up dramatically.
I am looking at ways of making the run faster. One suggestion was to split the work and have it run in parrallel, with multiple procs all doing the same job but on different databases. So for example, I could have a proc that would determine which databases would take the longest to process, and then call 3 different copies of our update proc, each getting a different set of databases to process.
If I went this route, how could I determine which databases would take the longest to complete this process? I'm investigating determining this from sysindexes' rowmodctr, or maybe just database size?
Any suggestions on how I could get an estimate of which dbs would be the most costly to update stats? This is for SQL Server 2000.
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?
