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

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.

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 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.

It has been a while since I have used SQL server and require to show a time difference between a start and end time, with only 1 date to determine these times
SQL
select
Arrival_date
locationdate as LocDate,
locationid as Loc_ID,
locations.loc_name as Location_Name
from current_locations
left outer join locations on
locations.loc_id = current_locations.location_id
where current_locations.Attend_ID = '1234567'
Results

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'm fairly new to MS SQL, but I'm trying to query the time elapse between two dates. Example below...
Select
dbo.res.book_date,
dbo.res.arrive_date,
Cast (dbo.translog.systemdate as datetime)
From
dbo.res
Where
dbo.res.resid > '500'
The third line is where I need help with a statement. I need the elapse time. Ex. if the book date is 20050820100000 and the arrive date is 20050820120000, I would like the third Select statement to return 2:00 hours or something similar. Thanks.

I have a table in my sql server that calculates renewal dates for me, that date is based on the final suit date. The table has the ssn, and the FinalSuitDate its in a one to many relationship with the employeetable.
the Finalsuit table is suppose to calculate the renewal dates(which I'm trying to do in a query) my original expression in access was using dateserial FirstRenewal: DateSerial(Year([FINALSUITDONE])+2,Month([FINALSUITDONE])+1,Day([FINALSUITDONE])=30), but sql does not recognize that.
For Example
If the Finalsuit is 12/01/2000
then the renewal would be 12/31/2002
the renewal are to be done on the last day of the month and two years from the finalsuit date. Problems is I'm having problems doing this in sql servers query?
Can someone out there help please

I have a project where I need to populate a table with a Begin and an end date based on another field with in the table. my example is that the other field will have a value of "monthly" I want then a record to be entered on the table with a begin date of November 1 and the en date as November 30th. I want this record to get populated only on business days. my thinking is a stored procedure that runs daily and only creates a record at a time. i am thinking if the user selects weekly the dates populated would be november 1 = begin date and Novemeber 2nd = end date
i want to fill out a current month at a time as if the account closes i will not need the extra cases.
thanks

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'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.

Hello,
Can anyone out there tell me if there's a simple way to calculate the number of week days between two dates in TSQL? Need it to calc. average turnaround times, excluding weekends. Can do it v. easily in VB, but gets a little more tricky in TSQL as there's no way to return the number of Sundays and Saturdays between the two dates. Any help much appreciated !

Hi Engine room.
I want to automatically populate an alternative date column with hijri (Arabic) dates. So I will have two date columns in my datawarehouse table, one is for gregorian dates, the other for the equivalent in Hijri - a bilingual date system if you like. Now I guess I could do it in the SSI ETL tool and use Julian Dates, but the problem is storing the resulting value. - what data type should I use for hijri dates?
The dates can be input by the user in either format, which means the alternate date has to be populated.
Eventually I hope to make a bilingual system, I don't understand the user-defined types or how to define them, but I suspect they could be used in someway to help. Why am I doing this? - well eventually I hope to populate a cube for analysis and deliver a dual-language-dashboard using the new CTP3 stuff.
Any suggestions on how I can make this dual-date system? - with a view to making a bilingual system eventually.
adv(thnx)ance..Mark.

This function will return working hours between given 2 dates. This function assumes that the break is between 9:45 AM and 10 AM and that Lunch is between 12:30 PM and 1 PM. This function also assumes that the working hours are between 7:30 AM and 4 PM. There is a section for public holidays there. We have a table for that you might not so that piece needs to be fixed.

Ok, so I've been struggling with the logic behind this one for a while, so I thought I'd ask you guys for some ideas :)
Basically, I have the following table structure
Employee(employee_number, continuous_start_date, ...)
The problem lies in working out a summary of service categories (0-6months, 7-12months, 13-24, 25+).
I can work out the length of service in months with the following code
SELECT DateDiff(mm, continuous_start_date, GetDate()) AS 'Service in months'
FROM employee
So the first stage is to summarise the length of service into groups as mentioned above.
Then the final stage is working out how many people are in each group!
Hope I have given enough information - and please do not post a full solution - just some hints on how to get the desired result ;)
Thanks later, and in advance :p

Hi, i'm trying to calculate the number of days between two dates, but within an UPDATE statement, so far I can't wrap my head around how I can update a field with the number of days.
I was thinking something like
Code:
Update #ClaimMaster
Set covered_days = (then insert select statement that subtracts the two dates)
Does that make any sense?

On the report I have used the grouped by clause on 'Issue Reference #'. I want one more column which would calculate the difference between two consecutive Activity Date/Time of the same reference #.
e.g. Time difference between 4521404 and 4521405, 4521405 and 4521406, 4521406 and 4521473 etc. Please note that the difference between 4521412 and 4522575 will NOT be calculated since they are from different Reference Numbers.

Hi all,
I have a table named Orders and this table has two relevant fields: CustomerId and OrderDate. I am trying to construct a query that will give me the difference, in days, between each customer's order so that the results would be something like: (using Northwind as the example)
...
ALFKI 25/08/1997 03/10/1997 39
ALFKI 03/10/1997 13/10/1997 10
ALFKI 13/10/1997 15/01/1998 94
ALFKI 15/01/1998 16/03/1998 60
ALFKI 16/03/1998 09/04/1998 24
...
At the moment, I have the following query that I think is on the right track:
��
SELECT dbo.Orders.CustomerID, dbo.Orders.OrderDate AS LowDate, Orders_1.OrderDate AS HighDate, DATEDIFF([day], dbo.Orders.OrderDate, Orders_1.OrderDate) AS Difference FROM dbo.Orders INNER JOIN dbo.Orders Orders_1 ON dbo.Orders.CustomerID = Orders_1.CustomerID AND dbo.Orders.OrderDate < Orders_1.OrderDate GROUP BY dbo.Orders.CustomerID, dbo.Orders.OrderDate, Orders_1.OrderDate, DATEDIFF([day], dbo.Orders.OrderDate, Orders_1.OrderDate) ORDER BY dbo.Orders.CustomerID, dbo.Orders.OrderDate, Orders_1.OrderDate
��
However, this gives me too much data:
��
ALFKI 25/08/1997 03/10/1997 39
ALFKI 25/08/1997 13/10/1997 49
ALFKI 25/08/1997 15/01/1998 143
ALFKI 25/08/1997 16/03/1998 203
ALFKI 25/08/1997 09/04/1998 227
ALFKI 03/10/1997 13/10/1997 10
ALFKI 03/10/1997 15/01/1998 104
ALFKI 03/10/1997 16/03/1998 164
ALFKI 03/10/1997 09/04/1998 188
ALFKI 13/10/1997 15/01/1998 94
ALFKI 13/10/1997 16/03/1998 154
ALFKI 13/10/1997 09/04/1998 178
ALFKI 15/01/1998 16/03/1998 60
ALFKI 15/01/1998 09/04/1998 84
��
So, do any of you have any ideas how I might achieve this? I know how to do it using a stored procedure, but I am trying to avoid that; I��d like to do this in a single query.
Thanks for any help you have to offer,
Regards,
Stephen.

Its early in the morning and I am struggling with an easy one.
I have a calculated field in a report which displays the difference between 2 dates. The value that is returned is a number which I can then format to display difference like so 'Days.hh:mms'
I need the diffence between the dates to be expressed in hours, minutes and seconds only. eg '36:45:12'
It would also be usefull if I could build a parameter in to the query which would allow me to discount days selected by the user (Using multi select drop down in day format i.e 'Monday', 'Tuesday', etc)
Any Idea's?

I have a field called 'LOG_COMMENTS' in a table named T_PRODUCTION_WORK_LOG.
In the 'LOG_COMMENTS' whenever a request is placed on hold comments are added by the application, such as 'Status changed from Open to On Hold' and 'Status changed from On Hold to Open' along with a 'LOG_DATESTAMP' field. A request can go on and off Hold multiple times, how do I determine the days a request is On Hold?
I know I can use the sql function DATEDIFF ( datepart , startdate , enddate ), but how do I account for the possiblity that the request was On Hold more than once? And how would I get LOG_DATESTAMP' times for 'LOG_COMMENTS' that contain 'Status changed from Open to On Hold' and 'Status changed from On Hold to Open''?

I have a need to display the difference between two dates, a start date and a end date in the format HH:mm where the hours could be greater than 60.
For example:
Start Date - 30/01/2007 09:00:01
End Date - 01/02/2007 20:40:04
When i use the following code (=Fields!dateend.Value - Fields!DateStart.Value) i get 2.11:40:03 which i can easily understand, but the customer wants it as above!
I would like to be able to get it to be 59:40:03.
Any help would be much appreciated.

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!
