Calculate Date Difference Excluding Dates

Aug 27, 2012

I have already seen stored procedures that can calculate a difference in dates, excluding the weekends. Any extension of such a SQL query to exclude not only weekends, but other dates as well. We have a table of "holidays" (not necessarily standard holidays), and I am wondering if there is a way to exclude them from the calculation.

Calculate Difference Between Two Dates

Oct 18, 2006

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


Update #ClaimMaster
Set covered_days = (then insert select statement that subtracts the two dates)

Does that make any sense?

Date Difference For Multiple Dates

Jun 18, 2014

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''?

Does anyone know how to write code to tell the amount of days between 2 dates excluding Saturday and Sunday.
Datediff will tell me the total amount of days and I guess I need some logic to look at the startdate and manipulate the total after the fact.

Any thoughts or solutions out there?

Calculate Difference Between Two Rows

May 15, 2006


i have a matrix, and in that matrix i need to have one column which calculates the percentage change between a value on the current row and the same value on the previous row.

Is this possible? The RunningValue() function isn't of help as it can't help me calculate the change between two rows, and Previous() doesn't work in a matrix (why???!!!!!). Also calculating this as part of the query isn't possible as there is a single row group on the matrix, and the query is MDX.*



*for those who are curious, the matrix is showing data an a per week basis, the row group is snapshot date, i am trying to measure the change in sales at each snapshot.

Calculate First And Last Dates From DATEPART

Aug 1, 2000

I'm kinda stumped....
How would one find the first and and last date in a date range defined by a DATEPART, regardless of the parameter?

For Example...
DATEPART(wk,7/31/2000) would return 7/30/2000 and 8/5/2000
DATEPART(qq,7/31/2000) would return 7/1/2000 and 9/30/2000
DATEPART(yy,7/31/2000) would return 1/1/2000 and 12/31/2000

SQL 2012 :: Calculate Time Difference For Consecutive Rows?

Jul 2, 2015

I have a table like this.

([S_ID] varchar(7), [S_ACTV_CODE] varchar(4), [S_USER] varchar(5), [S_DATETIME] varchar(19), [S_ACT_IND] int)
('AAA-111', NULL, 'USER1', '2015-06-15 00:21:06', 0),
('AAA-111', '2', 'USER1', '2015-06-15 00:21:07', 0),


Basically I want to calculate the time spent by S_Users on a particular S_ACTV_CODE:

- S_ACTV_CODE_PREV means the previous active records.

- S_START_TIME is the time of S_DATETIME when a S_ACTV_CODE starts

- S_END_TIME is the time before a S_ACTV_CODE changes to another S_ACTV_CODE

- For the first record, S_ACTV_CODE is null, so there is no S_ACTV_CODE_PREV, so S_ACTV_CODE_PREV is NULL

- For the second record S_ACTV_CODE has some value, but S_ACTV_CODE_PREV is NULL for first record. So second record S_ACTV_CODE_PREV is also NULL

- For the last record (means S_ACTV_IND = 1), the user is currently working on it and S_ACTV_CODE is not changed. So S_END_TIME is a open time and we want to keep it as NULL

So the result should be as below:

AAA-111 NULL NULL USER1 2015-06-15 00:21:06
2015-06-15 00:21:07 1
AAA-111 NULL 2 USER1 2015-06-15 00:21:07
2015-06-17 03:20:33 183566
AAA-111 2 4 USER2 2015-06-17 03:20:33

I was wondering how you perform a select statement based on a specific date that will show all the records no matter which times belong to the specific date.

I have been having trouble with this one when using a single date, I think this is because of the time property as no records are displayed.

Thanks for any help.

SQL Server 2014 :: Calculate Running Difference In Values Between Days?

Oct 13, 2015

I am trying to write a query to calculate the running difference between data on different dates. Below is what my table of data looks like. Basically I want to calculate the difference between the total_completed for each state and date.

08/27/15CA 19,952
09/11/15CA 26,336
10/02/15CA 35,444
10/08/15CA 38,278

below is what I am trying to achieve:

08/27/15CA 19,952 0
09/11/15CA 26,336 6,384
10/02/15CA 35,444 9,108
10/08/15CA 38,278 2,834

below is my code (I almost have what I need) I just can't figure out how show 0 as the completed_difference for the first Date for each state since there is no prior date to calculate against.

LEFT JOIN TOTAL_COMPLETED T2 ON T1.[Date] = T2.[Date] AND T1.States = T2.States
