SQL Server 2012 :: Add Business Days To A Date Using Calendar Table
May 12, 2015
I have a date that I need to add 'n' number of business days to. I have a calendar table that has a 'IsBusinessDay' flag, so it would be good if I was able to use this to get what I need. I've tried to use the 'LEAD' function in the following way;
SELECT A. Date, B.DatePlus3BusinessDays
FROM TableA A
LEFT JOIN (Select DateKey, LEAD(DateKey,3) OVER (ORDER BY datekey) AS DatePlus3BusinessDays FROM Calendar WHERE IsBusinessDay = 1) B ON A.DateKey = B.DateKey
Problem with this is that because I am filtering the Calendar for business days only, when there is a date that is not a business day in TableA, a NULL is being returned.
Is there any way to do a conditional LEAD, so it skips rows that are not business days? Or do I have do go with a completely different approach?

I have a calendar table against entire year 2015 with each day with 2 flag,
1. WK_DT_IN == except Satarday and Sunday, value is "Y", for Sat/Sun, value is "N"
2. HOL_DT_IN == value will only be "Y" only for holiday, example for '2015-01-01' date, it's value is "Y"
DECLARE @CAL TABLE (CAL_DT DATE, WK_DT_IN CHAR(1), HOL_DT_IN CHAR(1))
INSERT INTO @CAL VALUES ('2015-01-01', 'Y', 'Y'), ('2015-01-02', 'Y', 'N'),('2015-01-03', 'N', 'N'),
('2015-01-04', 'N', 'N'), ('2015-01-05', 'Y', 'N'), ('2015-01-06', 'Y', 'N'), ('2015-01-07', 'Y', 'N')
We have a given date, example '2015-01-01', I need to find out a date after 2 business days? I can think of loop, but will it work.
I need to exclude date which having HOL_DT_IN = "Y" and WK_DT_IN = "N".

I created a dbo.Calendar table that stores dates and a work day flag (1=work day, 0=non-work day) so I can use it to calculate the next business date from a date using a function. I'm using a while group to count only the work days and a couple other internal variables but I'm not sure if I can even use them in a function.
Assuming Sats & Suns are all non-work days in April 2014, if my @WorkDays = 10 for 10 work days and my @DateFromValue - 4/1/2014, I would expect my return date to be 4/15/2014.

I need to create a week calendar from date in SQL 2012. Week date starts with Sunday regardless if first Sunday or last Sunday overlaps with previous or next month. For example, the first week in Sep 2015 starts on Sunday 8/30/2015 and ends in 9/5/2015. Too, the last week of Sep 2015 starts on 9/27/2015 and ends on 10/3/2015. Here is the final format:
WeekStartdate WeekEndDate WeekName
8/30/2015 9/5/2015 Sep_Week1
9/6/2015 9/12/2015 Sep_Week2
.....
9/27/2015 10/3/2015 Sep_Week5

I have a query to run a report where the results has a column named “Due Date” which holds a date value based on the project submission date.Now, I need to add 4 columns named, “45 Days Expectant”, “30 Days Overdue”, “60 Days Overdue” and “90 Days Overdue”.I need to do a calculation based on the “Due Date” and “System (I mean default computer date) Date” that if “System Date” is 45 days+ to “Due Date” than put “Yes” in “45 Days Expectant” row.
Also, if “Due Date” is less than or equal to system date by 30 days, put “Yes” in “30 Days Overdue” and same for the 60 and 90 days.how to write this Case Statement? I have some answers how to do it in SSRS (Report Designer) but I want to get the results using T-SQl.

I'm looking for a DATEDIFF function which will give me the
BUSINESS days difference between 2 dates.
e.g: datediff(day,'08/08/2007','08/14/2007) would normally result in 6 (i think), however in business days this would be 4.
is there such a function?
Thx

I need a function to count business days (exclude Sat, Sun) that I can call within a view. I would rather not build a "calendar table" this will be used ongoing for years into the future.
Does anyone have anything like this they could share? If there is another source you could direct me to I would appreciate that as well.
TIA

I have stumbled upon a sql question I cannot answer. I am looking for the following SELECT sql statement:
Basically I need a way to get "5 days ago from today". BUT, the trick is that there is a table called tblnoworkday with contains weekends and holidays and those dates cannot count. So basically what I am really trying to get is "5 Business days ago from today".
So it would basically do this for an query input date of '4/9/08'. If the table is called TblNoWorkday and contains the following records:
...
2008-04-06 00:00:00.000
2008-04-05 00:00:00.000
...
This is the last 5 business days then: (not in the table)
4/9/08
4/8/08
4/7/08
****weekend****
4/4/08
4/3/08
The query should return just 4/3/08. The problem is 4/3/08 doesn't exist in the database since the database only contains the no work days.
Any ideas on how to do this in a simple query without having to create another table with the valid working dates?
Thanks Before Hand,
Adiel

Hi and Thank you in advance
I am trying to find a away to calculate the number of business days between two dates. In other word, I do not want to count Saturday nor Sundays if those days are between the two dates.
Example
if Date1 = 11/26/1999
Date2 = 11/30/1999
the DateDiff(dd,Date1,Date2) the result should be 2
I need to do this against a table which might not have a lot of records, but I also need to not count Holidays if they fall within the two Dates.
Thank you in advance

I am trying to get a cumulative count of business days. I have a column in my date dimension BusinessDayInd which is 'Y' or 'N'. I have been trying to create a calculated column in the cube but have not been successful yet. I think I'm close with this:
COUNTROWS(FILTER(DATESMTD(PostingDate[Posting Date]), PostingDate[BusinessDayInd] = "Y"))
However, this is giving me a count of calendar days for all business days and null for non-business days. How do I apply the filter to DATESMTD? I've tried many iterations of this using CALCULATETABLE, CALCULATE, and FILTER. All are giving me the same result.
What am I doing wrong?

I am trying to create a calendar style report that will have 12 months (as columns) and store opening listing in rows. I have created a matrix, but the problem that I have is that the store opening listing displays in the right period, but they are not in any order. I would like to have the openings always on top, right under the header in the matrix. Now I have them scattered randomly all over the matrix. I tried numerous way of sorting and that does not work.
I am attaching a sample of what I would like to accomplish (months are columns).

I need to create a table which holds date information for our financial year.
I have all the dates between now and 2045 and the start of the week and the end of the week. What I also have is the first sunday of the previous week in the spreadsheet too.
Please see below attachment
What I need to autofill once I import these three dates into a database is the week and the month.
The difficulty surrounding the month is that, we start a new month on the FIRST Sunday of the month.
So dates 07/04/14 to 04/05/2014 would be month 1.
Month 2 would begin on 05/05/2014 as it is the day after the first Sunday of the month, and so on....Month 5 would start on the 04/08/14.
Need to script something that would automatically calculate the week and month for me on the basis on above, if I have the start date, end date and 1st sunday already in a table?

I have a table with EmployeeID, StartDate, and EndDate with a PK of EmployeeID, StartDate. How can I check to see that there's no overlap for StartDate and EndDate for a given employee? That is, on any given day there must only be 1 row for an employee where Getdate() is Between StartDate and EndDate. For an active employee their EndDate is set to 06/06/2079.
I've tried it using Row_Number() with Over() but am returning too many rows indicating overlap when none exists.

We have a database and have 6-7 growing tables. All the tables have Primary and foreign key relation. I want to do partition based on the date column.
I need 3 partitions
First partition has to hold present data
second partition need to hold the previous year data (SAS storage)
Third partition need to hold all the old data and need to be in the archive database
I understand that first we need to disable the constraints (Indexes PK & FK)
Then create partition function and partition schema
Then Create the Constraints again

I have a table (we will cal DateTable) with several (20) columns, each being a date type. Another table's (Project) PK is referenced in the DateTable.
I am trying to write a query that will pull all dates for a specific project from the DateTable if they meet certain criteria(i.e. if the date is <= 7 days from now.
I started with a normal select statement selecting each column with a join to the project and then a where clause using
(DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()) OR (DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE())) ...
The rest of the columns(all with OR between them).
The problem with this is that because I am using OR once one of the dates meets the criteria it selects all the dates that are associated with the project. I ONLY want the dates that meet the criteria and don't care about the rest.
Obviously because I have all the columns in the select statement... So I need something like
Select ALL Columns
from DateTable d
Join Project p
where p.ProjectID = d.ProjectID AND only dates BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()))
