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"
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:
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 have already created a table name 'tblHolidays' and populated with 2014 Holidays. What I would like is be able to calculate (subtract or add) number of days from a date. For example subtract 2 days from 07/08/2014 and function should return 07/03/2014.
CREATE FUNCTION [dbo].[ElapsedBDays] (@Start smalldatetime, @End smalldatetime) RETURNS int AS BEGIN /* Description: Function designed to calculate the number of business days (In hours) between two dates.
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.
I have to produce a report to calculate no of days based on user input start date and end date.
say for eg: in the tables I have emp name user 'Phani' started work from - EStart 20/11/2014EEnd 10/01/2015 - total days --datediff within his work period he did different roles:
PhaniMarketing (prSt Date) 20/11/2014prE date (28/11/2014) Total 9 days PhaniAdmin (prSt Date) 29/11/2014prE date (20/12/2014) Total 22 days PhaniCRM (prSt Date) 20/12/2014prE date (10/01/2015) Total 22 days Total days 53 Days for this :
[code]...
HOW CAN I USE Case statement to calculate days for given start date and end date. I have to include all three totals, 1 for Job dates, 2, subjobs dates, 3 cal of days for a requested period.
Your advice might helps me a lot! I'm looking for the answer for days. I would like to add 35 days to every date field in a table. I The table structure, and content is dynamically changing. Is it possible?
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.
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:
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 Tomas

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:
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.
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 am looking for a formula to calculate the number of weekdays/business days between two dates in power pivot.I do the same in SQl using the following query
DATEDIFF(dd, Date1, GETDATE()) - (DATEDIFF(wk, Date1, GETDATE()) * 2) - CASE WHEN DATEPART(dw, Date1) = 1 THEN 1 ELSE 0 END + CASE WHEN DATEPART(dw, GETDATE()) = 1 THEN 1 ELSE 0 END END
Hi, I have julian date in the format of 2003182 and I need to convert into our regular calendar date. Anybody have any SQL statement for this. Thanks, Ravi
I am trying to select data from table that have YYMM as table names, they are formatted table1410,table1411, table1412. I am trying to format it like this
declare @tablename60 varchar(50) = 'table' + SUBSTRING(CAST(DATEPART(YY,dateadd(yy, -1, getdate())) as varchar(4)),3,4) + SUBSTRING(CAST(DATEPART(MM,dateadd(mm, -1, getdate())) as varchar(2)),1,2)
But this is hard coding the YYMM, and I would like to have it pull 30,60,90 days fromthe first of the current month. I am having a bit of trouble formatting, how to accomplish this.
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()))
hi all i try to get data from sql as select * from datetable where @d between firstdate and lastdate i add parameter @d and the type is datetime when i excute the quiry
