SQL Help - How To Figure Out Consecutive Workdays With Holidays
Jul 18, 2006
Hi everyone,
I'm hoping someone can help me with some sql statements. I have a temp table that contains 30 dates that a student has missed in the last year. I also have a holiday table of when training was not available. I want to find out if there are 6 consecutive days missed excluding weekends and holidays (from the holiday table). I know this is some nasty looping statement but I can't get my brain around it.
I would like do this in a stored proc but I could use C# if necessary.
Thanks in advance, Jessica

I use the NETWORKDAYS(start_date, end_date,holidays) function in Excel and Access regularly. I'm trying to find a similar function in TSQL to use on Server2005. NetWorkDays allows me to calculate the difference between my ticket open and close dates while excluding weekends and holidays, (we are nice to our staff and let them off).
I'm trying to find an easy way to do this in TSQL without writing a large amount of code.
I will greatly appreciate any help.

Hello,
I use OPENROWSET to read values from Excel and store them in a SQL Server table. In the Excel file I have a row having format 'Number' with two decimal places.
Example: 1225000.00
When I select this value using SSMS I get the correct value:
1225000
Strange enough, I cannot see the decimals anymore. However, when I now store this value into my table and then select it from there I get: (the datatype in the table is VARCHAR(max))
1.225e+006
I would not care if I could convert this back to a numeric datatype but this seems not to work: CAST('1.225e+006' as INT) throws an exception. Obviously OPENROWSET sends the data strictly as a character string. Storing this into varchar(max) works for small figures but it starts to use exp values for big figures.
Does anybody has an idea how to bring huge Excel based figures safely into a MS SQL Table ?
Thanks: Peter

Hello,
I have a query that returns a daily revenue figure. The query is as follows:
SELECT top 1000
ds.AcctCode,
ds.TxnDate,
SUM(isnull(ds.FuelFee,0)) + SUM(isnull(ds.CashFee,0)) + SUM(isnull(ds.ScFee,0)) AS TotalDailyRevenue,
--"MTD" = ?,
--"YDT" = ?,
ps.TC,
CASE
WHEN ps.Proj = 100 THEN 'New Account'
WHEN ps.Proj = 200 THEN 'Current Account'
END AS ProjStatus,
ps.FSR,
ps.SubmitRep1
FROM
TxnRptg.dbo.tbl_DailySummary ds
INNER JOIN SalesData.dbo.tbl_CYProcessedSales ps
ON ds.AcctCode = ps.Acct
WHERE
MONTH(ds.TxnDate) = 1
AND
Proj IN (100,200)
AND TC = 'HV'
GROUP BY
ds.AcctCode, ds.TxnDate, ps.TC, ps.Proj, ps.FSR, ps.SubmitRep1
ORDER BY
ds.AcctCode, ds.TxnDate
--*********************************
TxnDate represents a single day of the month. How can I include MTD so that the dates for the revenue total are from DATEADD(mm, DATEDIFF(mm,0,getdate()), 0) (beginning of current month) to TxnDate, and YTD so that the revenue totals are from DATEADD(yy, DATEDIFF(yy,0,getdate()), 0) (beginning of the current year) to TxnDate?
Thank you for your help!

Hi,
I have a table with 2 columns, a datetime column (date) and a bit column (workday)
This is a production calender. It's filled with all dates till 2020/12/31
I need a query to find the date of the n-th workday given a specific start date.
Using Sql Server 2000.
For example
Date Workday
--------------------
2007/11/01 0
2007/11/02 0
2007/11/03 1
2007/11/04 1
2007/11/05 0
2007/11/06 1
2007/11/07 1
Given the date 2007/11/03, the 2nd workday would be 2007/11/06
Thank's
Perry

This is one way you can add a number of workdays to a specific date and return a workday (monday-friday).CREATE FUNCTION [dbo].[fnAddWorkdays]
(
@StartDate DATETIME,
@DaysToAdd INT
)
RETURNS DATETIME
AS
BEGIN
RETURN@StartDate
+ CASE(@@DATEFIRST + (DATEPART(WEEKDAY, @StartDate) - 2)) % 7 WHEN 5 THEN 2 WHEN 6 THEN 1 ELSE 0 END
+ @DaysToAdd / 5 * 7
+ @DaysToAdd % 5
+ CASE WHEN (@@DATEFIRST + (DATEPART(WEEKDAY, @StartDate + CASE (@@DATEFIRST + (DATEPART(WEEKDAY, @StartDate) - 2)) % 7 WHEN 5 THEN 2 WHEN 6 THEN 1 ELSE 0 END) - 2)) % 7 + @DaysToAdd % 5 > 4
THEN 2
ELSE 0
END
END

}
}
I've tried a select query that uses getdate and returns me to the manually arranged holidays in the Holidays table, but I've failed. I wish to do that, this query arranges holidays and adds +1 day on that holiday, if this one day added day is a holiday again, than adds one day again. How can I write this code? Thanks.

Hi,
I'm working on a helpdesk project and I require the calculation of the holidays.
I need to get the time difference of the assigned date and the solved date of the helpdesk tickets considering the week-end holidays and statutory holidays. Is there any possible way to do this. I need something similar to the NetworkDays function in excel.
Thanks.

Hello,
First things first - I have a table which holds employee information (tbl_EmployeeDetails), and another table which holds information about the holidays they have booked (tbl_Holidays).
If an employee books 5 days off, 5 rows will appear in the tbl_Holidays table, each line showing 1 under the day field and 7 under the hours field.
I'm trying to produce a function which will do the following :
1) Pass in the employee number
2) Establish whether the employee works full time or part time by looking up to tbl_employeedetails, and checking the fulltime flag
3) If full time, look up to tbl_Holidays and count number of days
4) If part time, look up to tbl_Holidays and count number of hours
5) After this, return the number of holidays booked
My code is as follows :
=============
CREATE FUNCTION [dbo].[fn_Get_Booked_Holidays_Current_Year] ( @EmpNo int )
RETURNS Float
AS
BEGIN
-- Declare fields
DECLARE @FullTime int
-- Determine if Part Time or Full Time
SET @FullTime = SELECT FullTime FROM tbl_EmployeeDetails
IF @FullTime = 1
SELECT COUNT(NumberOfDays) AS TotalHolidays, EmployeeNumber AS EERef
FROM dbo.tbl_Holidays
GROUP BY EmployeeNumber
HAVING (EmployeeNumber = @EmpNo)
IF @FullTime = 0
SELECT COUNT(NumberOfDays) AS TotalHolidays, EmployeeNumber AS EERef
FROM dbo.tbl_Holidays
GROUP BY EmployeeNumber
HAVING (EmployeeNumber = @EmpNo)
END
==========
Can someone please let me know where I'm going wrong, or what I need to do to get this function done?
Thanks,
J

Is there an equivalent function in SQL to the'NETWORKDAYS(start_date,end_date,holidays)' function in Excel ?NetworkDays in Excel returns the number of whole working days betweenstart_date and end_date. Working days exclude weekends and any datesidentified in holidays. This part isn't vital but would be nice tohave. The weekend stuff is more important.I realise this will most likely need to be some method I write myself(possibly based on the name of the day - Mon-Fri), but any pointerswould be appreciated if anyone has done this before.ThanksRyan

The below code works fine to measure the difference in days between two dates.
However, there is an additional business requirement to subtract week-ends, and holidays, from the equation.
Any ideas on how to accomplish this task, and leverage the below, existing code? Thanks in advance!
(SELECT ABS((TO_DATE(TO_CHAR(" & ToFieldDate & "),'yyyymmdd') - TO_DATE(TO_CHAR(" & FromFieldDate & "),'yyyymmdd'))) FROM DUAL) AS Measurement "

Also includes ISOWeek & Weekends
Dont know whether this is of any use to anyone or it has been done before but there are a lot of posts on here regarding date calculation issues & usually the most straight forward answer is to compare against a table of dates.

Hello,
I have a stored procedure that inserts 5 rows into a table. The execution of the SP is inside a transaction like in the code below:
Code Block
SqlConnection conn = new SqlConnection(ConnectioString);
conn.Open();
SqlTransaction trans = conn.BeginTransaction();
try
{
// execute stored procedure... insert 5 rows
trans.Commit();
}
catch (Exception ex)
{
trans.Rollback();
}
finally
{
conn.Close();
}
Suppose that N users are executing the code, one independent of the other, in the same time and they both commit the transaction at the same time.
Can I suppose that the rows inserted in the table by one user will be consecutive?
Thanks!

Hi,I'm
trying to insert records from one table into another table. The
destination table has a ROWID field which cannot be an identity key,
but needs to 'act like' an identity key and have its value populated
with (Max(ROWID) + 1) for each row added to the table.To my
thinking, simply using (Max(ROWID) + 1) in my SELECT statement will not
work as it will only be evaluated once so if I am adding 1000 records
and Max(ROWID) is 1234, all 1000 entries will end up having a ROWID of
1235.Is there a way to accomplish this?Thanks

I have create a sample db idenifying donor, giving year and total pledges with multiple donor records existing for multiple years having donated.
CREATE TABLE mygifts06 (Donor_id varchar (10), Gift_yr nvarchar (4), Tot_pledges numeric (16,2))
INSERT INTO mygifts06 (Id,Gift_yr,Pledges)
SELECT 155758,2005,15.00 UNION ALL

SELECT 155757,2003,65.00 UNION ALL
SELECT 155759,2005,400.00
For the above dataset, I am trying to create the following output

--------- -------------- -------------- --------------
155755000
155757000
155758110
155759100
Do I need to use a cursor for this task? I lack experienced in using cursors is there an alternative method someone could suggest?

I am using the following query (which works fine):
select
min(timex) as start_date
,end_date
,entityid
,entityname
,locationid
[code]....
However I would like to not use the delta (it takes effort to calculate and populate it); instead I am wondering if there is any way to calculate it as part / whilst running the query.
Problem 2
I have the following table which shows the location of different people at 1 hour intervals

I'm trying extract a count of consecutive numbers, or "unbroken" years inthis case, at any particular given time.For example (simplified):CREATE TABLE #Customers(CustNo INT,YearNo INT,IsCust CHAR(1))INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2006, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2005, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2004, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2003, 'N')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2002, 'N')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2001, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2000, 'Y')SELECT * FROM #CustomersCustNo YearNo IsCust----------- ----------- ------999 2006 Y999 2005 Y999 2004 Y999 2003 N999 2002 N999 2001 Y999 2000 YIn 2006 CustNo 999 would have been active for 3 years, 2004 for 1, 2001 for2, etc. Ideally I'd feed it a single year to lookupI'm resisting the urge to create cursor here -- anyone have any hints?....Chris.

Hello,Can someone please help me with a query?The table looks like this:BookedRooms===========CustomerID RoomID BookDateID1 1 200507011 1 200507021 1 200507031 1 200507091 1 200507101 1 200507111 1 20050712Desired result:CUSTOMER STAYS==============CustomerID RoomID ArriveDateID DepartDateID1 1 20050701 200507031 1 20050709 20050712Basically, this is for a hotel reservation system. Charges varynightly, and customer changes (shortening/extending stay, changingrooms, etc) happen quite often. Therefore, the entire stay is bookedas a series of nights.The length of the stay is never known, so it needs to be derived viathe Arrive and Depart Dates, based on the entries in the table.Notice, customers often stay in the same room, but with gaps between,so a simple MIN and MAX doesn't work. The output needs to showconsecutive nights grouped together, only.I've researched this quite a bit, but I just can't seem to make itwork.Any help would greatly be appreciated.Thanks!

I'm in desperate need of help. I'm setting up an intranet portal using DNN. I added an event calendar module, but whenever I try to add events to it, the system rejects it with a nasty Sql exception saying the conversion from char to datetime produced an out of bounds result.
The string the table uses to convert to datetime is (I have not modified it, the module is exactly as it came when i downloaded)
(convert(varchar,getdate(),101))
The whole stack trace for the error is:
Stack Trace:
[SqlException: La conversión del tipo de datos char a datetime produjo un valor datetime fuera de intervalo.]
System.Data.SqlClient.SqlCommand.ExecuteReader(Com mandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream) +642
System.Data.SqlClient.SqlCommand.ExecuteReader() +11
DotNetNuke.AVCalendarDB.Save() +1067
DotNetNuke.AVCalendarEdit.updateButton_Click(Objec t sender, EventArgs e) +3367
System.Web.UI.WebControls.LinkButton.OnClick(Event Args e) +108
System.Web.UI.WebControls.LinkButton.System.Web.UI .IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +57
System.Web.UI.Page.RaisePostBackEvent(IPostBackEve ntHandler sourceControl, String eventArgument) +18
System.Web.UI.Page.RaisePostBackEvent(NameValueCol lection postData) +138
System.Web.UI.Page.ProcessRequestMain() +1263
At first I thought it could be a language issue (DNN and the module are in english and my system runs XP Pro in Spanish) but I discarded it since it didn't work when I installed XP Pro in english
Any ideas?? I would really appreciate your help
Best regards from Chile

Hi, I am somewhat new to t-sql and what I do know is from trial & error and help from this forum. What I need to do is add a column of counts for id numbers that are not unique.
This is my code:
ALTER procedure [dbo].[rptMgmtRpt]
@RptMonthBegin datetime,
@RptMonthEnd datetime
as
SELECT Summons.ID, Convert(varchar, Venire.VenireDateTime,101)as VenireDateTime, Venire.VenireStatusID, Summons.SummonsStatusID, Summons.ExcusalCodeID,
Venire.ID AS VenireID, { fn WEEK(Venire.VenireDateTime) } AS wkNum, { fn DAYOFWEEK(Venire.VenireDateTime) } AS wkDay, Venire.JuryTypeID,
Venire.VenireLocationID, summons.compensationTypeID
,{fn IFNULL(AccountingTransactionRequest.PaymentAmount,0)} AS payAmt
,Convert(varchar,AccountingTransactionRequest.ServiceDate,101) as AcctServDate
,{fn count(summons.id)}
FROM Venire INNER JOIN
Summons ON Venire.ID = Summons.VenireID
LEFT outer JOIN
AccountingTransactionRequest ON Summons.ID = AccountingTransactionRequest.SummonsID
Where Venire.VenireLocationID <> 16 and (VenireDateTime BETWEEN @RptMonthBegin AND @RptMonthEnd)
ORDER BY wknum, wkday , Summons.ID
This is a sample of what I get for results:
640404 11/5/2007 128 144 2866 45 2 8 0 11/5/2007
640888 11/5/2007 128 32 2866 45 2 8 0 11/5/2007
640979 11/5/2007 32 2 2866 45 2 112 15 11/5/2007
640979 11/5/2007 32 2 2866 45 2 112 15 11/6/2007
640979 11/5/2007 32 2 2866 45 2 112 15 11/7/2007
641533 11/5/2007 128 32 2866 45 2 8 0 11/5/2007
641762 11/5/2007 128 144 2866 45 2 8 0 11/5/2007
641851 11/5/2007 1024 2 2866 45 2 8 0 11/5/2007
What I need are results that look like this:
640404 11/5/2007 128 144 2866 45 2 8 0 11/5/2007 1
640888 11/5/2007 128 32 2866 45 2 8 0 11/5/2007 1
640979 11/5/2007 32 2 2866 45 2 112 15 11/5/2007 1
640979 11/5/2007 32 2 2866 45 2 112 15 11/6/2007 2
640979 11/5/2007 32 2 2866 45 2 112 15 11/7/2007 3
641533 11/5/2007 128 32 2866 45 2 8 0 11/5/2007 1
641762 11/5/2007 128 144 2866 45 2 8 0 11/5/2007 1
641851 11/5/2007 1024 2 2866 45 2 8 0 11/5/2007 1
In the first column, 640979 appears three times.
How do I get that count in the last column of my results ?
Thanks so much for your help!!!

SQL Server 2008.
From individual event logs I have generated a table where arrivals and departures at a location are registered per device. As there are multiple registration points, there might be multiple consecutive registrations per location.
If this is the case I need to filter those out and have one registration per location and in the result I need to get the earliest arrival and the latest departure of these consecutive rows.
Part of the table:
logIDdeviceIDArrivedDepartedLocationIDGrp1Grp2Grp
3485441082013-02-07 17:51:05.0002013-02-07 17:51:15.0005110
3492041082013-02-07 17:51:15.0002013-02-07 17:51:26.0005220
3500241082013-02-07 17:51:27.0002013-02-07 17:51:37.0003312
3508941082013-02-07 17:51:41.0002013-02-07 17:51:54.0004413
[Code] ....
So as long the field LocationID is the same in the next row, it needs to be grouped.
I have added the rows Grp1, Grp2, Grp in an attempt to get an unique grouping number with the following script in the select statement:
,ROW_NUMBER() OVER(PARTITION BY DeviceID
ORDER BY logID) AS Grp1
,ROW_NUMBER() OVER(PARTITION BY DeviceID, LocationID
ORDER BY logID) AS Grp2
,ROW_NUMBER() OVER(PARTITION BY DeviceID
ORDER BY logID)
-
ROW_NUMBER() OVER(PARTITION BY DeviceID, LocationID
ORDER BY logID) AS Grp
By subtracting Grp2 from Grp1 (Grp = Grp1 - Grp2) I hoped to get an unique group number for each set of equal consecutive locations, however the Grp2 column does not restart from 1 each time the LocationID changes: Grp2 in line 7 should have been 1 again, but it is 2 because this is the second row with LocationID = 3 in the list.

Problem 1: I have the following table which shows the location of a person at 1 hour intervals
IdEntityIDEntityNameLocationIDTimexdelta
11MickeyClub house03001
21MickeyClub house04001
31MickeyPark05002
41MickeyMinnies Boutique06003
51MickeyMinnies Boutique07003
61MickeyClub house08004
71MickeyClub house09004
81MickeyPark10005
91MickeyClub house11006
The delta increments by +1 every time the location changes.
I would like to return an aggregate grouped by delta as per example below.
EntityNameLocationIDStartTimeEndTime
MickeyClub house03000500
MickeyPark05000600
MickeyMinnies Boutique06000800
MickeyClub house08001000
MickeyPark10001100
MickeyClub house11001200
I am using the following query (which works fine):
select
min(timex) as start_date
,end_date
,entityid
,entityname
,locationid
[code]....
However I would like to not use the delta (it takes effort to calculate and populate it); instead I am wondering if there is any way to calculate it as part / whilst running the query.
Problem 2:I have the following table which shows the location of different people at 1 hour intervals
IdEntityIDEntityNameLocationIDTimexDelta
11MickeyClub house09001
21MickeyClub house10001
31MickeyPark11002
42DonaldClub house09001
52DonaldPark10002
62DonaldPark11002
73GoofyPark09001
83GoofyClub house10002
93GoofyPark11003
I would like to return an aggregate grouped by person and location.
For example
EntityIDEntityNameLocationIDStartTimeEndTime
1MickeyClub house09001100
1MickeyPark11001200
2DonaldClub house09001000
2DonaldPark10001200
3GoofyPark09001000
3GoofyClub house10001100
3GoofyPark11001200
What modifications do I need to the above query (Problem 1)?

Hello,
I have a table with 3 columns: Item# | Date | ItemAmount.
Everyday there is a number of transactions entered. An Item# can only be entered once par day (if it has occurred that day).
What I want to do is to :
retrieve the number of total days where an Item has been entered for more than 2 consecutive days (for the month).
Example: if item I022 has been entered Monday and wed, then ignore, but if it's been entered Mon, Tues then return 2, if Mon, Tues, Wed then return 3 because the days are consecutive.
Does anyone have an idea.
thanks in advance,
