I tried this, but I am getting 7 as a result.SELECT DATEDIFF(weekday, request_start_date, request_end_date) AS days_off, request_id
FROM request Any help would be greatly appreciated.

DateDiff - Return Months In Decimal?

Jun 24, 2004

I've been trying to create a function that returns the difference, in months, between two dates. The DateDiff function (m) returns an integer, but I really need a decimal. I could return the days instead, but it would be difficult to figure out how the number of months from this, especially when the dates span multiple years and I need to adjust for leap year. Does anyone know of a resource that might have a solution for this?

Thanks,
Rob

Using Datediff Function To Return 1st Of Month. Different Results With T-SQL And SSIS

May 15, 2007

Hi



I regularly use the T-SQL date functions to return the 1st of a particualr month.



e.g.



SELECT DATEADD(m,DATEDIFF(m,0,getdate()),0)



returns 2007-05-01 00:00:00.000



i.e the first of the current month at midnight.

However, when I try to use a similar expression as a derived column in SSIS it returns a completely different date.



DATEADD("month",DATEDIFF("month",(DT_DATE)0,GETDATE()),(DT_DATE)0)



returns 30/05/2007 00:00:00





Any ideas why and how I can obtain the first of a particualr month using SSIS derived column?

Data Warehousing :: DateDiff Function To Return Positive Value Irrespective Of Values Passed

Aug 7, 2015

I have a requirement to use DateDiff(Months,DateTime1,DateTime2) and this must return positive integer values.

Currently negative numbers are being returned because DateTime1 < DateTime2  or DateTime1 > DateTime2 .

The DateTime1 and  DateTime2  values are dynamic and either of them can be bigger than the other.

Any query solution so that always positive value is returned.

DATEADD - Add Weekdays Only

Sep 20, 2006

Hi, I have a problem with working out some dates. I have a query that has a start date field and a number of days field. I know i can create another field that could provide the return date (DATEADD function) by adding the number of days to the start date. However the problem I have is that i need to discount the weekends from the return date. For example if the start date was a wednesday and the number of days was 3 the datadd sum would give a return date of saturday when in reality it should be monday. I am not sure if i am making sense but if anyone out there has any ideas it would be more than welcome. Andrew

# Of Weekdays Between Dates Excluding Sat/Sun

May 14, 2002

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?

Calculating Work Hours For Only Weekdays

Dec 11, 2007

Hi All,

I am having some problems to calculate the basic work hours for a particular month.
Example is I chose for the month of November, I would like to calculate the number of working days (not weekends) and then multiply by 8 (assuming work hour is 8). The month also would be dynamically chosen from a list and not a fix attribute
Can this be done on reporting services?
Basically I am trying to port the same calculation from crystal report.
The crystal report code is as below:

(if DayOfWeek ({?From}) in 2 to 5 then
8
else if DayOfWeek ({?From}) = 6 then
7
else 0)
+(DateDiff ("ww",{?From} ,{?To}, crMonday)* 8) + (DateDiff ("ww",{?From} ,{?To}, crTuesday)* 8)
+ (DateDiff ("ww",{?From} ,{?To}, crWednesday)* 8) +
(DateDiff ("ww",{?From} ,{?To}, crThursday) * 8)+
(DateDiff ("ww", {?From}, {?To}, crFriday)*7 )

Thanks in advance for your help.

Regards,
Mohd Fadzli

This IS Self-join Friday, Isn't It?

Jun 11, 2004

Hi all...I'm still trying to figure out a query related to the topic I posted yesterday about the table scan...got past that...it was smoke and mirrors...

Now...I have a table that looks like (essentially) this:
BegDate (smalldatetime)
EndDate (smalldatetime)
PortfolioID (int)
WklyPerPriceChg (float)

I am trying to come up with a query that returns a table that looks like this:
BegDate, EndDate, WklyPerPriceChg for PortfolioID1, WklyPerPriceChg for PortfolioID2, WklyPerPriceChg for PortfolioID3, WklyPerPriceChg for PortfolioID4

Here is my select:SELECT TOP 100 PERCENT
T.BegDate as StartDate,
T.EndDate as EndDate,
SP.WklyPerPriceChg as Sandp,
WR.WklyPerPriceChg as WeekRvw,
NA.WklyPerPriceChg as NewAm,
T.WklyPerPriceChg as T100
FROMdbo.WeeklyPortfolioIndex T (nolock) INNER JOIN
dbo.WeeklyPortfolioIndex WR (nolock) ON T.BegDate = WR.BegDate INNER JOIN
dbo.WeeklyPortfolioIndex NA (nolock) ON T.BegDate = NA.BegDate INNER JOIN
dbo.WeeklyPortfolioIndex SP (nolock) ON T.BegDate = SP.BegDate
WHERE((T.BegDate >= @FirstBegDate) AND
(T.EndDate <= @LastEndDate)) AND
SP.PortfolioID = 2 AND
WR.PortfolioID = 67 AND
NA.PortfolioID = 11 AND
T.PortfolioID = 90
ORDER BY T.BegDate DESC

I think you can disregard the date stuff that seems to be working.

What I am finding though, is that the self-join only returns rows for dates that have ALL FOUR of the target portfolioID's. What I want is a row for any day that has AT LEAST ONE of the portfolios, and would like NULL or zero returned in the columns for any portfolioID that does NOT have a row present in the table for that date(range).

I thought I would try a FULL OUTER join rather than the inner one (which I would expect to return an output row if ALL portfolio rows were present for that day)...but that returns more of a cartesian product type thang rather than what I am looking for.

I further thought I need something like a GROUP BY T.BegDate, for example, but then it complains that my select columns are not aggregates.

I know this should be fairly easy...I'm just missing the boat by mere inches, I think...

And missing by "mere inches" is still enough to leave me all wet ;)
Thoughts?
Thanks!

Friday Fun - RunningTotalsAnyone?

Dec 15, 2006

If I put this in crystal reports I can manipulate it ok, but actually translating it to a command isn't so easy for me. I'm terrible at cursors and need some help here, pretty pretty please.

I have a table...

CREATE TABLE [dbo].[StagePayment] (
[PaymentID] [uniqueidentifier] NOT NULL ,
[JobID] [uniqueidentifier] NOT NULL ,
[Paid] [bit] NOT NULL ,
[Sequence] [smallint] NOT NULL ,
[Amount] [decimal](10, 2) NOT NULL ,
[Activity] [varchar] (30) NULL ,
[ActivityID] [uniqueidentifier] NULL ,
[DueDate] [datetime] NULL ,
[InvoiceNumber] [varchar] (50) NULL ,
[DueNext] [bit] NOT NULL
) ON [PRIMARY]
GO

Simple example of the data I need to work with...

PayIDJobIDPaidSequenceAmountDueNext

609412110.000
6B1E 18110.000
297C 25110.000
E175 30114390.000
8CF9 30124390.000
916839114400.000
59F4 39126632.000
BCAF 5411417.500
59225402417.500
8DA0 68112988.000
76C5 68129958.000
0C13 68137566.000
F3F4 68142390.000

What I need to accomplish is flagging the DueNext field if the amount due has not been paid. I cannot rely on the Paid field as it's currently user controlled. I need to compare what's due with the total already paid (stored in another table).

So for instance,
Job #68 - the total amount due would be $22902.00

If the customer has paid $15000.00 then Sequence 3, PayID 0C13, should be flagged as DueNext.

Anyone have a very simple example of a running total cursor that I can reference or a better idea of how to work with this? I appreciate any and all suggestions!
Thanks!

Get Next Friday Of Week

May 22, 2008

I want to make a function which returns the next Friday, given a day in the week. I can't find a solution which works. For example:

Input -> Output
4/22/08 -> 4/23/08
4/23/08 -> 4/23/08
4/24/08 -> 4/30/08

I can't find a solution which works. According to one website, this should do it:
DECLARE @Friday DATETIME
SET @Friday = '20000107'
SELECT DATEADD(day, ((DATEDIFF(day, @Friday, GETDATE()) / 7) * 7), @Friday)

Get Last Monday Through Sunday Data Question

Jan 12, 2007

I'm using VB.Net and SQL Server. Here's the scenario I have that I can't figure out how to accomplish:
(btw, this is all manual - I'm NOT using an ASP.Net Calendar control) I want to provide a week's worth of calendar data automatically. Let's say I have all the calendar dates and times in a table. But - I only want to show the data from the current week.
So, no matter which day the end user loads the page (Monday, Tuesday, Saturday, etc), I want to be able to find the previous Sunday (or Monday?), and then provide data from the table for events that are happening from that Monday, through the next Sunday.
Finding the last Monday (or Sunday?) is the first problem, and then getting only data between that date and the following Sunday is the second problem - how to create the code and hw to create the sql statement - -
any ideas?

Last Monday Date As Default Parameter Value

Dec 3, 2007



I have a stored procedure that grabs the Region key from the user, and the date. But i want to set up 5 reports, for day of the week. So i want to make the second parameter a defualt parameter set by me in each report. which is better then having to create 5 stored procedures with the same info just different dates.
when i try to enter the same data i have in my stored procedure to get Mondays date, i get an error.

Here is what i entered in the report parameter default expression box for the date :


=DATEADD(dd, - 6, DATEADD(dd, 1 - DATEPART(w, GETDATE()), CONVERT(varchar, GETDATE(),

101))))


but i keep getting an error that says:


The Value expression for the report parameter €˜Daily_activity_statistics_datetime€™ contains an error: [BC30451] Name 'dd' is not declared.

Build complete -- 1 errors, 0 warnings



whats wrong with it? This works fine in the stored procedure for the where clause. Please help! this would save me alot of time.
