SQL Server 2008 :: Rank Function Taking Care Of Gap Between Days
May 24, 2015
Working on sqlserver 2008 R2
CREATE TABLE OrderRanking
(
OrderID INT IDENTITY(1,1) NOT NULL,
CustomerID INT,
OrderDate date
)
INSERT OrderRanking (CustomerID, OrderDate)
[Code] ...
Looks fine but what I need is DRP with this:
CustomerID OrderDate 'DRP taking care of the gap in the days'
1 '01-01-2015' 1
1 '01-01-2015' 1
2 '02-01-2015' 1
2 '02-01-2015' 1
2 '05-01-2015' 4
2 '05-01-2015' 4

I want to be able to track my top 100 items sold in the last 60 days. Each night I want to calculate it then compare it with the numbers from the previous night. Then show both ranks. My problem is assigning them ranks. Bascily I have a view that shows the top 200 sorted correctly. I am thinking creating a DTS to make a new table with adding transformations. But I am not sure how to code the Visial Basic. Below is what I thought it would be, but it doesn't work. Get a generic error. Any ideas?dim ranknumranknum = 0Function Main() ranknum += 1 DTSDestination("Rank") = ranknum DTSDestination("ItemNumber") = DTSSource("ItemNumber") DTSDestination("QtySold") = DTSSource("QtySold") Main = DTSTransformStat_OKEnd Function

We have accounts that pay for a particular "premium" service. It's entirely possible an account paid for this service for three consecutive months in 2013, then stopped paying, then started paying again. Why I'm trying to establish is, for the FIRST period of time the accout paid for this service, for how many consecutive months did they pay? Here is my test data:
if object_id('tempdb..#SampleData') is not null
drop table #SampleData
go
if object_id('tempdb..#DateAnalysis') is not null
drop table #DateAnalysis
go
-- Create temp tables for sample data
create table #SampleData
(AccountID int,
RandomDate datetime)
create table #DateAnalysis
(RowID int identity(1,1),
AccountID int,
RandomDate datetime,
NextDate datetime,
LeadInMonths int)
-- Insert some sample data
insert into #SampleData values
(1, '1/1/13'), (1, '2/1/13'), (1, '3/1/13'), (1, '6/1/13'), (1, '10/1/13'), (1, '11/1/13'), (1, '12/1/13'),
(2, '1/1/13'), (2, '4/1/13'), (2, '5/1/13'), (2, '6/1/13'),
(3, '2/1/13'), (3, '3/1/13'), (3, '4/1/13'), (3, '9/1/13'), (3, '10/1/13'), (3, '11/1/13')
-- Use lead function to determine how many months are between
-- consecutive dates per account
; with DateInterval as
(select AccountID, RandomDate,
NextDate = lead (RandomDate, 1, NULL) over (partition by AccountID order by RandomDate)
from #SampleData)
insert into #DateAnalysis
select AccountID, RandomDate, NextDate,
datediff(mm, RandomDate, NextDate) as 'Lead'
from DateInterval
where NextDate is not null -- Last row will contain NULL for NextDate. Don't include these rows.
-- Show the results
select *,
'NTile' = NTILE(3) over (partition by AccountID order by RandomDate),
'RowNum' = row_number() over (partition by AccountID order by RandomDate)
from #DateAnalysis
Results (this is not getting me what I'm looking for):
RowIDAccountIDRandomDateNextDateLeadInMonthsNTileRowNum
11 2013-01-012013-02-01111
21 2013-02-012013-03-01112
31 2013-03-012013-06-01323
41 2013-06-012013-10-01424
51 2013-10-012013-11-01135
61 2013-11-012013-12-01136
72 2013-01-012013-04-01311
82 2013-04-012013-05-01122
[code]....
This is what I'm trying to achieve:
RowIDAccountIDRandomDateNextDateLeadInMonthsRankForThisLeadInMonths
11 2013-01-012013-02-0111
21 2013-02-012013-03-0111
31 2013-03-012013-06-0132
41 2013-06-012013-10-0143
51 2013-10-012013-11-0114
61 2013-11-012013-12-0114
[code]....
The problem comes with accounts like AccountID = 1. They paid consecutively to start, then skipped, then started paying consecutively again. When using window functions, I'm running into trouble attempting to partition by AccountID and LeadInMonths. It's putting all the LeadInMonths = 1 together and that will give me skewed results if I want to know the earliest and latest date within the FIRST consecutive range of dates where the account paid. I've tried NTILE but it expects an integer and there's no telling how many "tiles" would be in AccountID partition.
I've looked at the OVER clause and the new "ROWS BETWEEN" syntax and still cannot get the desired results.

Hi ,
I have a report created and within the report is columns that perform additions on the fields from the database.
I want to create a rank column to show the rank of the row compare with the rest.
Col1 Col2 Total Ranks
1 2 3 3
2 3 5 1
2 2 4 2
On the above Col 1 and 2 would come form my database, Total is calculated by the report. How can I get ranking on this total? I cannot sort by the total as the report should only showing rankings but not be ordered by the rank.
I am using SQL Server 2005 Reporting Services...anny help is much appreciated.
Thanks

I need some with selecting the number of days, in a month, between a date range. For example, my data looks like:
FileNumb | startdate | enddate
1 04/25/2015 05/02/2015
2 05/01/2015 05/10/2015
The output I am looking for would be:
FileNumb | Year | Month | Days

Our fiscal year starts on July 1st. Each month they call a period - so July is period 1, August is period 2, etc.
They are wanting a report that pulls numbers for a given period. There are parameters for them to select the fiscal year and the fiscal period, and then it calculates the numbers for that period. That part works fine.
Now they want me to do some calculations, and one of them is to divide one of the numbers by the # of days since the fiscal year. So if they choose July, it would be 31 days. If they choose August, it would be 61 days, etc. How can I set this up to calculate the number of days when they really aren't entering a start date, it's just a fiscal year and period.
Is there a way to calculate a date field that is 07/01/xxxx where xxxx is the fiscal year they chose? Also a way to calculate a date field that would be the last date of the month for the fiscal period and year they chose?
I suppose I could add 2 other parameters where they enter the start of the current fiscal year, and the last day of the period they're running it for, and use a datediff to calculate that. Just seems kind of redundant.

Hi
Due to an impending acquisition the machine names of the SQL Server 2005 boxes are changing. Trying this in the DEV environment it seems that the SQL server instance name stays the same as the old machine name (It was installed using the default of the machine name) -- but the clients now won't connect with the old machine name, or the new machine name -- it only works with the IP address.
I'm guessing there's a sp_change_instance_machine_name or something along those lines but can't seem to find it in BOL. Can someone point me in the right direction?
Thanks in Advance

Hi,
Does anyone has the DAYS360 excel formula in a function in sqlserver ?? I did this one
FUNCTION dbo.fnDays360_EXCEL
(
@startDate DateTime,
@endDate DateTime
)
RETURNS int
AS
BEGIN
RETURN (
(CASE
WHEN Day(@endDate)=31 THEN 30
ELSE Day(@endDate)
END) -
(CASE
WHEN Day(@startDate)=31 THEN 30
ELSE Day(@startDate)
END)
+ ((DatePart(m, @endDate) + (DatePart(yyyy, @endDate) * 12))
-(DatePart(m, @startDate) + (DatePart(yyyy, @startDate) * 12))) * 30)
END
But there is a bug, if the end date is bigger then february, february must have 30 days and not 28 or 29...
Does anyone has the solution ?
Thanks

Recently I have come across a requirement where i need to design a table.
There are some columns in table like below with DECIMAL Datatype:
BldgLength
BldgHeight
BldgWeight
Based on my knowledge, i know that values before Floating-Point will not be more than 4 digits.
Now as per MSDN,
Precision => 1 - 9
Storage bytes => 5
so i can create column as:
BldgLengthDECIMAL(6,2) DEFAULT 0
OR
BldgLengthDECIMAL(9,2) DEFAULT 0
Now while reading some articles, i came to know that when we do some kind of operation like SUM Or Avg, on above column then result might be larger than current data type.
So some folks suggested me that i should keep some extra space/digits considering above MATH functions, to avoid an Arithmetic Over Flow error.
So my question is what should be value of DataType for above column ?

I've been wrestling with some questions about databases.1. I allow my databases to grow 10% and I find that I will have tons ofexcess space according to EM database properties. I try to shrink butit doesn't. I try a full databack up and transaction backup, but theshrink still doens't help. (I understand that it may be bad form toallow the database to automaticly grow, however I wish to learn ofwhats going on here. Changing the option to prevent growth wont teachme anything) ;)2. Because of the above situation, I've found a brute force way: Createa smaller database (the original size) and use Import/Export to copyall the data and objects. However, many times this process will failwith vague errors, (when I check for details about the error, it justrestates it had an error, nothing I could sink my teeth into).Anyone have links or info that speaks to these situations, or "Do's andDont's" about database maintance?TIA

After migrating, the developer test code, and got an error: ERROR [HY010] [Microsoft][ODBC SQL Server Driver]Function sequence error...But this is a release for 2008, ours is already 2008 R2 SP1, so that hot fix should already be included since it is always cumulative.

I'm unable to reproduce the error. when they upgrade their OS and SQL EXPRESS to a more recent version the error disappears.
The error is: Incorrect syntax near '.'
the query in question resembles this:
Select column1, column2
from Table1 T
cross apply function(t.column4,t.column5) F
where column3 = 'XXXX'
I made sure that the compatibility level is greater than 90 this error is happening on SQL2005 SP2 as well as SQL2008 with SP2 (but not all clients are suffering from the same problem)
Can it be the .net framework? Although the machines had .net framework 3.52.
Can the OS be an issue? The OS' seem to be old, Windows Server 2008 SP2
I've tried to reproduce the error by setting up virtual machines with same OS and SQL but, again, can't reproduce.

I have a recursive CTE on an inline table valued function. I need to set the MAXRECURSION option on the CTE, but SQL Server is complaining with "Incorrect syntax near the keyword 'OPTION'".
It works fine on non-inline function. I couldn't find any documentation indicating this wasn't possible.
I can use the MAXRECURSION option in call to the function
SELECT * FROM MyFunction ()
OPTION ( MAXRECURSION 0 )
but that means that the user needs to know the "MyFunction" uses recursive CTE, which defeats the purpose of the abstraction.

I am trying to get the last 60 days before a month starts. I have a set that is returned from the query below :
SELECT
non empty
[Measures].[TRANSACTIONS Count] on 0,
non empty ([TRANSACTIONS].[Days].[Days],
[TRANSACTIONS].[Transaction Month].[Transaction Month]) on 1 from [cube]
I can get the cummulative count of last 60 days before month 2 by hardcoding the day of transaction of start of month like below :
WITH MEMBER
[Measures].[Cumm Account Count]
AS
(
AGGREGATE( [TRANSACTIONS].[Days].CurrentMember:NULL ,[Measures].[TRANSACTIONS Count])
)
SELECT
non empty [Measures].[Cumm Account Count] on 0,
non empty [TRANSACTIONS].[Days].&[3]:[TRANSACTIONS].[Days].&[3].lead(60) on 1 from [cube];
and for subsequent months by using the dates that the following month starts. How can I achieve the above result without having to use the day numbers, I tried to use the tail function (to get the months and star date) but it wont work because the range function accepts members only...

I have events which require certain things be done several days before the event and things be done several days after the event. I attempted to use the DATEADD function to subtract 3 days from the event date. The SQL Statement I created did just that, but, it displays 3 days back from today's date.
There are 2 tables:
CalendarCategories -- Table
CalCategoryID -- int field
CalCategoryName -- varchar field
CalendarEvents -- Table
CalCategoryID -- int Field
Title -- varchar Field
StartDate -- DateTime Field
I have to perform some tasks 3 days before the event. So, TODAY, I want to see a listing of those events which are scheduled for 3 days FROM NOW.
This is my current SQL Statement:
SELECT DATEADD(d,-3,StartDate) AS [Update Payoffs & Ins], Title AS [Closing Description] FROM CalendarEvents WHERE datepart(dd,StartDate)=datepart(dd,getdate()) AND datepart(mm,StartDate)=datepart(mm,getdate())
This SQL Statement takes TODAY'S events and gives them a date of February 20. See example of the results at http://www.joelwilliamslaw.com/DesktopDefault.aspx?tabid=141
This is what I have already done relative to my calendar listings:
Specific Event Types for the Current Month :
SELECT StartDate AS [Date and Time], CalCategoryName AS [Cls Type], Title AS [Closing Description] FROM CalendarEvents inner join CalendarCategories
on CalendarEvents.CalCategoryID = CalendarCategories.CalCategoryID
where (CalendarEvents.CalCategoryID = 1 OR CalendarEvents.CalCategoryID = 2 OR CalendarEvents.CalCategoryID = 3 OR CalendarEvents.CalCategoryID = 4 OR CalendarEvents.CalCategoryID = 20) AND (datepart(mm,StartDate)=datepart(mm,getdate()) AND datepart(yy,StartDate)=datepart(yy,getdate())) AND CalendarEvents.ModuleID = 360 ORDER BY StartDate ASC
Specific Event Types for the Current Day:
SELECT StartDate AS [Date and Time], CalCategoryName AS [Cls Type], Title AS [Closing Description] FROM CalendarEvents inner join CalendarCategories
on CalendarEvents.CalCategoryID = CalendarCategories.CalCategoryID
where (CalendarEvents.CalCategoryID = 1 OR CalendarEvents.CalCategoryID = 2 OR CalendarEvents.CalCategoryID = 3 OR CalendarEvents.CalCategoryID = 4 OR CalendarEvents.CalCategoryID = 20) AND (datepart(dd,StartDate)=datepart(dd,getdate()) AND datepart(mm,StartDate)=datepart(mm,getdate()) AND datepart(yy,StartDate)=datepart(yy,getdate())) AND CalendarEvents.ModuleID = 360 ORDER BY StartDate ASC
Your assistaince is much appreciated.
