Selecting A Series Of Dates
Jun 5, 2007
Hello Forum,
I am have posted questions regarding selecting a series of dates and am still having trouble doing so. I have been using vwd to build a website, and now would like to retrieve data from access and display a weeks worth of information at one time from selecting a column of information from the data base. I have used this section of code to do the required function. 'SELECT OrderId, CustomerId, Price FROM Orders WHERE OrderedDate BETWEEN DATEADD(d, -7, GETDATE()) AND GETDATE(), I have replaced these variables with my own, and keep getting an error message 'Undefined function 'GETDATE' in expression', I have tried many different functions to get it to work. Any ideas?
Thanks Forum,
Tim
p.s. thank you todd for replying to my first question!

if
(datalength
(cast_varchar
([Costpoint].[Profit_Calc_Consolidation].[PD])
) = 1)
then
(0 ||
cast_varchar
([Costpoint].[Profit_Calc_Consolidation].[PD]))
else
(cast_varchar
([Costpoint].[Profit_Calc_Consolidation].[PD]))
Goal:
To be able to tell the Period number ([PD]) to change from an integer to a var_char so that it can be concatenated with the Fiscal Year. I.e. Fiscal Year || Period number to produce the following results.
2006 01
2006 02
2006 03
Etc……
Status of Problem:
The issue is that I can only get it done to the point to where the Fiscal Year || Period number yields the following results:
20061
200610
200611
200612
20062
Etc….
This is as issue since I am trying to get all the information from the past to a certain year and period. Using a filter that says
Fiscal Year + Period Number <= ?Prompt_Fiscal_Year? + ?Prompt_Period_Number?
So if I enter Year: 2007 Period 3
I should get:
2006 01
2006 02
2006 03
Etc…….
2006 11
2006 12
2007 01
2007 02
2007 03
Can you please let me know if my thinking is off or if my SQL is wrong, Thank you for your assistance in this matter.

Hi guys,
I am having a problem in outputting the last two dates that a bill has been sent out.
Background:
A customers recieves a bill 4 times a year. The dates for issuing these bills are not fixed and I dont know the date that bills are usually sent out.
The database that I am using stores all of the dates that a bill would have been sent out.
Issue:
A customer recently requested to see the dates of last 2 bills along with their value.
I know that you can view a customer last date by using the following statement.
Select max(issuedate)LastBill
from statements
but i don't know how i could output the last 2 bills that were issued
Any ideas....??

I have two tables a stock table and a price table and I want to select the correct price for the Stock Date.
Problem is sometimes there is a promotion date in the price table between the live dates so the rows double up. Below is my sql but I get over 17,000 rows when it should be about 16,964.
I will post up the table and data.
SELECT a.[Company]
,a.[ProductID]
,a.[ColourSize]
,a.[StockDate]
,a.[Quantity]
,b.[Ticket Price]
FROM[Stock_Ledger] a
LEFT OUTER JOIN [Product_Prices] b
ON a.[Company] = b.[Company]
AND a.[ProductID] = b.[ProductID]
AND a.[ColourSize] = b.[ColourSize]
AND a.[StockDate] BETWEEN b.[StartDate] AND b.[EndDate]
ORDER BY a.[StockDate],a.[ProductID],a.[ColourSize]

For some reason this is just not "clicking" with me and the longer I stare at it the more I overcomplicate things and then I just confuse myself further...
Provided this relation showing where "pkey" and "skey" met on "ServiceDate":
Code:
skey pkey ServiceDate
--------------------------------------
123 1 11/12/2005
124 1 10/12/2005 *
123 2 10/02/2005
124 2 10/12/2005
124 2 11/12/2005
123 2 11/02/2005
I need to select out a list of distinct pkeys and skeys only when there was no meeting between the two in November 2005. In other words, this query would produce only one record - the starred record - when run against this sample table. This is because even though, for example, skey 124 / pkey 2 has an entry outside the desired range, it also has one inside the desired range. The same goes for the record outside our range for 123 and 2 - it also has a record inside our range.
At this point, I've come to the conclusion that I can first select all the distinct pkeys and skeys where the servicedate is not in 11/2005 then join it to a selection of distinct pkeys and skeys where the servicedate IS in the desired date range. Does that seem like the most straightforward way through this?
I don't get the impression that this is that complicated a problem, but it's one of those deals where I goofed up somewhere along the line, and now I think I'm really overthinking the problem, so I'd be much obliged if someone could give me a hearty slap to clear the ol' noggin.

Hi, I was wondering if anyone can help me write a SELECT statement to return all records (rows) based on whether they fall within two dates. For example, consider this table:
Code Snippet
--DROP TABLE #Records
CREATE TABLE #Records
(RecordID INT PRIMARY KEY NOT NULL,
StartDate DATETIME,
EndDate DATETIME)
INSERT INTO #Records
VALUES
(1, '2008-05-01', '2008-05-12')
INSERT INTO #Records
VALUES
(2, '2008-05-08', '2008-05-12')
INSERT INTO #Records
VALUES
(3, '2008-05-19', '2008-05-22')
INSERT INTO #Records
VALUES
(4, '2008-05-22', '2008-05-23')
INSERT INTO #Records
VALUES
(5, '2008-05-26', '2008-06-01')
INSERT INTO #Records
VALUES
(6, '2008-05-28', '2008-06-01')
SELECT * FROM #Records
I want to return the RecordID for any row which span this week. I've tried the simple approach of using WHERE GETDATE() BETWEEN StartDate AND EndDate but this doesn't produce the desired results. For example, RecordID 4 spans this current week but is not returned (obviously) with this approach.
The idea is to show which events (rows) are coming up this week and next week. Eventually the data will be used to populate an SSRS report.
Hope that makes sense, can anyone help?
Thanks
Matt

Hi,
I currently think Im going mad!!
I have a large table (2+Million records, 2000+ new per day). If I want to count the records in one month, I could do :-
Select Count(*) from Table1 where Added_Date between '1999-12-01'
and '1999-12-31'
or
Select Count(*) from Table1 where Added_Date >= '1999-12-01' and
Added_Date <= '1999-12-31'
For these two above, I get the same result.
HOWEVER!!
If I then do:-
Select Count(*) from Table1 where Added_Date between '1999-12-01 00:00:00'
and '1999-12-31 23:59:59'
or use the >= and <= operators, the result is larger.
If I then do :-
Select Count(*) from Table1 where Added_Date between '1999-12-01 00:00:00.000' and '1999-12-31 23:59:59.999'
or use the >= and <= operators, the result is larger still but i believe this including more rows than there actually is?.
I can get over the problem programatically using Convert to truncate to a day, month or year however, I don't understand why the results are different.
Any Ideas as to why this is happening, A'm I being stupid!!!!!!!
(PS Added_Date has a non_clustered index which has been rebuilt twice and DBCC finds no errors)
Many thanks,
Peter Farley

Hello. I need to create a page with asp 3 and sql server 2000 that lists all the records in a table that match a date criterion, but when doing so I get an error "Error Converting datetime from character string"...
I've tried this versions of the query:
Code:
SELECT (...) CONVERT(DATETIME,PAYMENTS_RECEIVED.PYR_DATE,103), (...)
FROM RESERVES LEFT OUTER JOIN (...)
WHERE (PAYMENTS_RECEIVED.PYR_DATE BETWEEN '20/03/2006' AND '21/03/2006')
and...
Code:
SELECT (...) PAYMENTS_RECEIVED.PYR_DATE, (...)
FROM RESERVES LEFT OUTER JOIN (...)
WHERE (PAYMENTS_RECEIVED.PYR_DATE >= CONVERT(DATETIME,'20/03/2006',103)) AND (PAYMENTS_RECEIVED.PYR_DATE < CONVERT(DATETIME,'21/03/2006',103))
I also tried adding " 00:00:00 a.m." to the dates to be converted in the second piece of code. If I recall correctly, "103" is the convertion code meaning "dd/mm/yyyy". That is, I expect people to type in a date like "27/03/2006" and get the table records from that date.
Weirdest thing of all is that, when using the query builder of a sqlsource control in Visual Studio Web Developer Express 2005 this following query works just fine as I expect:
Code:
SELECT (...) PAYMENTS_RECEIVED.PYR_DATE, (...)
FROM RESERVES LEFT OUTER JOIN (...)
WHERE (PAYMENTS_RECEIVED.PYR_DATE >= CONVERT(DATETIME, '20/03/2006', 103)) AND (PAYMENTS_RECEIVED.PYR_DATE < CONVERT(DATETIME, ' 21 / 03 / 2006 ', 103))
Both the server and the DB are the same in all cases, but in the first two I run the query from a (working of other queries) vbscript asp 3 page.
I know that similar posts exist already (I've searched for this before posting), but I can't fix it, at least not with the usual answer on this one (that seems to be using the convert function as in the first piece of code). Thanks in advance!!!

I’m trying to extract a list of records that don’t appear between 2 dates. I have 4 tables:
tblCustomers
tblMachines
tblServiceOrders
tblMachinesServiced
tblCustomers contains a CustomerID that is unique to each customer.
tblMachines contains a list of all machines with a MachineID that is unique to each machine. It also contains the CustomerID number.
tblServiceOrders contains a list of each time each customer was serviced. It contains the ServiceDate, CustomerID, and ServiceOrderNo. But it does not have any information on the machines.
tblMachinesServiced contains a list of each machine that was serviced for each service order. It contains the ServiceOrderNo and the MachineID number.
What I want is to be able to extract a list of machines that were not serviced between 2 dates. What I end up getting is a list of machines that were serviced outside of the date range I provide.
For instance, say machine A was serviced in 2013 and 2015 but not in 2014. And say machine B was serviced in all 3 years. When I try to extract my list of machines not serviced in 2014 I end up with a list that contains machine A-2013, A-2015, B-2013 & B-2015. But what I need is just machine A-2014, since that machine wasn’t serviced in 2014.
I’ve tried several different queries but here is an example:
SELECT tblMachines.MachineID,ServiceMachines.ServiceDate
FROM tblMachines
LEFT JOIN
(SELECT MachineID, ServiceDate FROM tblServiceOrders, tblMachinesServiced
WHERE tblServiceOrders.ServiceOrderNo=tblMachinesServiced.ServiceOrderNo
) ServicedMachines
ON tblMachines.MachineID=ServicedMachines.MachineID
WHERE YEAR(ServiceDate) != '2014'
I understand why it returns the records that it does, but I'm not sure how to get what I want, which is a list of machines not serviced in 2014.

On my SSRS report, I use a date parameter to let the user select a date with the little calendar tool. When a date is selected, I have a small bit of coding run to convert the date to text, because when the report first fires up, the field is populated with "1/1/1900," and I need that turned into a blank character to let the report pull up all rows. So far, all well and good.If someone picks a date, then the report will filter the data on that selected date. Works fine.
But, it appears there is no way to get the calendar tool to go back to allowing ALL dates - so that all records are pulled - except by manually typing in, or selecting it with the tool, 1/1/1900.If I try to clear the field, causing it to use '' as a WHERE criteria (WHERE AdmitDate LIKE '%' + @AdmitDateTxt + '%'), it repopulates the field with the last selected date. So, I guess the question is, how does one tell the calendar tool for picking dates for a date parameter to reset back such that all records are pulled, not just those for a single date, without being required to type in, 1/1/1900? Or, is there some way of telling the date parameter to select all dates?

What I am trying to do: Obtain attendance percentages for schools for the last five days. The outcome would look like this:
DISTRICTGROUPING, SCHOOLNAME, 5 DAYS AGO PCTG, 4 DAYS AGO PCTG, 3 DAYS AGO PCTG, 2 DAYS AGO PCTG, 1 DAY AGO PCTG
I am using nested subqueries for each day as follows: (total enrollment-total absent/total enrollment)
,(
((SELECTCOUNT(*)--GET TOTAL ENROLLMENT COUNT FOR SPECIFIED DATE
[Code]....
The query works with the following exceptions:
My issues are:
1. Avoid the "division by zero" error. This can occur if a school is closed for a day or if a smaller school has no absences for a day.
2. Avoid weekend dates. I need the query to display only weekdays
3. Currently I am using "PERCENTAGE 5: as a column header whereas I need the actual date as the header.

Hi, all experts here,
Thank you very much for your kind attention.
I encountered a very strange problem again. Why the time series displayed on the chart are so strange? The Key time column I chose for my time series algorithm is cal_month(e.g 199001...), but why the date displayed on the time series chart is like :05/06/2448? (it should be like 199001..?) What is that data? And where exactly did it come from? What is the exact cause of this?
Hope it is clear for your help.
I am really confused on this and thanks a lot for your kind advices and help and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

I've got a big problem that I'm trying to figure out:
I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.
I don't need this for an individual ID select, I need it applied to every record from the table.
My address table has some columns that look like:
[AddressID] [int]
[LocationID] [int]
[Type] [nvarchar](10)
[Address] [varchar](50)
[City] [varchar](50)
[State] [char](2)
[Zip] [varchar](5)
[AddDate] [datetime]
[EditDate] [datetime]
AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table.
So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.
How can I do this efficiently with perfomance in mind???
Thank you in advance for any and all replies...

Hi,
I have setup a chart with series on right hand side.
The series is from one of the fields.
How is it possible to remove series and instead place each series name on a graph line?
Or at the very least, how can I place a text on each graph line?

I m using the Time Series Algorithm to forecast sales across regions for various products. Assume the model is built with last 3 years data with the periodicity being monthly.
Is it possible that sometimes I can make predictions based on just 1 yr or 2 yrs data for certain products alone or certain regions alone? Can this be done without having to retrain the already built model?
Also, is it possible that using the model, i can predict week-wise / month-wise / quarterly sales as well?

select
starttime=cast(v.date as char(8)), endtime=cast(a.date as char(8)),
startval=v.Value, endval=a.Value,
change=substring('- +', sign((a.Value-v.Value)+2,1)+ cast(abs(a.Value-v.Value) as varchar)
from
(select date,Value, ranking =(select count(distinct date) from Test1 T where T.Value<=S.Value)
from Test1 S) v left outer join
(select date,Value, ranking=(select count(distinct date) from Test1 T where T.Value<=S.Value)
from Test1 S) a
on( a.ranking=v.ranking+1)
I got the following error message:
Server: Msg 174, Level 15, State 1, Line 4
The sign function requires 1 arguments.
Server: Msg 170, Level 15, State 1, Line 7
Line 7: Incorrect syntax near 'v'.
Server: Msg 170, Level 15, State 1, Line 9
Line 9: Incorrect syntax near 'a'.
Could someone please help with this? Thank you in advance!

I have a large number of relatively simple sql queries that each perform tests on different tables returning different columns and rows for each test.
I would like to be able to run all of these at once and get the output in a usable format.
Would it be possible to run a single query or store procedure which could perform each test then output the results from each test to a new sheet in excel?
Could it output the results of each test to individual csvs?

if
(datalength
(cast_varchar
([Costpoint].[Profit_Calc_Consolidation].[PD])
) = 1)
then
(0 ||
cast_varchar
([Costpoint].[Profit_Calc_Consolidation].[PD]))
else
(cast_varchar
([Costpoint].[Profit_Calc_Consolidation].[PD]))
Goal:
To be able to tell the Period number ([PD]) to change from an integer to a var_char so that it can be concatenated with the Fiscal Year. I.e. Fiscal Year || Period number to produce the following results.
2006 01
2006 02
2006 03
Etc……
Status of Problem:
The issue is that I can only get it done to the point to where the Fiscal Year || Period number yields the following results:
20061
200610
200611
200612
20062
Etc….
This is as issue since I am trying to get all the information from the past to a certain year and period. Using a filter that says
Fiscal Year + Period Number <= ?Prompt_Fiscal_Year? + ?Prompt_Period_Number?
So if I enter Year: 2007 Period 3
I should get:
2006 01
2006 02
2006 03
Etc…….
2006 11
2006 12
2007 01
2007 02
2007 03
Can you please let me know if my thinking is off or if my SQL is wrong, Thank you for your assistance in this matter.

I am trying to write a stored proc the calculates a moving average overthree periods. In the following example, I need to stratify the data bypersonID and RecordID in the #Temp table, but I am not sure how to doit. Right now I am restricting the data I use to build my time series bypersonID and I get the results I want *by PersonID*. If I can figure outhow stratify by personID so I don't have to use this restriction, I'msure I can extend it to the RecordID.Create Table #Temp(tmpID int identity,DetailID int,RecordID int,AdminDate Datetime,AdminTime datetime,Status tinyint,--decimal(9,2),Location varchar(100),PersonID char(9),PatientName varchar(100),DOB Datetime,Drug varchar(100),Sort varchar(10))--populate with data by personIDinsert into#Temp(DetailID,RecordID,AdminDate,AdminTime,Status ,Location,PersonID,PatientName,DOB,Drug,Sort)Select MD.PatMedOrderDetailID, MD.PatMedOrderID, M.Date as AdminDate,Case M.Time When 'A' then '8:00:00 AM' When 'N' then '12:00:00 AM' When'P' then '4:00:00 AM'When 'H' then '8:00:00 PM' else M.Time End as Admintime,100*M.Status, P.Location,P.PersonID, P.Name as PatientName, P.DOB,D.GenericName + ' (' + D.TradeName + ') ' +D.Strength,Left(P.Location,3)From PatMedOrderDetail MD Inner Join PatMedOrder MO on MD.PatMedOrderID= MO.PatMedOrderIDinner Join PatMedPass M on MD.PatMedOrderDetailID =M.PatMedOrderDetailIDinner join Patient P on M.PersonID = P.PersonIDinner join Drugs D on MO.DrugID = D.DrugIDWhere P.PersonID = '000126230'Order by P.PersonID,MD.patMedorderID, M.Date, M.TimeSelect * from #Temp -- to view entire set--returns relevant rowsSelect Derived.RefusalRate,T.* from #Temp T inner join(select t1.tmpID, avg(t2.Status) as RefusalRatefrom #Temp t1 cross join #Temp t2WHERE t1.tmpID>=3 AND t1.tmpID BETWEEN t2.tmpID AND t2.tmpID+2group by T1.tmpIDhaving avg(t2.Status)< 100) as Derived on T.tmpID = Derived.tmpIDDrop Table #Temp*** Sent via Developersdex http://www.developersdex.com ***

Hello,
I am new to SQL Server and learning lots very quickly! I am experienced at building databases in Access and using VBA in Access and Excel.
I have a time series of 1440 records that may have some gaps in it. I need to check the time series for gaps and then fill these or reject the time series.
The criteria for accepting and rejecting is a user defined number of time steps from 1 to 10. For example, if the user sets the maximum gap as 5 time steps and a gap has 5 or less then I simply want to lineraly interpolate betwen the two timesteps bounding the gap. If the gap is 6 time steps then I will reject the timeseries.
I have searched the BOL and MSDN for SQL Server and think there must be a solution using the PredictTimeSeries in DMX, but not quite sure if I can do this. I may be better off simply passing through the time series as a recordset and processing as I would have done in Access...(I am reluctant to do this as I have of the order 100 * 5 * 365 time series and growng by 100 each day and fear it will take quite some time...)
Can anyone help me by pointing me in the right direction please?
Unless there is a way of using PredictTimeSeries on its own, I think the solution is:
Identify if a record is the a valid one or part of a gap (ie missing values).
Identify the longest gap and reject or process data on this value.
Identify if a record preceedes or succeeds a gap.
For each gap fill it using a linear interpolation.
Thanks,
Alan.
