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":
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.
When im using the below query im getting the output, but when i change the starting date to 2006 I'm not getting the data for 2007 though it falls between the 2006 and 2008 range...
select * From dbname..tbl where date>= '03/jan/2007' and date <= '11/feb/2008' and Status= 'C' and ID is not null
AND (ACCOUNT = '25869' or ACCOUNT = '0' + '25869' ) Check and post your comments ASAP...
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)
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.
I want to run a query that returns say 100 records...but I only want to return first 10 for first page on a web page, then on page 2 the webpage will return rows 11 to 20 of the same SQL statement...page 3 returns rows 21 to 30 rows etc....(eg. like Google or bulletin boards, browsing auctions in ebay etc.).
I could probably get my application logic to handle this (ASP.net), for instance I could possibly get a datareader to skip the first 10, output the next 10 then stop for page 2 (records between 11 amnd 20) but is there way to do this in SQL Server at the database level using an SQL Statement?
I can use TOP 10 to get the first set of records for the first page eg.
SELECT TOP 10* FROM Suppliers
...but how do I get between 11 and 20, 21 and 30 and so on?
I've already mentioned I could handle this in my application logic, but then each time the same SQL Statement is fetching all 100 records, even though the web page will only display a certain range. I'm building an intranet website that can potentially run queries that return 100'000s records, even though initially only top 20 or so records are display, each page they subsequently go to will rerun that same query that returns all 100'000 records. So handling this as part of the query would be better for performancr I reckon.
I'm trying to construct code that will return the last non-NULL value in a column containing daily records.
For E.G. I want to know what the LAST value of Description field when it is not NULL, AND the Date is within the range t=1 to t=5 => i.e. "Dog" in the below example:
Data(id int, product_id int, property_id int, value float)
Data.id references Headers.id
Headers.id is a primary key, Data has clustered index (id, product_id, property_id)
Headers has several thousand rows, Data several million. I want to return all rows from Data for a given product_id and a given property_id such that Header.id is in a given range.
Right now I am doing
SELECT id, time, value FROM Headers H, Data D WHERE H.id = D.id AND H.time >= @StartTime AND H.time <= @EndTime AND D.product_id = @ProductID AND d.property_id = @PropertyID
This query can take 10+ seconds to run, though once I run it for a given product_id, queries for different values of property_id are much faster. Try a different product_id, and it takes longer. Given that there are millions of records in Data, is it reasonable for it to take this long? The index was suggested by Query Analyzer's Index Tuning Wizard, and I tried a couple variations on the query without any noticeable performance improvement. But, I'm no DBA...anyone have any tips? I googled a bit but couldn't figure out the right way to phrase my question to find any good info...thanks in advance
Hello all, thanks in advance for any help you might be able to give.
I'm familiar with the Top command but I need something else to help in a project I'm working on.
I would like to select rows 1 through 100000 from a specific table in one query then 100001 through 200000 in a second query and 200001 through 300000 in a third and so on until I have gone through all rows. There happens to be 424000 in the table I'm working on.
I need to be able to select records based on dates that are before a certain date. That bit's easy, my problem is that this certain date needs to be the current date. Any body be able to help?
I'm trying to get a list of dates (actually, only the mondays) between a given range of two dates.Any help on the SQL statements I need to use, I'm having no luck.Thanks in advance.
Is there a way that I can get a resultset that contains unique dates ina given date range without the need to have a temporary table and acursor?perhaps something like:declare @start_date as datetimedeclare @end_date as datetimeset @start_date as '1/1/2005'set @end_date as '1/1/2006'select fn_getuniquedate(@start_date, @end_date)1/1/20051/2/20051/3/2005...12/31/2005
I'm migrating data from access 2003 to sql server 2005. An access table contains dates like 5/1/0999. This is a date that is out of the datetime range from sql server.
Now my question is ... How do I replace these dates? I don't find something like IsDate in the expressions?
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!
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
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]
Hi all,Right now I have this SELECT statement:SELECT MUSIC_PK, MUSIC_TITLE, MUSIC_TITLE2, MUSIC_ORIGINAL_SINGER Now I want to add a second SELECT statement (same as above, but with an additional column) if the record was added within the 10 days (while still select other records, I just need to select an additional column). How would I do that? The additional column that I want to select is called MUSIC_NEW (so I can display if the record is new within 10 days.) I have a column in my table named DATE_ADDED, how do I go to calculate if it's within the 10 days since the day it was added to the current time?Thank you very much,Kenny.
I currently have a stored procedure that returns a list of dates based on a date range a user enters.
CREATE PROCEDURE sp_GetContactScheduleDates @MonthFrom int, @YearFrom int, @MonthTo int, @YearTo int, @DaysInMonth int AS Select distinct s.ScheduleMonth, s.ScheduleYear From OnCall_Schedules s Where CAST(cast(s.ScheduleMonth as nvarchar) + '/' + cast(s.ScheduleDate as nvarchar) + '/' + cast(s.ScheduleYear as nvarchar) as smalldatetime) >= CAST(cast(@MonthFrom as nvarchar) + '/' + cast('01' as nvarchar) + '/' + cast(@YearFrom as nvarchar) as smalldatetime) And CAST(cast(s.ScheduleMonth as nvarchar) + '/' + cast(s.ScheduleDate as nvarchar) + '/' + cast(s.ScheduleYear as nvarchar) as smalldatetime) <= CAST(cast(@MonthTo as nvarchar) + '/' + cast(@DaysInMonth as nvarchar) + '/' + cast(@YearTo as nvarchar) as smalldatetime) Order by s.ScheduleYear, s.ScheduleMonth GO
However, this only brings back those dates that are in the table. I need to get ALL dates within the range.
For example, the OnCall_Schedules table contains schedules that are saved by the user. If no one has ever saved a schedule at any time in May 2004 and the range of dates entered is January 2004 to June 2004, then May 2004 will not be returned. I need to get back all dates within that range regardless if it has something scheduled or not. How can this be done?
Note - I do not want to set up any dummy records or create a table with valid dates as the user will be allowed to choose any range of dates and we do not want to have to maintain anything.
Can some sort of function be used? What would the code look like?
I am currently working in the sql server 2000 environment and I want towrite a function to pull all dates within a given date range. I havecreated several diferent ways to do this but I am unsatisfied withthem. Here is what I have so far:declare @Sdate as datetimedeclare @Edate as datetimeset @SDate = '07/01/2006'set @EDate = '12/31/2006'select dateadd(dd, count(*) - 1, @SDate)from [atable] vinner join [same table] v2 on v.id < v2.idgroup by v.idhaving count(*) < datediff(dd, @SDate, @EDate)+ 2order by count(*)this works just fine but it is dependent on the size of the table youpull from, and is really more or less a hack job. Can anyone help mewith this?thanks in advance
HiI have a table in my database called 'tblUsers'It contains usernames and a few columns of data.One of them in 'birthday'it is in the format dd/mm (ie 28/04 is 28th of april)it is always 5 characters longIts data type is char in my db.Now I try this<asp:SqlDataSource ID="SqlDataSource8" runat="server" ConnectionString="<%$ ConnectionStrings:IntranetConnectionString %>" SelectCommand="SELECT DisplayName FROM [tblUsers] WHERE ([Birthday] = @ShortDate)"> <SelectParameters> <asp:ControlParameter ControlID="Calendar1" Name="ShortDate" PropertyName="SelectedDate" Type="string" /> </SelectParameters> </asp:SqlDataSource>where the selected date from a calendar control is used.Now it works when the table has a Date column which is off type DateTime but how would I modify it to work like I want?Thanks!
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.
I'm using SQL Server 2000 sp2...I have created a view that gives me customer info from which I need to create a view and or table that gives me a 24 monthly columns of the sum of each account_number monthly revenues (going back 24 months from this month)..The columns I'm pulling from are these:
Here's what I have so far: ---------------------------- SELECT TOP 100 PERCENT Account_number, Customer_Name, SUM(Order_net_price) AS 'CM - 24' FROM dbo.Customer_Feed WHERE (First_insert_date >= DATEADD(mm, DATEDIFF(mm, 0, GETDATE()) - 24, 0)) AND (First_insert_date < DATEADD(mm, DATEDIFF(mm, 0, GETDATE()) - 23, 0)) GROUP BY Account_number, Customer_Name ORDER BY Account_number
I've basically hacked out a way to get the monthly totals for each account. What I would like to do is so be able to repeat the query but increment the date range 1 month until reaching the present or last FULL month and display these sums in individual columns named CM - n (where CM means current month and 'n' is the # of months back from current.how to make this query run over again the 23 other times I need it to and display those months sum totals in individual columns.
How to show the dates in between a range. Its hard for me to explain so I have ddl with the original results and then ddl of how I would like the desired outcome.
On the side I have a visit ID I need to show each day logged for each ID. Sometime the Start and End are a single day and sometimes they are a range. I need a row for each date.
Basically, I have a membership table that lists each member with an effective period, Eff_Period, that indicates a month when a member was active. So, if a member is active from Jan to Mar, there will be three rows with Eff_Periods of 201501, 201502 and 201503.
All well and good.But, a member may not necessarily have continuous months for active membership. They might have only been active for Jan, Feb and Jun. That would still give them three rows, but with noncontinuous Eff_Periods; they'd be 201501, 201502 and 201506.There is also a table that logs member activity. It has an Activity_Date that holds the date of the activity - betcha didn't see that comin'. What I'm trying to do is determine if an activity took place during a period when the member was active.
My original thought was to count how many rows a member has in the Membership table and compare that number to the number of months between the MIN(Eff_Period) and the MAX(Eff_Period). If the numbers didn't matchup, then I knew that the member had a disconnect somewhere; he became inactive, then active again. But, then I thought of the scenario I detailed above and realized that the counts could match, but still have a discontinuity.So, is there a nifty little SQL shortcut that could determine if a target month is contained within a continuous or discontinuous list of months?
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!!!
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.
I have three tables: EMP (ID, NAME), EMPDATE (ID, STARTDATE, ENDDATE), YEAR(YEAR)
I would like to get the most recent date within a given year per each EMP? For example, EMPID 1 can be enrolled in many programs, each program has start end dates. I need to list the most recent date an employee was enrolled (max date between START AND END DATE which ever is most recent enrollment) for a given year. For example, for 2014 his/her most recent enrollment should be 10/23/2014 for year 2014 and 2013-10-24 for year 2013.
SELECT ID, EMP.NAME, DTE.StartDate, DTE.ENDDATE, year FROM EMP_DATE DTE join EMP_INFO EMP on EMP.ID = DTE.ID join YEAR YR on YR.YEAR = YEAR(DTE.STARTDATE)
My scenario is: a person has many events, all based on a date. I need to aggregate the person to show min and max dates for a period, the period being defined as ending when there is not an event following the next date.
