Transact SQL :: How To Generate Date Ranges From Given List Of Dates
Sep 10, 2015
I want generating Valid date ranges from any list of dates.
The List of Dates could be generated from the below TSQL -
SELECT '2015-06-02' [Date] UNION ALL
SELECT '2015-06-13' UNION ALL
SELECT '2015-06-14' UNION ALL
SELECT '2015-06-15' UNION ALL
SELECT '2015-06-16' UNION ALL
SELECT '2015-06-22' UNION ALL
SELECT '2015-06-23' UNION ALL
SELECT '2015-06-24'
And the expected output should look like -
SELECT '2015-06-02' FromDate, '2015-06-02' ToDate UNION ALL
SELECT '2015-06-13' FromDate, '2015-06-16' ToDate UNION ALL
SELECT '2015-06-22' FromDate, '2015-06-24' ToDate
i have a table like below CREATE TABLE #Test (FromDate DATE,ToDate DATE) insert into #Test VALUES ('2015-08-08','2015-08-11') insert into #Test VALUES ('2015-08-13','2015-08-16') insert into #Test VALUES ('2015-08-19','2015-08-21') SELECT * from #Test drop TABLE #Test
i need to display the dates as single column between from and todate.my expected result is like below
CREATE TABLE #Result (ResDate DATE) insert into #Result VALUES ('2015-08-08') insert into #Result VALUES ('2015-08-09') insert into #Result VALUES ('2015-08-10') insert into #Result VALUES ('2015-08-11')
I understand how to find (generate) missing dates for the year 2006 if I have a range value like 1-1-2006 to 3-1-2006. (I'm just using 2006 for arguements sake - the needed approach starts back in 2004 or so and will extend to the current day)
Now the question that presents itself is, is there an elegant way to do this same process with an arbitrary number of date ranges per customer? There would be 1 record per range, per customer
What I'd like to generate is a record per missing date in 2006, which would be: 4 records for 1-1-2006 to 1-4-2006 several records for 2-1-2006 to 10-31-2006 and then more for 11-18-2006 to 12-14-2006
As I said before, the number of ranges isn't static. It could be 1 or a dozen and could increase as time goes on. At this time, all I can see to potentially make it work in query is to do a dozen joins - which kind of sucks.
My other thought is to do specific processing per customer, per range gap, but it will be terribly slow.
I need to generate the week ranges like this format :
Here from date and to date would be picked up from the table but just to make you understand i have hard coded it but this is the real date which is falling inside the table.
Note : Week should be generated from Monday to Sunday within desired date range
I have to insert YEAR WEEKNUMBER STARTDATE ENDDATE values to a datatable (sayweekrange), if I pass 2011 as year.
Week range starts at 2011-03-28 to 2011-04-03 (because in my database 2010 last week range ends with 2011-03-27) like this I have to generate for 52 weeks.
I want to write a stored procedure, that takes only year as parameter. with this year I have to generate week ranges and insert into my table as shown above.
I had to enable identity_insert on a bunch of tables and I have already done that. Now I need to modify my insert into select * from statements to include column list names along with identity columns for select as well as insert statements. The DDL is same but they are both different databases.There are almost 100 tables that it needs to be modified. Is there a way we can generate scripts for insert and select for each individual table along with their column lists including the identity column?
Hi all,I have a problem trying to generate the u/m list of customer.I am trying to generate a list of customer whoes last commence date isjan 04 to current.It is part of a billing system which the customer come in and pay fortheir season parking in carpark.

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?
Select datediff(dd,Target_Date,Achv_Date) Now , checks are 1] when target date greater than achv_Date the difference should be greater than 0 means for FileID 77608 Select datediff(dd,'2015-09-24 00:00:00.000','2015-09-24 10:42:32.823')
i am getting -6 it should be 6 cant switch Target_Date and Achv_Date in datediff else i will get opposite result in first four records basically, i want a two column TAT and Status beside achv_date based on the values of two dates difference see above ..and also want a result of (No. of Yes in status / No. of Files that has achv_date )i.e. result= (7/8) = 87%
I have a simple following table which is having only one date column.
CREATE TABLE TEST_DATE ( InputDate DATE ) GO INSERT INTO TEST_DATE VALUES('01-01-2015') INSERT INTO TEST_DATE VALUES('06-25-2015') INSERT INTO TEST_DATE VALUES('11-23-2014') GO SELECT * FROM TEST_DATE;
And the expected out put would be as follows:
I want to derive a Four Quarter End Date based on Date selected.
For Example if i select 01-01-2015 then First Quarter End Date would be Previous Quarter End Date Second Quarter End Date would be Current Quarter End Date Third Quarter End Date would be Next Quarter End Date Fourth Quarter End Date would be Next +1 Quarter End Date Like that
I need to calculate the amount of time between each visit. I am pulling the Row Number for my visits and now I need the date span that goes between each day. I also need a new column that returns a Yes or a No if the date span exceeds 3 years.
SELECT ROW_NUMBER ( ) OVER ( PARTITION BY pv.PatientProfileId ORDER BY pv.Visit ASC ) AS RN , CONVERT ( VARCHAR ( 20 ) , pv.Visit , 101 ) AS Visit , pv.TicketNumber , vstatus.Description AS VisitStatus , doc.ListName AS Doctor
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.

For this id: 0793319, my beginning date is 2011-09-06
108203492014-09-022015-06-30 208203492013-09-032014-09-01 308203492012-09-042013-09-02 408203492011-12-122012-07-03--not a continuous date range
For this id: 0793319, my beginning date is 2012-09-04
108203492014-09-022015-06-30
For this id: 0820349, my beginning date is 2014-09-02
To find continuous date, you look at the beginning date in row 1 and end date in row 2, then if no break in dates, row 2 beginning date to row 3 end date, if no break continue until last date There could multiple dates up to 12 which I have to check for "no break" in dates, if break, display beginning date of last continuous date.
I have a table which records employees'time-off records. There are 6 columns in this TimeOff table. They are RequestID, EmpName, StartDate, EndDate, Type, NumofDays. I have another table which has all the dates from 01/01/1950 to 01/01/2056.
I am trying write a query which lists all the dates between the timeoff startdate and enddate, including the the start and end dates, but my query so far only lists the start and end date in a timeoff record:
SELECT D.[Date], Datename(dw,D.[Date]) AS Weekday FROM Dates D LEFT JOIN TimeOff T ON D.[Date] = T.OffStartDate OR D.[Date] = T.OffEndDate WHERE (OffType = 'Sick Day' AND EmpName = 'Cat White') AND (D.[Date] BETWEEN T.StartDate AND T.EndDate)
Can someone please help me with this? I need a query that will pull clients that made payments last year but not this year. I need the query to use date parameters so I can select any date range for the past year and the current year. I have listed the tables and fields that might be needed: I'm hoping to do this without temp tables. Date range is based on the tblPaymentReceipts.PaymentDate tblClients, ClientID tblPayment, PmtID, ClientID, Paystartdate, Paygroup tblPaymentReceipts, PmtRcptID, PmtID,CleintID,PaymentDate,PaymentAmount
I have two sets of dates to work with. One is an existing booking with a start and an end date. The other is a new booking with a start and an end date. I want to compare them and calculate how much overlap there is. If the overlap is over a certain amount (say 4 days), then I want to flag the user.
Is there any thing I can use in terms of a SQL query to assist in this comparison? I'm relatively new to SQL so I'm not entirely sure what functions and keywords are available to me to make this comparison.
I've gone cold here. Dunno if I've had too little coffee - as I'm currently drinking some seriously wicked green tea - or whether my brain has locked down from yesterdays "bad eggs for lunch" experience.
Anyway... I have database with a customer, for each customer is a related history table with assigned consultant.
The assigned consultant table has information on consultant id, name, the start date of his assignment and the end date.
I need to find all customers that currently have (or have had) two or more consultants actively assigned. In other words, I need to see if the start/end times overlap.
At my current state, I'm just done.. i can't maintain the perspective... how do I do this?
I woudl like to take an age range (Say 22-27) and determine the min and max year, and then take those two DateTime Year values and do a SELECT from a column titled "Birthday Year", which is a an int value like '1984'. Could someone give me a hand with this?
/* Value 1: 1978 Value 2: 1988 */
SELECT(???) FROM User WHERE ['BirthdayYear'] <> (?Age Function?) GO
I have a set of MS SQL reports, that need to always run on a certain day of the month. Generally the 20th. If the report was to run few days before the 20th, say on the 10th, I wish to retrieve those days between the 20th from the previous month, till the current date.
e.g: '2015-4-10' should only return 20 days worth of data.
I have tried the following query:
SELECT DATEADD(D, 1, MAX(CAST(DateTimeStamp AS DATE))) As EndDate, MIN(CAST(DATEFROMPARTS(DATEPART(YEAR, DateTimeStamp),DATEPART(MONTH, (SELECT CASE WHEN DATEDIFF(DAY,DATEPART(DAY, GETDATE()),28) <0 THEN (SELECT DATEPART(MONTH, GETDATE())) ELSE (SELECT DATEPART(MONTH, GETDATE()) -1) END AS Date)),28)AS DATE)) AS StartOfMonth
FROM tbLogTimeValues WHERE DATEPART(YEAR, DateTimeStamp) = DATEPART(YEAR, DATEADD(M, -1, GETDATE()))
Which parses ok and managed to test all individual queries, however, as a whole, I get the following error message "Cannot perform an aggregate function on an expression containing an aggregate or a subquery."
Hello,I am importing data that lists rates for particular coverages for aparticular period of time. Unfortunately, the data source isn't veryclean. I've come up with some rules that I think will work to clean thedata, but I'm having trouble putting those rules into efficient SQL.The table that I'm dealing with has just under 9M rows and I may needto use similar logic on an even larger table, so I'd like somethingthat can be made efficient to some degree using indexes if necessary.Here is some sample (simplified) code:CREATE TABLE Coverage_Rates (rate_id INT IDENTITY NOT NULL,coverage_id INT NOT NULL,start_date SMALLDATETIME NOT NULL,end_date SMALLDATETIME NOT NULL,rate MONEY NOT NULL )GOINSERT INTO Coverage_Rates VALUES (1, '2004-01-01', '2004-06-01',40.00)INSERT INTO Coverage_Rates VALUES (1, '2004-03-01', '2004-08-01',20.00)INSERT INTO Coverage_Rates VALUES (1, '2004-06-01', '2004-08-01',30.00)INSERT INTO Coverage_Rates VALUES (2, '2004-01-01', '9999-12-31',90.00)INSERT INTO Coverage_Rates VALUES (2, '2004-03-01', '2004-08-01',20.00)INSERT INTO Coverage_Rates VALUES (2, '2004-08-01', '2004-08-01',30.00)GOThe rule is basically this... for any given period of time, for aparticular coverage, always use the coverage with the highest rate. So,given the rows above, I would want the results to be:coverage_id start_dt end_dt rate----------- ---------- ---------- --------1 2004-01-01 2004-06-01 40.001 2004-06-01 2004-08-01 30.002 2004-01-01 9999-12-31 90.00There can be any combination of start and end dates in the source, butin my final results I would like to be able to have only one distinctrow for any given time and coverage ID. So, given any date @my_date,SELECT coverage_id, COUNT(*)FROM <results>WHERE @my_date >= start_dtAND @my_date < end_dtGROUP BY coverage_idHAVING COUNT(*) > 1the above query should return 0 rows.Thanks for any help!-Tom.
I have a strange problem that I haven't dealt with before.
I need to execute a piece of code based on date ranges. If the date range is:
Scenario 1:between 02/28 (Feb 28) and 07/31 (July 31) do x ----------------------------------------------------------- Scenario 2:between 08/01 (Aug 1) and 01/31 (Jan 31) do y
I am trying to automate a report. The report is supposed to generate a result that will differ based on the date ranges going into the future. E.g.
[1]. If the run date of the report is between '2/1/20xx' and '7/31/20xx' display <ABC> or
[2]. If the run date of the report is between '8/1/20xx' and '1/31/20xx' display <PQR>
In example # 2. I am moving from one year to the next (July to Dec and the one extra month of Jan). So for example, if the guy runs the report between August of 2008 and January of 2009, display <PQR>.
How do I achieve both # 1 & 2 above in a code? Does this explain better.
I'm currently using Reporting Services for SQL Server 2005. I have been able to setup, and configure the Report Manager interface, as well as generate reports via the Report Builder. What I have been unable to do is allow the user to dynamically set the date range that my SQL query will use. Can someone suggest / is it even possible wihtout using a custom web interface?
We have some seasonal products that we would like to turn on and off automatically on our website. To accomplish this, we've added StartDate and EndDate fields to the product table. See simplified table: --------------Simple Table:--------------ID int identity (PK)Value varchar(50)StartDate datetimeEndDate datetime Normally I could just do something like SELECT ID, Value FROM PRODUCTS WHERE StartDate <= @MyDate AND EndDate >= @MyDate The catch is that we want to ignore the year part of the dates so that we don't have to go back through and update all the records every year. I'm pretty sure I've done this in the past, but I'm having a brain fart right now and can't remember how. One of the issues is that the start month could be > the end month (e.g. - October 15 - January 1). Using code in the application I could work around this (see below), but I would like to handle this in SQL if possible so I don't have to return more records than are needed and weed out the bad records. 'dtStart and dtEnd are Date Objects, StartDate and EndDate are strings containing the MM/DD partIf dtStart.CompareTo(dtEnd) > 0 And dtStart.CompareTo(myDate) < 0 Then dtEnd = Date.Parse(EndDate & "/" & (myDate.Year + 1))ElseIf dtStart.CompareTo(dtEnd) > 0 And dtStart.CompareTo(objDate) > 0 Then dtStart = Date.Parse(StartDate & "/" & (myDate.Year - 1))End If I appreciate any help you can provide. Thanks,Sam
Hello, I am trying to automate our FTE calculations, and I need to be able to determine the total days employed for a given employee for a given period of time. I have the date ranges they worked, but am not sure how to total those based on the required period, For example
empployee|Start Date|End Date 1|1/1/2005|3/1/2006 1| 4/15/2006| 1/1/2008
How do I total the number of days employed for this employee between 2/1/2006 and 2/1/2007?
Guys I want to get the date ranges instrument wise for which the instrument readings are constant.
For example for instrument 1 the readings are constant i.e 10 from 10/12/2008 till 12/12/2008 & then again it is constant from 14/12/2008 till 17/12/2008. Same goes for instrument id 2.It is constant from 07/03/2008 till 20/03/2008. I need to get the output like this.
Just want to check if my query is the standard way to check if date ranges overlap in a price table as I need to check any that overlap as I can't have two prices on one day.
For example if in a table there was:
Product TROUSER Colour BLUE Start Date 01-NOV-13 End Date 20-NOV-13 Price £20.00 Start Date 10-NOV-13 End Date 12-NOV-13 Price £18.00 Start Date 21-NOV-13 End Date 25-NOV-13 Price £15.00
The top two overlap.I'm doing this which is giving me nothing returned which I'm hoping means I have no overlapping date ranges:
