Transact SQL :: Finding Unique Counts Based On Consecutive Days?
Jul 9, 2015
I have a scenario here where the data looks like -
ID Date
100 07/01
100 07/02
100 07/03
100 08/01
100 08/02
100 08/15
Now I need to find out unique occurrences of ID - 100 ( where count = unique only if the occurrences are in consecutive days, gap of even 1 day causes it to be a different instance ) - SO with the above data I should have unique occurrences as 3.efficient way to calculate this ?

I have 2 tables A, B with 1 to many relationship
Table A(ProductID), TableB(ProductID, FileID)
I need to find only the records in Table A that may have more than one FileIDs in Table B, since some ProductIDS have multiple FileIDs in Table B...

6 Peter Jason 5/1/2015 321.02
7 Peter Jason 5/23/2015 123.02
May be we may do by dense_rank or Row_Number, but I couldn't get the exact query to produce based on the above table values. There are some duplicates in the table(which are not duplicates as per the Business). For those duplicated Unique ID should be same(Marked in Orange Color which are duplicates).

Hello,
I have a table with 3 columns: Item# | Date | ItemAmount.
Everyday there is a number of transactions entered. An Item# can only be entered once par day (if it has occurred that day).
What I want to do is to :
retrieve the number of total days where an Item has been entered for more than 2 consecutive days (for the month).
Example: if item I022 has been entered Monday and wed, then ignore, but if it's been entered Mon, Tues then return 2, if Mon, Tues, Wed then return 3 because the days are consecutive.
Does anyone have an idea.
thanks in advance,

I want to display Days Hours Mins Format.
I am Having two columns Like below,
Col1 (in days) col2 (In Hours : Mins)
3days 4:5
In this first have to add Col1 and Col2 (Here one day is equals to 9 hours ) so the addition is 31.5
From this 31.5 I should display 3 Days 4 Hours 30 Mins because 31.5 contains 3 (9 hours) days 4 Hours and .5 is equals to 30 mins.

We have customer accounts that we measure usage. We want to run a report for all customers whose current usage is 0 and a count of how many months it has been zero consecutively. Here is an example.
declare @YourTable table (
CustomerID int,
ReadDate datetime,
usage int
)
insert into @YourTable select 1,' 1 mar 2014',0
insert into @YourTable select 1,' 1 feb 2014',0
[Code] ....
This should return

This is what I am currently using but it isn't working right

I have a data set that looks something like like this:
Row# Data
1 A
2 B
3 B
4 A
5 B
6 B
7 A
8 A
9 A
I need wanting to assign a group ID to the data based on consecutive values. Here's what I need my data to look like:
Row# Data GroupID
1 A 1
2 B 2
3 B 2
4 A 3
5 B 4
6 B 4
7 A 5
8 A 5
9 A 5
You'll notice that there are only two values in DATA but whenever there is a flip between them, the GroupID increments.

I am trying to determine the amount of days in a month to prorate a month end estimate.
We measure service calls and need to approximate how many we will have at month end.
I would like to automate a query to post on our web and need to know how many days are in the current month.
A possible solution would be to piece together a datetime variable using getdate and dateadd then use a datepart.
However , I don't know how to create a datetime variable this way.
Thanks in advance

Hi and Thank you in advance
I am trying to find a away to calculate the number of business days between two dates. In other word, I do not want to count Saturday nor Sundays if those days are between the two dates.
Example
if Date1 = 11/26/1999
Date2 = 11/30/1999
the DateDiff(dd,Date1,Date2) the result should be 2
I need to do this against a table which might not have a lot of records, but I also need to not count Holidays if they fall within the two Dates.
Thank you in advance

In my query I have a date field and using that date field I want to pass the date to a function, or whatever is most appropriate, then compare that date with a range of the last 4 weeks, which will be numbered 1-4, 1 being earliest and 4 being latest, and then return the week number.
I've determined I need some sort of look up but will need to be dynamic - thinking maybe a temp table, first using the date the report is run on and counting 28 days back from the most recent last saturday then setting number to 1 for first 7 days then 2 for next 7 days etc.

I am trying to create a query that outputs the following data from multiple tables. Here is an example of the raw data right now
Date | MachineNumber | TestName
---------------------------------------
1/1/2015 | 500 | Something
1/1/2015 | 500 | Something
1/1/2015 | 500 | Something
1/1/2015 | 500 | Something
1/1/2015 | 510 | NewTest
1/1/2015 | 510 | NewTest
1/1/2015 | 510 | NewTest
1/1/2015 | 620 | Test#1
Here is the desired counted output, I would like to pull distinct Date, MachineNumber, TestName and then count how many times they occur in the raw data form.I do need to perform a case on the date because right now its in a datetime format and I only need the date.
Date | MachineNumber | TestName | TestOccuranceCount
-----------------------------------------------------------------
1/1/2015 | 500 | Something | 4
1/1/2015 | 510 | NewTest | 3
1/1/2015 | 620 | Test#555 | 1
I am pulling three columns with the same names from 8 different tables. What I need to display the date, machine & test name and count how many times a test was run on a machine for that date. I have a feeling this can be handled by SSAS but haven't built an analysis cube yet because I am unfamiliar with how they work. I was wondering if this is possible in a simple query. I tried to set something up in a #Temp table. Problem is the query takes forever to run because I am dealing with 1.7 Million rows. Doing an insert into #temp select columnA, columnB, columnC from 8 different tables takes a bit.

I have simple query that works fine if I write it every time. I want to get this one time group by each year and week ending. here us the query:
Select count(distinct ID) from table1 where year<=2015 and WeekEnding<='05/09'
Select count(distinct ID) from table1 where year<=2015 and WeekEnding<='05/16'
Select count(distinct ID) from table1 where year<=2015 and WeekEnding<='05/23'
How can I get the count for each week year and each week ending? Weekending 05/16 will include ID's from weekending 05/09 as well and week ending 05/23 will include all the ID's from 05/16 and 05/09 and so on...

how to find all possible combinations of values, for example:
My table includes:
Code:
CREATE TABLE temp1 (item varchar(50), ORDER int);
INSERT INTO temp1 (item, order) VALUES ('apple',1);
INSERT INTO temp1 (item, order) VALUES ('pear',2);
INSERT INTO temp1 (item, order) VALUES ('blueberry',3);
I need the output to be like this:
apple
pear
blueberry
apple, pear
apple, blueberry
pear, blueberry
apple, pear, blueberry
I don't need the reverse of each. For example, I need only 'apple, pear'... I don't need 'pear, apple'.

I am using Access 2007 and I have 10 columns of data.
I am trying to select all the data from all 10 columns where the first column's data returns only the Unique values and the other columns return all the data from the row that is returned from the first column.
I have used this
SELECT DISTINCT [SFR Rates All].Sorter, [SFR Rates All].SProgram, [SFR Rates All].S_Price, [SFR Rates All].Min_Loan, [SFR Rates All].Max_Loan
FROM [SFR Rates All];
But that returns all the data in the table and all values in the Sorter column with duplicates because each row has distinct data.
I am trying to return unique values from [SFR Rates All].Sorter (the first column) and all the data from the other 9 columns that are contain the row with the unique value in Sorter.
I know that I am missing something basic but well, I can't figure it out.
Thanks

I have the following variables VehicleID, TransactDate, TransactTime, OdometerReading, TransactCity, TransactState.
VehicleID is the unique vehicle ID, OdometerReading is the Odometer Reading, and the others are information related to the transaction time and location of the fuel card (similar to a credit card).
The records will be first grouped and sorted by VehicleID, TransactDate, TransactTime and OdometerReading. Then all records where the Vehicle ID and TransactDate is same for consecutive rows, AND TransactCity or TransactState are different for consecutive rows should be printed.
I also would like to add two derived variables.
1. Miles will be a derived variable that is the difference between consecutive odometer readings for the same Vehicle ID.
2. TimeDiff will be the second derived variable that will categorize the time difference for a particular vehicle on the same day.
My report should look like:
VehID TrDt TrTime TimeDiff Odometer Miles TrCity TrState
1296 1/30/2008 08:22:42 0:00:00 18301 000 Omaha NE

I am in a situation where I need to find out unique field names with different values in a table having 200+ columns.
Let's say I have two rows with 200+ columns ( I exported these rows from Lotus Notes to SQL Server) I am not sure what columns makes unique of these rows. It's going to be tedious by checking each column values.
Is there anyway I can write a squl query on these two rows which outputs column names which are having unique values.
I would appreciate If anybody gives me hint about achieving desired result

HI all,
I am having a bit of difficulty trying to work how to write a query. I am normally only used to doing SELECT, UPDATE and DELETE queries ... the simple ones.
However I have come across a query whereby things get a lot more complex.
My company has an employee table with a way to store data that I have not been used to.
EMPLID, NAME, DATELASTMODIFIED, EmployeeStatus. (There are lots more but N/A)
The problem that I have is that there can be more than one row for an employee id. Therefore I cannot uniquely identify an employee id. Instead what I have discovered I have to use is to find an employee with the last modified date higher than the other rows with the same employee id.
The query I am trying to achieve is:
Code:
Count all employees that have an employee status of 'Employed'.
(Therefore counting only one employee per id rather than counting the same employee more than once)
The trouble is, translating this into a SQL query. I have tried to have a go but don't know how to query:
Code:
SELECT COUNT (DISTINCT EmplId)[
FROM Employeetable AS e
WHERE e.LASTDATEMODIFIED <And Stuck>
AND EmployeeStatus = 'Employed'
So I thought hmm lets pseudo code this, but then I get stuck into compelixty:
Code:
SELECT * FROM EmployeeTable WHERE EmployeeStatus = 'Employed'
int counter = 0;
ForLoop (EmplId)
{
LastDate Date
if(LASTMODIFIEDDATE > LastDate)
{
LastDate = LASTMODIFIEDDATE
}
//How do I return the value? Do I count the value?
}
Has anyone come across this issue before? Can anyone help it quite fundemental to what I have to query so help on this is highly appreciative.

Hi,
I'm trying to query an SQL table column with date values to show 8 Days ago results.
I've started with this query:
SELECT ficheiro, erro, descritivo_erro, contrato, DO, movimento, data, descritivo, tipo_movimento, desconto, montante, comissao, IVA
FROM status_day
WHERE (YEAR(data) = YEAR(GETDATE())) AND (MONTH(data) = MONTH(GETDATE())) AND (DAY(data) = DAY(GETDATE()) -8)
ORDER BY descritivo_erro, contrato
The problem is that the text in red will have some problems when the month changes - If I want the 8 days ago results from January and the system date is 1st of February the query will not return any values.
I read something about DATESERIAL but is wasn't conclusive on how to use it with system date.
Please help me out with this query.

I have to produce a report to calculate no of days based on user input start date and end date. I have tried to explain below.
say for eg: in the tables I have emp name
user 'Phani' started work from - EStart 20/11/2014EEnd 10/01/2015 - total days --datediff
within his work period he did different roles:
PhaniMarketing (prSt Date) 20/11/2014prE date (28/11/2014) Total 9 days
PhaniAdmin (prSt Date) 29/11/2014prE date (20/12/2014) Total 22 days
PhaniCRM (prSt Date) 20/12/2014prE date (10/01/2015) Total 22 days
Total days 53 Days
For this :
I calculated datediff + 1 and got sub jobs days BUT
say financial director wants to see Title of 'Sub Jobs' with 'Days' from 1st Dec to 31st Dec
so on paper I calulated as :
1-31 Dec 2014
PhaniMarketing NULL (Do not fall in Req Dt)
PhaniAdmin 20 (Deduct 2 days of Nov & calculated 20 days of Dec)
PhaniCRM 11 (Deduct 20 days of Nov and deduct 11 days of Jan so for Dec , we got 11 days)
Total days 31
HOW CAN I USE Case statement to calculate days for given start date and end date. I have to include all three totals, 1 for Job dates, 2, subjobs dates, 3 cal of days for a requested period.

I don't immediately find if this is possible but hope someone can give me an answer:
is it possible to make a unique constraint over 2 columns but only when 1 column has a specific value ?
Example: table (tableid, instancetype, instancename, ..)
instancetype can be A or B
if it is A then instancename must be unique
but for B instancename is not unique as these are copies from A
only solution I can think of is to make a trigger on an insert to check what the instancetype is and do a select to see if the name already exists in the table or not..
are there other solutions to make a constraint like this ?

I'm trying to calculate the time difference between a date field and today's date in days. The date field is not mandatory and can therefore be blank. I'm trying to execute the following query:
SELECT employee_code, Civil_ID, DATEDIFF(Day, Civil_ID, GETDATE())
FROM ODEV_VIEW_Credentials_Expiry_Dates
WHERE Civil_ID IS NOT NULL AND Civil_ID != ''
ORDER BY employee_code
I keep getting the following message:
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
Warning: Null value is eliminated by an aggregate or other SET operation.
No matter what filter I use to process non-blank dates, it never works.
