SQL Server 2008 :: Calculate Number Of Months Between Dates For Multiple Records?
Oct 7, 2015
I have a challenge and I'm not sure the best route to go. Consider the following dataset.
I have a table of sales. The table has fields for customer number and date of sale. There are 1 - n records for a customer. What I want is a record per customer that has the customer number and the average number of months between purchases. For example, Customer 12345 has made 5 purchases.
CustomerNumber SalesDate
1234 05/15/2010
1234 10/24/2010
1234 02/20/2011
1234 05/02/2012
1234 12/20/2012
What I want to know is the average number of months between the purchases. And do this for each customer.

My data has 2 fields: Customer Telephone Number, Date of Visit.
Basically I want to add a field ([# of Visits]), which tells me what number of visit the current record is within 6 months.
Customer TN | Date of Visit | # of Visits (Within 6 month - 180 days)
1111 | 01-Jan-2015 | 1
1111 | 06-Jan-2015 | 2
1111 | 30-Jan-2015 | 3
1111 | 05-Apr-2015 | 4
1111 | 07-Jul-2015 | 3
As you can see, the last visit would counts as 3rd because 180 days from 07-Jul-2015 would be Jan-8-2015.

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.

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.

I need to find the missing months in a table for the earliest and latest start dates per ID_No. As an example:
create table #InputTable (ID_No int ,OccurMonth datetime)
insert into #InputTable (ID_No,OccurMonth)
select 10, '2007-11-01' Union all
select 10, '2007-12-01' Union all
select 10, '2008-01-01' Union all
select 20, '2009-01-01' Union all
select 20, '2009-02-01' Union all
select 20, '2009-04-01' Union all
select 30, '2010-05-01' Union all
select 30, '2010-08-01' Union all
select 30, '2010-09-01' Union all
select 40, '2008-03-01'
For the above table, the answer should be:
ID_No OccurMonth
----- ----------
20 2009-02-01
30 2010-06-01
30 2010-07-01
1) don't include an ID column,
2) don't use the start date/end dates in the data or
3) use cursors, which are forbidden in my environment.

I am looking for a formula to calculate the number of weekdays/business days between two dates in power pivot.I do the same in SQl using the following query
DATEDIFF(dd, Date1, GETDATE()) - (DATEDIFF(wk, Date1, GETDATE()) * 2) -
CASE WHEN DATEPART(dw, Date1) = 1 THEN 1 ELSE 0 END +
CASE WHEN DATEPART(dw, GETDATE()) = 1 THEN 1 ELSE 0 END END
I am looking for a similar query in Power Pivot.

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.

I have a table of Customers & their data in about 20 Columns.
I have another table that has potential Customers with 3 Columns.
I want to append the records from Table 2 onto Table 1 to the Columns with the same names.
I've thought of using UNION ALL or Select Insert but I'm mainly stuck on the most efficient way to do this.
There is also no related field that can be used to join the data as these Customers in table 2 have no Customer ID yet as they're only potential Customers.
Can I just append the 3 columns from Table 2 to the same 3 columns in table 1?

I have a table of customer sales (dbo].[CustomerSales] which has a complete record od sales of our products for the past 5 years. I would like to create a report that extracts all the sales per customer on one row ie [CustomerID] 00011 has had 25 sales in the past 5 years and I would like to have their sales from left to right (starting with their earliest sale date at the beginning [SaleDate] field on the one row. I would also like to include the store location field [Location] along with the date the sale took place. So in other words the extract would look something like:
[CustomerID], [SaleDate], [Location], [SaleDate], [Location], [SaleDate], [Location], [SaleDate], [Location], [SaleDate], [Location], etc etc
Obviously some customers will have had less sales than others in which case I’m assuming these fields would just contain NULL values.

INTO a single record:

Ok, I'm looking to get counts on historical data where the number of records exists between two dates with different years. The trick is the that the dates fall in different years. Ex: Give me the number of records that are dated between 0ct 1, 2013 and July 1, 2014.
A previous post of mine was similar where I needed to get records after a specific date. The solution provided for that one was the following. This let me get any records that occured after May 1 per given Fiscal year.
SELECT
MAX(CASE WHEN DateFY = 2010 THEN Yr_Count ELSE 0 END) AS [FY10],
MAX(CASE WHEN DateFY = 2010 THEN May_Count ELSE 0 END) AS [May+10],
MAX(CASE WHEN DateFY = 2011 THEN Yr_Count ELSE 0 END) AS [FY11],
MAX(CASE WHEN DateFY = 2011 THEN May_Count ELSE 0 END) AS [May+11],
MAX(CASE WHEN DateFY = 2012 THEN Yr_Count ELSE 0 END) AS [FY12],
[Code] ....
I basically need to have CASE WHEN MONTH(OccuranceDate) between Oct 1 (beginning year) and July 1 (ending year).

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

I am stuck on a query where I need to display all the month year values even if the corresponding count_booking values are NULL. The requirement is to display the 13 month year period from current date.
For e.g. if the date exists in the current month then starting from May 15 go all the way back to Apr 14.
My current query works in terms of displaying all the 13 months if the count_booking values exist for all the months. However, if some months are missing the values then those months don't show up.how to display all the months even if the values are NULL ? Query below:
SELECT COUNT(m.BOOKING_ID) AS count_booking, LEFT(DATENAME(MONTH, m.CREATE_DT), 3) + ' ' + RIGHT('00' + CAST(YEAR(m.CREATE_DT) AS VARCHAR), 2)
AS month_name

I'm trying to write some code that will get me the last day of each month for the months that fall between 2 dates.
So if i have a table with a record with a begin date of 01-01-2012 and an end date of 09-14-2012, i would want a result set of the following 9 records:
01-31-2012
02-29-2012
03-31-2012
04-30-2012
05-31-2012
06-30-2012
07-31-2012
08-31-2012
09-30-2012
So i basically get the last day of each month between the dates listed, including the months that the dates are in themselves (inclusive list).
I have a date dimension table with 1 row for every day from 1990 to 2025. There is also a field with the Last day of Month for a given date. My issue is that I'm not sure how to write the T-SQL to get what I need.

Hello,
I have created a Table Called Log in SQL Server 7. I use this table as you can guess to log all transaction performed in my program. However, I would like my program to run an SQL Statement that will flush all entries in the table Log that are 6 months old from today's date.
I am unable to find the statement that will execute this operation.
Anyone has an idea please.
