I need to build a report which has week's sales data by department by date (which I have done using Matrix) and compare it to weeks sales last year. Report would be run weekly. I am wondering which approach would be most efficient:
1) generate separate data sets - 1) for 1 weeks data and 2) for 1
week a year ago and then compare these values;
2) create 1 data set for a period of 1 year + 1 week and insert
calculated fields in the data set;
3) create 1 data set for a period of 1 year + 1 week and insert
calculated fields with expressions inside the report
4) any other.
Thanks
If you tables are well indexed, then I'd suggest you go with the first approach - It'd reduce the data to be compared. I feel that pulling data from one year in past would be a less expensive than comparing 2 week's data out of one year's data.
You could use the week number of any given week to efficiently pull data for any week based on the date range.

Need help to get the data of particular format
We have a table which have a data which of production now we need to select the data of each day with particular time period which is differentiate between three shift A,B,C.
In our table we have a datetime column which capture's each seconds data now that data we need in shiftwise like 6am to 2pm is of A shift production count and 2pm to 10pm of shift B and 10pm to 6 am of shift C.
here i am getting the data for single day where i have written the below query which is working good.
select distinct(count(PRD_SERIAL_NUMBER)),(select convert(date,getdate())) as date,'B' as shift_name
from table_name
where status=02
and LAST_UPDATED_DATE
between (SELECT FORMAT(GETDATE(),'yyyy-MM-dd 14:01:00.000')) and
(SELECT FORMAT(GETDATE()-26,'yyyy-MM-dd 22:01:00.000'))
refer below output image 1
Here i am getting the count for single day and for upcoming days i have solution but now the question arise is i have a past 4 Month data which i need to get in datewise and shiftwise count and for the column prd_serial_number have duplicate entries so it should be in distinct.
please refer below image 2 for required output format
I have a table where I maintain working days in a week like 2nd and 4th day and number of records it can accept is 10 records per working day
usercode DaysofWeek NumberOfRecords
0623PO54 2 10
0623PO54 4 10
On insertion I have application date example 01-09-2017(dd/mm/yyyy) which is Friday.
Now I have to insert this record in closest working day from 01-09-2017 which is 05-09-2017 as it is 2nd working day. After inserting 10 records next records should be insert on 4th working day which is 07-09-2017.
I don't know how to get closest date from application date and insert record on it.
If you also want to exclude holidays than use a master table for Ex. CalenderMastr of dates which have holidays flag and day of week like Monday=2. and as you mansion that you are maintaining working days in a table for ex. workdaymaster. Now make a select query to get next date from CalenderMastr from current date and day of week stored in workdaymaster. now on output date check if in your transaction table count is smaller or not if count is small insert new record or if not than move to next date using while loop in your query. hope you can understand what i am trying to say.
I have a Month Column with the Month Field populated for each line for the 100K of lines of data I have.
I need to count the amount of times the Month Field is populated in the Previous Month (Period).
I also need to count the total amount of times the Month Field is populated in the Previous 11 months as well.
This is a rolling count for each months reporting that I do..
table name: 'ws pds' and field name [Month Tagged]
You can utilize the powerful time intelligence functions in DAX such as PARRALLELPERIOD to look at values from previous months. But in order to make use of these functions you need to create a calendar/date entity. Mark that entity as a Date table. And join to it by date from your "ws pds" table. The Date dimension should span the timeframe of your date with a continuous list of dates, one row per day.
Then your measure could look like this:
PreviousMonthCount=
CALCULATE (
COUNTROWS ( 'ws pds' ),
'ws pds'[Month Tagged] <> BLANK (),
PARALLELPERIOD ( Calendar[Date], -1, MONTH )
)
I have a table with more than 20000 rows, In one of column i have month from jan 2014 to Dec 2014, and in another column i have a loan number. Most of the loan Numbers are reapeting every months,now i need to get only the loan Number which are apperead in all three monthy consecutively. For eg if i am getting data for current months i also wanted get data which are common in two months before the current months. The database that i m using is Access DB. Any adivice will be more than a help, Thanks in Advance.
SELECT Loans.LoanID, Sum(IIf([period]=[month],1,0)) AS CM, Sum(IIf([period]=[month]-1,1,0)) AS [m-1], Sum(IIf([period]=[month]-2,1,0)) AS [m-2]
FROM Loans
GROUP BY Loans.LoanID
HAVING (((Sum(IIf([period]=[month],1,0)))>1) AND ((Sum(IIf([period]=[month]-1,1,0)))>1) AND ((Sum(IIf([period]=[month]-2,1,0)))>1));
I used month as an integer, and didn't make any adjustment for months 1 and 2 to loop back and look at prior year - you should be able to modify this based on the actual format you are using for the month.
Working on an SSAS Tabular project in Visual Studio 2010;
I'm trying to create a measure that calculates the total number of business days in a month:
I have Month Start Date and Month End Date measures, and Date and Is Business Day columns.
I can create a Total Business Days measure with COUNTROWS(FILTER(Dates,Dates[Is Business Day]=TRUE())). That gives me the number of business days in the context, but I want the number of business days for the current month.
I've tried various combinations of FILTER, COUNT, COUNTX, COUNTROWS, DATESBETWEEN, and CALCULATE without success.
What I want is a count of days between two dates, where the column [Is Business Day] is true, but I can't seem to get the right combination of filtering.
I would guess I filter the Dates table the way I do for the Total Business Days measure, but FILTER returns a table and COUNTROWS expects a single column - is there a way to get single column from a FILTER result?
Here's one thought...
First, create a calculated column called MonthKey (if you don't have it already):
=YEAR([Date]) * 100 + MONTH([Date])
Then create another calculated column called IsCurrentMonth
=IF(YEAR(TODAY()) * 100 + MONTH(TODAY()) = [MonthKey], 1, 0)
Then you can create your calculated measure as
COUNTROWS(FILTER(Dates,Dates[IsCurrentMonth] = 1))
Would that do what you need?
