Number of Occurances

Tue, 30 Aug 2016 05:03:58 GMT

Hi All, I have a dataset of the customers to an F&B outlet at a hotel.

I would like to show the number of repeat guests to the restaurant each month so need to count the occurrences of each guest name and then show only those greater than 1 by month. Can anyone advise on the script for this?

In the bar chart I would just like to show each month the number of repeat guests which I will show as a percentage of total guests for the month.

Thanks for your help!

Hi Kaushik, thank you for your reply. Some data is attached here.

I would like to eliminate all guests with an occurrence of only 1 and to

sum (or count) the remaining.

e.g. if Paul has 3 occurrences, Russell and 2 Occurrences and Steve has 1

occurrence.

By 1st eliminating Steve who has only 1 occurrence the sum would be 5 and

the count would be 2.

Thanks for your help, really appreciated.

Russell

Hi Rusell,

With your data and this script, this will be your output:

Data:
LOAD Date, 
     MonthName(Date) as MonthName,
     RowNo()         as RowNum,
     Time, 
     BillNo, 
     Total, 
     [Guest Name]
FROM
[Data for Occurance Question.xlsx]
(ooxml, embedded labels, table is Sheet1);


Occurences:
LEFT JOIN (Data)
LOAD
    MonthName,
    COUNT(DISTINCT RowNum) as Occurrence,
    [Guest Name]
RESIDENT Data
GROUP BY MonthName, [Guest Name];

FinalData:
LOAD
    MonthName,
    COUNT(DISTINCT RowNum) as Times,
    COUNT(DISTINCT [Guest Name]) as Customers
RESIDENT Data
WHERE Occurrence > 1
GROUP BY MonthName;

Regards!!
