Examples and results:
Add the example script to your app and run it. Then add, at least, the fields listed in the results column to a sheet in our app to see the result.
To get the same look as in the result column below, in the properties panel, under Sorting, switch from Auto to Custom, then deselect numerical and alphabetical sorting.
| Example | Result |
|---|---|
|
Temp: LOAD * inline [ Customer|Product|OrderNumber|UnitSales|UnitPrice Astrida|AA|1|4|16 Astrida|AA|7|10|15 Astrida|BB|4|9|9 Betacab|CC|6|5|10 Betacab|AA|5|2|20 Betacab|BB|1|25| 25 Canutility|AA|3|8|15 Canutility|CC|||19 Divadip|CC|2|4|16 Divadip|DD|3|1|25 ] (delimiter is '|');
Count1: LOAD Customer,Count(OrderNumber) as OrdersByCustomer Resident Temp Group By Customer; |
Customer OrdersByCustomer Astrida 3 Betacab 3 Canutility 2 Divadip 2 As long as the dimension Customer is included in the table on the sheet, otherwise the result for OrdersByCustomer is 3, 2. |
|
Given that the Temp table is loaded as in the previous example: |
TotalOrderNumber 10 |
|
Given that the Temp table is loaded as in the first example: LOAD Count(distinct OrderNumber) as TotalOrdersNumber Resident Temp; |
TotalOrderNumber 9 Because there are two values of OrderNumber with the same value, 1. |
