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||| 25

Canutility|AA|||15

Canutility|CC| ||19

Divadip|CC|2|4|16

Divadip|DD|3|1|25

] (delimiter is '|');

MissCount1:

LOAD Customer,MissingCount(OrderNumber) as MissingOrdersByCustomer Resident Temp Group By Customer;

 

Load MissingCount(OrderNumber) as TotalMissingCount Resident Temp;

Customer MissingOrdersByCustomer

Astrida 0

Betacab 1

Canutility 2

Divadip 0

 

The second statement gives:

TotalMissingCount

3

in a table with that dimension.

Given that the Temp table is loaded as in the previous example:

LOAD MissingCount(distinct OrderNumber) as TotalMissingCountDistinct Resident Temp;

TotalMissingCountDistinct

1

Because there is only oneOrderNumber one missing value.
