Count - script function

Count() returns the number of values aggregated in expression, as defined by a group by clause.

Syntax:  

Count( [ distinct ] expr)

Return data type: integer

Arguments:  

Argument Description
expr The expression or field containing the data to be measured.
distinct If the word distinct occurs before the expression, all duplicates are disregarded.

Examples and results:  

Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in our document to see the result.

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 TotalOrderNumber Resident Temp;

TotalOrderNumber

9

Because there are two values of OrderNumber with the same value, 1.
