Load Month, count(Sales) as NumberOfSalesPerMonth from abc.csv group
by Month;
Load Month, count(distinct Customer) as CustomerBuyingPerMonth from
abc.csv group by Month;
LoadMonth, count(*) as NumberOfRecordsPerMonth from abc.csv group per
Month;
NumericCount([ distinct ] expression )
Returns the numeric count of expression over a number of records as defined by a group by clause. If the
word distinct occurs before the expression, all duplicates will be disregarded.
Example:
Load Month, NumericCount(Item) as NumberOfNumericItems from abc.csv
group by Month;
TextCount([ distinct ] expression)
Returns the text count of expression over a number of records as defined by a group by clause. If the word
distinct occurs before the expression, all duplicates will be disregarded.
Example:
Load Month, TextCount(Item) as NumberOfTextItems from abc.csv group by
Month;
NullCount([ distinct ] expression )
Returns the NULL count of expression over a number of records as defined by a group by clause. If the
word distinct occurs before the expression, all duplicates will be disregarded.
Example:
Load Month, NullCount(Item) as NumberOfNullItems from abc.csv group by
Month;
MissingCount([ distinct ] expression )
Returns the missing count of expression over a number of records as defined by a group by clause. If the
word distinct occurs before the expression, all duplicates will be disregarded.
Example:
Load Month, MissingCount(Item) as NumberOfMissingItems from abc.csv
group by Month;
Advanced Aggregation
There is a special function for advanced aggregations:
aggr ([ distinct | nodistinct ] [{set_expression}]expression {,
dimension})
Returns a set of values of expression calculated over dimensions. The result can be compared to the expression
column of a 'local chart', evaluated in the context where the aggr function resides. Each dimension must
be a single field. It cannot be an expression (calculated dimension).
If the expression argument is preceded by the nodistinct qualifier, each combination of dimension values
may generate more than one return value, depending on underlying data structure. If the expression argument
is preceded by the distinct qualifier or if no qualifier is used at all, each combination of dimension values
will generate only one return value.
