Description

Calculates the number of distinct elements in the specified column for each element of the given parent table.

PU_COUNT_DISTINCT can be applied on any data type. The data type of the result is always an INT.

If no value in the child table exists for the element in the parent table (either because all values of the child table column are filtered out, or because no corresponding value exists in the first place), 0 will be returned.

Syntax

PU_COUNT_DISTINCT ( parent_table, child_table.column [, filter_expression] )
