Description

Calculates the sum of the specified column for each element of the given parent table.

Like the regular SUM operator, the column can either be an INT or FLOAT column. The data type of the result is the same as the input column data type.

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), NULL will be returned.

Syntax

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

Examples

Calculate the sum of the case table values for each company code:

Query

Example over three tables: For each entry in table B, calculate the sum of the values that are larger than 100 in table C. Tables B and C do not have a direct connection, but are connected via table A:

Query
Column1

Column2
PU_SUM("B", "C"."VALUE", "C"."VALUE" >100)
Input
