PU_PRODUCT
Description

Calculates the product of the specified source column for each element in the given target table.

Like the regular PRODUCT 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.

Syntax
 PU_PRODUCT ( target_table, source_table.column [, filter_expression] )
  • target_table: The table to which the aggregation result should be pulled. This can be:

  • source_table.column: The column which should be aggregated for every row of the target_table.

  • filter_expression (optional): An optional filter expression to specify which values of the source_table.column should be taken into account for the aggregation.

NULL handling

If no value in the source table column exists for the element in the target table (either because all values of the source table are filtered out, or because no corresponding value exists in the first place), NULL will be returned. NULL values in the source table column are treated as if the row does not exist.

Examples

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

Query

Column1

         "companyDetail"."companyCode"
        

Column2

         PU_PRODUCT ( "companyDetail" , "caseTable"."value" )

PU-functions can be used in a FILTER. In this example, the company codes are filtered such that the corresponding product of case table values is smaller than 100000:

Query

Filter

         FILTER PU_PRODUCT ( "companyDetail" , "caseTable"."value" ) < 100000;
        

Column1

         "companyDetail"."companyCode"
        

Input

Output

caseId : int

companyCode : string

value : int

PU-functions can be used inside another aggregation function. In this example, the maximum value of all accumulated case table values for each company code is calculated:

Query

Column1

         MAX ( PU_PRODUCT ( "companyDetail" , "caseTable"."value" ) )
        

Input

Output

caseTable

caseId : int

companyCode : string

Calculate the product of the case table values for each company code. Only consider cases with an ID larger than 2:

Query

Column1

         "companyDetail"."companyCode"
        

Column2

         PU_PRODUCT ( "companyDetail" , "caseTable"."value" , "caseTable"."caseID" > 2 )

Calculate the product of the case table values for each company code. Only consider cases with an ID larger than 3. All case table values for companyCode '001' are filtered out, which means that in this case, NULL is returned.

Query

Column1

         "companyDetail"."companyCode"
        

Column2

         PU_PRODUCT ( "companyDetail" , "caseTable"."value" , "caseTable"."caseID" > 3 )

Example over three tables: For each entry in table B, calculate the product 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

         "B"."B_KEY"
        

Column2

         PU_PRODUCT ( "B" , "C"."VALUE" , "C"."VALUE" > 100 )
