Description

Calculates the sum of the specified column for each element of the given child 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 parent table exists for the element in the child table (either because all values of the parent table column are filtered out, or because no corresponding value exists in the first place), NULL will be returned.

Syntax

PU_SUM ( child_table, parent_table.column [, filter_expression] )
PU_SUM ( DOMAIN_TABLE ( column1,...,columnN ), parent_table.column [, filter_expression] )

Examples


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

Query
Column1
"companyDetail"."companyCode"
Column2
PU_SUM("companyDetail", "caseTable"."value")
Input
caseTable
caseId : INTcompanyCode : STRINGvalue : INT
1
'001'
600
2
'001'
400
3
'001'
200
4
'002'
300
5
'002'
300
6
'003'
200
companyDetail
companyCode : STRINGcountry : STRING
'001''DE'
'002''DE'
'003''US'

Foreign Keys

Output
Result
Column1 : STRINGColumn2 : INT
'001'
1200
'002'
600
'003'
200



[2] PU functions can be used in a FILTER. In this example, the company codes are filtered such that the corresponding sum of case table values is smaller than 800:

Query
Filter
FILTER PU_SUM ( "companyDetail", "caseTable"."value" ) < 800
Column1
"companyDetail"."companyCode"
Input
caseTable
caseId : INTcompanyCode : STRINGvalue : INT
1
'001'
600
2
'001'
400
3
'001'
200
4
'002'
300
5
'002'
300
6
'003'
200
companyDetail
companyCode : STRINGcountry : STRING
'001''DE'
'002''DE'
'003''US'

Foreign Keys
caseTable.companyCodecompanyDetail.companyCode
Output
Result
Column1 : STRING
'002'
'003'



[3] 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_SUM ( "companyDetail", "caseTable"."value" ) )
Input
caseTable
caseId : INTcompanyCode : STRINGvalue : INT
1
'001'
600
2

400
3
'001'
200
4
'002'

5
'002'
300
6
'003'
200
companyDetail
companyCode : STRINGcountry : STRING
'001''DE'
'002''DE'
'003''US'

Foreign Keys
caseTable.companyCodecompanyDetail.companyCode
Output
Result
Column1 : INT
1200



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

Query
Column1
"companyDetail"."companyCode"
Column2
PU_SUM("companyDetail", "caseTable"."value", "caseTable"."caseID" > 2)
Input
caseTable
caseId : INTcompanyCode : STRINGvalue : INT
1
'001'
600
2
'001'
400
3
'001'

companyDetail
companyCode : STRINGcountry : STRING
'001''DE'
'002''DE'
'003''US'

Foreign Keys

Output
Result
Column1 : STRINGColumn2 : INT
'001'
200
'002'
600
'003'
200



[5] Calculate the sum 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_SUM("companyDetail", "caseTable"."value", "caseTable"."caseID" > 3)
Input
caseTable

[6] 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
"B"."B_KEY"
Column2
PU_SUM("B", "C"."VALUE", "C"."VALUE" >100)
Input
A
B_KEY : INTC_KEY : STRINGVALUE : INT

[7] For each case ID, calculate the sum of the case table values for the associated company code using DOMAIN_TABLE:

Query
Column1
