How to clear selection field of sum in a query in x++

(0) ShareShare

Posted on by Community Member

Hi all,

I have applied a group by and sum of in a form, modifying its data source execute query method.

maYearlySummaryDatasource.addGroupByField(fieldNum(maYearlyAffiliateTable,groupId));
maYearlySummaryDatasource.addSelectionField(fieldNum(maYearlyAffiliateTable,AmountCur),SelectionField::Sum);

based on a checkbox selection this group by and sum should be applied. I have written logic for that.

I want to clear the group by and sum of on unticking the check box.

I was able to clear the group by with 

this.query().clearGroupBy();

but unable to clear the (sum of) with 

this.query().clearHavingFilters(maYearlySummaryDatasource,fieldStr(maYearlyAffiliateTable,AmountCur));

Kindly suggest how to achieve this.

Thanks,

Praveen.

    Try fields().clearFieldList().

    HAVING is something else.

    Hi martin,

    The datasource().fields().clearFieldList(). is clearing all the fields except recid.

    the output shows un retrieved for all the fields.

    I have added the following lines in the code and I'm getting the proper output as expected.

           this.query().clearGroupBy();

           maYearlySummaryDatasource.fields().clearFieldList();

           maYearlySummaryDatasource.addAllFields(tableStr(maYearlyAffiliateTable));

    Here the this.query().clearGroupBy(); is neeeded becasue if removed its giving an sql error as 

     SELECT T1.GROUPID,T1.GROUPID FROM MAYEARLYAFFILIATETABLE T1 WHERE ((PARTITION=?) AND (DATAAREAID=?)) GROUP BY T1.GROUPID,T1.GROUPID ORDER BY T1.GROUPID,T1.GROUPID OPTION(FAST 20)

    A column has been specified more than once in the order by list. Columns in the order by list must be unique.


    Its selecting groupid twice.

    The requirement is completed now with your suggestion.

    Appreciate your help.

    Thank you,

    Praveen.

    Yes, clearFieldList() clears the whole field list, i.e. all fields.
