X++ select group by date

(0) ShareShare

Posted on by Community Member

Hi,

It seems a stupid question but I tried multiple combination and failed.

In table A, I have thousands of records and I want to get all the different dates in this record.

In SQL, I know I can do it simply by

select date from TableA group by date

But now for X++ in AX

I tried

while select   A group by A.Date
{

}

without success. In MS doc, the examples are for number or counting no dates. I don't quite understand how to achieve my requirement.  Any help is grateful! Thanks!

    group by

    Instructs the database to group selected records by fields.

    CustTable custTable;

    ;

    while select sum(CreditMax) from custTable

        group by CustGroup

    {

        print custTable.CustGroup, " ",custTable.CreditMax;

    }

    You could do a count(RecId) to see how many records you have for the specific date instead of the sum() aggregate function in the example, and use the date for your grouping.

    It would help if you actually explained your problem. Saying "without success" doesn't tell us too much.
