    I have an issue about using dbr.calc with Col.sum reference.

    select 'dbr.dbr', 'Header';
    select 'dbr.sum', 'Value'; select 'dbr.calc', 'percent', '[Value]/[Value.sum]*100'; select Header, Name, Value as '[Value]', null as 'percent' from Table order by Header;

    This will divide each item with Total Value in the report, that's not what I want. I want the ratio in each Header group.

    How can I do it?

    The Value.sum refers to the full sum. What you can do is to it in a query:

    select 'dbr.hdr', 'Header';
    select 'dbr.sum', 'Value';
    select 'dbr.max', 'svalue'; select t.Header, t.Name, t.Value, t.percent, s.svalue
    from Table t
    join (
    select Header, sum(Value) as 'svalue'
    from Table
    group by Header
    ) s on s.Header=t.Header;

    Nice, but the Table is not static, it's temporary table so I can not re-use (in mysql). So I must re-call all Select code. But I'll take this solution for now.

    If you have the data in a temporary table, MySQL does not allow to refer the same table more than once in the same query. Instead of re-calling the original select code, you can run the aggregate query into another temporaty table. Will be much faster and easier.

    There has not been a new command to handle the hdr sum situation spyhunter88 mentioned above, has there?

    No, the solution would still be the same.
