How to group by with common table

How to group by a common table with a specific field?

I'm getting a syntax error on (dt.fieldname2Id('BatchNo'))

Here's my code:

Common          common;
SysDictTable    dt;

dt        =    SysDictTable::newName('Table1');
common    =    dt.makeRecord();

while select count(RecId) from common
    group by common.(dt.fieldname2Id('BatchNo'))  //syntax Error here
    where common.(dt.fieldname2Id('flag'))==1
{
    info(strFmt('%1',common.RecId));
}

    I'm not sure if anything like that is supported; I've never seen that. I would simply use the query framework (addGroupByField()).

    Thanks Martin, that worked. I have been trying all sorts of things with Common, trying to treat it like a normal buffer table object as I'm unable to find any good documentation on Common and other generic types. Please share if you have any handy.

    Here's the working code:

        Common                  common;
    Query                   query;
    QueryBuildDataSource    qbds;
    QueryRun                queryRun;
    int                     row=0;
    TableId                 TableId;

    query   = new Query();
    TableId = tableName2id(TableName);
    qbds = query.addDataSource(TableId);

    qbds.addGroupByField(fieldname2Id(TableId,'BatchNo'));
    qbds.addRange(fieldName2id(TableId,'Flag')).value('1');

    queryRun = new QueryRun(query);

    while (queryRun.next())
    {
        row++;
    }

    info(int2str(row));
