AX 2012 分组依据 table

Question

如何按具有特定字段的公共 table 进行分组？

我在 (dt.fieldname2Id('BatchNo'))

上遇到语法错误

这是我的代码：

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(int642str(Common.Recid));
}

Answer 1

您可以使用 Query 代替：

Common                  common;
SysDictTable            dt;
Query                   query = new Query();
QueryBuildDataSource    qbds; 
QueryRun                queryRun;

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

qbds = query.addDataSource(common.TableId);
qbds.addGroupByField(dt.fieldname2Id('CustAccount'));

queryRun = new QueryRun(query);

while (queryRun.next())
{
    ...
}
