Question

我需要动态指定任何AOT查询，然后回读列和值。

我非常接近。唯一的问题是它列出了每个数据源中的所有字段，而不仅仅是指定的字段，以便在查询中返回值。

有什么建议我如何才能返回查询结果字段，而不是返回数据源中的所有列？

谢谢，

布拉德

        while (queryRun.next())
        {
            //parse through each datasource
            for(i = 1; i <= workingQuery.dataSourceCount(); i++)
            {
                //get all fields in this data source
                qbfl = workingQuery.dataSourceNo(i).fields();
                cnt = qbfl.fieldCount();  //this comes up with the correct number, so AX is aware of the right number

                //DID NOT WORK EITHER common = workingQuery.dataSourceNo(i).getNo();
                common = queryRun.get(workingQuery.dataSourceNo(i).table());
                dicttable = new DictTable(common.TableId);
                fieldcnt   = dicttable.fieldCnt();
                //parse through the fields and set the values in the new table
                for (i = 1; i <= fieldcnt; i++)
                {
                    //write the field names and values
                    fieldid   = dicttable.fieldCnt2Id(i);
                    dictfield = new dictfield(common.TableId,fieldid);
                    info(dicttable.fieldName(fieldid));
                    info(common.(dictfield.id()));                            
                }
            }
        }

您需要使用fieldCount和field方法迭代系统类QueryBuildFieldList。另请查看Axaptapedia。

Query q = new Query(queryStr(CustTable));
QueryBuildDataSource qbds = q.dataSourceTable(tableNum(CustTable));
QueryBuildFieldList qbfl = qbds.fields();
Counter i;
for (i = 1; i <= qbfl.fieldCount(); i++)
    info(new DictField(qbds.table(), qbfl.field(i)).name());
