下面是ls_SQLSTRING变量内容，如何在 select 处和 group by 后面都添加 "inv_back_view.list_no"，位置只要在SELECT 后面和GROUP BY 后面任何位置添加都可以，如何实现？
SELECT inv_back_view.cli_no,
client_view.cli_name,
client_view.client_Type_Name,
client_view.dis_Name,
sum(inv_back_view.inv_num * inv_back_view.sell_price) as inv_mon,
sum(inv_back_view.back_num * inv_back_view.sell_price) as back_mon,
sum(inv_back_view.inv_num * inv_back_view.dep_price) as inv_dep_mon,
sum(inv_back_view.back_num * inv_back_view.dep_price) as back_dep_mon,
sum(inv_back_view.inv_num * inv_back_view.std_price) as std_mon,
sum(inv_back_view.back_num * inv_back_view.std_price) as std_back_mon,
sum(inv_back_view.inv_num * inv_back_view.retail_price) as retail_mon,
sum(inv_back_view.back_num * inv_back_view.retail_price) as retail_back_mon
FROM inv_back_view,
client_view
WHERE ( inv_back_view.cli_no = client_view.cli_no )
group by inv_back_view.cli_no,
client_view.cli_name,
client_view.client_Type_Name,
client_view.dis_Name"
更改后变成
SELECT inv_back_view.cli_no,
inv_back_view.list_no,
client_view.cli_name,
client_view.client_Type_Name,
client_view.dis_Name,
sum(inv_back_view.inv_num * inv_back_view.sell_price) as inv_mon,
sum(inv_back_view.back_num * inv_back_view.sell_price) as back_mon,
sum(inv_back_view.inv_num * inv_back_view.dep_price) as inv_dep_mon,
sum(inv_back_view.back_num * inv_back_view.dep_price) as back_dep_mon,
sum(inv_back_view.inv_num * inv_back_view.std_price) as std_mon,
sum(inv_back_view.back_num * inv_back_view.std_price) as std_back_mon,
sum(inv_back_view.inv_num * inv_back_view.retail_price) as retail_mon,
sum(inv_back_view.back_num * inv_back_view.retail_price) as retail_back_mon
FROM inv_back_view,
client_view
WHERE ( inv_back_view.cli_no = client_view.cli_no )
group by inv_back_view.cli_no,
inv_back_view.list_no,
client_view.cli_name,
client_view.client_Type_Name,
client_view.dis_Name"
