如何总计SQL结果

Question

如何将我的结果总计为一条记录而不是item_id的多个实例。相反，我需要为每件商品开具总数量的发票。

select 
inv_mast.default_product_group, 
inv_mast.item_id, 
inv_mast.item_desc,oe_hdr.order_date, 
oe_line.qty_invoiced, 
oe_line.extended_price 

from 
job_price_hdr 

join oe_hdr on oe_hdr.job_price_hdr_uid = job_price_hdr.job_price_hdr_uid 
join oe_line on oe_line.order_no = oe_hdr.order_no 
join inv_mast on inv_mast.inv_mast_uid = oe_line.inv_mast_uid 

where 
oe_line.qty_invoiced> 0 
and 
oe_hdr.customer_id = 100080 
and 
default_product_group = 'FAST' 

order by 
inv_mast.item_id 

Answer 1

试试这个，让我知道如果你需要更多的信息

select 
    inv_mast.item_id,SUM(oe_line.qty_invoiced) 
    from 
    job_price_hdr 

    join oe_hdr on oe_hdr.job_price_hdr_uid = job_price_hdr.job_price_hdr_uid 
    join oe_line on oe_line.order_no = oe_hdr.order_no 
    join inv_mast on inv_mast.inv_mast_uid = oe_line.inv_mast_uid 

    where 
    oe_line.qty_invoiced> 0 
    and 
    oe_hdr.customer_id = 100080 
    and 
    default_product_group = 'FAST' 
    GROUP BY inv_mast.item_id 
    order by 
    inv_mast.item_id
