Question

我是SQL新手。我正在尝试编写一个与forcast-fulfillment-sql-query几乎相似的查询，但我的业务需要是根据req_qty上运行的max_qty来reserve_qty STORE_ID_B }

表格：1

STORE_ID_A  req_qty max_qty shop_rnk
1002            3       5   1
1003            5       8   2
1004            1       5   3
1005            3       5   5
1006            3       5   6
1007            3       5   8
1008            3       5   9
1009            3       5   10
1010            2       5   11
1011            3       5   12
1012            2       5   13

表2：

STORE_ID_B       reserve_qty    rnk
    500             10          1
    501             9           2

预期输出：

STORE_ID_A  STORE_ID_B  release_qty
1002            500         3
1003            500         7
1004            501         1
1005            501         3
1006            501         5

对于第一行STORE_ID_B reserve_qty = 10和STORE_ID_A req_qty 3和max_qty 5.。10不在3和5之间，所以我需要取req_qty即3。第二行，现在余额reserve_qty是（10-3）= 7，它位于5到8之间，所以我需要max_qty。发送数量将基于Store_ID_A和STORE_ID_B等级。

到目前为止，我已尝试过以下。但没有得到所需的输出。任何帮助都将受到高度赞赏。

WITH  t1 AS (
  select t1.*,
         coalesce(sum( reserve_qty ) over ( order by rnk range between unbounded preceding and 1 preceding),0) As range_start,
         sum( reserve_qty ) over ( order by rnk ) As range_end
  from table1 t1
),
t2 As (
    select t2.*,
           coalesce(sum( req_qty ) over ( order by shop_rnk range between unbounded preceding and 1 preceding),0) As range_start,
           sum( req_qty ) over ( order by shop_rnk ) As range_end
    from table2 t2
)


    select t1.*,t2.* , t1.req_qty - coalesce(sum(er_rtl_dm..least( from_loc_rec.range_end, to_loc_rec.range_end ) - greatest( from_loc_rec.range_start, to_loc_rec.range_start )) OVER (
                               PARTITION BY from_loc_rec.vpn,from_loc_rec.color,from_loc_rec.loc_CD ORDER BY to_loc_rec.rnk rows BETWEEN unbounded preceding
                                             AND 1 preceding
                               ), 0) 
    FROM t1
    join t2
    on not ( t1.range_end <= t2.range_start OR t1.range_start >= t2.range_end)

范围sql查询
