Sum based on Number values in a Char string..

Question

i have a requirement
i have a field on my form, designed in form6i (oracle 10g)
my tables are;
with t1 as (
            select 101 t1_code,'it101' t1_itcode, 10 t1_qty, 5.5 t1_prc from dual union all
            select 101,'it102',  5 , 3 from dual union all
            select 102,'it102', 10 , 3 from dual union all
            select 102,'it104', 10 , 5 from dual union all
            select 103,'it101', 10 , 5.5 from dual)
select * from t1;
with t2h as (
            select 11 t2h_no, 101 t2h_code from dual union all
            select 12 , 101  from dual union all
            select 13 , 102  from dual union all
            select 14 , 103  from dual )
select * from t2h;
with t2d as (
            select 11 t2d_no, 'it101' t2d_itcode, 5 t2d_qty from dual union all
            select 11 , 'it102', 5 from dual union all
            select 12 , 'it101', 5 from dual union all
            select 13 , 'it102', 5 from dual union all
            select 13 , 'it104', 5 from dual union all
            select 13 , 'it102', 5 from dual union all
            select 13 , 'it104', 5 from dual union all
            select 14 , 'it101', 10 from dual)
select * from t2d;t1_CODE , t2h_no and t2d_no are fields Number datatype.
var m_x varchar2(20);
exec :m_x :='11,12';
lets say the value of m_x (t2d_no) is 11,12
i want the query to sum t2d_qty for t2d_no 11 & 12 and put 1 t1_prc in the resultant row
based on the matching t1_itcode with t2d_itcode
the result should be like this for m_x = 11,12
T1_IT        T1_QTY        T1_PRC
it101        15.000         5.500
it102         5.000         3.000
if m_x hold just 11 then it should return just;
T1_IT        T1_QTY        T1_PRC
it101         5.000         5.500
it102         5.000         3.000if m_x hold just 11,13 then it should return an error msg
as the t2h_code is not the same for t2d_no 11 & 13;
kindly suggest..
TY

Answer 1

I tried to solve the puzzle. But I'm already confused on the requirement. On what fields do you want to join and what fields to sum....??
I did this, but then I got lost.... maybe you can use it as a start to define "join" and "sum" ... conditions.
with t1 as (
            select 101 t1_code,'it101' t1_itcode, 10 t1_qty, 5.5 t1_prc from dual union all
            select 101,'it102',  5 , 3 from dual union all
            select 102,'it102', 10 , 3 from dual union all
            select 102,'it104', 10 , 5 from dual union all
            select 103,'it101', 10 , 5.5 from dual),
t2h as (
            select 11 t2h_no, 101 t2h_code from dual union all
            select 12 , 101  from dual union all
            select 13 , 102  from dual union all
            select 14 , 103  from dual ),
t2d as (
            select 11 t2d_no, 'it101' t2d_itcode, 5 t2d_qty from dual union all
            select 11 , 'it102', 5 from dual union all
            select 12 , 'it101', 5 from dual union all
            select 13 , 'it102', 5 from dual union all
            select 13 , 'it104', 5 from dual union all
            select 13 , 'it102', 5 from dual union all
            select 13 , 'it104', 5 from dual union all
            select 14 , 'it101', 10 from dual)
select t1.t1_itcode,sum(a.t2d_qty)t2d_qty ,sum(t1.t1_prc)t1_prc
FROM
(select t2d.t2d_no,sum(t2d.t2d_qty) t2d_qty
from t2d
inner join t2h
on (t2d.t2d_no=t2h.t2h_no)
where t2d.t2d_no in (11,12)
group by t2d.t2d_no
) a
inner join t1
on (t1.t1_qty = a.t2d_qty )
group by t1.t1_itcode, t1.t1_prc;
