Regarding to find out data bug..

Question

Hi guys
I have 3 table a, b,and c
in which b is a tale where i have r_id, c_number and error_msg
table a has ar_id, r_id, a_id and other column but these three are imp.
relationship between a and b is r_id is (p.k) of table b is f.k to to table a
and ar_id is table a 's primary key which is unique
now i have table c which is bulk table it has relation ship with from table a ar_id is fk to table c and due to table c is bulk a_id also exists in table c which is
has partition
and table c has other column just like t_name, r_value..
so what i have to validate is
take data from table a which exist in table b based on the r_id (which mapped)to a
pullout the ar_id,r_id,and a_id from table a then
look for table c with this information. is it properly mapped from table a to c basis on the ar_id and partitions column if not properly mapped ar_id with table a the n flag message in table b saying that particular value not set properly.
f value exist in table c wr.t a then check
validate t_valye, r_value column if they are null or not if null also set message in table b saying that this column are null so not properly mapped.
as table c is huge it should not scan more than once it will hamper the performance..
help appreciated....
Thanks
