Hi All,
I have a table as below
table name = table
columns are as below :
id(Unique num)
subtyp_cd ('ORIG', 'RESUM')
state
quarter
contract
prod_num
clm_num
And here are the records -
id= 111, Clm_num=12, subtyp_cd = ORIG, state=CA, Contract = C1,
Quarter=01/01/2000, prod = p1
id= 112, Clm_num=12, subtyp_cd = ORIG, state=CA, Contract = C1,
Quarter=01/01/2000, prod = p2
id= 113, Clm_num=12, subtyp_cd = ORIG, state=CA, Contract = C1,
Quarter=01/01/2000, prod = p3
id= 114, Clm_num=13, subtyp_cd = RESUM, state=CA, Contract = C1,
Quarter=01/01/2000, prods = p2
id= 115, Clm_num=13, subtyp_cd = RESUM, state=CA, Contract = C1,
Quarter=01/01/2000, prod = p2
id= 116, Clm_num=10, subtyp_cd = ORIG, state=IL, Contract = C1,
Quarter=01/01/2000, prod = p11
id= 117, Clm_num=10, subtyp_cd = ORIG, state=IL, Contract = C1,
Quarter=01/01/2000, prod = p12
id= 118, Clm_num=10, subtyp_cd = ORIG, state=IL, Contract = C1,
Quarter=01/01/2000, prod = p13
id= 119, Clm_num=11, subtyp_cd = RESUM, state=CA, Contract = C1,
Quarter=01/01/2000, prod = p14
I need to pull the prod_num that is in subtyp_cd = 'RESUM' and not in
subtyp_cd = 'ORIG'
from the example above, need to pull clm_num = 11 and prod_num p14
its a self joined query -
this is how it is joined:
select b.id, b.prod_num
from table a, table b
where a.contract = b.contract
and a.state = b.state
and a.quarter = b.quarter
and a.clm_num <> b.clm_num
and a.subtyp_cd = 'ORIG'
and b.subtyp_cd = 'RESUB'
and b.prod_num not in (select prod_num from table where clm_num = a.clm_num)
this query is not returning the expected results. I get multiple records,
please let me know what am i missing?
Thanks in advance!
