Plsql query to list cases that have failed to create listing records

Question

i would like to create a query as follows
Give me all docket_num (whose batch_id's are =11051) from Import_case table
which do not have listing records on Listing_Table (either they don't exist at all
or if the do; the create_date in the Listing table is null OR cretae_date on Lsting table not = record_process_date on Import_case table.
-------- x ---------------
Import_case Table
==============
1. import_case_id number(38) primary key
2. batch_id number
3. record_processed_date date
4. docket_num varchar2(17)
case_master Table
=================
1. case_master_id number(38) primary key
2. docket_num varchar2(17)
Listing Table
==========
1. Listing_id number(38) primary key
2. case_master_id number(38)
3. created_date timestamp(6)
note: case_master table is a link between Import_case Table and Listing table
where docket_num on import_case table = docket_num on case_master
and case_master_id on case_master = case_master_id on Listing Table
Please reply at your earliest. Thanking you. Arvind Modi.

I have used following query, which gives me list of docket numbers on Import case Table; which don't have Listing records on Listing Table.
========================================================
select
ic.import_case_id as "IMP_CASE_ID",
ic.batch_id as "B_ID",
ic.docket_num as "DOCKET#",
ic.insert_timestamp as "INS_DT",
ic.record_processed_timestamp as "REC_PROCESS_DT",
ic.next_date as "NEXT DT"
from daoimp.import_case ic
-- ** insert Batch id ** >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
where ic.batch_id=11051
-- ** insert Batch id ** <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
minus
select
t.import_case_id as "IMP_CASE_ID",
t.batch_id as "B_ID",
t.docket_num as "DOCKET#",
t.insert_timestamp as "INS_DT",
t.record_processed_timestamp as "REC_PROCESS_DT",
t.next_date as "NEXT DT"
from daoimp.import_case t,
case_master cm,
listing l
-- ** insert Batch id ** >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
where t.batch_id=11051
-- ** insert Batch id ** <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
and
t.docket_num = cm.docket_num
and
cm.case_master_id = l.case_master_id
==================================================
The above query gives correct docket_numbers on Import_case table, but it also needs to include Docket numbers on Import_case Table
whose Listing records in Listing table contain NULL value in created_date
OR create_date on Listing table not equal record_process_date on Import_case Table.

Here is the actual request and above is my interpretation of it.
The goal of the task here is to create a tool. The tool can be run to check for missing listing records that were not created during the import process. When run, the tools returns a result set of records (docket_numbers) from the import case table that although processed on a particular date i.e., (record_process_date) do not have a matching listing record i.e., ( a listing record with a create_date equal to the record_process_date).
The ONLY VARIABLE PARAMETER NEEDED in this tool is the Batch ID for the import case table.

I am working on some other queries using inner join or outer join or not exists, but no success so far.
Please call me at my phone number or reply on my e-mail, if you like; so that I can clarify any issues.
