To find all the child records are processed before parent records

Question

Hi,
When i am trying to process consignment pulls and my client is using third party tool to insert the data into interface tables. My logic is written in such a way that it should pick parent record associated with child but there is some delay in child records and not all the child records are being pulled with parent.
In a brief, i need to write a condition in such a way that my parent cursor should pick all the child records with max(last_updated_date) and then it should be processed.
eg: I have a family and need to catch bus with all my family members. I need to check now for the last family member who get into and should wait for atleast 2mins so as to ensure all my family members are in. I am unable to achieve this with count. Please do revert back soon.
Details are below:
CURSOR c_pull (p_pull_id NUMBER) IS----------------------------------parent cursor
SELECT ecp.ROWID ROW_ID
,ecp.*
FROM consignment_pulls ecp
WHERE ecp.process_flag IN ( 2, 3 )
AND ecp.pull_id > NVL(p_pull_id,0)
ORDER BY ecp.pull_id
FOR UPDATE OF ECP.PROCESS_FLAG NOWAIT;
CURSOR c_line (p_pull_id NUMBER) IS----------------------------------child cursor
SELECT ecpi.ROWID ROW_ID
,ecpi.*
FROM consignment_pull_items ecpi
WHERE ecpi.process_flag IN ( 2, 3 )
AND ecpi.pull_id = p_pull_id
FOR UPDATE OF ecpi.process_flag;

Answer 1

Hi Helios,
Thanks for the info. But its not a concurrent request something like we can filter with start date and completion date. Its all about selection of records from headers and lines table and not able to make those selection of header records with a delay of say some 2minutes until all the child records are inserted.
Thanks,
