We have a Table with K1, K2, K3, K4 as Primary keys with about 800 million
records. A child table, which is partitioned, has K1, K2, K3, K4, K5 (Seq
Number) as Primary keys and a Status field (value of A or I) with about 10
billion records. Child table having no record for the 4 keys is possible,
though highly unlikely.

I need to get a list of records (just the key fields) from the main Table,
which has no record in the child table with Status = 'A' (may or may not
have an 'I' Status record).

Can someone please help me with some efficient sql code to achieve this?
