Hmmm. Can you please give me the claimed amount for this customer
SELECT t1.amount_claimed FROM claim_headers AS t1 JOIN policies AS t2 ON t1.policy_id   =   t2.policy_id JOIN customers AS t3 ON t2.customer_id   =   t3.customer_id WHERE t1.amount_piad   =    ( SELECT max ( amount_piad )  FROM claim_headers ) 
claimed amount for this customer refers to t1.amount_claimed; need to join tables claim_headers, policies, and customers to access customer-related claim information; the amount for the maximum paid claim refers to max(amount_paid);
