Hello!  Can you provide me with a list of all customer ids and their associated policy type codes?
select t2.customer_id, t1.policy_type_code from policies as t1 join customers as t2 on t1.customer_id = t2.customer_id
Great!  Can you update this list to include the customer details values for each customer_ID?
select t2.customer_id, t1.policy_type_code, t2.customer_details from policies as t1 join customers as t2 on t1.customer_id = t2.customer_id
Awesome! Can you filter this list to show only the customer IDs  and customer names associated with either a deputy policy or an uninformed policy?
select t2.customer_id, t2.customer_details from policies as t1 join customers as t2 on t1.customer_id = t2.customer_id where t1.policy_type_code = "Deputy" or t1.policy_type_code = "Uniform"
