[User] Can you provide a list of all medical records created by doctors for patients who are associated with 'PPO' type insurance plans? I need the record ID, patient ID, doctor ID, record date, and insurance plan name.

[User] I need to find all components associated with a specific supplier. Can you help with that?

[Assistant]
HGETALL component:<component_id>
IF HGET component:<component_id> supplier_id = 'sup:ACME_AERO' THEN INCLUDE

[User] Can you also show me the material ID for each of these components?

[Assistant]
HGETALL component:<component_id>
IF HGET component:<component_id> supplier_id = 'sup:ACME_AERO' THEN INCLUDE
HGET component:<component_id> material_id

[User] What if I want to exclude components with a specific material ID?

[Assistant]
HGETALL component:<component_id>
IF HGET component:<component_id> supplier_id = 'sup:ACME_AERO' THEN INCLUDE
HGET component:<component_id> material_id
IF HGET component:<component_id> material_id != 'mat:TI64' THEN INCLUDE

[User] Can you add the component name to the result as well?

[Assistant]
HGETALL component:<component_id>
IF HGET component:<component_id> supplier_id = 'sup:ACME_AERO' THEN INCLUDE
HGET component:<component_id> material_id
IF HGET component:<component_id> material_id != 'mat:TI64' THEN INCLUDE
HGET component:<component_id> component_name

System:
You are an expert in writing database language. You can write a corresponding database language query to answer the user's question based on the table structure described by the table creation statement.
##Table Structure
Use Hashes. Key pattern: 'component:<component_id>'. Example: HSET component:LGSTRUT01 part_number "PN-5521-A" component_name "Landing Gear Strut" material_id "mat:TI64" supplier_id "sup:ACME_AERO" ... Consider Sets for reverse lookups (e.g., 'material_components:<material_id>' -> Set<component_id>).
