[User] Can you help me fetch the inventory details for components associated with a specific aircraft build, including the batch number, quantity, and warehouse location?

[Assistant]
MATCH (ab:AircraftBuild {build_id: 'specific_build_id'})-[:IS_MODEL]->(am:AircraftModel),
(ib:InventoryBatch)-[:IS_INSTANCE_OF]->(c:Component)
RETURN ib.inventory_record_id, ib.batch_number, ib.quantity, ib.location_warehouse

[User] Can you modify this to show only inventory batches received after a specific date, say June 1, 2023?

[Assistant]
MATCH (ab:AircraftBuild {build_id: 'specific_build_id'})-[:IS_MODEL]->(am:AircraftModel),
(ib:InventoryBatch)-[:IS_INSTANCE_OF]->(c:Component)
WHERE ib.received_date > datetime('2023-06-01')
RETURN ib.inventory_record_id, ib.batch_number, ib.quantity, ib.location_warehouse

[User] What if I also want to exclude batches with quantities less than 10?

[Assistant]
MATCH (ab:AircraftBuild {build_id: 'specific_build_id'})-[:IS_MODEL]->(am:AircraftModel),
(ib:InventoryBatch)-[:IS_INSTANCE_OF]->(c:Component)
WHERE ib.received_date > datetime('2023-06-01') AND ib.quantity >= 10
RETURN ib.inventory_record_id, ib.batch_number, ib.quantity, ib.location_warehouse
