Table schema:
CREATE TABLE Services (Service_Type_Code VARCHAR, Product_Price INTEGER); CREATE TABLE Ref_Service_Types (Service_Type_Description VARCHAR, Service_Type_Code VARCHAR)

Question: What are the descriptions of the service types with product price above 100?
SQL: SELECT T1.Service_Type_Description FROM Ref_Service_Types AS T1 JOIN Services AS T2 ON T1.Service_Type_Code = T2.Service_Type_Code WHERE T2.Product_Price > 100
