Abstract: Provided are a method and apparatus for processing an approximate query based on a machine learning model. When receiving a user query through an approximate query language extension interface, a processing apparatus parses a user query. The user query is an extended query form that includes information according to a user requirements. The processing apparatus generates a basic execution plan based on a parsing result and generates a plurality of executable candidate execution plans based on the basic execution plan. Then, an optimal final execution plan reflecting user requirements is selected from among the plurality of executable candidate execution plans, and query processing is performed on the user query based on a final execution plan.
