Summary:The invention discloses a business data query method and device, a storage medium, a processor and electronic equipment. The method comprises the steps of receiving a data query request sent by a client side, wherein the data query request is used for querying a service data table; performing grammar analysis processing on the data query request to obtain an initial query statement; determining an overhead matching rule and a statement rewriting rule corresponding to the initial query statement; rewriting the initial query statement based on the overhead matching rule and the statement rewriting rule to obtain a rewritten query statement; and obtaining the service data table and service data in the service data table from a target database based on the rewritten query statement. According to the invention, the technical problem of low service data query efficiency caused by continuous increase of service data volume and dramatic increase of scanning and association cost of the service data table is solved. 本发
