This paper is based on the perspective of query optimization of SQL statements.After research and comparative analysis on the current methods for dynamic multi-conditional query in the development of database applications,a more efficient and general method for dynamic multi-conditional query is proposed.In this method,ingenious improvements have been made on the basis of current methods for dynamic multi-conditional query and the efficiency has been greatly increased.Concise and flexible SQL statements and code will be formed when adopting this method.It is suitable for the design of general query modules and the development of efficient search engine.
