| Abstract: | Query efficiency has long been a key factor in measuring database performance.With the rapid increase of the total amount of data in the network environment,the response time of database query is required more strictly.Aiming at the popular open source MySQL database,this paper analyzes the implementation process of executing SQL query,and obtains the objective factors affecting the query execution efficiency.On this basis,several practical and feasible performance optimization methods are put forward to ensure the correctness and efficiency of executing SQL statement. |
