Patent number: 10078570Abstract: A method for dynamically updating database statistics and a plurality of access paths associated with at least one database table is provided. The method may include identifying at least one dynamically changing column associated with the at least one database table. The method may further include determining at least one predicate pattern associated with the identified at least one dynamically changing column. Additionally, the method may include dynamically detecting at least one range change associated with the determined at least one predicate pattern based on at least one record insert. The method may also include updating the plurality of database statistics associated with the identified at least one dynamically changing column based on the dynamically detected at least one range change. The method may further include determining at least one filter factor based on the updated plurality of database statistics associated with the identified at least one dynamically changing column.Type: GrantFiled: May 26, 2016Date of Patent: September 18, 2018Assignee: International Business Machines CorporationInventors: Xiao Di Deng, Shuo Li, Shu Hua Liu, Wei Liu, Meng Wan, Xiaobo Wang, Xin Ying Yang, Chen Xin Yu, Xiong Wei Zhao
