DATABASE INDEX AND DATABASE QUERY PROCESSING METHOD, APPARATUS, AND DEVICE

Abstract:

A method including determining a database table for which a database index is to be created, wherein the database table comprises a spatial field for storing spatial data; acquiring, for the database table, a spatial filter condition comprising a spatial field ID; and generating, according to the spatial filter condition, a tree-structured spatial index for the database table, wherein a leaf node of the tree-structured spatial index stores therein spatial data meeting the spatial filter condition and its primary key ID. The efficiency of queries related to spatial data is thus enhanced.
