Abstract
A method is provided to process a hierarchical query request for requesting to query a target database table, where the hierarchical query request includes a query start condition and a connection condition. The method includes: in a first query round, first data is queried from the target database table based on the query start condition, and the first data is used as a root node of a tree structure; a plurality of pieces of service data in the target database table are grouped into N data groups corresponding to N worker threads based on the connection condition, where N is an integer greater than 1; and in an ith query round greater than 1, a leaf node in the current tree structure is selected as a parent node; and a target worker thread corresponding to the parent node is determined from the N worker threads based on the connection condition.
