Abstract
This specification discloses data query methods and apparatuses, storage media, and electronic devices. In an example method, a query statement input by a user is obtained, where the query statement is used to query data from a database. Based on the query statement, an execution plan corresponding to the query statement is generated. Based on the execution plan, each query operation involved in the execution plan and an execution order of query operations are; determined. A target operation from the query operations is determined based on the execution order of the query operations, where the target operation is an operation other than a last query operation to be executed among the query operations. When executing the execution plan, deduplication is performed on duplicate results included in query results obtained by executing the target operation. Based on deduplicated query results, query data corresponding to the query statement is obtained.
