Data query method and device, electronic equipment and computer readable medium

Abstract

The invention discloses a data query method and device, electronic equipment and a computer readable medium, and relates to the technical field of computers.The specific implementation mode comprises the steps that a data query request is received, and an original query statement is obtained; responding to sensitive-related fields contained in the original query statement, and querying desensitization rules corresponding to the sensitive-related fields; splitting the original query statement to obtain split statements, and determining a target rewriting range based on the split statements and the target clauses; rewriting the original query statement based on the desensitization rule and the target rewriting range to obtain a target query statement; and in response to the condition that the original query statement does not have the corresponding sub-query statement, executing the target query statement to obtain query result data. Therefore, the efficiency and accuracy of desensitization data query in an ad-hoc query scene are improved.
