Problems solved by technology

At present, the inquiry about the abnormal data of marketing archives mainly relies on the online inspection module of the marketing system developed by each provincial company. The inspection rules involved in it may not meet the individual business needs of some regions, and may be Changes lead to the failure to update the audit rules in the provincial marketing system in time, resulting in too many abnormal data queries, which increases the workload of data query and reduces the audit work efficiency of the power supply bureau

Abstract

The embodiment of the invention discloses a data query method and device, equipment and a medium. The method comprises the steps of obtaining a target query formula input by a user, and determining at least one query object and an associated query condition in the target query formula, obtaining at least one original query data table matched with the query object, and searching whether an associated data table meeting the associated query condition with each original query data table exists in a data table association relationship knowledge base, according to the search result, generating at least one data table association structure pair, and querying in the data table structure knowledge base to obtain a joint query field corresponding to each data table association structure pair, and according to each joint query field, generating a target query rule corresponding to the target query formula, and querying to obtain query result data matched with the target query rule. According to the technical scheme, the personalized data query rule is formulated, and the data query efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of databases, and in particular, to a data query method, device, equipment, and medium. Background technique [0002] With the continuous development of power grid construction, more and more application systems are included in the power grid, and the data related to power distribution and consumption generated in the operation of various systems has also grown exponentially. [0003] The power supply service center is the supervisory organization of marketing business and service quality, responsible for checking the business handling of the marketing system and on-site service. At present, the inquiry about the abnormal data of marketing archives mainly relies on the online inspection module of the marketing system developed by each provincial company. The inspection rules involved in it may not meet the individual business needs of some regions, and may be As a result of the cha...
