Abstract

The invention discloses an inquiry method, device and apparatus for an electroinc device, and a storage medium. The method comprises the following steps of: acquiring a query request of an electronicinvoice, wherein the query request comprises data to be queried, data attributes and data attribute relationships; obtaining an invoice identification list, wherein the invoice identification is obtained from an invoice index table according to the data to be queried, and the attributes of the invoice identification list are the same as the data attributes; obtaining an electronic invoice identification set, wherein the electronic invoice identification set is a screening result of an invoice identification list according to a data attribute relationship; and obtaining the electronic invoice data corresponding to the electronic invoice identifier in the set of electronic invoice identifiers. The invention solves the problem that the query efficiency of the electronic invoice data is low due to the fact that the relational database is adopted in the prior art for storing and managing the billions-level invoice data, achieves that the electronic invoice data can be obtained without scanning the whole table of the electronic invoice data table, thereby improving the technical effect of the query efficiency of the electronic invoice data.

Description

technical field [0001] The embodiments of the present invention relate to data processing technology, and in particular, to an electronic invoice query method, device, equipment and storage medium. Background technique [0002] With the development of the information industry, the application of electronic invoices is becoming more and more extensive. Electronic invoices are the same as ordinary invoices, and they are also distributed to merchants in the form of uniform issuance by the tax bureau. , and the signature mechanism of the electronic tax bureau is attached to the electronic invoice. [0003] Generally speaking, after the merchant issues the electronic invoice, in order to facilitate inspection and use at any time, the electronic invoice data needs to be stored in the database. At present, when storing electronic invoice data, traditional relational databases that are generally applicable to data storage and management in various industries are generally used to s...
