Problems solved by technology

The amount of exported data supported by these export methods is limited, and the exported data files also have data errors and limited export content. Moreover, the waiting time is long during the process of data export and conversion into the target file format, which reduces the database data processing. The efficiency of the database cannot give full play to the efficiency of database data conversion

Abstract

The invention discloses a method and a system for exporting large-batch data to Excel files. The method comprises the steps of querying a database; converting a query result into binary data; converting word files into files in meta formats; initializing the files in the meta formats; mapping the binary data to the files in the meta formats, thereby generating file streams; and converting the filestreams into the Excel files. According to the technical scheme, the process of exporting the data in batches by the database is optimized; the efficiency of exporting the data and converting the data to be in Excel file formats is improved; large-batch and one-time exporting of the data is supported; diversified demands of data processing are met; the data exporting speed is increased; the database data conversion time is shortened; and the demands of database applications in multiple scenes are met.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and a system for exporting large batches of data into Excel files. Background technique [0002] A relational database is a database built on the basis of the relational database model. Relational database products are widely used for their simple and clear concept and easy-to-understand and easy-to-learn database language. [0003] Relational databases process data in the database by means of concepts and methods such as set algebra, and are also organized into a set of formally descriptive tables. The essence of this form of tables is to load special collections of data items. These tables The data in the database can be accessed or recalled in many different ways without reorganizing the database tables. The definition of a relational database results in a table of metadata or in a formal description of tables, columns, scopes and constraints. Each table (some...
