Abstract

The invention provides a multi-database caption display method and device based on the SQL (structured query language) sentence. The method comprises the following steps: receiving access settings of users to multiple databases and connecting multiple databases simultaneously through an ADODB (active data objects data based) assembly according to the access settings; receiving the SQL sentences input into the databases by users and carrying out data query in corresponding databases according to the SQL sentences; and displaying the data resulting from the data query as the content of image-text captions. The method and device in the invention can help reduce workload and maximally achieve easy access to databases and unified data query.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a multi-database subtitle broadcasting method and device based on SQL statements. Background technique [0002] At present, TV stations, mobile media and other broadcasters have a wide range of broadcasting needs for information videos, and they are different. The broadcasting content is generally obtained from the database. For different forms of subtitle broadcasting, the data storage methods are also different. Same, that is, broadcast content comes from various databases. [0003] Database (Database) is a warehouse that organizes, stores and manages data according to the data structure. It is also defined as: a database is a collection of data organized according to a certain data model and stored in secondary storage. This kind of data collection has the following characteristics: it is not repeated as much as possible, and serves multiple applications of a specific organ...
