Abstract

The invention relates to an online migration method based on a SQL database. The method includes determining a database to be operated, constructing a second SQL database structure in the database to be operated, and operating instructions in the second SQL data to operate the database to be operated; Obtain the type of operation instruction in the first SQL database; create the operation model of the database to be operated, and determine the operation cycle of the operation of the database to be operated and the operation with the largest number of executions in the cycle according to the operation model; when migrating the SQL database, execute according to the cycle The number of operations is arranged in descending order to obtain an operation priority list, and the operation instructions in the first SQL database are migrated to the second SQL database according to the order in the operation priority list. During data migration, data migration is performed according to the operation priority, so that during the migration period, the operation of the database to be operated can be performed without interruption, and the stability and security of the online migration database can be improved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to an online migration method based on an SQL database. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to the data structure. SQL database, as a kind of operation command set specially established for database, is a fully functional database language. When migrating the database, it is also necessary to migrate the SQL database as needed, so as to realize the query and modification of the database according to the operation command set in the SQL database. [0003] However, when migrating the SQL database, due to the huge and complicated data volume, it takes a long time, and because the time-consuming is too long, the operation of the database will also be delayed, which will affect the normal operation of the database, resulting in inconvenient. Contents of the invention [0004] Therefore, the present inven...
