Abstract

The invention discloses a database data verification method and device. The method comprises the following steps of: respectively setting a data type mapping rule corresponding to each database according to data types supported by a first database and a second database; and respectively converting data in the first database and the second database into intermediate data according to the data type mapping rules corresponding to the databases, and judging whether the converted intermediate data are the same. Through the database data verification method and device, effective verification can be carried out on the consistency of the data after data migration.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for verifying database data. Background technique [0002] With the application of open source databases and the development of cloud computing, there is an increasing demand for data migration across databases. The so-called data migration refers to exporting the data of a database (source database) according to the provided data migration tools according to the specified steps and rules, and loading it into the target database in the form of other statements or data files. [0003] However, after data is migrated between databases, the following needs will also arise: [0004] (1) After the database is migrated between heterogeneous relational databases, data verification is required; [0005] (2) After data migration, there is no type corresponding to the data before migration. For example, if a field is TIMESTAMP WITH TIME ZONE in Oracle, tw...
