Abstract

The invention discloses a data uniqueness identification method in a database. The method comprises the following steps: defining a data identification column, namely selecting original data fields, defining a data identification field, selecting a related column of which uniqueness needs to be judged, and adding a new data identification column; generating data unique identification, namely generating the data unique identification for the selected column, and storing a generation result in the newly added identification column for later use; judging data uniqueness, namely comparing a generated uniqueness identification column with a uniqueness identification column of existing data in a database, wherein it is considered that same data exists if same uniqueness identification exists, and it is considered that the same data does not exist if the same uniqueness identification does not exist; when the same data exists, performing related processing on the repeated data according to business scene requirements; and when the same data does not exist, storing new data into the database and adding data initial version identification. According to the invention, the technical problems that only the uniqueness of data records can be kept, and the uniqueness of recorded data content cannot be effectively identified are solved.

Description

technical field [0001] This application relates to the field of front-end development, in particular, to a method for uniquely identifying data in a database. Background technique [0002] The current data unique identification methods mainly include: digital serial number, universally unique identifier (UUID, Universally Unique Identifier), globally unique identifier (GUID, Globally Unique Identifier), time stamp and other methods. [0003] Currently, the disadvantages of existing technologies on the market: [0004] It can only maintain the uniqueness of the data record itself, but cannot effectively identify the uniqueness of the recorded data content. [0005] Aiming at the problem that the uniqueness of the recorded data content cannot be effectively identified in related technologies, no effective solution has been proposed so far. Contents of the invention [0006] The main purpose of this application is to provide a method for uniquely identifying data in a datab...
