Abstract

The invention belongs to the technical field of software development, and discloses a method and a device of generating an SQL statement automatically. The method comprises the steps of determining adata model corresponding to a target data table in a database according to a preset programming interface instruction input by a user, wherein the data model comprises specific annotations, the specific annotations are used for determining a correspondence between the data model and the target data table and representing necessary parameters generating standard format of SQL statements; and then invoking a preset programming interface to produce specific labels in the data model into standard format of SQL statements by using a preset generation rule, wherein each part of the standard format of SQL statement is corresponding to the specific annotation. In the method, specific annotation can be produced into standard format of SQL statement automatically according to preset generation rulesby invoking the preset programming interface only, and developers do not need to program standard format of SQL statements manually, so that the programming amount is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of software development, in particular to a method and a device for automatically generating SQL statements. Background technique [0002] In the existing database application development, the MVC architecture is usually used for development. Among them, MVC is composed of the first letters of the three words model (model), view (view), and controller (controller). It is a widely popular application architecture, and its purpose is to realize the functional division of programming systems. [0003] see figure 1 , figure 1 It is a schematic diagram of the MVC architecture relationship. The user interacts with the controller by inputting instructions and parameters, the controller passes the instructions and parameters input by the user to the data model, the data model executes business logic judgment, database access, selects different views according to the business logic, and the view feeds back the re...
