Implementation method, system and operation method for SQL statement processing

Abstract

The invention discloses a method for realizing SQL (Structured Query Language) statement processing, which comprises the following steps of: creating a packaging interface for packaging a query condition statement, and defining an input parameter of the packaging interface as a condition parameter of an object type; defining a first packaging class and an analysis tool; implementing the first encapsulation class to include encapsulation functions in one-to-one correspondence with the encapsulation interfaces, wherein the encapsulation functions are implemented to store the received condition parameters in the internal container; and implementing the analysis tool to obtain the condition parameters of the first encapsulation class for analysis to obtain encapsulation data type output conforming to the JPA framework protocol. The invention further discloses an SQL statement processing system, according to the system and the method disclosed by the invention, the aim of directly operatingthe entity class is achieved by packaging the database query statement, the operation of writing the statement is avoided, the threshold of database query operation is lowered, and the system and themethod are efficient and convenient.

Description

technical field [0001] The invention relates to the technical field of statement processing, in particular to an implementation method, system and operation method of SQL statement processing. Background technique [0002] SQL (Structured Query Language) is a database query and programming language for accessing data and querying, updating and managing relational database systems. In the current technology, the query function of SQL or HQL needs to be implemented by handwritten statements. When executing certain SQL statements, handwritten statements often take a long time and have low operating efficiency, which will seriously hinder the operation of the system. Speed, prolonging page response speed, affecting system performance, thus affecting user experience. Contents of the invention [0003] In order to solve the above problems, the inventor conceived that the handwritten statement can be replaced by encapsulating the attributes of the entity class, and the query ope...
