Abstract

The invention discloses a visiting method and a device for a relational database. The visiting method and the device for the relational database achieve a novel static mapping mechanism, are capable of quickly and accurately achieving the visit for a database, and reduce error rate in visit operation and cost consumptions in error correction. The visiting method for the relational database includes the following steps: setting service configuration information and data table configuration information, building a positioning array according to selected visiting parameters and the labels of array elements in the positioning array indicate the positions of the visiting parameters in an application service entity class, obtaining keyword information from the application service entity class, obtaining visiting expressions and the visiting parameters from the service configuration information according to the keyword information, obtaining the labels of the array elements from the data table configuration information according to the visiting parameters, finding numerical values of the visiting parameters from the entity class by using the labels, setting the numerical values of the visiting parameters into the visiting expressions, and executing the visiting expressions in the relational database.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a relational database access method and device. Background technique [0002] Relational databases are an integral part of most current information systems. Using a Java-based application system to access a relational database is a more common solution at present. This solution usually has the following two methods: [0003] The first way is to directly use Java Database Connectivity (JDBC) to access relational databases; the second way is to use open source projects (such as open source project iBatis, Hibernate, etc.) to access relational databases. [0004] There are at least the following defects in the above-mentioned existing solutions: [0005] In the first way, developers need to manually integrate the structured query language (Structured Query Language, SQL) statement to be executed into the program code, the error rate is high, and the cost of checking and elimina...
