Abstract

The invention discloses a structured query language (SQL) processing method and a related device. The method comprises the following steps of: firstly, obtaining a statement constructed by utilizing an SQL; performing lexical analysis on the statement constructed by utilizing the SQL to obtain a word set of the statement constructed by utilizing the SQL; processing the word set of the statement constructed by utilizing the SQL by utilizing a preset index setting rule to obtain an updated index list corresponding to the statement constructed by utilizing the SQL; determining an original index list corresponding to the statement constructed by utilizing the SQL; and generating an index optimization suggestion of the statement constructed by utilizing the SQL according to a comparison resultof the updated index list and the original index list. According to the method, the index of the statement constructed by utilizing the SQL can be optimally optimized through the index setting rule, manual operation is not needed any more, and the optimized program performance is guaranteed while the optimization efficiency is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for processing structured query language. Background technique [0002] Structured Query Language (Structured Query Language, SQL) is a database query and programming language for accessing data and querying, updating and managing relational database systems. In the process of project development and database operation and maintenance, in order to improve program performance and reduce online failure rate, it is often necessary to optimize SQL. [0003] At present, the commonly used SQL processing method is to execute the SQL statement using the previously established index, and then manually analyze the execution result of the SQL statement. When the programmer finds that the previously established index does not meet the requirements, he will modify the previously established index by manually adjusting the index or adding an index, and use the modified index...
