Abstract

The invention discloses an automatic optimization method and device for a SQL (Structured Query Language), computer equipment and a storage medium. The method comprises the following steps: when a current script is under an execution state, according to a system performance index monitoring item set in the current script, collecting a current system performance index parameter; when the current system performance index parameter exceeds a preset index early warning value, recording the current script in an appointed path; obtaining the execution plan of the current script; if the execution plan of the current script lacks an index, automatically adding the index to the current script; if the index of the current script fails, through a forced index, carrying out script repairing to obtaina repaired script. By use of the method, system performance can be monitored in time, in addition, the SQL script which can greatly influence the system performance can be automatically optimized, andperformance problems can be quickly found and solved.

Description

technical field [0001] The present application relates to the technical field of database scripts, in particular to an SQL automatic optimization method, device, computer equipment and storage medium. Background technique [0002] A script is an executable file written in a certain format using a specific descriptive language, also known as a macro or a batch file. In the process of software development, the quality of scripts written by developers varies from person to person, and low-quality scripts bring great performance risks to the system when they are executed. Generally, the system will troubleshoot and fix the problems caused by the script after the script execution has performance problems. Due to the large number of scripts, it is impossible to locate the script that specifically causes the problem in time, resulting in low efficiency in modifying and optimizing low-quality scripts. Contents of the invention [0003] This application provides a SQL automatic o...
