description | SQL statements are used to retrieve information from a database. In most cases, these queries are executed very slowly, the reason for this is the low quality of their writing. For better performance, we need to use faster and more efficient queries. This article shows you how to optimize SQL queries for better performance. The topic of query optimization is very broad, but we will try to cover the most important aspects of this issue. In this paper, I do not focus on in–depth database analysis, but focus on simple hints and tips for setting up queries that can be used to immediately increase productivity.
