When you use the SELECT query to obtain data, your results will be stored in a “result table.” This table of results is called the “result set.” The SQL SELECT statement is used to select data from a database. The remainder of this guide will focus on tips related to SELECT specifically. One of the most commonly used queries is the SELECT query. Some queries will be used more than others, and it’s important to make sure you use these efficiently, within the greater context of tuning your database more generally. There are numerous ways to write SQL queries, and different parameters you can attach to them. Particularly on an enterprise scale, every query matters. If your queries are inefficient (i.e., if you’re asking for large amounts of data when you only need a small amount), your database responses will be slow, and your applications and services may suffer in terms of performance. By performing regular SQL performance tuning, you can fix common SQL performance issues, like inefficient indexing and unoptimized SQL queries. In SQL tuning, you look at the SQL queries you’re using to access and navigate the database and try to make them run in the shortest possible time.

Most tuning gains will be obtained from focusing on your SQL queries and optimizing how they function. SQL tuning is essentially the process of optimizing a database for better performance. Speeding Up SELECT Query in Oracle What Is SQL Tuning? This includes using SolarWinds ® Database Performance Analyzer (DPA) or a similar tool for conducting query tuning.īest Practices for Query Tuning in Oracle In this guide, I’ll start with a discussion of SQL tuning and the basics of why it’s important then I’ll set out six best practices for query tuning in Oracle, and how to make SELECT query faster in Oracle. In Oracle, SQL query tuning is an important part of speeding up database performance. In most cases when tuning a database, you’ll focus on SQL query tuning. When working with Oracle databases, there are times when you need to optimize and homogenize the database to ensure good performance.
