Understand indexes to write better queries

by | May 18, 2023

It is easy to learn how to query a database for information. SQL is a declarative language, meaning we tell the engine what to get, not how to get it. Some queries are fast, others are slow. We have all heard that an index will make the query faster, and often the solution to performance problems is indeed indexes. Why is that? What are they? How do you use them? With a good understanding of what indexes are and how the engine uses them, and by writing our queries with indexes in mind, we can make queries perform much faster.
