ChatGPT Explains: How to Speed up SQL Queries?
How to speed up SQL queries or how to make SQL queries faster?
Such a sql interview question is a very frequent interview question in many sql interview questions and answers.
Luckily, this sql tutorial for beginners will walk you through everything you need to know to deal with SQL databases in your work - or, rather, ChatGPT 4 will answer those kinds of sql interview questions for us.
chatgpt data analysis is a popular topic as is chatgpt 4 or chatgpt plus itself, but did you know that it can also answer basic tech questions like those related to sql? Here's what chatgpt 4 has to say about SQL queries..
This sql tutorial for beginners will tell you that in regards to sql indexes, ChatGPT 4 advises us not to over-index as they can slow down data modification operations.
I'd add that that happens because SQL indexes have to be updated together with the data in your sql database no matter what kind of sql database you use - mysql server, mariadb server, percona server, or others. Also, make sure that your sql indexes are actually used by your sql query.
In regards to SQL query optimization, I'd have a remark that if you use the WHERE clause, make sure that the sql index is actually used by your sql query by using EXPLAIN beforehand.
In regards to database maintenance, I'm surprised that ChatGPT 4 did not mention any database backups of your SQL databases.
Make sure to come up with a database backup plan and backup regularly.
Regarding hardware and query caching, ensure that your hardware is powerful enough to modify your database configuration file if necessary. Also, keep in mind that many database management systems such as MySQL Server, MariaDB Server, Percona Server etc. cache frequently running queries by themselves if the SQL query cache is on.
Finally, normalization and denormalization will be very useful for those dealing with bigger data sets or those who want to add redundant data to tables to achieve a goal.
