What are some common SQL optimization mistakes to avoid?
Some common mistakes include not using indexes, writing inefficient queries, and neglecting to analyze query performance.
Can you explain how indexes can improve performance?
Indexes speed up data retrieval by allowing the database to find rows faster, reducing the need for full table scans.
What about using joins? Are there mistakes to avoid there?
Yes, avoid using too many joins in a single query, as it can lead to performance issues. Always ensure you're joining on indexed columns.
How can I analyze the performance of my SQL queries?
You can use tools like EXPLAIN or query analyzers to see how your queries are executed and identify bottlenecks.
