What are common SQL optimization mistakes to avoid?
Some common mistakes include not using indexes, writing inefficient queries, and neglecting to analyze query performance.
How can I identify if my queries are slow?
You can use tools like SQL Server Profiler or EXPLAIN in MySQL to analyze query performance and identify bottlenecks.
What role do indexes play in SQL optimization?
Indexes speed up data retrieval operations by allowing the database to find rows more quickly, reducing the need for full table scans.
Can you give an example of an inefficient query?
Sure! A query that uses SELECT * instead of specifying columns can be inefficient, especially with large tables.
