What are some effective SQL optimization tips?
To optimize SQL queries, consider using indexes, avoiding SELECT *, and analyzing query execution plans.
Can you explain how indexes improve performance?
Indexes speed up data retrieval by allowing the database to find rows faster without scanning the entire table.
What about using joins? Any tips?
Use INNER JOINs instead of OUTER JOINs when possible, and ensure you're joining on indexed columns.
How can I analyze my query execution plans?
You can use the EXPLAIN statement in SQL to see how your queries are executed and identify bottlenecks.
