An example of an AI chatbot conversation about SQL query best practices.
What are some best practices for writing SQL queries?
Some best practices include using meaningful names for tables and columns, avoiding SELECT *, and using JOINs instead of subqueries when possible.
Why should I avoid using SELECT *?
Using SELECT * can lead to performance issues, as it retrieves all columns, which may not be necessary for your query.
Can you explain the importance of indexing?
Indexing improves query performance by allowing the database to find rows faster, especially in large tables.
What about using comments in my SQL code?
Using comments helps document your code, making it easier for others (or yourself) to understand the logic later.
