Use descriptive names that indicate the purpose of each column.\n2. **Use aliases**: Use table aliases to shorten long table names and improve readability.\n3. **Use meaningful joins**: Use explicit joins (e.g., `INNER JOIN`, `LEFT JOIN`) instead of implicit joins (e.g., `FROM table1, table2 WHERE table1.id = table2.id`).\n4. **Use subqueries wisely**: Avoid using subqueries in the `WHERE` clause, as they can lead to performance issues. Instead, use joins or CTEs (Common Table Expressions).\n5. **Avoid using `SELECT *`**: Specify only the columns you need to reduce data transfer and improve performance.\n6. **Use `EXISTS` instead of `IN`**: When checking if a value exists in a subquery, use `EXISTS` instead of `IN` to improve performance.\n7. **Use `NOT IN` instead of `NOT EXISTS`**: When checking if a value does not exist in a subquery,","usage":{"prompt_tokens":48,"completion_tokens":256,"total_tokens":304,"prompt_tokens_details":{"cached_tokens":0}}}}]
