Instead, use descriptive names that indicate the table's purpose and column's meaning.\n2. **Use consistent naming conventions**: Use a consistent naming convention throughout your database. For example, use camelCase or underscore notation for table and column names.\n3. **Use aliases**: Use table aliases to shorten long table names and improve readability.\n4. **Use indexes**: Create indexes on columns used in WHERE, JOIN, and ORDER BY clauses to improve query performance.\n5. **Avoid using SELECT \\***: Instead of selecting all columns, specify only the columns needed to reduce data transfer and improve performance.\n6. **Use subqueries instead of joins**: When possible, use subqueries instead of joins to improve readability and performance.\n7. **Use exists instead of in**: Use EXISTS instead of IN when checking for the existence of a record in a subquery.\n8. **Avoid using functions in WHERE clauses**: Functions like NOW() or RAND() can prevent index usage and slow down queries.\n9. **Use transactions**: Use transactions to ensure data consistency and","usage":{"prompt_tokens":48,"completion_tokens":256,"total_tokens":304,"prompt_tokens_details":{"cached_tokens":0}}}}]
