What are the best practices for writing SQL commands?
Some best practices include using meaningful names for tables and columns, avoiding SELECT *, and using comments for clarity.
Why should I avoid using SELECT *?
Using SELECT * can lead to performance issues and makes your queries less clear. It's better to specify only the columns you need.
How can I improve the performance of my SQL queries?
You can improve performance by indexing columns used in WHERE clauses, avoiding unnecessary joins, and analyzing query execution plans.
What is the importance of using transactions in SQL?
Transactions ensure data integrity by allowing you to group multiple operations into a single unit that can be committed or rolled back.
