How can I use timestamps in my SQL queries?

You can use timestamps in SQL queries to filter records based on date and time. For example, you can use the WHERE clause to select records from a specific date range.

Can you show me an example of a query that filters by a specific date?

Sure! Here's an example: SELECT * FROM orders WHERE order_date = '2023-10-01'; This will return all orders placed on October 1, 2023.

What if I want to filter records from the last 30 days?

You can use the NOW() function along with INTERVAL. For example: SELECT * FROM orders WHERE order_date >= NOW() - INTERVAL 30 DAY; This will give you all orders from the last 30 days.

Are there any functions to format timestamps in SQL?

Yes, you can use functions like DATE_FORMAT() in MySQL or TO_CHAR() in PostgreSQL to format timestamps according to your needs.
