What are SQL timestamp functions and how do I use them?

SQL timestamp functions are used to manipulate and format date and time values in SQL databases. They allow you to perform operations like getting the current timestamp, formatting dates, and calculating differences between timestamps.

Can you give me an example of how to get the current timestamp?

Sure! You can use the CURRENT_TIMESTAMP function in SQL to get the current date and time. For example: SELECT CURRENT_TIMESTAMP;.

How can I format a timestamp in a specific way?

You can use the FORMAT() function or DATE_FORMAT() in MySQL. For example: SELECT DATE_FORMAT(NOW(), '%Y-%m-%d %H:%i:%s'); will format the timestamp as 'YYYY-MM-DD HH:MM:SS'.

What about calculating the difference between two timestamps?

You can use the TIMESTAMPDIFF() function. For example: SELECT TIMESTAMPDIFF(DAY, '2023-01-01', '2023-01-10'); will return the difference in days.
