An example of an AI chatbot conversation about implementing timestamps in a database.
How do I implement timestamps in a database?
To implement timestamps in a database, you can use a column with a data type that supports date and time, like DATETIME or TIMESTAMP.
What are the differences between DATETIME and TIMESTAMP?
DATETIME stores the date and time without timezone information, while TIMESTAMP is timezone-aware and adjusts based on the server's timezone.
Can I automatically set the timestamp when a record is created?
Yes, you can set a default value for the timestamp column to the current time using DEFAULT CURRENT_TIMESTAMP.
What about updating the timestamp when a record is modified?
You can use a trigger or set the timestamp column to update automatically with ON UPDATE CURRENT_TIMESTAMP.
