An example of an AI chatbot conversation about date and time data types in SQL.
What are the different date and time data types in SQL?
In SQL, the main date and time data types include DATE, TIME, DATETIME, TIMESTAMP, and INTERVAL. Each serves different purposes.
Can you explain the difference between DATETIME and TIMESTAMP?
Sure! DATETIME stores the date and time without timezone information, while TIMESTAMP includes timezone and is affected by time zone changes.
Which one should I use for storing user login times?
It's generally better to use TIMESTAMP for user login times, as it accounts for timezone changes and provides more accurate tracking.
Are there any limitations to these data types?
Yes, each data type has its own limitations, such as range and precision. For example, DATETIME can store dates from 1753 to 9999, while TIMESTAMP has a smaller range.
