There are different types of date and time data types used in SQL. Here are a few:​​

• DATE stores date values in the following format: YYYY-MM-DD.

  • Example: 2024-03-02.

• TIME stores time values in the following format: HH:MM:SS.

  • Example: 14:30:00.

• DATETIME stores both date and time values in the following format: YYYY-MM-DD HH:MM:SS. 

  • Example: 2024-03-02 14:30:00.

• TIMESTAMP stores date and time with time zone information in the following format: YYYY-MM-DD HH:MM:SS UTC.

  • Example: 2024-03-02 14:30:00 UTC.

​​

You can extract different components from date and time values. For example, from a DATETIME value of 2024-03-02 14:30:00, you can extract the date 2024-03-02, the time 14:30:00, the year 2024, the month 03, the hour 14, and so on.

​

DATETIME and TIMESTAMP are more commonly used than DATE and TIME because they store both the date and time together, making them more versatile.
