What type of operators can be used with Date and Timestamp in SQL?

• A. Addition and division
• B. Subtraction and multiplication
• C. Addition and subtraction
• D. All arithmetic operations

Answer: (C)

In SQL, the manipulation of Date and Timestamp data types typically involves operations related to time intervals, which are most commonly represented by addition and subtraction.

When adding a specific time interval (such as days, months, or years) to a Date or Timestamp, SQL allows you to adjust the date forward. Conversely, subtracting a time interval allows you to adjust the date backward. This is essential for performing calculations like determining the difference between two dates or calculating future or past dates based on a given time span.

The other types of arithmetic operations such as multiplication and division generally do not apply to Date and Timestamp types in SQL. These data types are fundamentally designed to represent points in time, and their manipulation is not conceptually aligned with multiplication or division, which are more suited for numeric data types. Therefore, addition and subtraction are the relevant operators for Date and Timestamp operations, making this choice the apt one.
