MySQL automatically converts a date or time value to a number if the value is used in a numeric context.

Solution (By Examveda Team)

This question is about how MySQL handles dates and times when you use them in calculations. Let's break it down:
What does it mean to use a date or time in a "numeric context"?
This means you're trying to do math with a date or time value. For example, adding two dates together, subtracting a date from a number, or comparing a date to a numerical value.
Does MySQL automatically convert dates and times to numbers for these calculations?
The answer is Option A: True.
MySQL is smart enough to understand that you're working with dates and times in a mathematical way, so it will automatically convert them to numerical values behind the scenes. This makes it easier for you to work with these values in your calculations.
Example:
Let's say you have a date stored in a column called 'order_date' and you want to find out how many days ago the order was placed. You could use this SQL query:
```sql SELECT DATEDIFF(CURRENT_DATE(), order_date) AS days_since_order FROM orders; ```
In this query, MySQL is converting both `CURRENT_DATE()` (which returns the current date) and `order_date` to numerical values so it can perform the subtraction. This allows you to get the difference between the two dates in days.
