The **SQL EXP() function** is a mathematical function that calculates the exponential value of a given number. It is commonly used in SQL queries to calculate exponential values of numbers stored in a database table.

## Syntax

The syntax of the **SQL EXP() function** is:

EXP(number)

Where number is the input value for which the exponential value needs to be calculated.

### Example

For example, if you want to calculate the exponential value of 2, you can use the following SQL query:

SELECT EXP(2);

This will return the result as 7.38905609893065. The EXP() function uses the constant value e (Euler’s number) as the base of the exponential function.

You can also use a column name as the input value for the EXP() function in a SQL query. For example, consider a table named “sales” with two columns “amount” and “id”. If you want to calculate the exponential value of the “amount” column for each row in the table, you can use the following SQL query:

SELECT id, amount, EXP(amount) as exp_amount FROM sales;

This query will return a result set with three columns: “id”, “amount”, and “exp_amount”. The “exp_amount” column will contain the exponential value of the “amount” column for each row.

In conclusion, the **SQL EXP() function** is a useful mathematical function that can be used in SQL queries to calculate exponential values. It is a handy tool for performing complex mathematical calculations in SQL queries.
