How to avoid division by zero?

In Postgres, we can perform arithmetic operations like addition, subtraction, multiplication, and division. When an integer is divided by Zero it throws a zero division error and we have to solve the zero division error by ourselves in PostgreSQL. There are methods available that are super useful for handling zero-division errors. Some of the methods are as follows:

1. Using NULLIF() Function
2. Using Case Statement to Handle Zero Division Error

Look at the below image to understand what zero zero-division error looks like.

Explanation: As we can see in the above image, when we try to divide 10 by Zero we get an error, but handling these errors is important. When working on large projects it is important to solve this arithmetic error or it will create havoc later on.

In PostgreSQL, dividing an integer by zero can lead to a zero division error, which can cause problems in database operations. However, PostgreSQL provides useful methods to handle this error effectively.

We’ll learn various techniques like using the NULLIF() function and the CASE statement to address zero division errors. By understanding and implementing these methods, we can ensure smooth and error-free arithmetic operations in your PostgreSQL database.
