How to Avoid the “Divide by Zero” Error in SQLite?
Let’s understand why the “divide by zero” error occurs. In mathematics, division by zero is undefined because it leads to infinite or undefined results. Similarly, SQLite throws an error when attempting to divide by zero to prevent unexpected or incorrect query results. Below are the methods that help us to Avoid the “Divide by Zero” Error in SQLite are as follows:
- Using NULLIF() Operator
- Using CASE Statement
Setting up the environment
To understand How to avoid the “divide by zero” error in SQLite we need a table on which we will perform various operations and queries. Here we will consider a table called w3wiki which contains user_id, name, total_score, and contest_questions as Columns.
Table – w3wiki
How to Avoid the “Divide by Zero” Error in SQLite?
In SQLite, performing division operations where the divisor is zero can lead to the infamous “divide by zero” error. This error occurs when attempting to divide a number by zero, which is mathematically undefined. Fortunately,
SQLite provides several methods to handle and prevent this error. In this article, we will explore these methods and learn how to avoid the “divide by zero” error in SQLite queries.
