Let’s Setup an Environment
We will use the following table to implement our approaches.
To create this table in our database, we have to execute the following MySQL queries:
Create Table name w3wiki:
CREATE TABLE w3wiki(
user_id int PRIMARY KEY,
name varchar(100),
montly_score int,
total_score int
);
Insert the value in w3wiki table:
INSERT INTO w3wiki(user_id,name, montly_score , total_score)
VALUES(01,'Vishu',50,150);
INSERT INTO w3wiki(user_id,name, montly_score , total_score)
VALUES(02,'Neeraj',45,125);
INSERT INTO w3wiki(user_id,name, montly_score , total_score)
VALUES(03,'Aayush',0,110);
INSERT INTO w3wiki(user_id,name, montly_score , total_score)
VALUES(04,'Sumit',40,100);
INSERT INTO w3wiki(user_id,name, montly_score , total_score)
VALUES(05,'Vivek',0,95);
After executing the above queries, we can observe a table has been created in our database.
How to Avoid Dividing by Zero in MySQLHow to Avoid Dividing by Zero in SQL
MySQL is an open-source relational database management system in short RDBMS. We use it to store, retrieve, and manipulate data very efficiently. In MySQL “Divide by zero error” is encountered when we try to divide one column with another column that contains some zero values.
“Diving by zero error” is a common problem while performing division in most of the data. It can eventually solve some basic step-by-step approaches.
In this article, we are going to demonstrate various methods through which we can tackle “Divide by zero error” very easily. We are going to see various approaches with clear and concise examples along with their explanations.
How to Avoid Dividing by Zero in SQL
MySQL allows us several approaches through which we can ignore dividing by zero error. There are certain built-in functions and some queries along with the where clause, can help us to achieve our goal. Below are some mentioned methods through which we can avoid dividing by zero error.
1. Using the CASE statement
2. Using NULLIF()
3. Using WHERE Clause
