How do you handle divide by 0 in SQL query?
Let’s modify our initial query using the SQL NULLIF statement. We put the following logic using the NULLIF function to remove the divide by zero error from SQL: Use the NULLIF function on the denominator with the value of the second argument zero. If the value of the first argument is also zero, this function returns null.

What error will occur if you divide by 0?
Any number divided by zero gives the answer “equals infinity”. Unfortunately, no data structure in the programming world can store an infinite amount of data. Therefore, if any number is divided by zero, we get the arithmetic exception.
What causes a divide by zero error?
Division error messages occur when the computer or software attempts to run a process that performs mathematical division by zero, which is an illegal operation. This error message can also be caused by a computer or software limitation or a conflict with the computer’s memory.
How can we avoid divide by zero error encountered in SQL Server?
There are three ways to avoid the “Division By Zero Found” error in your SELECT statement and they are as follows:
- CASE statement.
- NULLIF/ISNULL functions.
- DISABLE ARITHABORT and DISABLE ANSI_WARNINGS.
How do I stop dividing by zero?
How to avoid division by zero errors
- Refactor the problem. Arguably the (mathematically) cleanest method of avoiding division-by-zero errors is to multiply quantities, rather than divide one by the other.
- Add Modelica. constants.
- Use max / min to avoid zero.
- Detect zero quantities.
- Conclusions.
What is the difference between 0 1 and 0?
Simply because 0/0 could result in any of the values on the number line, while 1/0 is not equal to any value on the number line.
How do you fix a divide by zero error?
error when a number is divided by zero (0)… To correct the error, do any of the following:
- Make sure the divisor in the function or formula is not zero or a blank cell.
- Change the cell reference in the formula to another cell that does not have a zero (0) or blank value.
How do you stop division on zero error?
How do I stop dividing by zero error in Python?
Solution 1 Python cannot divide a number by zero. Before performing a division or modulo operation, it must be verified that the denominator is not zero.

How to remove divide by zero error from SQL?
We put in the following logic using the NULLIF function to remove the divide-by-zero error from SQL: If the value of the first argument is also zero, this function returns a null value. In SQL Server, if we divide a number with null, the result is also null. Run this modified query. We can see the NULL output because the denominator contains the value zero.
How does NULLIF prevent division by zero in SQL?
So NULLIF avoids the divide-by-zero error by making COLUMN2 null. The IFNULL, in turn, converts the null result of the division to -1. My table now looks like this: By using these approaches, we can all prevent division by zero from happening again! You can get more information about the NULLIF function on the IBM website here.
What happens if the first argument is zero in SQL Server?
If the value of the first argument is also zero, this function returns null. In SQL Server, if we divide a number with null, the output is also null. If the value of the first argument is not zero, it returns the value of the first argument and the division is performed as standard values.
Can a denominator be zero in a SQL query?
You want to perform division on your SQL query, but the denominator is an expression that can be zero. The database will give you an error when the denominator is zero. Our database has a table called investor_data with data in the following columns: id, investor_year, price_per_share, income and expenses.
