How do you divide by zero in SQL?

How do you divide by zero in SQL?

Method 1: SQL NULLIF Function

1. Use NULLIF function in the denominator with second argument value zero.
2. If the value of the first argument is also, zero, this function returns a null value.
3. If the value of the first argument is not zero, it returns the first argument value and division takes place as standard values.

How do you avoid Ora-01476 divisor to zero?

This ORA-01476 errors are related with the expression attempted to divide by zero. To solve this error, don’t use to divide by ZERO value, Use another value instead of ZERO. Or you can use NULLIF function to solve this error.

How do you divide by zero in Excel?

You can also suppress this error by nesting your division operation inside the IFERROR function. Again, using A2/A3, you can use =IFERROR(A2/A3,0). This tells Excel if your formula evaluates to an error, then return 0, otherwise return the result of the formula.

Why is divide by zero an error?

The reason that the result of a division by zero is undefined is the fact that any attempt at a definition leads to a contradiction. a=r*b. (1) But r*0=0 for all numbers r, and so unless a=0 there is no solution of equation (1).

Why can’t we divide by zero?

As much as we would like to have an answer for “what’s 1 divided by 0?” it’s sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be ​true, because anything times 0 is 0. Created by Sal Khan.

How do you handle divisor equal to zero?

There are many ways to handle this error in Oracle.

1. The first and foremost way is to enforce the business logic and try to ensure that the field doesn’t contain a 0 in the first place.
2. Use the DECODE function DECODE(FIELD2,0,0,((FIELD1/FIELD2)*100))
3. User ZERO_DIVIDE to handle a zero divisor error.

What is divisor in math?

The number that is being divided (in this case, 15) is called the dividend, and the number that it is being divided by (in this case, 3) is called the divisor. The result of the division is the quotient. Notice how you can always switch the divisor and quotient and still have a true equation: 15 ÷ 3 = 5.

Can you divide by 0 in Java?

Dividing by zero is an operation that has no meaning in ordinary arithmetic and is, therefore, undefined. According to the Java specification of the division operation, we can identify two different cases of division by zero: integers and floating-point numbers.

How to replace null values with zero using NVL function?

Replace null value with zero using NVL function. In this scenario we will try to replace the age of the employees which are null with zero so that the null values in age column of the employee table are replaced with the number zero. The NVL function will only be applied on the age column.

How do you use NULLIF to divide by zero?

If you’d like to handle division by zero gracefully, you can use the NULLIF function. NULLIF takes two arguments: the expression of interest, and the value you want to override. If the first argument is equal to the second, then NULLIF returns NULL; otherwise, it returns the first argument.

What is the result of a division by zero?

The result of a division by zero is undefined, so we make it null. You are using a programming language. As such it features conditions of course: You can put more code in the IF and ELSE block in case you want to do some logging etc. What result do you want when IO_factor_calc = 0?

What is an example of Oracle NVL function?

It then returns the modified result set as output. Given below are the examples of Oracle NVL (): Replace null value with zero using NVL function. In this scenario we will try to replace the age of the employees which are null with zero so that the null values in age column of the employee table are replaced with the number zero.
