Numeric Functions

DIV0

Performs division like the division operator (/), but returns 0 when the divisor is 0 (rather than reporting an error).

Syntax

DIV0( <dividend> , <divisor> )

Arguments

dividend

Numeric expression that evaluates to the value that you want to divide.

divisor

Numeric expression that evaluates to the value that you want to divide by.

Returns

The quotient. If the divisor is 0, the function returns 0.

Examples

As shown in the following example, the DIV0 function performs division like the division operator (/):

SELECT 1/2;
+----------+                                                                    
|      1/2 |
|----------|
| 0.500000 |
+----------+
SELECT DIV0(1, 2);
+------------+                                                                  
| DIV0(1, 2) |
|------------|
|   0.500000 |
+------------+

Unlike the division operator, DIV0 returns a 0 (rather than reporting an error) when the divisor is 0.

select 1/0;
100051 (22012): Division by zero
SELECT DIV0(1, 0);
+------------+                                                                  
| DIV0(1, 0) |
|------------|
|   0.000000 |
+------------+
