DIV0NULL¶

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

Syntax¶

DIV0NULL( <dividend> , <divisor> )

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.

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

As shown in the following example, the DIV0NULL function performs division like the division operator (/):

SELECT 1/2;

+----------+
|      1/2 |
|----------|
| 0.500000 |
+----------+

SELECT DIV0NULL(1, 2);

+----------------+
| DIV0NULL(1, 2) |
|----------------|
|       0.500000 |
+----------------+

Unlike the division operator, DIV0NULL returns a 0 (rather than reporting an error or returning NULL) when the divisor is 0 or NULL.

SELECT 1/0;
100051 (22012): Division by zero

SELECT DIV0NULL(1, 0);

+----------------+
| DIV0NULL(1, 0) |
|----------------|
|       0.000000 |
+----------------+

SELECT 1/NULL;

+--------+
| 1/NULL |
|--------|
|   NULL |
+--------+

SELECT DIV0NULL(1, NULL);

+-------------------+
| DIV0NULL(1, NULL) |
|-------------------|
|          0.000000 |
