Used to perform a logical disjunction on two expressions.
Syntax
result = expression1 Or expression2
The Or operator syntax has these parts:
| Part | Description |
|---|---|
| result | Any numeric variable. |
| expression1 | Any expression. |
| expression2 | Any expression. |
Remarks
If either or both expressions evaluate to True, result is True. The following table illustrates how result is determined:
| If expression1 is | And expression2 is | The result is |
|---|---|---|
| True | True | True |
| True | False | True |
| True | Null | True |
| False | True | True |
| False | False | False |
| False | Null | Null |
| Null | True | True |
| Null | False | Null |
| Null | Null | Null |
The Or operator also performs a bit-wise comparison of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following table:
| If bit in expression1 is | And bit in expression2 is | The result is |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
