Performs a logical disjunction on two expressions.
result = expression1 Or expression2
result
Any numeric variable.
expression1
Any expression.
expression2
Any expression.
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 | Then 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 bitwise 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 | Then result is |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
