Performs a logical disjunction on two expressions.
result = expression1 Or expression2
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 |
