Or Operator
Performs a logical disjunction on two expressions.
result = expression1 Or expression2
Arguments
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 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 | The result is | | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 1 | |
