Or Operator

Used to perform a logical disjunction on two expressions.


result = expression1 Or expression2

The Or operator syntax has these parts:

Part Description
result Required; any numeric variable.
expression1 Required; any expression.
expression2 Required; 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
