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 & Operator of identically positioned bits in two numeric expressions and sets the corresponding bit in result according to the following truth 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
