And Operator

Description

Performs a logical conjunction on two expressions.

Syntax

result = expression1 And expression2

The And operator syntax has these parts:

Part	Description
result	Any numeric variable.
expression1	Any expression.
expression2	Any expression.

Remarks

If, and only if, both expressions evaluate to True, result is True. If either expression evaluates to False, result is False. The following table illustrates how result is determined:

If expression1 is	And expression2 is	The result is
True	True	True
True	False	False
True	Null	Null
False	True	False
False	False	False
False	Null	False
Null	True	Null
Null	False	False
Null	Null	Null

The And 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	0
1	0	0
1	1	1
