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

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
