The AND logical operator chains multiple criteria together. A valid operand of an AND operator must be one of: TRUE, FALSE, and NULL. The AND operator has a higher precedence than the OR operator.

NULL represents unknown. Therefore, if one operand is NULL and the other operand is FALSE the result is FALSE, because one FALSE operand is sufficient for a FALSE result. If one operand is NULL and the other operand is either TRUE or NULL, the result is NULL (unknown).

The following table shows how the AND operator is evaluated based on its two operands:

	TRUE	FALSE	NULL
TRUE	TRUE	FALSE	NULL
FALSE	FALSE	FALSE	FALSE
NULL	NULL	FALSE	NULL

BNF: conditional_term ::= conditional_term AND conditional_factor
