:area Valid operands for the AND operator are TRUE , FALSE , or NULL . The following table shows how the AND operator is evaluated based on its two operands: TRUE FALSE NULL TRUE TRUE FALSE NULL FALSE ... the expression false.

When neither operand is NULL (a case not shown in the table), the operator evaluates to either TRUE or FALSE . In this case, == is equivalent
