AND TRUE if both Boolean expressions are TRUE.
ANY TRUE if any one of a set of comparisons are TRUE.
BETWEEN TRUE if the operand is within a range.
EXISTS TRUE if a subquery contains any rows.
IN TRUE if the operand is equal to one of a list of expressions.
LIKE TRUE if the operand matches a pattern.
NOT Reverses the value of any other Boolean operator.
OR TRUE if either Boolean expression is TRUE.
SOME TRUE if some of a set of comparisons are TRUE.
