RELATIONAL CONDITION:
We know that a relational condition specifies a comparison between two operands and has the form.
Operand-1 relational-operator operand-2
where the relational-operator can be anyone of the shown below:
IS [NOT] GREATER THAN
IS [NOT] > THAN
IS [NOT] LESS THAN
IS [NOT] < THAN
IS [NOT] EQUAL TO
IS [NOT] =
It was acknowledged earlier that the operands can be an identifier or a literal. Though, either operand can also be an arithmetic expression but should contain at least one reference to an identifier. Occasionally, operand-1 and operand-2 are respectively referred to as the subject and object of the relational condition.
