Operator (on Computed Column Details)
From the Operator combo box, Select the binary operator of the expression.
Note:
If you select <none> from the list, the operator you have specified in the Operator field will be deleted. This will also delete anything you have specified in the Right operand field.
The list shows the binary operators you can specify in an expression.
If you do not specify a left operand in the Left operand field, Operator is not available.
