From the Right operand combo box, specify the right operand of an expression.

If the right operand is a value, type the value in the field.

To apply a unary operator to the right operand you have specified, from the Unary operator pull-down menu, select Right operand and then the unary operator you want to apply.

To add the expression you have specified to the Left operand and Right operand lists, select Add to operand lists. The expression you have specified is displayed in the Expression field.

The list shows the columns in the table or view you specified in the Table/view field on the UPDATE Details window. The columns are unqualified, and have the form <column name>. The list also shows any expressions you have added.

If an operator is not specified in the Operator field, Right operand is not available.
