Re: MINUS--Sql help

Rivandra,

The minus operator is a set operator. It subtracts one result set from another. That is, the rows from the second result set that exist in the first result set are removed from the first result set, and the remaining rows are returned.

To substract one sql numeric result from another, use sqlplus variables.

col a new_value a_hold
select 15 a from dual;

• a_hold now contains 15

select 25 - &a_hold from dual;

will provide the desired result.

hth,

Yosi
