You can use the AS keyword to change the default exp_xx to something a little more meaningfull. For instance if your using the View/Query Designer in the expression builder you can put:
COUNT(table.field1) AS nCount
or
(table.field1+table.field2) AS nTotal
and if you are handcoding the viw/query you can use the same syntax such as:
SELECT COUNT(table.field1) AS nCount, (table.field1+table.field2) AS nTotal;
FROM table
