How to use Avg, Min, Max and request this functions to neglect zero values. If I have the Sql statement: Select Sum(Field1), Avg(Field2) From
Where <...> Group by <....>, And I want the average to be calculated with only values greater than zero. "Avg(Field2>0)" ??

Try the following:

Select avg(Field1), sum(Field1) from (select Field1 from
where Field1 > 0);

Hope this helps......

Or, removeing an entire level of subquery:

Select AVG(field_1),SUM(field_1)
from table_1
where NVL(field_1,0) !=0

No point getting over complex.
