	Hi everyone, I'm working on a report that was created by someone else and it has a formula that uses the NVL() fuction. What does that function do exactly? It goes like this: nvl(table.field,0) Thanks a lot, Santiago

	Not familiar with this as a crystal function but I believe it is similar to a coalesce() or isnull() in SQL and it will, in your example, return a 0 when the table.field is null otherwise it returns the value from table.field.

	yes, NVL is Oracle IsNull. COALESCE is ANSI standard and works in both Oracle and SQL
