OK, just to add a point to this - Count(fieldName) counts the non-null
records, while Count(*) will ALWAYS return the count of all records
Count(fieldName) is useful if you want to know how many records have a field
with a value, otherwise it's easier to Count(*) (unless you can guarantee
the record has entries, like an Identity)
