Description
Indicates the data type of the calculated value.
Read DataType to determine the data type of the value calculated by the aggregate. This may differ from the data type of the fields that are summarized. For example, an aggregate that counts non-null fields will return an integer (ftInteger), even if the records themselves are some other type.
