defined as a result of a query, its name is the same as its corresponding
database column.
row_number
Specifies the row from which to retrieve the value of the cell.
GET_GROUP_CHAR_CELL restrictions
The row_number specified must be within the bounds implied by the number of rows in the record
group.  A non-existent row_number results in an index out of bounds error.
