Message representing a single field of a struct.
.. attribute:: name
The name of the field. For reads, this is the column name.
For SQL queries, it is the column alias (e.g., "Word" in
the query "SELECT 'hello' AS Word"), or the column name
(e.g., "ColName" in the query
"SELECT ColName FROM Table"). Some columns might have an
empty name (e.g., "SELECT UPPER(ColName)"). Note that a
query result can contain multiple fields with the same name.
