Returns the actual name of the column.
string_view column_name() const;
If the column was aliased, this will be the name of the alias (e.g. in
"SELECT id AS employee_id FROM employees"
,
column_name()
will be "employee_id"
).
This is optional information - it won't be populated unless the connection
executing the query has meta_mode() == metadata_mode::full
.
No-throw guarantee.
The returned reference is valid as long as *this
is alive and hasn't been assigned to
or moved from.
