pub struct Field {
pub name: Option<String>,
pub type_: Option<Type>,
}
Expand description
Message representing a single field of a struct.
This type is not used in any activity, and only used as part of another schema.
Fields§
§name: Option<String>
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.
type_: Option<Type>
The type of the field.
