Struct google_spanner1::Field
source · pub struct Field {
pub type_: Option<Type>,
pub name: Option<String>,
}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§
§type_: Option<Type>The type of the field.
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.
