Struct datafusion_expr::logical_plan::SubqueryAlias

pub struct SubqueryAlias {
    pub input: Arc<LogicalPlan>,
    pub alias: String,
    pub schema: DFSchemaRef,
}

Aliased subquery

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

input: Arc<LogicalPlan>

The incoming logical plan

alias: String

The alias for the input relation

schema: DFSchemaRef

The schema with qualified field names
