Struct SelectPlan 

pub struct SelectPlan {
    pub tables: Vec<TableRef>,
    pub projections: Vec<SelectProjection>,
    pub filter: Option<Expr<'static, String>>,
    pub aggregates: Vec<AggregateExpr>,
    pub order_by: Vec<OrderByPlan>,
}

Logical query plan for SELECT operations.

Fields

tables: Vec<TableRef>

Tables to query. Empty vec means no FROM clause (e.g., SELECT 42). Single element for simple queries, multiple for joins/cross products.

projections: Vec<SelectProjection>

filter: Option<Expr<'static, String>>

aggregates: Vec<AggregateExpr>

order_by: Vec<OrderByPlan>
