Struct CallSubquery 

pub struct CallSubquery {
    pub input: PlanNodeId,
    pub inner: PlanNodeId,
    pub new_vars: Vec<VarId>,
}

CALL { ... } subquery: for each upstream row, runs the inner sub-plan with the upstream row as its initial argument, then emits the cartesian product of (upstream row, inner row) for each inner row produced. new_vars are the VarIds the inner RETURN exposes to the outer scope.

Fields

input: PlanNodeId

inner: PlanNodeId

new_vars: Vec<VarId>
