Struct postgres_parser::sys::FromExpr

#[repr(C)]pub struct FromExpr {
    pub type_: NodeTag,
    pub fromlist: *mut List,
    pub quals: *mut Node,
}

FromExpr represents a FROM ... WHERE ... construct

This is both more flexible than a JoinExpr (it can have any number of children, including zero) and less so we don't need to deal with aliases and so on. The output column set is implicitly just the union of the outputs of the children.

Fields

type_: NodeTag

fromlist: *mut List

quals: *mut Node

List of join subtrees
