Struct postgres_parser::sys::SetToDefault

#[repr(C)]pub struct SetToDefault {
    pub xpr: Expr,
    pub typeId: Oid,
    pub typeMod: int32,
    pub collation: Oid,
    pub location: c_int,
}

Placeholder node for a DEFAULT marker in an INSERT or UPDATE command.

This is not an executable expression: it must be replaced by the actual column default expression during rewriting. But it is convenient to treat it as an expression node during parsing and rewriting.

Fields

xpr: Expr

typeId: Oid

typeMod: int32

type for substituted value

collation: Oid

typemod for substituted value

location: c_int

collation for the substituted value
