Struct postgres_parser::sys::ColumnRef

#[repr(C)]pub struct ColumnRef {
    pub type_: NodeTag,
    pub fields: *mut List,
    pub location: c_int,
}

ColumnRef specifies a reference to a column, or possibly a whole tuple

The "fields" list must be nonempty. It can contain string Value nodes (representing names) and A_Star nodes (representing occurrence of a '*'). Currently, A_Star must appear only as the last list element the grammar is responsible for enforcing this!

Note: any container subscripting or selection of fields from composite columns is represented by an A_Indirection node above the ColumnRef. However, for simplicity in the normal case, initial field selection from a table name is represented within ColumnRef and not by adding A_Indirection.

Fields

type_: NodeTag

fields: *mut List

location: c_int

field names (Value strings) or A_Star
