Expr(Expr)
ExprQualifiedWildcard(Expr, Vec<Ident>)
Expr is an arbitrary expression, returning either a table or a column.
Idents are the prefix of *, which are consecutive field accesses.
e.g. (table.v1).* or (table).v1.*
See also Expr::FieldIdentifier for behaviors of parentheses.
QualifiedWildcard(ObjectName, Option<Vec<Expr>>)
QualifiedWildcard and Wildcard can be followed by EXCEPT (columns)
Wildcard(Option<Vec<Expr>>)
