Function unresolve

src/sql/src/normalize.rs:134–143

Unnormalizes an item name. This is the inverse of the [`unresolved_item_name`] function.

(name: FullItemName)

///
/// This is the inverse of the [`unresolved_item_name`] function.
pub fn unresolve(name: FullItemName) -> UnresolvedItemName {
    // TODO(parkmycar): Refactor FullItemName to use `Ident`.
    let mut out = vec![];
    if let RawDatabaseSpecifier::Name(n) = name.database {
        out.push(Ident::new_unchecked(n));
    }
    out.push(Ident::new_unchecked(name.schema));
    out.push(Ident::new_unchecked(name.item));
    UnresolvedItemName(out)
}

/// Converts an `UnresolvedItemName` to a `FullItemName` if the
/// `UnresolvedItemName` is fully specified. Otherwise returns an error.
