Enum TableFactor

pub enum TableFactor {
    Table {
        name: ObjectName,
        alias: Option<TableAlias>,
        as_of: Option<AsOf>,
    },

NestedJoin(Box<TableWithJoins>)

Represents a parenthesized table factor. The SQL spec only allows a join expression ((foo <JOIN> bar [ <JOIN> baz ... ])) to be nested, possibly several times.

The parser may also accept non-standard nesting of bare tables for some dialects, but the information about such nesting is stripped from AST.

Trait Implementations

impl Clone for TableFactor

fn clone(&self) -> TableFactor

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TableFactor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TableFactor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TableFactor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TableFactor

fn eq(&self, other: &TableFactor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
