Enum TableFactor

pub enum TableFactor {
    Table {
        name: ObjectName,
        alias: Option<TableAlias>,
        args: Vec<FunctionArg>,
        with_hints: Vec<Expr>,

    TableFunction {
        expr: Expr,

    },
    NestedJoin(Box<TableWithJoins>),
}

A table name or a parenthesized subquery with an optional alias

Variants

Table

Fields

name: ObjectName

alias: Option<TableAlias>

args: Vec<FunctionArg>

Arguments of a table-valued function, as supported by Postgres and MSSQL. Note that deprecated MSSQL FROM foo (NOLOCK) syntax will also be parsed as args.

with_hints: Vec<Expr>

MSSQL-specific WITH (...) hints such as NOLOCK.

Derived

Fields

lateral: bool

subquery: Box<Query>

alias: Option<TableAlias>

TableFunction

TABLE(<expr>)[ AS <alias> ]

Fields

expr: Expr

alias: Option<TableAlias>

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 duplicate 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.
