Struct Cte 

pub struct Cte {
    pub alias: Identifier,
    pub this: Expression,
    pub columns: Vec<Identifier>,
    pub materialized: Option<bool>,
    pub key_expressions: Vec<Identifier>,
    pub alias_first: bool,
}

Represent a single Common Table Expression definition.

A CTE has a name (alias), an optional column list, and a body query. The materialized field maps to PostgreSQL’s MATERIALIZED / NOT MATERIALIZED hints. ClickHouse supports an inverted syntax where the expression comes before the alias (alias_first).

Fields

alias: Identifier

The CTE name.

this: Expression

The CTE body (typically a SELECT, UNION, etc.).

columns: Vec<Identifier>

Optional column alias list: cte_name(c1, c2) AS (...).

materialized: Option<bool>

Some(true) = MATERIALIZED, Some(false) = NOT MATERIALIZED, None = unspecified.

key_expressions: Vec<Identifier>

USING KEY (columns) for DuckDB recursive CTEs

alias_first: bool

ClickHouse supports expression-first WITH items: WITH AS

Trait Implementations

impl Clone for Cte

fn clone(&self) -> Cte

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cte

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cte

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Cte

fn eq(&self, other: &Cte) -> 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.

impl Serialize for Cte

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
