Struct mz_sql_parser::ast::defs::query::Query

pub struct Query<T: AstInfo> {
    pub ctes: CteBlock<T>,
    pub body: SetExpr<T>,
    pub order_by: Vec<OrderByExpr<T>>,
    pub limit: Option<Limit<T>>,
    pub offset: Option<Expr<T>>,
}

The most complete variant of a SELECT query expression, optionally including WITH, UNION / other set operations, and ORDER BY.

Fields

ctes: CteBlock<T>

WITH (common table expressions, or CTEs)

body: SetExpr<T>

SELECT or UNION / EXCEPT / INTERSECT

order_by: Vec<OrderByExpr<T>>

ORDER BY

limit: Option<Limit<T>>

LIMIT { <N> | ALL } FETCH { FIRST | NEXT } <N> { ROW | ROWS } | { ONLY | WITH TIES }

offset: Option<Expr<T>>

OFFSET <N> { ROW | ROWS }

impl<T: Ord + AstInfo> Ord for Query<T>

fn cmp(&self, other: &Query<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<T: PartialEq + AstInfo> PartialEq for Query<T>

fn eq(&self, other: &Query<T>) -> 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<T: PartialOrd + AstInfo> PartialOrd for Query<T>

fn partial_cmp(&self, other: &Query<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
