Struct Query

pub struct Query {
    pub with: Option<With>,
    pub body: SetExpr,
    pub order_by: Vec<OrderByExpr>,
    pub limit: Option<Expr>,
    pub offset: Option<Offset>,
    pub fetch: Option<Fetch>,
}

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

Fields

with: Option<With>

WITH (common table expressions, or CTEs)

body: SetExpr

SELECT or UNION / EXCEPT / INTERSECT

order_by: Vec<OrderByExpr>

ORDER BY

limit: Option<Expr>

LIMIT { <N> | ALL }

offset: Option<Offset>

OFFSET <N> [ { ROW | ROWS } ]

fetch: Option<Fetch>

FETCH { FIRST | NEXT } <N> [ PERCENT ] { ROW | ROWS } | { ONLY | WITH TIES }

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Display for Query

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

Formats the value using the given formatter.

impl Hash for Query

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 Query

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