Enum SetOp 

pub enum SetOp {
    Union,
    Except,
    Intersect,
}

A SQL set operation that combines result sets from multiple queries.

Used by ExprSetOp to specify how multiple query results are combined.

Examples

use toasty_core::stmt::SetOp;

let op = SetOp::Union;
assert_eq!(op.to_string(), "UNION");

Variants

Union

Combines results from multiple queries, including duplicates.

Except

Returns rows from the first query that are not in the second.

Intersect

Returns only rows common to both queries.

Trait Implementations

impl Clone for SetOp

fn clone(&self) -> SetOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetOp

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

Formats the value using the given formatter.

impl Display for SetOp

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

Formats the value using the given formatter.

impl PartialEq for SetOp

fn eq(&self, other: &SetOp) -> 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 Copy for SetOp
