Enum SetOpType 

pub enum SetOpType {
    Union,
    UnionAll,
    Intersect,
    IntersectAll,
    Except,
    ExceptAll,
}

Type of set operation.

Variants

Union

UNION - combines results, removes duplicates

UnionAll

UNION ALL - combines results, keeps duplicates

Intersect

INTERSECT - returns common rows, removes duplicates

IntersectAll

INTERSECT ALL - returns common rows, keeps duplicates

Except

EXCEPT - returns rows in first query not in second, removes duplicates

ExceptAll

EXCEPT ALL - returns rows in first query not in second, keeps duplicates

Implementations

impl SetOpType

pub const fn as_sql(&self) -> &'static str

Get the SQL keyword for this set operation.

Trait Implementations

impl Clone for SetOpType

fn clone(&self) -> SetOpType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetOpType

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

Formats the value using the given formatter.

impl PartialEq for SetOpType

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