Struct Qualify 

pub struct Qualify {
    pub this: Expression,
}

Represent a QUALIFY clause for filtering on window function results.

Supported by Snowflake, BigQuery, DuckDB, and Databricks. The predicate typically references a window function (e.g. QUALIFY ROW_NUMBER() OVER (PARTITION BY id ORDER BY ts DESC) = 1).

Fields

this: Expression

The filter predicate over window function results.

Trait Implementations

impl Clone for Qualify

fn clone(&self) -> Qualify

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Qualify

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Qualify

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Qualify

fn eq(&self, other: &Qualify) -> 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 Qualify

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
