Variants

IgnoreOrRespectNulls(NullTreatment)

Indicates how NULLs should be handled in the calculation, e.g. in FIRST_VALUE on BigQuery.

Syntax:

{ IGNORE | RESPECT } NULLS ]

OrderBy(Vec<OrderByExpr>)

Specifies the the ordering for some ordered set aggregates, e.g. ARRAY_AGG on BigQuery.

Limit(Expr)

Specifies a limit for the ARRAY_AGG and ARRAY_CONCAT_AGG functions on BigQuery.

OnOverflow(ListAggOnOverflow)

Specifies the behavior on overflow of the LISTAGG function.

See https://trino.io/docs/current/functions/aggregate.html.

Having(HavingBound)

Specifies a minimum or maximum bound on the input to ANY_VALUE on BigQuery.

Syntax:

HAVING { MAX | MIN } expression

Separator(ValueWithSpan)

The SEPARATOR clause to the GROUP_CONCAT function in MySQL.

JsonNullClause(JsonNullClause)

The ON NULL clause for some JSON functions.

MSSQL JSON_ARRAY MSSQL JSON_OBJECT PostgreSQL JSON functions

JsonReturningClause(JsonReturningClause)

The RETURNING clause for some JSON functions in PostgreSQL

JSON_OBJECT

Trait Implementations

impl Clone for FunctionArgumentClause

fn clone(&self) -> FunctionArgumentClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionArgumentClause

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

Formats the value using the given formatter.

impl Display for FunctionArgumentClause

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

Formats the value using the given formatter.

impl Eq for FunctionArgumentClause

impl Hash for FunctionArgumentClause

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Ord for FunctionArgumentClause

fn cmp(&self, other: &FunctionArgumentClause) -> 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,

Restrict a value to a certain interval.

impl PartialEq for FunctionArgumentClause

fn eq(&self, other: &FunctionArgumentClause) -> 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 PartialOrd for FunctionArgumentClause

fn partial_cmp(&self, other: &FunctionArgumentClause) -> 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.

impl Spanned for FunctionArgumentClause

fn span(&self) -> Span

Return the Span (the minimum and maximum Location) for this AST node, by recursively combining the spans of its children.

impl StructuralPartialEq for FunctionArgumentClause

impl Visit for FunctionArgumentClause

fn visit<V>(&self, visitor: &mut V) -> ControlFlow<<V as Visitor>::Break>

where V: Visitor,

Visit this node with the provided Visitor.

impl VisitMut for FunctionArgumentClause

fn visit<V>(&mut self, visitor: &mut V) -> ControlFlow<<V as VisitorMut>::Break>

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
