ALTER TABLE statement

Fields

name: ObjectName

Table name

if_exists: bool

Whether IF EXISTS was specified for the ALTER TABLE.

only: bool

Whether the ONLY keyword was used (restrict scope to the named table).

operations: Vec<AlterTableOperation>

List of ALTER TABLE operations to apply.

location: Option<HiveSetLocation>

Optional Hive SET LOCATION clause for the alter operation.

on_cluster: Option<Ident>

ClickHouse dialect supports ON CLUSTER clause for ALTER TABLE For example: ALTER TABLE table_name ON CLUSTER cluster_name ADD COLUMN c UInt32 ClickHouse

table_type: Option<AlterTableType>

Table type: None for regular tables, Some(AlterTableType) for Iceberg or Dynamic tables

end_token: AttachedToken

Token that represents the end of the statement (semicolon or EOF)

Trait Implementations

impl Clone for AlterTable

fn clone(&self) -> AlterTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlterTable

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

Formats the value using the given formatter.

impl Display for AlterTable

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

Formats the value using the given formatter.

impl From<AlterTable> for Statement

fn from(at: AlterTable) -> Statement

Converts to this type from the input type.

impl Hash for AlterTable

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 AlterTable

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

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

fn partial_cmp(&self, other: &AlterTable) -> 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 AlterTable

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 Eq for AlterTable

impl StructuralPartialEq for AlterTable
