Struct DmlStatement

pub struct DmlStatement {
    pub table_name: TableReference,
    pub table_schema: DFSchemaRef,
    pub op: WriteOp,
    pub input: Arc<LogicalPlan>,
    pub output_schema: DFSchemaRef,
}

The operator that modifies the content of a database (adapted from substrait WriteRel)

Fields

table_name: TableReference

The table name

table_schema: DFSchemaRef

The schema of the table (must align with Rel input)

op: WriteOp

The type of operation to perform

input: Arc<LogicalPlan>

The relation that determines the tuples to add/remove/modify the schema must match with table_schema

output_schema: DFSchemaRef

The schema of the output relation

Implementations

impl DmlStatement

pub fn new( table_name: TableReference, table_schema: DFSchemaRef, op: WriteOp, input: Arc<LogicalPlan>, ) -> Self

Creates a new DML statement with the output schema set to a single count column.

pub fn name(&self) -> &str

Return a descriptive name of this DmlStatement

Trait Implementations

impl Clone for DmlStatement

fn clone(&self) -> DmlStatement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DmlStatement

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

Formats the value using the given formatter.

impl Hash for DmlStatement

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

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 PartialEq for DmlStatement

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

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