Struct RemoteTableRef

pub struct RemoteTableRef {
    pub table_ref: TableReference,
    pub args: Option<Arc<[FunctionArg]>>,
}

A multipart identifier to a remote table, view or parameterized view.

RemoteTableRef can be created by parsing from a string representing a table object with optional

use datafusion_federation::sql::RemoteTableRef;
use datafusion::sql::sqlparser::dialect::PostgreSqlDialect;

RemoteTableRef::try_from("myschema.table");
RemoteTableRef::try_from(r#"myschema."Table""#);
RemoteTableRef::try_from("myschema.view('obj')");

RemoteTableRef::parse_with_dialect("myschema.view(name = 'obj')", &PostgreSqlDialect {});

Fields

table_ref: TableReference

args: Option<Arc<[FunctionArg]>>

Implementations

impl RemoteTableRef

pub fn to_quoted_string(&self) -> String

Get quoted_string representation for the table it is referencing, this is same as calling to_quoted_string on the inner table reference.

pub fn parse_with_default_dialect(s: &str) -> Result<Self, DataFusionError>

Create new using general purpose dialect. Prefer Self::parse_with_dialect if the dialect is known beforehand

pub fn parse_with_dialect( s: &str, dialect: &dyn Dialect, ) -> Result<Self, DataFusionError>

Create new using a specific instance of dialect.

pub fn table_ref(&self) -> &TableReference

pub fn args(&self) -> Option<&[FunctionArg]>

Trait Implementations

impl Clone for RemoteTableRef

fn clone(&self) -> RemoteTableRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RemoteTableRef

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

Formats the value using the given formatter.

impl From<&RemoteTableRef> for TableReference

fn from(remote_table_ref: &RemoteTableRef) -> Self

Converts to this type from the input type.

impl From<(TableReference, Vec<FunctionArg>)> for RemoteTableRef

fn from((table_ref, args): (TableReference, Vec<FunctionArg>)) -> Self

Converts to this type from the input type.

impl From<RemoteTableRef> for TableReference

fn from(remote_table_ref: RemoteTableRef) -> Self

Converts to this type from the input type.

impl From<TableReference> for RemoteTableRef

fn from(table_ref: TableReference) -> Self

Converts to this type from the input type.

impl Hash for RemoteTableRef

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 RemoteTableRef

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

type Error = DataFusionError

The type returned in the event of a conversion error.

fn try_from(s: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for RemoteTableRef

type Error = DataFusionError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for RemoteTableRef

type Error = DataFusionError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.
