Represents a path to a table that may require further resolution

Variants

Bare

Fields

table: &'a str

The table name

An unqualified table reference, e.g. “table”

Partial

Fields

schema: &'a str

The schema containing the table

table: &'a str

The table name

A partially resolved table reference, e.g. “schema.table”

Full

Fields

catalog: &'a str

The catalog (aka database) containing the table

schema: &'a str

The schema containing the table

table: &'a str

The table name

Implementations

impl<'a> TableReference<'a>

pub fn table(&self) -> &str

Retrieve the actual table name, regardless of qualification

pub fn resolve(
    self,
    default_catalog: &'a str,
    default_schema: &'a str
) -> ResolvedTableReference<'a>

Given a default catalog and schema, ensure this table reference is fully resolved

Trait Implementations

fn from(s: &'a str) -> Self

Converts to this type from the input type.

impl<'a> From<ResolvedTableReference<'a>> for TableReference<'a>

fn from(resolved: ResolvedTableReference<'a>) -> Self
