pub trait ForeignKeyDefinitionCatalog {
    // Required methods
    fn resolve_table_reference(&self, name: &str) -> Result<String, SQLError>;
    fn bound_table_name(&self, name: &str) -> Result<Option<String>, SQLError>;

Namespace, key declarations, and REFERENCES checks for one foreign-key declaration.

Required Methods

fn resolve_table_reference(&self, name: &str) -> Result<String, SQLError>

fn bound_table_name(&self, name: &str) -> Result<Option<String>, SQLError>

fn referenceable_keys( &self, table: &str, ) -> Result<Vec<TableKeyConstraint>, ColumnCatalogError>

fn ensure_reference_privilege( &self, table: &str, column: &str, ) -> Result<(), SQLError>
