pub fn statement_table_name(statement: &PlanStatement) -> Option<&str>Expand description
Return the table name referenced by a plan statement, if any.
This is a small helper used by higher-level engines (for example the
SQL front-end) to provide better error messages when a statement fails
with a table-related error. It intentionally returns an Option<&str> so
callers can decide how to report missing table context.
