Implementation

@override
Future<Set<String>> indexFields(String indexName) async {
  String sql = "SELECT * FROM INFORMATION_SCHEMA.STATISTICS WHERE TABLE_SCHEMA = ? AND TABLE_NAME = ? AND INDEX_NAME = ?";
  QueryResult r = await execute(sql, [schema!, tableName, indexName]);
  return r.listValues<String>("COLUMN_NAME").toSet();
}
