--  @testpoint:opengauss关键字Hierarchy(非保留)，作为外部数据源名

--关键字不带引号-成功
drop data source if exists Hierarchy;
create data source Hierarchy;
drop data source Hierarchy;

--关键字带双引号-成功
drop data source if exists "Hierarchy";
create data source "Hierarchy";
drop data source "Hierarchy";

--关键字带单引号-合理报错
drop data source if exists 'Hierarchy';
create data source 'Hierarchy';

--关键字带反引号-合理报错
drop data source if exists `Hierarchy`;
create data source `Hierarchy`;
