GaussDB(DWS)中可以使用Database和Schema实现业务的隔离,区别在于:Database之间无法直接互访,通过连接隔离实现彻底的权限隔离。各个Database之间共享资源极少,可实现连接隔离、权限隔离等。Schema隔离的方式共用资源较多,可以通过GRANT与REVOKE语法便捷地控制不同用户
Web端使用导入sql功能是默认使用public schema,会报错ERROR: permission denied for schema public 1、在web端点击数据库名字跳转到schema列表,新增schema; 2、sql文件最开始增加 set current_schema = 创建的schema; #3、数据源配置 如下方案二选一即可。
schema实现了对业务的逻辑划分,反过来这些业务对象也对schema形成一种依赖关系,因此当schema下存在对象时,删除schema的时候会报错,并提示具体的依赖信息。 postgres=#--删除失败,提示依赖关系 postgres=#DROPSCHEMAnsp_1;ERROR:cannot drop schema nsp_1 because other objects depend on itDETAIL:table nsp_1....
