我目前正處於一個需要我編寫SQL腳本以創建本地數據庫的項目中。在我的代碼中，我創建了一個數據庫鏈接到我創建用戶需要的開發數據庫。爲了讓我通過所有單元測試，我需要提供從我的數據庫鏈接訪問所需的特定表。當我運行所有單元測試時，唯一拋出的錯誤是'ORA-00942：表或視圖不存在'。我如何從本地數據庫鏈接爲用戶xxltbpg授予對這些表的訪問權限？授予對從數據庫鏈接到本地數據庫的表的訪問權
下面是我迄今編寫的代碼：
--Drop Database--
drop database link DEV_LINK;
--Create database link--
create database link DEV_LINK
connect to XXLT

using '(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = usnoebsdev64db) (PORT = 1531))(CONNECT_DATA = (SID = DEV))) ';
--Create Users for LWS-
