使用工具 Sql Navigator 6.2.1 时出现错误：我在 Sql Navigator 中运行命令它警告错误：“ORA-01031：权限不足 ORA-06512：在“SYS.DBMS_UTILITY”，第 140 行 ORA-06512：第 6 行“
desc com.zsdddept;
com.zsdddept 是表，当我运行 select 命令时它没有错误，然后单击表名在 Sql Navigator 中显示表的属性无操作。
但我在 Oracle Sql 开发人员（同一用户）中运行上述命令，结果没有错误并显示描述字段。
什么原因？
谢谢
SQL Navigator 执行 SQL * Plus 命令的自定义 SQL 模拟。SQL Developer 您自己的自定义 SQL 模拟 SQL * Plus 命令。授予执行 SYS.DBMS_UTILITY 包的权限。
grant execute on SYS.DBMS_UTILITY to <username>;

该desc命令不是 SQL 标准。desc是 sqlplus 命令。SQL Developer 运行一个大的 sql 查询，而 sql navigator 运行一个简单的 sql 查询。SQL Navigator® for Oracle 版本 6.2.1 不支持 ORACLE 版本 11.2。

您需要购买并安装最新版本的 SQL Navigator 或使用免费版本的 sqlplus 或 Oracle SQL Developer。
