使用工具Sql Navigator 6.2.1时出错： 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是表格 当我运行select命令时没有错误，单击表名称显示Sql Navigator中的表的属性无操作。
但我在Oracle Sql开发人员（同一用户）中运行以上命令结果没有错误并显示描述字段。
是什么原因？

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包的权利。

desc命令不是SQL标准。 desc是sqlplus命令。
SQL Developer运行一个大的SQL查询和sql navigator一个简单的SQL查询。
SQLNavigator®forOracle V6.2.1不支持ORACLE 11.2版。
SQLNavigator®forOracle V 6.2.1发行说明2009年9月发行说明。
Oracle Database 11g第2版（11.2.0.1）2010年4月2日
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。
