使用 Sql 导航器时出错

Question

我在使用工具 Sql Navigator 6.2.1 时出错：我在运行 Navigator 中的运行命令提示错误：“ORA-01031: 权限不足 ORA-06512: 在 "SYS.DBMS_UTILITY"，第 140 行 ORA-06512: 在第 6 行

desc com.zsdddept;

com.zsdddept 是 table 当我运行 select 命令没有错误并单击 table name 在 Sql Navigator no action 中显示 table 的属性时。

但是我运行在 Oracle Sql 开发人员（同一用户）中的上述命令结果没有错误并显示描述字段。

这是什么原因？

谢谢

Answer 1

SQL Navigator 执行其对 SQL * Plus 命令的自定义 SQL 仿真。 SQL 开发您自己的自定义 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>;

示例 1 desc DEPT 运行 SQLNavigator 6.7

select /*+ ALL_ROWS */ column_name,data_type,nullable,data_length,NVL(data_precision,-99),NVL(data_scale,-99),char_used, char_length 
 from sys.all_tab_columns where owner='SCOTT' and table_name='DEPT' order by column_id

Name                           Data Type                     
------------------------------ ------------------------------

DEPTNO NOT NULL NUMBER(2)

在sql缓存中，这是过程调用。

       l_schema      varchar2(128);
       l_part1       varchar2(128);
       l_part2       varchar2(128);

       l_part1_type  number;
       l_objid       number;
    begin
     DBMS_UTILITY.NAME_RESOLVE ( 
       name          => :obj_name, 
       context       => 2,  -- interested in dba_ views only; 0 doesn't work in 10g -- bug 19528375

       object_number => l_objid );
    end;

inv_restricted_object异常； pragma exception_init(inv_restricted_object, -24239);

在SYS.DBMS_UTILITY

中处理异常时注释第140行

 /*
   * Option flags supported by invalidate.
   *   inv_error_on_restrictions - The invalidate routine imposes various
   *   restrictions on the objects that can be invalidated. For example,
   *   the object specified by p_object_id cannot be a table. By default,

Answer 2

desc 命令不是 SQL 标准。 desc 是 sqlplus 命令。 SQL 开发人员运行一个大的 sql 查询，sql 导航器运行一个简单的 sql 查询。 SQL Navigator® for Oracle 版本 6.2.1 不支持 ORACLE 版本 11.2。

SQL Navigator® for Oracle 版本 6.2.1 发行说明 2009 年 9 月发行说明。

Oracle 数据库 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。
