权限不足

大家好,又见面了,我是全栈君。

例如以下一个存储过程是dba创建一个表空间、创建一个用户并给这个用户授予权限:

create or replace procedure createTS(tname in varchar2)

is PRAGMA AUTONOMOUS_TRANSACTION; v_createsql varchar2(400); vtbsname varchar2(40); begin vtbsname := tname; v_createsql:=’CREATE TABLESPACE ‘|| vtbsname ||’ DATAFILE ”F:\APP\ADMINISTRATOR\ORADATA\’|| vtbsname ||’.dbf” SIZE 30M AUTOEXTEND ON NEXT 10M’; Dbms_Output.Put_Line(v_createsql); execute immediate v_createsql; v_createsql:=’CREATE USER ‘|| vtbsname ||’ identified by ‘|| vtbsname ||’ default tablespace ‘||vtbsname; Dbms_Output.Put_Line(v_createsql); execute immediate v_createsql; — v_createsql:=’grant ALTER SESSION,CREATE CLUSTER,CREATE DATABASE LINK,CREATE SEQUENCE,CREATE SESSION ,CREATE SYNONYM,CREATE VIEW to ‘|| vtbsname; — v_createsql:=’GRANT CREATE SESSION,CREATE CLUSTER,CREATE INDEXTYPE,CREATE OPERATOR,CREATE PROCEDURE,CREATE SEQUENCE,CREATE TABLE,CREATE TRIGGER,CREATE TYPE,INSERT ANY TABLE,UPDATE ANY TABLE,SELECT ANY TABLE,DELETE ANY TABLE to ‘|| vtbsname; v_createsql:=’GRANT connect,resource to ‘|| vtbsname; Dbms_Output.Put_Line(v_createsql); execute immediate v_createsql;

end createTS;

PROCEDURE CREATETS 已编译

编译通过,例如以下运行

set serveroutput on; execute createTS(‘nk_develop14061342’);

在行 28 上開始运行命令时出错: execute createTS(‘nk_develop14061343’) 错误报告: ORA-01031: 权限不足 ORA-06512: 在 “NK_DEVELOP131021.CREATETS”, line 22 ORA-06512: 在 line 1 01031. 00000 – “insufficient privileges” *Cause: An attempt was made to change the current username or password without the appropriate privilege. This error also occurs if attempting to install a database without the necessary operating system privileges. When Trusted Oracle is configure in DBMS MAC, this error may occur if the user was granted the necessary privilege at a higher label than the current login. *Action: Ask the database administrator to perform the operation or grant the required privileges. For Trusted Oracle users getting this error although granted the the appropriate privilege at a higher label, ask the database administrator to regrant the privilege at the appropriate label. CREATE TABLESPACE nk_develop14061343 DATAFILE ‘F:\APP\ADMINISTRATOR\ORADATA\nk_develop14061343.dbf’ SIZE 30M AUTOEXTEND ON NEXT 10M CREATE USER nk_develop14061343 identified by nk_develop14061343 default tablespace nk_develop14061343 GRANT connect,resource to nk_develop14061343

原因是在运行授予权限之时因为权限不足造成的

找到一个帖子例如以下:http://bbs.csdn.net/topics/360053754

最终找到毛病了,原来是没有权限。尽管当前用户运行语句是有权限的,可是放到存储过程中就必需要显式的赋个权限给当前用户。下面是我找到的资料,贴出来给大家也看一下吧。 ===================== 【IT168 技术文档】我们知道,用户拥有的role权限在存储过程是不可用的。如:

SQL> select * from dba_role_privs where grantee=’SUK’;

GRANTEE GRANTED_ROLE ADMIN_OPTION DEFAULT_ROLE ———— ———— ———— ———— SUK DBA NO YES SUK CONNECT NO YES SUK RESOURCE NO YES

–用户SUK拥有DBA这个role –再创建一个測试存储过程: create or replace procedure p_create_table is begin Execute Immediate ‘create table create_table(id int)’; end p_create_table;

–然后測试 SQL> exec p_create_table;

begin p_create_table; end;

ORA-01031: 权限不足 ORA-06512: 在”SUK.P_CREATE_TABLE”, line 3 ORA-06512: 在line 1

–能够看到。即使拥有DBA role。也不能创建表。role在存储过程中不可用。

–遇到这样的情况,我们一般须要显式进行系统权限。如grant create table to suk; –但这样的方法太麻烦,有时候可能须要进行许多的授权才干运行存储过程 –实际上,oracle给我们提供了在存储过程中使用role权限的方法: –改动存储过程,增加Authid Current_User时存储过程能够使用role权限。 create or replace procedure p_create_table Authid Current_User is begin Execute Immediate ‘create table create_table(id int)’; end p_create_table;

–再尝试运行: SQL> exec p_create_table;

PL/SQL procedure successfully completed

–已经能够运行了。

原来 是要使用调用者权限

因此在创建存储过程时须要增加Authid Current_User当前用户的权限

create or replace procedure createTS(tname in varchar2) Authid Current_User is

要在存储过程里动态创建创建表空间例如以下步骤。 1、须要採用Oracle自治事务

就在存储过程里增加PRAGMA AUTONOMOUS_TRANSACTION;子句 2、须要显示的分配置创建表空间的权限,否则提示权限不足。 grant alter tablespace to TEST; grant create tablespace to TEST;
