PL/SQL: ORA-00942: table or view does not exist

在用户jytest下可以直接查询jytest1.test表但是在jytest下创建一个过程，在过程中引用jytest1.test表编译不通过.在过程中引用别的

有两个用户jytest,jytest1都拥有dba权限在jytest1用户创建了一个表test

create user jytest identified by “jytest”

default tablespace users temporary tablespace temp;

grant dba to jytest;

grant resource to jytest;

grant connect to jytest;

create user jytest1 identified by “jytest1”

default tablespace users temporary tablespace temp;

grant dba to jytest1;

grant resource to jytest1;

grant connect to jytest1;

create table jytest1.test(userid number(20));

SQL> select a.owner,a.object_name,a.object_type from dba_objects a where a.object_id=52603;

OWNER OBJECT_NAME OBJECT_TYPE

JYTEST1 TEST TABLE

在用户jytest下可以直接查询jytest1.test表但是在jytest下创建一个过程，在过程中引用jytest1.test表编译不通过.在过程中引用别的用户对象不能通过role权限来访问,要通过对象授权才能在过程中访问

SQL> alter session set events ‘10046 trace name context forever,level 12’;

Session altered

SQL> select * from jytest1.test;

USERID———————

SQL> alter session set events ‘10046 trace name context off’;

Session altered

它的跟踪文件中显示的记录部分信息如下:select col#, grantee#, privilege#,max(mod(nvl(option$,0),2)) from objauth$ where obj#=:1 and col# is not null group by privilege#, col#, grantee# order by col#, grantee#END OF STMTPARSE #2:c=0,e=86,p=0,cr=0,cu=0,mis=0,r=0,dep=1,og=4,tim=1355777810000085BINDS #2:kkscoacd Bind#0

kxsbbbfp=b7f47498 bln=22 avl=04 flg=05

value=52603上面的操作显示了用户jytest在执行select * from jytest1.test查询时会查询jytest用户对jytest1.test表是否有select权限

select con#,obj#,rcon#,enabled,nvl(defer,0) from cdef$ where robj#=:1END OF STMTPARSE #4:c=0,e=55,p=0,cr=0,cu=0,mis=0,r=0,dep=1,og=4,tim=1355777810001339BINDS #4:kkscoacd Bind#0
