存储过程执行无效

[JS]

需求很简单，我想把system用户下与test用户共有的表删除，但是存储过程执行后并没有删除，也没报错，不知道是什么问题，请大神看看
create or replace procedure dr_table is 
cursor c1 is 
select 'drop table '||table_name||' cascade constraints' v_name from all_tables a where owner='SYSTEM' and 
exists(select table_name from all_tables b where owner='TEST' and a.TABLE_NAME=b.TABLE_NAME);
sqlstr varchar2(1000);
begin
  for i in c1 loop
    sqlstr:=i.v_name;
    --dbms_output.put_line(sqlstr);
    execute immediate sqlstr;
  end loop;
end;

-- dba用户执行
create or replace procedure dr_table is 
cursor c1 is 
select table_name from all_tables a where owner='SYSTEM' and 
exists(select table_name from all_tables b where owner='TEST' and a.TABLE_NAME=b.TABLE_NAME);
sqlstr varchar2(1000);
begin
  for i in c1 loop
    sqlstr:='drop table SYSTEM.'||i.table_name||' cascade constraints';
    execute immediate sqlstr;
    sqlstr:='drop table TEST.'||i.table_name||' cascade constraints';
    execute immediate sqlstr;
  end loop;
end;

引用 1 楼 jascjasc 的回复:

-- dba用户执行
create or replace procedure dr_table is 
cursor c1 is 
select table_name from all_tables a where owner='SYSTEM' and 
exists(select table_name from all_tables b where owner='TEST' and a.TABLE_NAME=b.TABLE_NAME);
sqlstr varchar2(1000);
begin
  for i in c1 loop
    sqlstr:='drop table SYSTEM.'||i.table_name||' cascade constraints';
    execute immediate sqlstr;
    sqlstr:='drop table TEST.'||i.table_name||' cascade constraints';
    execute immediate sqlstr;
  end loop;
end;

上面理解可能有误，下面的是只删除system用户下的重复表

-- system用户登录
create or replace procedure dr_table is 
cursor c1 is 
select table_name from all_tables a where owner='SYSTEM' and 
exists(select table_name from all_tables b where owner='TEST' and a.TABLE_NAME=b.TABLE_NAME);
sqlstr varchar2(1000);
begin
  for i in c1 loop
    sqlstr:='drop table '||i.table_name||' cascade constraints';
    execute immediate sqlstr;
  end loop;
end;

sqlstr:='drop table SYSTEM.'||i.table_name||' cascade constraints';

不行，还是不能删除，但是存储过程没有错误啊，不知道是什么问题。

一般加个exception捕获异常。先看看select from all_tables where exists有没有找到数据。

已经解决了，过程没有问题，问题是赋予了select any table权限
