Question

使用我创建的用户连接到数据库时遇到一些问题。首先，我创建了这样的用户：

create user util1 identified by user1;

create user util2 identified by user2;

create user util3 identified by user3;

create user util4 identified by user4;

create user util5 identified by user5;

create user util6 identified by user6;

create user util7 identified by user7;

create user util8 identified by user8;

grant dba to util1,util2,util3,util4,util5,util6,util7,util8;

select lpad(' ', 2*level) || granted_role "User, his roles and privileges"
   from (select null grantee, username granted_role from dba_users where username like upper('%UTIL%')
         union
            select grantee, granted_role from dba_role_privs
         union
            select grantee, privilege from dba_sys_privs)
                                           start with grantee is null
                                           connect by grantee = prior granted_role;

这工作正常。但是当我尝试使用“util1”的权限创建一个表时，它不起作用：

connect util1/user1 AS SYSDBA;
create table pr1(
             cod_subansamblu number(4),
             denumire varchar2(20) not null,
             cantitate number(7,3),
             UM varchar2(3),
             pret_unitar number(9,2),
             cod_ansamblu number(4),
             cod_sectie number(4)  not null,
             constraint pr1_cod_subansamblu_pk primary key(cod_subansamblu),
             constraint pr1_UM_chk check(UM in ('BUC','ML','MP','MC','SET'))
             );

我真的不知道出了什么问题。非常感谢帮助。

我收到的错误消息是：

Last Execution Details

ORA-00900: invalid SQL statement

CREATE TABLE语句没有错：

SQL> create table pr1(
             cod_subansamblu number(4),
             denumire varchar2(20) not null,
             cantitate number(7,3),
             UM varchar2(3),
             pret_unitar number(9,2),
             cod_ansamblu number(4),
             cod_sectie number(4)  not null,
             constraint pr1_cod_subansamblu_pk primary key(cod_subansamblu),
             constraint pr1_UM_chk check(UM in ('BUC','ML','MP','MC','SET'))
             );  2    3    4    5    6    7    8    9   10   11  

Table created.

因此很难理解为什么它在运行时会抛出ORA-00900。你用什么客户来运行它？在SQL * Plus？像TOAD一样的IDE？你能提供一个完整会话的cut'n'paste所以我们可以看到完全发生了什么？

要记住的另一件事是，如果使用as sysdba进行连接，则无论是否在CONNECT字符串中指定用户，都以SYS身份登录数据库：

SQL> conn apc/password as sysdba
Connected.
SQL> sho user
USER is "SYS"
SQL>

（仅当您以oracle帐户或其他适当特权用户身份登录操作系统时才有效。

因此，您可能认为您正在将您的create table语句作为UTIL1运行，但实际上您将其作为SYS运行，这不是一个好主意。事实上，这是不好的做法。
