我以 UserA 身份登录并尝试执行以下操作

alter session set current_schema = UserB;
begin
    execute immediate 'Insert into UserB.tablea (c1, c2) values (val1,val2)'
end;

我不断收到此错误

ORA-01031: insufficient privileges
ORA-06512: at line 3
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.

我确实在 UserA 上有 alter_session 权限，并在 UserB.tablea 上插入权限作为 UserA。有任何想法吗？

您可能对“设置 current_schema = xyz”感到困惑。这只是让您在引用另一个模式中的对象时不必键入用户名，它不会给您任何新的权限。

SQL> select * from scott.dept;

    DEPTNO DNAME          LOC           OPTION
---------- -------------- ------------- --------------------
        10 ACCOUNTING     NEW YORK
        20 RESEARCH       DALLAS
        30 SALES          CHICAGO
        40 OPERATIONS     BOSTON

SQL> select * from dept;
select * from dept
              *
ERROR at line 1:
ORA-00942: table or view does not exist


SQL> alter session set current_schema = scott;

Session altered.

SQL> select * from dept;

    DEPTNO DNAME          LOC           OPTION
---------- -------------- ------------- --------------------
        10 ACCOUNTING     NEW YORK
        20 RESEARCH       DALLAS
        30 SALES          CHICAGO
        40 OPERATIONS     BOSTON

因此，您需要将 UserB.tablea 上的授权插入授予运行代码的用户。作为测试，只需运行

Insert into UserB.tablea (c1, c2) values (val1,val2);

在开始/结束块之外。
