开始
代码块如下:
BEGIN update emp_cpy set empno=3000 where deptno=20; END;
执行后,再开一个session, 查询:
SQL> select * from emp_cpy where deptno=20; EMPNO ENAME JOB MGR HIREDATE SAL COMM ---------- ---------- --------- ---------- --------- ---------- ---------- DEPTNO ---------- 3000 SMITH CLERK 7902 17-DEC-80 800 20 3000 JONES MANAGER 7839 02-APR-81 2975 20 3000 SCOTT ANALYST 7566 19-APR-87 3000 20 EMPNO ENAME JOB MGR HIREDATE SAL COMM ---------- ---------- --------- ---------- --------- ---------- ---------- DEPTNO ---------- 3000 ADAMS CLERK 7788 23-MAY-87 1100 20 3000 FORD ANALYST 7566 03-DEC-81 3000 20 SQL>
