oracle数据库创建触发器错误

[Myjust_Nico]

求助各位高人解答，触发器如下：
Create or replace Trigger trigger_NewStudent
after insert
on t_welcome_student
begin
insert into t_xsjbxx_jbxx(xh,xm,xznj,sfbs,sfzjlxm,sfzjh,xbdm,yxsh,zydm,xsbh,sfzj,sfzx,xslbdm)
select CID,NAME,GRADE,'0','01',IDCARD,(case sexname when '男' then '1' else '2'end),deptcode,specid,
(dbms_random.string('l',8)||'-8c45-11e0-8a9a-67da650471f5'),'01','01',
(case studyyears when '4'then '01'else '02'end)
from t_welcome_student
where CID not in (select xh from t_xsjbxx_jbxx);
dbms_output.put_line("4")
end trigger_NewStudent;
commit;
错误：ORA-04098:trigger 'USR_CES.TRIGGER_NEWSTUDENT' is invalid and failed re-validation

commit;
触发器里不用commit;

你将commit去掉试试，因为触发器中是不允许有：commit ,rollback.等事务控制语句在里面的。
触发器也是过程级原子性,也就是说当主体语句执行失败时,触发器也会失败;

--commit在触发器外，不是触发器一部分，没问题的，不过是多余的
CREATE OR REPLACE TRIGGER trigger_NewStudent
  AFTER INSERT ON t_welcome_student
  FOR EACH ROW --如果是行级触发器加上这一行,否则为语句级触发器
BEGIN
  --如果引用t_welcome_student表的当前字段值,加上:new.
  INSERT INTO t_xsjbxx_jbxx
    (xh,
     xm,
     xznj,
     sfbs,
     sfzjlxm,
     sfzjh,
     xbdm,
     yxsh,
     zydm,
     xsbh,
     sfzj,
     sfzx,
     xslbdm)
    SELECT :new.CID,
           :new.NAME,
           :new.GRADE,
           '0',
           '01',
           :new.IDCARD,
           (CASE :new.sexname
             WHEN '男' THEN
              '1'
             ELSE
              '2'
           END),
           :new.deptcode,
           :new.specid,
           (dbms_random.string('l', 8) || '-8c45-11e0-8a9a-67da650471f5'),
           '01',
           '01',
           (CASE :new.studyyears
             WHEN '4' THEN
              '01'
             ELSE
              '02'
           END)
      FROM t_welcome_student
     WHERE :new.CID NOT IN (SELECT xh FROM t_xsjbxx_jbxx);
  dbms_output.put_line('4'); --这是输出'4'字符串应该是单引号,语句结束少了分号
END trigger_NewStudent;

触发器 end； /就ok了吧
