Sql Oracle Create trigger语句失败，内部错误代码为ORA-00600

正在尝试执行从Oracle创建的转储文件。所有内容都会被创建和更改，直到此块：

CREATE OR REPLACE TRIGGER "LABS"."CHANNEL_CHANNEL_ID_TRG" BEFORE INSERT ON channel
FOR EACH ROW
DECLARE 
v_newVal NUMBER(12) := 0;
v_incval NUMBER(12) := 0;
BEGIN
IF INSERTING AND :new.CHANNEL_ID IS NULL THEN
SELECT  channel_CHANNEL_ID_SEQ.NEXTVAL INTO v_newVal FROM DUAL;
-- If this is the first time this table have been inserted into (sequence == 1)
IF v_newVal = 1 THEN 
  --get the max indentity value from the table
  SELECT NVL(max(CHANNEL_ID),0) INTO v_newVal FROM channel;
  v_newVal := v_newVal + 1;
  --set the sequence to that value
  LOOP
       EXIT WHEN v_incval>=v_newVal;
       SELECT channel_CHANNEL_ID_SEQ.nextval INTO v_incval FROM dual;
  END LOOP;
END IF;
--used to emulate LAST_INSERT_ID()
--mysql_utilities.identity := v_newVal; 
-- assign the value from the sequence to emulate the identity column
:new.CHANNEL_ID := v_newVal;
END IF;
END;

这会失败并切断连接，导致以下相当隐晦的错误：

ORA-00603: ORACLE server session terminated by fatal error
ORA-00600: internal error code, arguments: [kqlidchg1], [], [], [], [], [], [], [], [], [], [], []
ORA-00604: error occurred at recursive SQL level 1
ORA-00001: unique constraint (SYS.I_PLSCOPE_SIG_IDENTIFIER$) violated
00603. 00000 -  "ORACLE server session terminated by fatal error"
*Cause:    An ORACLE server session is in an unrecoverable state.
*Action:   Login to ORACLE again so a new server session will be create

---

找到了一个有效的解决方案。用以下ALTER语句围绕代码块：

ALTER SESSION SET PLSCOPE_SETTINGS = 'IDENTIFIERS:NONE';

。。。这里是sql语句

ALTER SESSION SET PLSCOPE_SETTINGS = 'IDENTIFIERS:ALL';

由于某些原因，Oracle数据库转储不包括这些命令，但这解决了问题。

ORA-00600

表示Oracle存在错误，在这种情况下，似乎是导入和PL/Scope之间的交互。在这种情况下，您的变通方法（关闭PL/Scope）很好。如果需要使用PL/Scope，可以重新启用它并重新编译触发器。
