这是碰到的第一个11.2上的bug，在利用IGNORE_ROW_ON_DUPKEY_INDEX提示执行插入时，很可能碰到这个错误。

测试版本11.2.0.1 for Linux X86-64：

SQL> select * from v$version;

BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE    11.2.0.1.0      Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

建立一个测试表：

SQL> CREATE TABLE T               
  2  (ID NUMBER, 
  3  NAME VARCHAR2(30), 
  4  CONSTRAINT PK_T PRIMARY KEY (ID));

表已创建。

SQL> INSERT INTO T     
  2  VALUES (100, 'TEST');

已创建 1 行。

SQL> COMMIT;

提交完成。

SQL> INSERT INTO T 
  2  SELECT ROWNUM, OBJECT_NAME
  3  FROM DBA_OBJECTS
  4  ;
INSERT INTO T
*
第 1 行出现错误:
ORA-00001: 违反唯一约束条件 (YANGTK.PK_T)

SQL> INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T(ID)) */ 
  2  INTO T
  3  SELECT ROWNUM, OBJECT_NAME
  4  FROM DBA_OBJECTS
  5  ;
INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T(ID)) */
*
第 1 行出现错误:
ORA-00600: 内部错误代码, 参数: [qerltcInsertSelectRop_bad_state], [], [], [], [], [], [], [], [], [], [], []

显然是由于使用IGNORE_ROW_ON_DUPKEY_INDEX提示引起了错误的产生。查询METALINK没有找到任何关于这个错误的描述。这也难怪，比较11.2才出来的时间不长，估计还没有什么人碰到这个bug。不过Oracle的测试人员没有测试到这个新特性的bug不太应该。

在alert文件中，这个错误信息如下：

测试发现，不管IGNORE_ROW_ON_DUPKEY_INDEX的哪种写法，都会引发这个600错误，但是如果插入数据量小的话，可能并不会引发错误：

SQL> INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T(ID)) */ 
  2  INTO T
  3  SELECT ROWNUM, OBJECT_NAME
  4  FROM DBA_OBJECTS
  5  WHERE ROWNUM <= 200;

已创建199行。

SQL> ROLLBACK;

回退已完成。

SQL> INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T(ID)) */ 
  2  INTO T
  3  SELECT ROWNUM, OBJECT_NAME
  4  FROM DBA_OBJECTS
  5  WHERE ROWNUM <= 1000;
INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T(ID)) */
*
第 1 行出现错误:
ORA-00600: 内部错误代码, 参数: [qerltcInsertSelectRop_bad_state], [], [], [], [], [], [], [], [], [], [], []

可以看到，如果插入200条记录，则不会报错。如果插入的数据量达到1000，则会引发ORA-600错误。

进一步测试发现，如果插入行数超过255，就会报错，看来应该是某个变量超过了上限导致的错误。

SQL> INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T, PK_T) */
  2  INTO T 
  3  SELECT * 
  4  FROM T1
  5  WHERE ROWNUM <= 250;

已创建249行。

SQL> INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T, PK_T) */
  2  INTO T
  3  SELECT * 
  4  FROM T1 
  5  WHERE ROWNUM <= 255;

已创建5行。

SQL> INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T, PK_T) */
  2  INTO T
  3  SELECT *
  4  FROM T1
  5  WHERE ROWNUM <= 256;
INSERT /*+ IGNORE_ROW_ON_DUPKEY_INDEX(T, PK_T) */
