二、MOS记录

ERROR:              
  ORA-600 [4194] [a] [b]
 
VERSIONS:           
  versions 6.0 to 10.1 

DESCRIPTION:

  A mismatch has been detected between Redo records and rollback (Undo) 
  records.

  We are validating the Undo record number relating to the change being 
  applied against the maximum undo record number recorded in the undo block.

  This error is reported when the validation fails.

ARGUMENTS:
  Arg [a] Maximum Undo record number in Undo block
  Arg [b] Undo record number from Redo block

三、解决办法
1、修改参数
undo_management= MANUAL
undo_tablespace= SYSTEM
2、打开数据库，删除当前undo空间，重建新undo空间
3、修改参数
undo_management= AUTO
undo_tablespace= UNDOTBSNEW
4、重新启动数据库

本篇只讨论in/exists和not in/not exists语意，不涉及这些写法的执行效率问题，至于效率问题请见:in/exists和not in/not exists执行效率
1、准备实验环境

提交完成。

SQL> select * from t1;

        C1         C2
---------- ----------
         1          2
         1          3
         1

SQL> select * from t2;

        C1         C2
---------- ----------
         1          2
         1

Note:t1和t2表都有null，且t1比t2多一条记录

2、t2做内部表

SQL> select * from t1 where c2 in (select c2 from t2 );

        C1         C2
---------- ----------
         1          2

SQL> select * from t1 where exists (select c2 from t2 where t1.c2=t2.c2);

        C1         C2
---------- ----------
         1          2

SQL> select * from t1 where c2 not in (select c2 from t2 );

未选定行

SQL> select * from t1 where not exists (select 1 from t2 where t1.c2=t2.c2);

        C1         C2
---------- ----------
         1          3
         1

3、t1为内部表

SQL> select * from t2 where c2 in (select c2 from t1 );

        C1         C2
---------- ----------
         1          2

SQL> select * from t2 where exists (select c2 from t1 where t1.c2=t2.c2);

        C1         C2
---------- ----------
         1          2

SQL> select * from t2 where c2 not in (select c2 from t1 );

未选定行

SQL> select * from t2 where not exists (select 1 from t1 where t1.c2=t2.c2);

        C1         C2
---------- ----------
         1

3、结论
in和exists结果相同(都会排除掉null,无论内部表中有无null)
not in会过滤掉外部表中的null(即使内部表中无null)
not exists不会过滤掉外部表的null(即使内部表有null)
