在Oracle定义变量�Ӟ��常有VARCHAR2 (3 Char)或者VARCHAR2 (10 Byte)的数据类型，那么3char或�?0Byte到底代表几个汉字�Q�几个字�W�呢�Q�上�ơ外公司一同事讨论�q�个问题�Q�一下没�l�解释清楚，所以下来以后整理如下：(x��)

�ȝ��Q?br /> 当NLS_CHARACTERSET=AL32UTF8�Ӟ��Q?br /> NLS_LENGTH_SEMANTICS=BYTE�Ӟ��一个汉字代表三个字�?br /> NLS_LENGTH_SEMANTICS=CHAR�Ӟ��一个汉字代表一个字�?br /> 当NLS_CHARACTERSET=US7ASCII�Ӟ��字符集�ؓ(f��)单字节）(j��)
NLS_LENGTH_SEMANTICS=BYTE�Ӟ��一个汉字代表两个字�?br /> NLS_LENGTH_SEMANTICS=CHAR�Ӟ��一个汉字代表两个字�?/p>

---------- ---- -------- ----------- ---------

NLS_BYTE C1 VARCHAR2 7 B

NLS_LENGTH_SEMANTICS allows you to specify the length of a column datatype in terms of CHARacters rather than in terms of BYTEs. Typically this is when using an AL32UTF8 or other varying width NLS_CHARACTERSET database where one character is not always one byte. While using CHAR semantics has as such no added value in a 7/8 bit characterset it's fully supported so any application code / table setup using CHAR can also be used in a 7/8bit characterset like US7ASCII/WE8MSWIN1252.
This parameter is a 9i (and up) feature and is not available in older releases

��译�q�来��是:�q�个参数允许��列的数据单位设为字�W�而不是byte.�q�个问题�?x��)在字符集设为UTF8的时候出�? 此参数在9i以上版本有效.

NLS_LENGTH_SEMANTICS 讄��.

1. NLS_DATABASE_PARAMETERS中的值是在数据库创徏的时候确定的,一般都为BYTE

2. 此参数可以以 “ALTER SYSTEM SET NLS_LENGTH_SEMANTICS=CHAR scope=both”方式修改,但是需要重启数据库才能生效.

3. 也可�?#8221; ALTER SESSION SET NLS_LENGTH_SEMANTICS=CHAR”使对当前session生效.

4. 此参数可以在10G以上版本�?在环境变量或注册表中讄��(注意需要大�?,讑֮�后从当前客户端启动的所有会(x��)话都采用新的取�?

5. 修改后只�Ҏ(gu��)��建的列生�?对于已有的列没有作用

6. 新徏或升�U�DB时用BYTE,否则XDB或dba_tables�?x��)出现问�?

7. NLS_LENGTH_SEMANTICS对sys用户下的对象无效.

8. 如果对于7/8bit的字�W�集,设�ؓ(f��)byte/char意义不大,因�ؓ(f��)无论是char和byte都对应一个byte.

��试:

一.在当前session中修�Ҏ(gu��)��参数

SQL> alter session set nls_length_semantics='char';

Session altered

SQL> create table nls_char(c1 varchar2(7),c2 varchar2(7));

2. Alter table

Bug-3611750, ora-01450 online rebuild of index fails, 可以在重建烦(ch��)引前指定byte, 10.2.0.5以上已经修复
