ORACLE中文字段排序

做一个2个数据库间数据比较工具时遇到ORACLE中汉字排序的问题。
使用一下SQL

select * 
from T_0303003 
order by stock_holder

进行选取数据时（stock_holder为存放中文的字段），结果发现两库返回的记录顺序不一致。琢磨之后应该为字符集问题，一个库字符集为系统默认字符集，另一个库为UTF-8字符集。查找资料后发现，对于中文字段的排序，应该使用以下方式：

-- 按拼音排序 (系统默认)
select * 
from T_0303003 
order by nlssort(stock_holder,'NLS_SORT=SCHINESE_PINYIN_M');

-- 按部首排序 
select * 
from T_0303003 
order by nlssort(stock_holder,'NLS_SORT=SCHINESE_RADICAL_M');

-- 按笔画排序 
select * 
from T_0303003 
order by nlssort(stock_holder,'NLS_SORT=SCHINESE_STROKE_M');
