在9i 之前,對於中文oracle是用二進制進行排序的(binary)

在9i中新增了拼音,部首,筆劃排序.

SCHINESE_RADICAL_M 按照部首(第一順序)、筆劃(第二順序) 排序

SCHINESE_STROKE_M 按照筆劃(第一順序)、部首(第二順序)排序

SCHINESE_PINYIN_M 按照拼音排序[@more@]

-- 當前session的排序方式
SYS@HUIYI>select * from nls_session_parameters where parameter like 'NLS_SORT%';

PARAMETER  VALUE
---------- ------------------------------
NLS_SORT   BINARY

SYS@HUIYI>select gen01,gen02,dump(gen02) gen022 from gen order by gen02;
