在oracle9i中新增了按照拼音、部首、笔画排序功能。设置NLS_SORT值
SCHINESE_RADICAL_M 按照部首(第一顺序)、笔划(第二顺序)排序
SCHINESE_STROKE_M 按照笔划(第一顺序)、部首(第二顺序)排序
SCHINESE_PINYIN_M 按照拼音排序
oracle9i中新增了按照拼音、部首、笔画排序功能
用法示例:
- 拼音
- SELECT * FROM TEAM ORDER BY NLSSORT(排序字段,'NLS_SORT = SCHINESE_PINYIN_M')
- 笔划
- SELECT * FROM TEAM ORDER BY NLSSORT(排序字段,'NLS_SORT = SCHINESE_STROKE_M')
- 部首
- SELECT * FROM TEAM ORDER BY NLSSORT(排序字段,'NLS_SORT = SCHINESE_RADICAL_M')
2 按首字母拼音查询
首先我们要创建一个可以查询汉字首字母的函数,函数代码如下:
