怎么把某字段单词的首字母改为大写其它小写？

Question

要改某字段的内容，要求改为大写的情况：
1、字段首字母
2、空格后的首字母
3、“-”后的首字母
其它都改为小写。

Answer 1

UPPER
返回将小写字符数据转换为大写的字符表达式。语法
UPPER ( character_expression )参数
character_expression由字符数据组成的表达式。character_expression 可以是常量、变量，也可以是字符或二进制数据的列。返回类型
varchar注释
character_expression 必须为可隐性转换为 varchar 的数据类型。否则请使用 CAST 函数显式转换 character_expression。示例
本示例使用 UPPER 函数和 RTRIM 函数来返回整理过的大写的作者姓名。USE pubs
GO
SELECT UPPER(RTRIM(au_lname)) + ', ' + au_fname AS Name
FROM authors
ORDER BY au_lname
GO下面是结果集：Name

Answer 2

UPPER()函數
用法 樓上的大烏龜已經講的很清楚了.

Answer 3

例如有表
id    name
1     aBC EFG
2     hij-klm
3     NOPQ我需要的结果：

3     Nopq谢谢

Answer 4

要我处理就引出到excel,处理完后再引入,再update,用SQL直接更新,有点麻烦

Answer 5

--前提,每条记录只有一个' ' 或'-'或没有.如果有多个,就自己写函数慢慢分析了.create table tb(id int, name varchar(10))
insert into tb values(1 ,   'aBC EFG') 
insert into tb values(2 ,   'hij-klm') 
insert into tb values(3 ,   'NOPQ')
goselect id , name = upper(left(name , 1)) + lower(substring(name,2,len(name))) from tb where charindex(' ' , name) = 0 and charindex('-' , name) = 0
union all
select id , name = upper(left(name , 1)) + lower(substring(name,2,charindex(' ',name) - 1)) + upper(substring(name,charindex(' ',name) + 1,1)) from tb where charindex(' ' , name) > 0 and len(name) = charindex(' ',name) + 1
union all
select id , name = upper(left(name , 1)) + lower(substring(name,2,charindex(' ',name) - 1)) + upper(substring(name,charindex(' ',name) + 1,1)) + lower(substring(name,charindex(' ',name) + 2,len(name))) from tb where charindex(' ' , name) > 0 and len(name) > charindex(' ',name) + 1
union all
select id , name = upper(left(name , 1)) + lower(substring(name,2,charindex('-',name) - 1)) + upper(substring(name,charindex('-',name) + 1,1)) from tb where charindex('-' , name) > 0 and len(name) = charindex('-',name) + 1
union all
select id , name = upper(left(name , 1)) + lower(substring(name,2,charindex('-',name) - 1)) + upper(substring(name,charindex('-',name) + 1,1)) + lower(substring(name,charindex('-',name) + 2,len(name))) from tb where charindex('-' , name) > 0 and len(name) > charindex('-',name) + 1
order by iddrop table tb /*

Answer 8

看LZ的架势，那个“某个字段”里应该是一篇文章？？ 
字段类型是 text/ntext  吧 ?
