怎么把某字段单词的首字母改为大写其它小写？

本文主要是介绍怎么把某字段单词的首字母改为大写其它小写？，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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。

例如有表
id name
1 aBC EFG
2 hij-klm
3 NOPQ

我需要的结果：
id name
1 Abc Efg
2 Hij-Klm
3 Nopq

--> 生成测试数据: @T
DECLARE @T TABLE (id INT,name VARCHAR(50))
INSERT INTO @T
SELECT 1,'aBC EFG' UNION ALL
SELECT 2,'hij-klm' UNION ALL
SELECT 3,'NOPQ'

--SQL查询如下:

;WITH Liang AS
(
   SELECT
        M.id,
        SUBSTRING(M.name,N.number,1) AS s,
        number
   FROM @T AS M
        JOIN master.dbo.spt_values AS N
            ON number BETWEEN 1 AND LEN(M.name)
               AND N.type='p'
)
UPDATE A SET
     name=B.string.value('.','VARCHAR(max)')
FROM @T AS A
   CROSS APPLY (
       SELECT string=(
                  SELECT
                      CASE WHEN number=1 OR
                           (SELECT s
                            FROM Liang
                            WHERE id=T.idAND number=T.number-1) IN(' ','-')
                             THEN UPPER(s)
                          ELSE LOWER(s) END
                 FROM Liang AS T
                 WHERE id=A.id
                 FOR XML PATH(''),TYPE
              )
   ) AS B

SELECT * FROM @t

/*
id          name
----------- --------------------------------------------------
1           Abc Efg
2           Hij-Klm
3           Nopq
