SqlServer 获取字符串中小写字母的sql语句

这样我们就获取到了小写字母，当然我们还可以获取大写字母：

SELECT @temp=@temp+SUBSTRING(ch, sv.number, 1)  
FROM  (SELECT @s AS ch) t 
    CROSS APPLY [master].dbo.spt_values AS sv  
WHERE sv.type = ‘P‘ 
    AND sv.number BETWEEN 1 AND LEN(ch)  
    AND ASCII(SUBSTRING(ch, sv.number, 1)) BETWEEN ASCII(‘A‘) AND ASCII(‘Z‘)  
SELECT @temp
