代码如下:

eclare @str nvarchar(50);

set @str='462,464,2';

select @str as '字符串'

select len(@str) as '字符长度'

select charindex(',',@str,1) as '第一个逗号的索引值'

select LEFT(@str,charindex(',',@str,1)-1) as '第一个值'

select SUBSTRING(@str,charindex(',',@str,1)+1,len(@str)) as '从第一逗号开始截取出后面的字符串'

select LEFT(SUBSTRING(@str,charindex(',',@str,1)+1,len(@str)),CHARINDEX(',',SUBSTRING(@str,charindex(',',@str,1)+1,len(@str)),1)-1) as '中间的值'

select SUBSTRING(SUBSTRING(@str,charindex(',',@str,1)+1,len(@str)),charindex(',',SUBSTRING(@str,charindex(',',@str,1)+1,len(@str)),1)+1,len(@str)) as '最后面的值' --从第二个逗号开始截取出其后的字符串
