sqlserver中遍历字符串的sql语句

复制代码 代码如下:

declare @ddd varchar(50),@split varchar(1)

set @ddd = '12345678,1234567890,1234567890,123456,123456789'

set @split = ','

while(charindex(@split,@ddd)<>0)

begin

select substring(@ddd,1,charindex(@split,@ddd)-1)

set @ddd = stuff(@ddd,1,charindex(@split,@ddd),'')

select @ddd

end
