sqlserver中遍历字符串的sql语句

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
