使用特定数字生成主键列

Question

我需要在列＆＃34; NumberList ＆＃34;列中插入位于“开始”和“结束”列之间的数字。 （这应该包括开始和结束数字。）

我用来获得上述结果的查询如下

SELECT DISTINCT Number      
, CONVERT(VARCHAR,Number) + REPLICATE('0',16-LEN(Number)) AS 'Start' 
, CONVERT(VARCHAR,Number) + REPLICATE('9',16-LEN(Number)) AS 'End'
,NULL 'NumberList'      
FROM  Table

请您帮我解决以下问题，因为我希望 NumberList 列也是主键

Create function GetNumbersList (@intStart as bigint, @intEnd as bigint) returns varchar(max) as begin DECLARE @num INT = @intStart DECLARE @numberlist as varchar(max)='' WHILE(@num<=@intEnd) begin set @numberlist=@numberlist + cast(@num as varchar(20)) + N' ' SET @num = @num + 1 end return(rtrim(@numberlist)) End GO select Number , CONVERT(VARCHAR,Number) + REPLICATE('0',16-LEN(Number)) AS 'Start' , CONVERT(VARCHAR,Number) + REPLICATE('9',16-LEN(Number)) AS 'End' , dbo.GetNumbersList (CONVERT(VARCHAR,Number) + REPLICATE('0',16-LEN(Number)), CONVERT(VARCHAR,Number) + REPLICATE('9',16-LEN(Number))) as [NumbersList] from Table
