如何从while循环创建sql server cte
我这样的循环
我这样的循环
declare @ind as int declare @code as nvarchar set @ind = 0 while @ind < 884 begin select @ind = @ind + 1 --here execute Procedure --and set return value to variable set @code = cast (@ind as nvarchar) end
解决方法
如果你需要表:
;WITH Sec(Number) AS ( SELECT 0 AS Number UNION ALL SELECT Number + 1 FROM Sec WHERE Number < 884 ) SELECT * FROM Sec OPTION(MAXRECURSION 0)
如果你需要一个字符串:
;WITH Sec(Number) AS ( SELECT 0 AS Number UNION ALL SELECT Number + 1 FROM Sec WHERE Number < 884 ) SELECT STUFF(a.[Str],1,'') FROM ( SELECT (SELECT ',' + CAST(Number AS NVARCHAR(3)) FROM Sec FOR XML PATH(''),TYPE ).value('.','varchar(max)') AS [Str] ) AS a OPTION(MAXRECURSION 0)
