sql-server - 使用 Select Into 时出现错误消息

Question

我用下面的代码，

SELECT RowsCount = ROW_NUMBER() OVER(ORDER BY PrijsBoek.[Item Code] DESC, PrijsBoek.[Buy-From BP Code] DESC),
*
INTO #Student
FROM [iqbs DataWarehouse].[Purchase].[factPurchasePriceBooks] as PrijsBoek

DECLARE @MaxRowsCount INT
SET @MaxRowsCount = (SELECT MAX(RowsCount) FROM #Student)
DECLARE @Iter INT
SET @Iter = (SELECT MIN(RowsCount) FROM #Student)
WHILE @Iter <= @MaxRowsCount
BEGIN
    SELECT *
    FROM #Student
    WHERE RowsCount = @Iter
    SET @Iter = @Iter + 1
END
DROP TABLE #Student

但我收到以下错误消息：

Msg 207, Level 16, State 1, Line 7
Invalid column name 'RowsCount'.
Msg 207, Level 16, State 1, Line 9
Invalid column name 'RowsCount'.
Msg 207, Level 16, State 1, Line 14
Invalid column name 'RowsCount'.

有人有什么线索吗？

尝试以下代码并将其应用于您的情况：

SELECT RowsCount = ROW_NUMBER() OVER(ORDER BY Message_Id DESC), * 
INTO #Student
FROM sys.Messages

DECLARE @MaxRowsCount INT = @@ROWCOUNT, @Iter INT = 1, @Text AS VARCHAR(MAX);
SELECT @Iter , @MaxRowsCount

WHILE @Iter <= @MaxRowsCount
BEGIN
    SELECT @Text = Text FROM #Student WHERE RowsCount = @Iter
    PRINT @Text
    SET @Iter += 1;
END
DROP TABLE #Student
