将数据从临时文件导入永久文件时动态 SQL 出错 table

Question

这是我的查询：

Declare @i int
Declare @Query nvarchar(max)

Set @i = 1

while(@i < 3)
begin
    Select YEAR, MONTH 
    into #temp 
    from Toyota1

    Set @Query = 'Select * into table'+ CASt(@i AS VARCHAR(10)) + 'from #temp'

    Set @i = @i + 1 

    exec (@query)

    Drop Table #temp
end

我收到这些错误：

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '#temp'

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '#temp'.

请帮忙。

也许是这样的：

DECLARE @i     INT = 1
DECLARE @Query NVARCHAR(MAX);

IF OBJECT_ID('tempdb..#temp') IS NOT NULL DROP TABLE #temp;
SELECT TOP (0) [YEAR], [MONTH]
INTO #temp 
FROM Toyota1;


WHILE(@i < 3)
BEGIN
  INSERT #temp ([YEAR], [MONTH])
  SELECT [YEAR], [MONTH]
  FROM Toyota1
  WHERE <some logic here that requires a loop>

  SET @i += 1
END

SELECT * 
INTO <TABLE> 
FROM #temp;

DROP TABLE #temp;
