SQL 递归使用

直接贴代码吧= =

WITH CTE AS
  (
  -->Begin 一个定位点成员
   SELECT COUNTRYORDERID,HSNAME, COUNTRYNAME,PARENTORDERID,
   IMPORTCURRENTSUMAMOUNT,
   IMPORTCONTRASTSUMAMOUNTPERCENTAGE,
   IMPORTCURRENTSUMAMOUNTPERCENTAGE,
   CAST(COUNTRYNAME AS NVARCHAR(max)) AS TE,0 AS Levle FROM #TempTableDetail
    WHERE PARENTORDERID IS NULL AND HSNAME IN (SELECT HSNAME FROM #TempTableData)
  -->End
  UNION ALL
  -->Begin一个递归成员
   SELECT #TempTableDetail.COUNTRYORDERID, #TempTableDetail.HSNAME, #TempTableDetail.COUNTRYNAME,#TempTableDetail.PARENTORDERID,
   #TempTableDetail.IMPORTCURRENTSUMAMOUNT,
   #TempTableDetail.IMPORTCONTRASTSUMAMOUNTPERCENTAGE,
   #TempTableDetail.IMPORTCURRENTSUMAMOUNTPERCENTAGE,
   CAST(REPLICATE(‘  ‘,LEN(CTE.TE))+#TempTableDetail.COUNTRYNAME AS NVARCHAR(MAX)) AS TE,Levle+1 AS Levle
    FROM #TempTableDetail INNER JOIN CTE
    ON #TempTableDetail.PARENTORDERID=CTE.COUNTRYORDERID
    --group by #TempTableDetail.HSNAME
    WHERE #TempTableDetail.HSNAME IN (SELECT HSNAME FROM #TempTableData)
  -->End
  )

  INSERT INTO #TempResult(COUNTRYORDERID,HSNAME,COUNTRYNAME,IMPORTCONTRASTSUMAMOUNTPERCENTAGE,IMPORTCURRENTSUMAMOUNTPERCENTAGE,IMPORTCURRENTSUMAMOUNT)
  SELECT DISTINCT COUNTRYORDERID, HSNAME,TE,IMPORTCONTRASTSUMAMOUNTPERCENTAGE,
   IMPORTCURRENTSUMAMOUNTPERCENTAGE,IMPORTCURRENTSUMAMOUNT FROM CTE ORDER BY HSNAME,COUNTRYORDERID;

效果：
