展开Recordset并添加DATEADD

Question

我试图从名为＆＃39; TBL_FBNK_LIMIT_HIST_TRANS_SPLIT＆＃39;并根据频率＆＃39;扩展号码。字段，更新DateIncrement，并将所有内容加载到名为＆＃39; TBL_FBNK_LIMIT_HIST_TRANS_SPLIT_FINAL＆＃39;

的最终表中

这是我的DLL

关键在于我知道在12/31/2017和9/30/2019之间有7个季度，我想在每个季度结束日期之前将DateIncrement递增，从2017年12月31日到9月二千零一十九分之三十〇。我怎样才能做到这一点？我想出了下面的脚本，它应该非常接近，但它一直告诉我我的语法不正确（＆＃39; UGH !!!

我希望最终的DateIncrement看起来像这样。

它将为每个Credit_Line_No和AsOfDate重置，所以我认为我需要按这两个字段分组......我想...我正在使用SQL Server 2008。

  select CREDIT_LINE_NO,LIMIT_CURRENCY,AMOUNT,REVIEW_FREQUENCY,STARTDATE,EXPIRYDATE,FREQUENCY,AsOfDate,EFFECTIVESTARTDATE, DateIncrement,
         1 as Rec_Iteration
  from TBL_FBNK_LIMIT_HIST_TRANS_SPLIT
  where FREQUENCY > 1
  union all  
  select CREDIT_LINE_NO,LIMIT_CURRENCY,AMOUNT,REVIEW_FREQUENCY,STARTDATE,EXPIRYDATE,FREQUENCY,AsOfDate,EFFECTIVESTARTDATE, DateIncrement,
        Rec_Iteration + 1
  from cte
  where Rec_Iteration < FREQUENCY
)
INSERT TBL_FBNK_LIMIT_HIST_TRANS_SPLIT_FINAL (CREDIT_LINE_NO,LIMIT_CURRENCY,AMOUNT,REVIEW_FREQUENCY,STARTDATE,EXPIRYDATE,FREQUENCY,AsOfDate,EFFECTIVESTARTDATE, DATEADD(qq,1,STARTDATE) as DateIncrement)
