为什么这个错误？

SELECT (CASE 
      WHEN BalanceTransfer.mobile_operator_desc = 'Paypoint' 
       AND money_transfer.MoneyTransfer = 'NCELL' THEN 'Paypoint' 
      WHEN BalanceTransfer.mobile_operator_desc = 'Paypoint' 
       AND money_transfer.MoneyTransfer = 'UTLP' THEN 'Paypointutl' 
      WHEN BalanceTransfer.mobile_operator_desc = 'Paypoint' 
       AND money_transfer.MoneyTransfer = 'SIMTV' THEN 'Paypointsimtv' 
      ELSE BalanceTransfer.mobile_operator_desc 
     END), 
     ISNULL(CONVERT(VARCHAR, DT_date, 101), '''') Txndate, 
     COUNT(*)          txn, 
     reseller_agent.reseller_id, 
     reseller_agent.userName,

     AND Status <> 'confirming' 
     AND BalanceTransfer.mobile_operator IN(1, 2, 6, 14, 15) 
     AND ISNULL(money_transfer.IsUtility, 'n') = 'y' 
     AND money_transfer.Mobile_Operator IS NOT NULL 
GROUP BY BalanceTransfer.mobile_operator_desc, 
      money_transfer.MoneyTransfer, 
      reseller_agent.reseller_id, 
      reseller_agent.userName, 
      ISNULL(CONVERT(VARCHAR, DT_date, 101), '''') 

SELECT * 
FROM #tempRoutewise 

Answer 1

正如马丁在他的评论中指出的那样，您的第一列没有名称。您正在尝试创建一个表格。很显然，该表中的所有列都必须有一个名称，名称是您选择的列的名称。如果你尝试：

SELECT CASE 
      WHEN BalanceTransfer.mobile_operator_desc = 'Paypoint' 
       AND money_transfer.MoneyTransfer = 'NCELL' THEN 'Paypoint' 
      WHEN BalanceTransfer.mobile_operator_desc = 'Paypoint' 
       AND money_transfer.MoneyTransfer = 'UTLP' THEN 'Paypointutl' 
      WHEN BalanceTransfer.mobile_operator_desc = 'Paypoint' 
       AND money_transfer.MoneyTransfer = 'SIMTV' THEN 'Paypointsimtv' 
      ELSE BalanceTransfer.mobile_operator_desc 
     END AS mobile_operator_desc , 
     ISNULL(CONVERT(VARCHAR, DT_date, 101), '''') Txndate, 
     COUNT(*)          txn, 
     reseller_agent.reseller_id, 
     reseller_agent.userName, 
     SUM(ISNULL(selling_price, 0.00))    amount, 
     SUM(ISNULL(amount, 0.00))     facevalue 

它应该工作。
