與參數和OleDbCommand的工作。在分組時，Crystal Reports

Question

我有組SQL語句通過和參數：

string comstring = 
    "SELECT NOVI.GBR as gbrnov, 
      NOVI.AB as abnov, 
      NALOG1.DATA as datanov, 
      Min(NALOG1.POCKM) AS MinOfPOCKM, 
      Max(NALOG1.KRAJKM) AS MaxOfKRAJKM, 
      (Max(NALOG1.KRAJKM)-Min(NALOG1.POCKM)) AS RAZLIKA, 
      Count(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)) AS Gorivo, 
      Avg(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)/100) AS potrosgor100km, 
      Sum(IIf(([MAGACIN.SIFRA]='0993050' Or [MAGACIN.SIFRA]='0993051'),[MAGACIN.KOL],Null)) AS Motmaslo, 
      Sum(IIf(([MAGACIN.SIFRA]='0992201'),[MAGACIN.KOL],Null)) AS Addblue, 
      ([Addblue]/[Gorivo])*100 AS Addbluegor, 
      Sum(IIf(([MAGACIN.SIFRA]='0999001'),[MAGACIN.KOL],Null)) AS Antifriz, 
      NOVI.DATAP, 
      NOVI.DATAS, 
      IIf(([NOVI].[KM]<=([NOVI].[KMS1]+[NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1]+[NOVI].[KMP2])),'PROVERKA',''))) AS Zabeleska 
    FROM (NALOG1 INNER JOIN NOVI ON NALOG1.GBRV = NOVI.GBR) 
    INNER JOIN MAGACIN ON NOVI.GBR = MAGACIN.GBR 
     where (((NOVI.GBR)>=? And (NOVI.GBR)<=?) 
      AND (((NOVI.AB)=?) 
      OR ((NOVI.AB)=?)) 
      AND ((NALOG1.DATA)<=? and (NALOG1.DATA)>=?)) 
    GROUP BY NOVI.GBR, 
       NOVI.AB, 
       NALOG1.DATA, 
       ([Addblue]/[Gorivo])*100, 
       NOVI.DATAP, 
       NOVI.DATAS, 
       IIf(([NOVI].[KM]<=([NOVI].[KMS1]+[NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1]+[NOVI].[KMP2])),'PROVERKA','')))"; 

我得到一個錯誤No value given for one or more required parameters在

oleDBDataAdapter1.Fill(dataSet2,"Tabela"); 

當某些值使用它如：

string comstring = 
    "SELECT NOVI.GBR as gbrnov, 
      NOVI.AB as abnov, 
      NALOG1.DATA as datanov, 
      Min(NALOG1.POCKM) AS MinOfPOCKM, 
      Max(NALOG1.KRAJKM) AS MaxOfKRAJKM, 
      (Max(NALOG1.KRAJKM)-Min(NALOG1.POCKM)) AS RAZLIKA, 
      Count(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)) AS Gorivo, 
      Avg(IIf(([MAGACIN.SIFRA]='0991000'),[MAGACIN.KOL],Null)/100) AS potrosgor100km, 
      Sum(IIf(([MAGACIN.SIFRA]='0993050' Or [MAGACIN.SIFRA]='0993051'),[MAGACIN.KOL],Null)) AS Motmaslo, 
      Sum(IIf(([MAGACIN.SIFRA]='0992201'),[MAGACIN.KOL],Null)) AS Addblue, 
      ([Addblue]/[Gorivo])*100 AS Addbluegor, 
      Sum(IIf(([MAGACIN.SIFRA]='0999001'),[MAGACIN.KOL],Null)) AS Antifriz, 
      NOVI.DATAP, 
      NOVI.DATAS, 
      IIf(([NOVI].[KM]<=([NOVI].[KMS1]+[NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1]+[NOVI].[KMP2])),'PROVERKA',''))) AS Zabeleska 
    FROM (NALOG1 INNER JOIN NOVI ON NALOG1.GBRV = NOVI.GBR) 
    INNER JOIN MAGACIN ON NOVI.GBR = MAGACIN.GBR 
     where (((NOVI.GBR)>='1001' And (NOVI.GBR)<='1080') 
     AND (((NOVI.AB)='AK') 
     OR ((NOVI.AB)='AK')) 
     AND ((NALOG1.DATA)<=#10/31/2011# 
     and (NALOG1.DATA)>=#10/31/2011#)) 
    GROUP BY NOVI.GBR, 
       NOVI.AB, 
       NALOG1.DATA, 
       ([Addblue]/[Gorivo])*100, 
       NOVI.DATAP, 
       NOVI.DATAS, 
       IIf(([NOVI].[KM]<=([NOVI].[KMS1]+[NOVI].[KMS2])),'ZA SERVIS',(IIf(([NOVI].[KM]<=([NOVI].[KMP1]+[NOVI].[KMP2])),'PROVERKA','')))"; 

沒有任何問題。

有人可以幫我嗎？

Answer 1

它的問題與您的查詢：

where (((NOVI.GBR)>=? And (NOVI.GBR)<=?) 
      AND (((NOVI.AB)=?) 
      OR ((NOVI.AB)=?)) 
      AND ((NALOG1.DATA)<=? and (NALOG1.DATA)>=?)) 

您需要提供的，而不是?應有的價值，也許你可能會做'?'，但我認爲它不會(NALOG1.DATA)工作（通過觀察你的其他查詢我猜，它的數據類型是註釋Date）

編輯：

如果您正在使用參數，那麼您需要按照使用?的順序傳遞它們。如果您在查詢中使用6 ?不能使用命名參數，如以下，在oledbcommand

command.Parameters.AddWithValue("@param1", "1001"); 

然後，你需要按順序通過6個參數。

 OleDbParameter[] oledbParams = new OleDbParameter[6]; 

     //To be added in proper order. 
     oledbParams[0] = new OleDbParameter("PN1", "1001"); 
     oledbParams[1] = new OleDbParameter("PN2", "1002"); 
     . 
     . 
     oledbParams[6] = new OleDbParameter("DateValue", DateTime.Now.Date); 

     foreach (var p in oledbParams) 
     { 
      command.Parameters.Add(p); 
     }
