）使用C＃执行SQLCommand时出错（

Question

）

我对使用C＃（Visual Studio 2010）的ADO.NET很陌生。使用LinqToSql不是一种选择，因为底层数据库是Compact Edition 3.5（不幸）。

与我下面所显示的代码得到一个错误：“有一个错误解析查询[令牌行号= 2，令牌行偏移= 38，令牌错误= AGENTNAME。”

谁能告诉我，我在做什么错了？

using (SqlCeConnection oConn = new SqlCeConnection(connectionstring)) 
     { 
      string strSql = @"select 
         a.name as 'AgentName', 
         t.description as 'JobType', 
         s.description as 'Status', 
         count(j.statusid) as 'Count' 
        from 
         jobs as j 
          inner join agents as a on j.agentid = a.id 
          inner join statusdictionary as s on j.statusid = s.id 
          inner join jobtypedictionary as t on j.jobtypeid = t.id 
        where 
         convert(datetime,starttime,0) between @FirstDate and @LastDate 
         AND j.JobTypeID = @JobTypeID AND j.AgentID = @AgentID 
        group by 
         s.description, 
         t.description, 
         a.name order by a.name,  
         t.description"; 
      SqlCeCommand oCmd = new SqlCeCommand(strSql, oConn); 

      SqlCeParameter fdparam = new SqlCeParameter(); 
      fdparam.ParameterName = "@FirstDate"; 
      fdparam.Value = firstdate; 
      oCmd.Parameters.Add(fdparam); 

      SqlCeParameter ldparam = new SqlCeParameter(); 
      ldparam.ParameterName = "@LastDate"; 
      ldparam.Value = lastdate ; 
      oCmd.Parameters.Add(ldparam); 

      SqlCeParameter JIDparam = new SqlCeParameter(); 
      JIDparam.ParameterName = "@JobTypeID"; 
      JIDparam.Value = jobtypeid; 
      oCmd.Parameters.Add(JIDparam); 

      SqlCeParameter AIDparam = new SqlCeParameter(); 
      AIDparam.ParameterName = "@AgentID"; 
      AIDparam.Value = jobtypeid; 
      oCmd.Parameters.Add(AIDparam); 

      oConn.Open(); 
      SqlCeDataReader oReader = oCmd.ExecuteReader(); 

Answer 1

我认为你需要丢掉'AgentName'周围的引号。

Answer 2

更改单引号“”以括号[]

a.name as [AgentName],
