C# asp.net中的OleDbDataReader查询语法错误

我试图执行一个链接不同数据库的查询OleDbDataReader，但查询字符串中出现错误，请注意，此查询是正确的，并且在sql studio manager中成功运行 但是在.Net中，我在

OleDbDataReader reader = myCommand.ExecuteReader();

错误消息：

“PR1”附近的语法不正确

我的代码长查询字符串

protected void Page_Load(object sender, EventArgs e)
{
    string strConString=System.Configuration.ConfigurationManager.ConnectionStrings["WorkflowConnStr"].ConnectionString.ToString();

    string sqlstr = "select coalesce(engdir ,'Total') [engdir]," +
    "SUM(case when a.Status = 'Delivered' then Total else 0 end) as [Delivered],"+
    "SUM(case when a.Status = 'Completed' then Total else 0 end) as [Completed],"+
    "SUM(case when a.Status = 'Pending' then Total else 0 end) as [Pending],"+
    "SUM(case when (a.Status ='Rejected') then Total Else 0 end) as [Rejected],"+
    "COUNT(*) as Total from "+
    "(select count(*) as Total, CurrentActorUID,ReferenceNo, Status,RequestedDate from tbl_ServiceTracking "+
    "where CurrentActorUID is not null and CurrentActorUID <> '' and "+
    "(Status='rejected' or  Status='Completed' or Status='Pending' or Status='Delivered' )and (ServiceNo is not null )"+
    "group by CurrentActorUID,Status,RequestedDate,ReferenceNo) a"+
    "JOIN PR1.dbo.GetUserDetailsE AS b "+
    "ON a.CurrentActorUID = b.PERUserName"+
    "WHERE --b.DirCode=@DirCode "+
     "(CAST(a.RequestedDate AS DATETIME)>='1/1/2014' AND CAST(a.RequestedDate AS DATETIME)<='4/30/2014') "+
    "GROUP BY b.engdir "+
    "WITH ROLLUP HAVING engdir IS NOT NULL OR GROUPING(b.engdir) = 1 ORDER BY "+
    "CASE WHEN b.engdir IS NULL THEN 1 ELSE 0 END ,b.engdir ";

    OleDbConnection myConnection = new OleDbConnection(strConString);
     try {myConnection.Open();}
     catch (Exception err) { System.Diagnostics.Debug.WriteLine(err.Message); }        

    OleDbCommand myCommand = new OleDbCommand(sqlstr, myConnection);        
    OleDbDataReader reader = myCommand.ExecuteReader();
    myCommand.ExecuteReader(CommandBehavior.CloseConnection);

    Chart1.DataBindCrossTable(
        reader,
        "Excellent",
        "Satisfied",
        "Not Satisfied",
        "Total");
}

有什么建议吗？

您错过了一个空白：

"group by CurrentActorUID,Status,RequestedDate,ReferenceNo) a"+

应该是：

"group by CurrentActorUID,Status,RequestedDate,ReferenceNo) a "+

此外，您可以使用文字'@'而不是使用串联，如下所示：

string sqlstr = @"SELECT COALESCE(engdir, 'Total') [engdir], 
                SUM(case when a.Status = 'Delivered' then Total else 0 end) as [Delivered],
                SUM(case when a.Status = 'Completed' then Total else 0 end) as [Completed],
                SUM(case when a.Status = 'Pending' then Total else 0 end) as [Pending],
                SUM(case when (a.Status ='Rejected') then Total Else 0 end) as [Rejected],
                COUNT(*) as Total from 
                (select count(*) as Total, CurrentActorUID,ReferenceNo, Status,RequestedDate from tbl_ServiceTracking
                where CurrentActorUID is not null and CurrentActorUID <> '' and 
                JOIN PR1.dbo.GetUserDetailsE AS b 
                ON a.CurrentActorUID = b.PERUserName
                WHERE --b.DirCode=@DirCode 
                (CAST(a.RequestedDate AS DATETIME)>='1/1/2014' AND CAST(a.RequestedDate AS DATETIME)<='4/30/2014') 
                GROUP BY b.engdir 
                WITH ROLLUP HAVING engdir IS NOT NULL OR GROUPING(b.engdir) = 1 ORDER BY 
                CASE WHEN b.engdir IS NULL THEN 1 ELSE 0 END ,b.engdir";

在您的sql平台中运行查询，从那里您可以轻松地检查错误的来源。只需将查询复制到文本字符串@中

习惯使用换行符等格式设置查询字符串。如果你一眼就能看出你的字符串连接是正确分隔的，空格是完整的，那么这真的有助于发现这样的错误。谢谢你的回答，这真是一个愚蠢的错误：DDon别担心，连Michael Jordan也犯了一个愚蠢的错误D
