from子句语法错误
在此sql查询中，尝试读取excel文件。
在sql server中运行此查询时，它工作正常：

OleDbCommand objCmd = new OleDbCommand(
    "select policyNo ,[0] as 'Count of Deleted',[1],[3],[0]+[3] as 'Count of Transaction'
       from (select policyNo,isnull(Deleted,3) as deleted
       from [Sheet1$])t1 pivot (count(deleted) for deleted in ([0],[1],[3]))t2", objConn);
