我正在从Web应用程序执行以下查询，并访问2007查询向导。我得到两个不同的结果。

SELECT R.Rept_Name, D.Dist_Name,S.State_Name FROM (tblReporter AS R LEFT JOIN tblDist AS D ON R.Dist_Id=D.Dist_Id) LEFT JOIN  tblState AS S ON S.State_Id=R.State_Id WHERE R.Rept_Name LIKE '*Ra*' ORDER BY R.Rept_Name;

Web应用程序的结果为0行，查询向导的结果为2行。如果删除条件，则两个结果均相同。请帮助我查询有什么问题。如果有其他信息需要，请告诉我。

Web应用程序代码…

public DataTable getRept(string rept, string mobno)
{
    DataTable dt = new DataTable();
    using (OleDbConnection conn = new OleDbConnection(getConnection()))
    {
        using (OleDbCommand cmd = conn.CreateCommand())
        {
            cmd.CommandType = CommandType.Text;
            cmd.CommandText = "SELECT R.Rept_Name, D.Dist_Name,S.State_Name FROM (tblReporter AS R LEFT JOIN tblDist AS D ON R.Dist_Id=D.Dist_Id) LEFT JOIN  tblState AS S ON S.State_Id=R.State_Id WHERE R.Rept_Name LIKE '*" + rept + "*'  ORDER BY R.Rept_Name;";
            conn.Open();
            using (OleDbDataReader sdr = cmd.ExecuteReader())
            {
                if (sdr.HasRows)
                    dt.Load(sdr);
            }

        }
    }
    return dt;
}
