i have 2 tables same structure but different data.
i have html table generated dynamically using data from the above tables.

the syntax:
<table width="100%" border="1">
        <tr bgcolor="#3399FF">
          <td colspan="5"><div align="center"><font color="#FFFFFF">
<strong>Out</strong></font></div></td>
        </tr>
        <tr>
          <td width="20%"><div align="center">Date</div></td>
          <td width="15%"><div align="center">TT No</div></td>
          <td width="15%"><div align="center">From</div></td>
          <td width="35%"><div align="center">Desc</div></td>
          <td width="15%"><div align="center">Amount</div></td>
        </tr>
<%
      Statement stmt4  = C.createStatement();
      ResultSet RS4    = stmt4.executeQuery("select *,sum(amount) as total from papertrans where type='out' group by type");
      
      while(RS4.next()){
            pdate2 = RS4.getString("date");
            pttno2 = RS4.getString("ttno");
            pfrom2 = RS4.getString("loc");
            pdescription2 = RS4.getString("description");
            pamount2 = RS4.getFloat("amount");
            float ptotal2 = RS4.getFloat("total");
%>
        <tr>
          <td width="20%"><div align="right"><%=pdate2%></div></td>
          <td width="15%"><div align="right"><%=pttno2%></div></td>
          <td width="15%"><div align="right"><%=pfrom2%></div></td>
          <td width="35%"><div align="right"><%=pdescription2%></div></td>
          <td width="15%"><div align="right"><%=sharePrice.format(pamount2)%></div></td>
        </tr>
        <tr>
          <td>&nbsp;</td>
          <td>&nbsp;</td>
          <td>&nbsp;</td>
          <td>Total</td>
          <td><div align="right"><%=sharePrice.format(ptotal2)%></div></td>
        </tr>
     </table>

question:
it only managed to show the 1st info but it showed the amount(ptotal2) correctly.
how am i suppose to display the other info without saperating the query into 2?

Don't calculate the total in your query and don't group by type.  So you get all your records out.  Calculate your total in your JSP.

          float ptotal2 = 0;
     ResultSet RS4    = stmt4.executeQuery("select *,sum(amount) as total from papertrans where type='out'");
   
     while(RS4.next()){
...
         ptotal2 += pamount2;

change is like..
<%
    Statement stmt4  = C.createStatement();
    ResultSet RS4    = stmt4.executeQuery("select * from papertrans where type='out' group by type");
   
     while(RS4.next()){
          pdate2 = RS4.getString("date");
         pttno2 = RS4.getString("ttno");
         pfrom2 = RS4.getString("loc");
         pdescription2 = RS4.getString("description");
         pamount2 = RS4.getFloat("amount");
         float ptotal2 += pamount2;
%>
that should do it

yeah, I'd say it should be
     ResultSet RS4    = stmt4.executeQuery("select * from papertrans where type='out'");
Still no need to group by.

another problem:
i only need to show the total once.

 <td width="15%"><div align="right"><%=sharePrice.format(pamount2)%> </div></td>
   </tr>
<%
   }//i can't put this here
%>
    <tr>
    <td>&nbsp;</td>
...
    <td><%=sharePrice.format(ptotal2)%></td>
