没有从数据库中获取总记录

我的数据库表中有4条记录,但我只从该函数中获取一条记录。请检查我的代码一次。当我在这个函数中调用getMaterialTransferRecords()函数时,我有另一个函数getMaterialUnit()。我无法找到解决方案。请任何人帮助我。

这是我在sqlyog中执行的查询。请检查一次

以上是我的查询,下面是结果。

这就是我调用函数的方式。

// Fetch Data from User Table
        int startPageIndex = Integer.parseInt(request.getParameter("jtStartIndex"));
        int recordsPerPage = Integer.parseInt(request.getParameter("jtPageSize"));

        String jtSorting = request.getParameter("jtSorting");
        MaterialTransferUtils utils = new MaterialTransferUtils();
        //System.out.println("Cash Purchases Start Page Index:"+startPageIndex+" recordsPerPage:"+recordsPerPage);

        if(jtSorting != null)
        {
            jtSorting = jtSorting.replaceAll("material_destn_code", "material_destn_code");
            jtSorting = jtSorting.replaceAll("date", "transferred_on");
        }
        // Fetch Data from Cash Memo Table
        mtList = utils.getMaterialTransferRecords(startPageIndex, recordsPerPage,jtSorting);

请检查一次代码。

public List<MaterialTransferBean> getMaterialTransferRecords(int startPageIndex, int recordsPerPage,String jtSorting)
{
    List<MaterialTransferBean> list = new ArrayList<MaterialTransferBean>();
    con=com.s2s.bssb.database.ConnectionFactory.getConnection();
    MaterialTransferBean mtbean = null;

    String sortStr = "material_destn_code DESC";
    if(null != jtSorting)
        sortStr = jtSorting;

    String query = "SELECT sno,material_loc_code,transferred_on,mr_no,do_no,material_destn_code,material_id,quantity,unit_price, "
            + "gst,remarks FROM material_transfer ORDER BY "+sortStr+" LIMIT "+recordsPerPage+" offset "+startPageIndex+"";

    System.out.println(query);

    if(con!=null){
        try{
            ps=con.prepareStatement(query);
            rs=ps.executeQuery();
            while(rs.next()){
                MaterialTransferBean bean = new MaterialTransferBean();
                bean.setSno(rs.getInt("sno"));
                bean.setMaterial_loc_code(rs.getString("material_loc_code"));
                bean.setDate(rs.getDate("transferred_on"));
                bean.setMr_no(rs.getString("mr_no"));
                bean.setDo_no(rs.getString("do_no"));
                bean.setMaterial_destn_code(rs.getString("material_destn_code"));
                bean.setQuantity(rs.getDouble("quantity"));
                bean.setUnit_price(rs.getDouble("unit_price"));
                bean.setAmount(rs.getDouble("quantity")*rs.getDouble("unit_price"));
                bean.setGst(((rs.getDouble("quantity")*rs.getDouble("unit_price"))*(rs.getDouble("gst")))/100);
                bean.setTtl_amount((rs.getDouble("quantity")*rs.getDouble("unit_price"))+(((rs.getDouble("quantity")*rs.getDouble("unit_price"))*(rs.getDouble("gst")))/100));
                bean.setRemarks(rs.getString("remarks"));

                mtbean = new MaterialTransferBean();

                mtbean = getMaterialUnit(rs.getInt("material_id"));

                bean.setMaterial(mtbean.getMaterial());
                bean.setUnit(mtbean.getUnit());

                list.add(bean);
            }
            rs.close();
            com.s2s.bssb.database.ConnectionDB.close(con);
            com.s2s.bssb.database.ConnectionDB.close(ps, con);
        }catch(SQLException sql_ex){
            sql_ex.printStackTrace();
        }
    }else{
        System.out.println("Connection Not Created");
    }

    return list;
}

public MaterialTransferBean getMaterialUnit(int material_id){
    MaterialTransferBean bean = null;
     con=com.s2s.bssb.database.ConnectionFactory.getConnection();
        String query = "select material,unit from materials where id=?";

        if(con!=null){
            try{
                ps=con.prepareStatement(query);
                ps.setInt(1, material_id);
                rs=ps.executeQuery();
                while(rs.next()){
                    bean = new MaterialTransferBean();
                    bean.setMaterial(rs.getString("material"));
                    bean.setUnit(rs.getString("unit"));
                }

                sql_ex.printStackTrace();
