HORRIBLE SOLUTIONS everywhere on internet. This is probably the simplest in the world. <pre><code>PrintWriter out=response.getWriter(); out.print("&lt;html>"); out.print("&lt;body>"); out.print("&lt;form>"); out.print("&lt;textarea rows='5' columns='500' name='t1'>&lt;/textarea>"); //out.print("&lt;input type='text' name='t2'>"); //out.print("c&lt;input type='checkbox' value='c' name='t1'>"); //out.print("d&lt;input type='checkbox' value='d' name='t1'>"); out.print("&lt;input type='submit' value='execute' name='b1'>"); // out.print("&lt;input type='submit' value='show' name='b1'>"); //out.print("&lt;input type='submit' value='query' name='b1'>"); String a,c; a=request.getParameter("t1"); //b=request.getParameter("t2"); c=request.getParameter("b1"); if(c!=null) { try { Class.forName("com.mysql.jdbc.Driver"); Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/saransh","root",""); Statement st=con.createStatement(); if(a.startsWith("delete")) { out.print(" "); out.print("delete query execution..."); //st.executeUpdate("insert into student2(name,address) values('"+a+"',"+b+"')") ; st.executeUpdate(a); } else if(a.startsWith("select")) { out.print(" "); out.print("select query execution..."); ResultSet rs=st.executeQuery(a); ResultSetMetaData m1=rs.getMetaData(); out.print(" "); for(int i=1;i<=m1.getColumnCount();i++) {String x1=m1.getColumnLabel(i); out.print(" "+x1);} out.print(" ");//name of label while(rs.next()) { String s0=rs.getString("Stu_roll"); String s1=rs.getString("name"); String s2=rs.getString("address"); out.print(s0+" "+s1+" "+s2); out.print(" "); }} else if(a.startsWith("insert")) { out.print(" "); out.print("insert query execution..."); st.executeUpdate(a); } else if(a.startsWith("drop")) { out.print(" "); out.print("drop query execution..."); st.executeUpdate(a); } } catch (Exception e) { out.print(e); // TODO: handle exception } } out.print("&lt;/form>"); out.print("&lt;/body>"); out.print("&lt;/html>"); </code></pre> remove commented lines. only problem is that queries are case sensitive. You can figure out what string operation to use to make it 'ignore case'.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
