Subject Re: Tree view in Derby Stored Procedure
Date Sat, 18 Apr 2015 10:41:37 GMT
Hi Rick,I am pasting code from program which did not work for recursion very
well. At line 13 executeQuery is returning a resultset. This is where I am
running into problem. ResultSet being a cursor I am not able to use
recursion. It would be better if I can return from executeQuery a JSON or
XML. JSON is scalar and can be manipulated freely. Is there any such way to
query the database.1 package recursion;2 import java.sql.*;3 public class
RecursiveSQL {4	public static EmpRecord databaseConnection () throws
SQLException {5      Connection c = null;6		Statement s = null;7		ResultSet
rs = null;8		String ename = null;9		EmpRecord emp = new EmpRecord();10		try
{11			c = DriverManager.getConnection("jdbc:derby:scott");12			s =
c.createStatement();13			rs = s.executeQuery("SELECT empno, ename FROM
EMP");14			rs.next();15			System.out.println("rs="+rs.getString("ename"));16		
emp.empno = rs.getInt("empno");17			emp.ename = rs.getString("ename");18		
c.close();19		} 20		catch (SQLException sx) {21			System.out.println ("
Database Connect SQL Exception.
");22			sx.printStackTrace();23		}24		return (emp);25	}         26}thanks
for the help,BalNagendra
