derbytest

=========

derbytest is an embedded derby database that can be hosted on openshift

features include:

- connects in the data directory so that database maintains state across commits

- migration script (using flyway) is raked on every push to openshift

An example is ca.on.conestogac.Lab4.

	package ca.on.conestogac;

	

	import java.sql.*;

	

	public class Lab4 {

		public static void main(String[] args) {

			//set these to be null so that we can finally close them

	        Connection connection = null;

	        Statement oStmt = null;

	        try{

	        	//make a stmt from my SQL

	        	connection = OpenShiftDerbySource.getConnection();

	        	oStmt = connection.createStatement();

	        	String sSQL = "SELECT * FROM PERSON";

	        	ResultSet oRs = oStmt.executeQuery(sSQL);

	        	System.out.println(ResultSetValue.toJsonString(oRs));

	            oRs.close();

	        }catch(Exception e){

	        	e.printStackTrace();

	        }finally{

	        	try{

	        		if(oStmt != null) oStmt.close();

	        		if(connection != null) connection.close();

	        	}catch(Exception e){

	        		e.printStackTrace();

	        	}

	        }

		}

	}

This is a simple select example that also makes use of a helper `ResultSetValue.toJsonString(oRs)`.
