Basic use

var nodeQuery = require('ci-node-query');

var connection = ... // Database module connection 

// Three arguments: database type, database connection, database connection library 
var query = nodeQuery.init('mysql', connection, 'mysql2');

// The third argument is optional if the database connection library has the same name as the adapter, eg..
nodeQuery.init('mysql', connection, 'mysql');
// Can be instead
nodeQuery.init('mysql', connection);

// You can also retrieve the instance later
query = nodeQuery.getQuery();

query.select('foo')
	.from('bar')
	.where('x', 3)
	.orWhere({y: 2})
	.join('baz', 'baz.boo = bar.foo', 'left')
	.orderBy('x', 'DESC')
	.limit(2, 3)
	.get(function(/* Adapter dependent arguments */) {
		// Database module result handling
	});
