Example 1

		final int[] tableNumbers,
		final int[] columnNumbers,
		final int[] formulaNumbers) {

	Arrays.sort( tableNumbers ); //get 'em in the right order (not that it really matters)

	//render the where and from parts
	int drivingTable = tableNumbers[0];
	final String drivingAlias = generateTableAlias(
			getRootAlias(),
			drivingTable
	); //we *could* regerate this inside each called method!
	final String where = createWhereByKey( drivingTable, drivingAlias );
	final String from = createFrom( drivingTable, drivingAlias );

	//now render the joins
	JoinFragment jf = createJoin( tableNumbers, drivingAlias );

	//now render the select clause
	SelectFragment selectFragment = createSelect( columnNumbers, formulaNumbers );

	//now tie it all together
	Select select = new Select( getFactory().getDialect() );
	select.setSelectClause( selectFragment.toFragmentString().substring( 2 ) );
	select.setFromClause( from );
