DATAJDBC-309 - Add infrastructure for semantic SQL generation

[mp911de]

We now provide a Statement Builder API to fluently build SQL statements and render these to a SQL string.

This change introduces support for SELECT.

SelectBuilder builder = StatementBuilder.select();

Table employee = SQL.table("employee");
Table department = SQL.table("department");

Column name = employee.column("name").as("emp_name");
Column department_name = employee.column("name").as("department_name");

Select select = builder.select(name, department_name).from(employee).join(department)
		.on(SQL.column("department_id", employee)).equals(SQL.column("id", department))
		.and(SQL.column("tenant", employee)).equals(SQL.column("tenant", department))
		.orderBy(OrderByField.from(name).asc()).build();

String sql = SqlRenderer.render(select);

SELECT employee.name AS emp_name, employee.name AS department_name FROM employee JOIN department ON employee.department_id = department.id AND employee.tenant = department.tenant ORDER BY emp_name ASC
