/**
 * Used to return raw SQL query results.
 * 
 * Refer to {@link SqlQuery} for examples.
 * 
 * 
 * There are convenience methods such as getInteger(), getBigDecimal() etc. The
 * reason for these methods is that the values put into this map often come
 * straight from the JDBC resultSet. Depending on the JDBC driver it may put a
 * different type into a given property. For example an Integer, BigDecimal,
 * Double could all be put into a property depending on the JDBC driver used.
 * These convenience methods automatically convert the value as required
 * returning the type you expect.
