In its current incarnation, this class's functionality is limited, regardless of its decent level of SQL abstraction. Therefore, in this fourth part of the series I'm going to enhance it by making it capable of working with LIKE clauses in a straightforward way.

They look at using LIKE to match values in various columns of the tables and add in a fetchLike method that lets you specify the column to search, the pattern to match on and the table to search in.
