Case insensitive searches
From ClassDBI
Class::DBI provides two simple search() methods for you: the normal search() and search_like().
Internally each of these is a single line method:
sub search { shift->_do_search("=" => @_) }
sub search_like { shift->_do_search(LIKE => @_) }
This simply passes on your search criteria and prepends a token that will become the search term in the SQL ("column = ?" or "column LIKE ?").
This means that if your database supports further types of search terms you can add trivial methods to work with them:
sub search_ilike { shift->_do_search(ILIKE => @_) }
sub search_regex { shift->_do_search(RLIKE => @_) }
This involves calling an undocumented private method, which is a little naughty. Future versions of Class::DBI may have a nicer interface to this.
