Out of curiosity, what would be the results of:
Code:
SELECT DISTINCT(city) FROM places WHERE name <> "bob"

Does "perth" show up?

Class::DBI::Test::SQLite(3pm)				User Contributed Perl Documentation			     Class::DBI::Test::SQLite(3pm)

NAME
Class::DBI::Test::SQLite - Base class for Class::DBI tests SYNOPSIS
use base 'Class::DBI::Test::SQLite'; __PACKAGE__->set_table('test'); __PACKAGE__->columns(All => qw/id name film salary/); sub create_sql { return q{ id INTEGER PRIMARY KEY, name CHAR(40), film VARCHAR(255), salary INT } } DESCRIPTION
This provides a simple base class for Class::DBI tests using SQLite. Each class for the test should inherit from this, provide a create_sql() method which returns a string representing the SQL used to create the table for the class, and then call set_table() to create the table, and tie it to the class. METHODS
set_table __PACKAGE__->set_table('test'); This combines creating the table with the normal Class::DBI table() call. create_sql (abstract) sub create_sql { return q{ id INTEGER PRIMARY KEY, name CHAR(40), film VARCHAR(255), salary INT } } This should return, as a text string, the schema for the table represented by this class. perl v5.12.4 2005-05-24 Class::DBI::Test::SQLite(3pm)
