> the following query:
> {code:sql}
> SELECT a.email, b.email, lower(a.email), lower(b.email) FROM test_tables.test_emails as a left join views.test_view_emails as b on lower(a.email)=lower(b.email)
> {code}
> leads to the following results:
>  !test_emails_bug1.jpg|thumbnail! 
> though running the same query on PostgreSQL leads to the following results:
>  !test_emails_pg.jpg|thumbnail! 
> so this query mentioned above must work as on PostgreSQL putting null values for the b field table where conditions can't be performed.
