    ,      true
    ,      'act'
    ,      'act-' || to_char(act.id)
    from   exactonlinerest..accounts@eol act
    --
    -- Skip default and missing icons.
    --
    where  logothumbnailurl not like '%placeholder%'
    and    coalesce(length(logothumbnailurl), 0) > 0

    --
    -- Get the logos.
