The above is, plain and simple, wrong. According to the SQL spec,
JOIN binds more tightly than comma in a FROM-list, so what you had was

FROM ..., (enum as p
LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name =
'fachabteilung'))

which of course fails because only p and c are visible in the JOIN's
ON condition. You fixed it by moving "t" to become part of the JOIN
structure.

I was aware that MySQL parses this sort of structure wrongly, but it's
disappointing to hear that sqlite does too :-(
