executemany statement with a subquery (no replies)

Hi all,

I have to insert many rows into DB with some nested select subquery.

I tried something like that:

eventsFlat = []
eventsFlat.append((event.id1, event.id2, event.league, event.date, event.type, event.subtype, event.period))
...
self.__cursor.executemany(
"""INSERT INTO events (mainevent_id, eventtype_id, eventsubtype_id, period_id) VALUES
((select id from mainevents where first_competitor_id=%s and second_competitor_id=%s and league_id=%s and event_date=%s), %s, %s, %s)""",
eventsFlat)

All I got is the error:

TypeError('not all arguments converted during string formatting',)

Is this possible to use executemany to insert rows but with some select subquery included in?

Kind regards,
Rob
