BigQuery Temp Table Column has no Name-CodePudding

I'm trying to create a temp table in BigQuery, something like:

CREATE TEMP TABLE myTmpTable AS
  SELECT t.event_id, MAX(t.event_date)
  FROM eventsTable t
  WHERE t.field_name = "foo"
  AND t.new_string = "bar"
  GROUP BY t.event_id;

This results in error "CREATE TABLE columns must be named, but column 2 has no name". I understand that it can't extract a column name from MAX(t.event_date). Is there a way I can specify a column name?

Is there a way I can specify a column name?

Use below

SELECT t.event_id, MAX(t.event_date) AS max_event_date

Meantime the whole SELECT looks wrong to me - if you group by issue_id then event_id should be somehow aggregated. Or you might want to group by event_id instead!
