我想在alerts_data中只插入3个第一列。我知道值必须与列的数量相同，但如果我删除future_conditions_views，则查询将无效。
我怎样才能插入前3个？
INSERT INTO alerts_data (alerts_data_hash, alerts_data_id, alerts_data_hash_id)
SELECT behaviour.hash, future_conditions_alert, , CONCAT(behaviour.hash, future_conditions_alert) AS alerts_data_hash_id, future_conditions_views
FROM behaviour, active, future_conditions
WHERE behaviour.hash = active.hash
AND behaviour.url = future_conditions_url
AND active.last_active >= NOW( ) - INTERVAL 1 MINUTE
AND behaviour.timestamp >= NOW( ) - INTERVAL future_conditions.future_conditions_day DAY
GROUP BY behaviour.hash, behaviour.url
HAVING COUNT( * ) >= future_conditions.future_conditions_views
ON DUPLICATE KEY UPDATE alerts_data.alerts_data_hash_id = alerts_data.alerts_data_hash_id
