Question

我有以下代码来获取今天的日期：

today = str(date.today()) //2019-01-07

我想从timestamp列不像今天那样的数据库中获取所有记录。功能如下：

def get_vehicle_references():
  conn = db_connection()
  cur = conn.cursor()
  s = "SELECT reference, reference_url FROM vehicles v WHERE (NOT EXISTS (select reference from daily_run_vehicle rv WHERE (handled = %s or (handled = %s and retries >= %s)) and DATE(rv.timestamp) <> %s AND reference = v.reference))"
  cur.execute(s, (True, False, 5, today))
  return cur.fetchall()

时间戳列采用以下格式：2019-01-07 11:10:18.491368

我想从vehicles表中获取所有记录，而timestamp表中的daily_run_vehicle列不是今天。

但是此查询还为我提供了今天的记录。

有什么主意吗？

更新：

因此，我尝试投射它，查询如下：

s = "SELECT reference, reference_url, timestamp FROM vehicles v WHERE (NOT EXISTS (select reference from daily_run_vehicle rv WHERE (handled = %s or (handled = %s and retries >= %s)) AND rv.timestamp::date = %s AND reference = v.reference))"
cur.execute(s, (True, False, 5, today))

但是我仍然有同样的问题。

获取时间戳不是当前日期的记录
