# DO SOMETHING USING lasID

def handle_error(self, e):
log.err(e)
我们下面第二行的lastID对应于插入第一行吗?或者它可能来自任何runInteraction线程?扭曲的adbapi:runInteraction last_insert_id()
tx.execute("INSERT INTO User (user_name) VALUES (%s)",(name))
tx.execute("SELECT LAST_INSERT_ID()")
非常感谢你的反应。 已经3年多了,我发布了这个,并已经想出了你说的话。我非常感谢你为此提供答案。 :) –
