python – 扭曲的adbapi：runInteraction last_insert_id()

class MySQL(object):

    def __init__(self):
        self.dbpool = adbapi.ConnectionPool(
            'MySQLdb',db='dummy',user='root',passwd='',host = 'localhost',cp_reconnect = True,cursorclass=MySQLdb.cursors.DictCursor,charset='utf8',use_unicode=True
        )

    def process(self,item):
        query = self.dbpool.runInteraction(self.conditionalInsert,item).addErrback(self.handle_error)        
        return item


    def conditionalInsert(self,tx,item):
        tx.execute("INSERT INTO User (user_name) VALUES (%s)",(name))
        tx.execute("SELECT LAST_INSERT_ID()")
        lastID = getID(tx.fetchone())
        # DO SOMETHING USING lasID
        ...
        ...
    def handle_error(self,e):
        log.err(e)

我们下面第二行的lastID对应于第一行中的insert？或者它可以来自任何runInteraction线程？

tx.execute("INSERT INTO User (user_name) VALUES (%s)",(name))
    tx.execute("SELECT LAST_INSERT_ID()")
