我卡住了。我一直试图在mysql数据库中插入一个pdf文件，但我做不到。我试过mysql.connector和mysqldb类。我也会犯同样的错误。我读过很多关于这个问题的帖子。我试过逗号，也试过变量。这是我的代码和错误；

import mysql.connector

db = mysql.connector.connect(host="127.0.0.1", user='root', password='masatablo', db='yukleme')

c  = db.cursor()

acilacak_dosya = open("bizim.PDF", "rb")

yuklenecek_dosya = acilacak_dosya.read()

c.execute ("INSERT INTO pdfler (cizim) VALUES(%s)" %(yuklenecek_dosya))

db.commit()

db.close()

ERROR with mysql.connector:
