python3存图片到数据库中并查询（附送一张张查看图片）

import pymysql
from PIL import Image
import os, time

# 打开图片存放到内存中

fp.close()

cursor = database.cursor()
#cursor.execute('ALTER TABLE photo CONVERT TO CHARACTER SET utf8mb4;')
#
i = 0
sql = "INSERT INTO photo(id, image) VALUES(%s, %s);"
img = str(img)
print(len(img))
print('----------------------')
# 图片存放到数据库
print(cursor.execute(sql, [i, img]))
database.commit()

print("Insert Done! ")
print("============")
print("Start Query ")

    print(i)

print("共查询到：", cursor.rowcount, "条数据")
