--w_blob.py  写入blob




import sys
import pymysql
import os


path = "./"


fp = open("/alidata/PG01.jpg", 'rb')
img = fp.read()
fp.close()


database = pymysql.connect(host="localhost", user="root", passwd="root", db="qinxi")
cursor = database.cursor()
sql = "INSERT INTO tb_test (nameBlob) VALUES  (%s);"
args = (img)
cursor.execute(sql, args)
database.commit()
cursor.close()
database.close()


print("============")
print("Done! ")




--r_blob.py 读取blob


import pymysql as mdb
import sys


conn = mdb.connect(host='localhost',user='root',passwd='root',db='qinxi')
cursor = conn.cursor()
cursor.execute("SELECT nameBlob FROM tb_test LIMIT 1")
fout = open('PG333.jpg','wb')
fout.write(cursor.fetchone()[0])
fout.close()
cursor.close()
conn.close()
