查询
def select():
conn = pymysql.connect(user='root', passwd='你的密码',
host='localhost', db='test',charset='utf8')
cur = conn.cursor()
cur.execute("SELECT * FROM user")
for r in cur:
print("row_number:" , (cur.rownumber) )
print("id:"+str(r[0])+" name:"+str(r[1])+" password:"+str(r[2]))
cur.close()
conn.close()插入
def insert(name,pwd):
conn = pymysql.connect(user='root', passwd='你的密码',
host='localhost', db='test',charset='utf8')
cur = conn.cursor()
sql= "INSERT INTO user (Name,Password) VALUES ('"+name+"','"+pwd+"')"
print(sql)
sta=cur.execute(sql)
if sta==1:
print('Done')
else:
print('Failed')
conn.commit()
cur.close()
conn.close()更新
def update(name,pwd):
conn = pymysql.connect(user='root', passwd='你的密码',
host='localhost', db='test',charset='utf8')
cur = conn.cursor()
sql= "UPDATE USER SET PASSWORD='"+pwd+"' WHERE NAME='"+name+"'""'"
print(sql)
sta=cur.execute(sql)
if sta==1:
print('Done')
else:
print('Failed')
conn.commit()
cur.close()
conn.close()删除
def delete(name):
conn = pymysql.connect(user='root', passwd='你的密码',
host='localhost', db='test',charset='utf8')
cur = conn.cursor()
sql = "DELETE FROM USER WHERE Name='"+name+"'"
print(sql)
sta=cur.execute(sql)
if sta==1:
print('Done')
else:
print('Failed')
conn.commit()
cur.close()
conn.close()调用函数进行操作即可
