python读取Excel到mysql

常见问题：

1.数据库密码有特殊字符

使用urllib.parse.quote_plus 编译密码

mysql_engine = create_engine((f"mysql+pymysql://root:%s@10.0.0.2:3306/mydb")%urllib.parse.quote_plus("pass@=aaaa"))

2.设置字段类型

设置特定类型，和指定日期类型

data1 = pd.read_excel("C:/work/20230818***/数据导入.xlsx",dtype={0:"int", 2:"str", 3:"str"},parse_dates=4,5)

eg:

from sqlalchemy import create_engine

import sqlalchemy

import pandas as pd

import urllib.parse

import datetime

from io import StringIO

use this func, you need to change the cancel , which below # change the test or proc env

be sure you have encoded the tag, and truncate the old db data

if name == 'main':

data1 = pd.read_excel("C:/work/20230818***/数据导入.xlsx",dtype={0:"int", 2:"str", 3:"str"},parse_dates=4,5)

set Create_Time

get current time

now_time = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")

data1"Create_Time" = now_time

set special column

data1"Oper_Sign" = 'admin'

change the test or proc env

mysql_engine = create_engine(f"mysql+pymysql://账号名:密码@IP地址:3306/数据库名")

mysql_engine = create_engine((f"mysql+pymysql://root:%s@10.0.0.2:3306/mydb")%urllib.parse.quote_plus("pass@=aaaa"))

data1.to_sql(name='表名', con=mysql_engine, if_exists="append", index=False)

print('done')
