源程式如下
import pymysql
connect=pymysql.Connect(
host='localhost',
port ='3306',
user ='root',
passwd='123456',
db='18年6月資料明細',
charset='utf8'
)
#連接游標
cursor=connect.cursor()
#sql陳述句
sql="select 客戶明細_18年6月.客戶 from 客戶明細_18年6月 where 客戶明細_18年6月.組別='%s'"%('B-3楊忠葵')
#執行sql陳述句
cursor.execute(sql)
results=cursor.fetchall()
for r in results:
print("r")

uj5u.com熱心網友回復：
試下這種方式:
config = {
'host':'127.0.0.1',
'port':3306,
'user':'root',
'password':'xinxin2333',
'database':'trade_ms',
'charset':'utf8mb4',
'cursorclass':pymysql.cursors.Cursor,
}
# 連接資料庫
connection = pymysql.connect(**config)

你好，port后面跟的是數字，你給的字串，修改port=3306 而不是port="3306"轉載請註明出處，本文鏈接：https://www.uj5u.com/shujuku/84064.html
