在python中：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/9700.html
1. 连接：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/9700.html
import mysql.connector
cnx = mysql.connector.connect(user='scott', password='tiger',
host='127.0.0.1',
database='employees')
cnx.close()2. 查询：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/9700.html
import datetime
import mysql.connector
cnx = mysql.connector.connect(user='scott', database='employees')
cursor = cnx.cursor()
query = ("SELECT first_name, last_name, hire_date FROM employees "
"WHERE hire_date BETWEEN %s AND %s")
hire_start = datetime.date(1999, 1, 1)
hire_end = datetime.date(1999, 12, 31)
cursor.execute(query, (hire_start, hire_end))
for (first_name, last_name, hire_date) in cursor:
print("{}, {} was hired on {:%d %b %Y}".format(
last_name, first_name, hire_date))
cursor.close()
cnx.close()3. 输出到文件（使用当前日期做文件名）文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/9700.html
import time
filename = 'page_list_'+str(time.strftime("%Y%m%d"))+'.txt'
output = open(filename,'w')
output.write(str(page_title).lstrip('(b\'').rstrip('\',)')+"\n")
output.close()这里page_title是上面从数据库中检索出来的字段名。因为输出都是(b'pagename')的格式，所以又做了一些处理，删除了多余的字符。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/9700.html
这样，检索出的内容就可以直接保存到以日期为名字的文件中了。文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/9700.html
