连接MySQL等数据库
- 其他数据库格式与之一样，import包不同而已，比如sqlserver是pymssql
from pymysql import connect def exeSqlRes(server,user,password,database,sql): conn = connect(server,user,password,database) cursor = conn.cursor() cursor.execute(sql) list1 = cursor.fetchall() # get count try: print("业务日期 ：%s\n收费总金额：%s\n" % (list1[0][0],list1[0][1])) except: print("日期选择错误，请确认该天有数据\n") conn.close() exeSqlRes('xx.xx.xx.xx','xx','xx','xxx','select now()')
