# DButils 为了解决多客户端都需要操作数据库的问题. # import pymysql # from DBUtils.PooledDB import PooledDB # # POOL = PooledDB(creator=pymysql, # mincached=2, # maxcached=5, # maxshared=3, # maxconnections=6, # blocking=True, # maxusage=None, # ping=4, # host=‘172.16.2.106‘, # port=3306, # user=‘root‘, # password=‘123456‘, # database=‘anec‘, # charset=‘utf8‘ # ) # # coon = POOL.connection() # cursor = coon.cursor(cursor=pymysql.cursors.DictCursor) # info_msg = { # ‘cx‘:‘select * from text where id=1‘, # ‘cr‘:‘insert into text(id,name,phone,enail) values(2,"alex","123123213","[email protected]")‘ # } # 查询数据 # cursor.execute(‘select * from text ‘) # ret = cursor.fetchall() # 增加数据 # cursor.execute(‘insert into text(id,name,phone,enail) values(2,"alex","123123213","[email protected]")‘) # coon.commit() # # 删除一条数据 # cursor.execute(‘delete from text where id=2‘) # coon.commit() # 修改数据 # cursor.execute(‘update text set phone = 18711068587 where id=1‘) # coon.commit() # cursor.execute(‘select * from text‘) # ret = cursor.fetchall() # coon.close() # print(ret)
