1、插入操作:
1 #!/uer/bin/env python 2 # -*- coding:utf-8 -*- 3 4 import MySQLdb 5 6 conn = MySQLdb.connect(host=‘192.168.1.100‘,user=‘root‘,passwd=‘123456‘,db=‘oldb‘) 7 8 cur = conn.cursor() 9 10 reCount = cur.execute(‘insert into students(Name,sex,age,tel) values(%s,%s,%s,%s)‘,(‘alex2‘,‘man‘,19,‘18923143‘)) 11 # reCount = cur.execute(‘select * from students;‘) 12 13 conn.commit() 14 cur.close() 15 conn.close() 16 print(reCount)
输出信息:
3
2、查询操作
1 #!/uer/bin/env python 2 # -*- coding:utf-8 -*- 3 4 import MySQLdb 5 6 conn = MySQLdb.connect(host=‘192.168.1.100‘,user=‘root‘,passwd=‘123456‘,db=‘oldb‘) 7 8 cur = conn.cursor() 9 10 # reCount = cur.execute(‘insert into students(Name,sex,age,tel) values(%s,%s,%s,%s)‘,(‘alex4‘,‘man‘,29,‘18923143‘)) 11 reCount = cur.execute(‘select * from students;‘) 12 13 14 print(cur.fetchone())---------------------------------- 15 print(cur.fetchall()) #取出所有数据
----------------------------------
16 print(cur.fetchmany(3)) #指定3 条数据
输出信息:
(1L, ‘alex‘, ‘man‘, 18, ‘151515151‘)
------------------------------------
((1L, ‘alex‘, ‘man‘, 18, ‘151515151‘)
(2L, ‘alex2‘, ‘man‘, 19, ‘18923143‘)
(3L, ‘alex2‘, ‘man‘, 19, ‘18923143‘))
-------------------------------------

3、批量插入数据
1 #!/uer/bin/env python 2 # -*- coding:utf-8 -*- 3 4 import MySQLdb 5 6 conn = MySQLdb.connect(host=‘192.168.1.100‘,user=‘root‘,passwd=‘123456‘,db=‘oldb‘) 7 8 cur = conn.cursor() 9 10 li = [ 11 (‘tommite‘,‘man‘,29,‘189231432‘), 12 (‘kendi‘,‘man‘,26,‘189231433‘), 13 (‘lili‘,‘man‘,19,‘189231434‘), 14 ] 15 16 reCount = cur.executemany(‘insert into students(Name,sex,age,tel) values(%s,%s,%s,%s)‘,li) 17 18 conn.commit() 19 cur.close() 20 conn.close() 21 print(reCount)
输出信息:
3
