python3創建表及表數據；

創建表，參考代碼如下；

import pymysql
test=pymysql.connect('localhost','root','root','test1225')
curs=test.cursor()
curs.execute('drop table if exists xixi')
sql="""
create table `xixi`(`names` varchar(255) default null,
`age` int(3) default null,
`income` decimal(8,2) default 0)
ENGINE=InnoDB DEFAULT charset=utf8;
"""
curs.execute(sql)
test.close()

 

 

 

 

 

 

 向表中添加數據；

方式一、

import pymysql
test=pymysql.connect('localhost','root','root','test1225')
curs=test.cursor()
sql="""
insert into `xixi` values('xiaohua',34,888.3)
"""
curs.execute(sql)
test.commit()
test.close()
方式二、#從外部傳入參數

import pymysql
test=pymysql.connect('localhost','root','root','test1225')
curs=test.cursor()
names='張的美'
age=18
curs.execute('insert into xixi(names,age) values("%s",%d)'%(names,age))
test.commit()
test.close()
方式三、錯誤回滾

import pymysql
test=pymysql.connect('localhost','root','root','test1225')
curs=test.cursor()
names='張的美'
age=18
money=888
try:
    curs.execute('insert into xixi values("%s",%d,%f)' % (names, age, money))
    test.commit()
except:
    test.rollback()
    print('執行錯誤，並且已回滾')
test.close()
