python连接mariadb数据库写入数据
作者:互联网
1、逻辑
根据每日生成的一个全网设备信息:设备名、厂商、设备型号、IP、版本、存活时间自动先生成一个.CSV文件,python通过pymysql库连接数据库将设备基础信息csv文件写入数据库(逐条写入)。
import pymysql
def main():
try:
csv_file_path='/home/zhangli/sw_list.csv'
file = open(csv_file_path, 'r',encoding='utf-8')
reader = file.readline()
b = reader.split(',')
colum = ''
for a in b:
colum = colum + a + ' varchar(255),'
colum = colum[:-1]
#定义table名字
table_name = 'ETCD'
#定义要插入的数据
#ata = "LOAD DATA LOCAL INFILE '%s' INTO TABLE %s FIELDS TERMINATED BY ',' LINES TERMINATED BY '\\r\\n' IGNORE 1 LINES" % (csv_filename,table_name)
#连接数据库
conn = pymysql.connect(host='localhost',port=3306,user='root',passwd='admin123',db='NET',charset='utf8')
#创建游标对象
cursor = conn.cursor()
#定义数据库
database='NET'
#创建table
create_table = 'create table if not exists ' + table_name + ' ' + '(' + colum + ')' + ' DEFAULT CHARSET=utf8'
#执行
cursor.execute('drop table %s' % table_name)
cursor.execute('use %s' % database)
cursor.execute(create_table)
#创建sql语句
for line in file:
line=line.replace("\n","")
f_read=line.split(',')
if f_read[0] == 'sw_name':
continue
else:
sw_name=f_read[0]
ip=f_read[1]
data_info=' values('+"\""+sw_name+"\""','+"\""+ip+"\""')'
sql = 'insert into '+table_name+data_info
cursor.execute(sql)
#提交事务
conn.commit()
cursor.close()
conn.close()
except Exception as err:
print(err)
main()
