python2使用MySQLdb模块进行连接mysql数据库进行操作;python3则使用pymysql模块进行连接mysql数据库进行操作;两者在语法上有稍微的差别,其中就包括查询结果包含字段名,具体例子如下:
python2:
import MySQLdb
conn = MySQLdb.connect(host=‘127.0.0.1‘,user=‘root‘,passwd=‘root‘,db=‘adu‘)
cur = conn.cursor(cursorclass=MySQLdb.cursors.DictCursor)
sql = ‘select * from test1‘
reCount = cur.execute(sql)
nRet = cur.fetchall()
cur.close()
conn.close()
print(nRet)
print(reCount)
pytnon3:
import pymysql
conn = pymysql.connect(host=‘127.0.0.1‘,user=‘root‘,passwd=‘root‘,db=‘adu‘)
cur = conn.cursor(cursor=pymysql.cursors.DictCursor)
sql = ‘select * from test1‘
reCount = cur.execute(sql)
nRet = cur.fetchall()
cur.close()
conn.close()
print(nRet)
print(reCount)
