import pymysql
# 打开数据库连接
db = pymysql.connect("localhost","root","root","db_test01" )
# 使用cursor()方法获取操作游标
cursor = db.cursor()
# SQL 查询语句
sql = "SELECT * FROM EMPLOYEE \
WHERE INCOME > '%d'" % (1000)
try:
# 执行SQL语句
cursor.execute(sql)
# 获取所有记录列表
results = cursor.fetchall()
for row in results:
fname = row[0]
lname = row[1]
age = row[2]
sex = row[3]
income = row[4]
# 打印结果
print ("fname=%s,lname=%s,age=%d,sex=%s,income=%d" % \
(fname, lname, age, sex, income ))
except:
