pip install pymysql

 

import pymysql
# 打开数据库连接
db = pymysql.connect("localhost","root","12345","centralsystem" )
# 使用 cursor() 方法创建一个游标对象 cursor
cursor = db.cursor()
# 使用 execute()  方法执行 SQL 查询
cursor.execute("SELECT VERSION()")
# 使用 fetchone() 方法获取单条数据.
data = cursor.fetchone()
print("Database version : %s " % data)





sql = "SELECT * FROM t_user WHERE USER_ID > %d" % (1)

try:
   # Execute the SQL command
   cursor.execute(sql)
   # Fetch all the rows in a list of lists.
   results = cursor.fetchall()
   for row in results:
      #print (row)
      id = row[1]
      userName = row[2]
      RealName = row[3]
      PassWord = row[4]
      Email = row[5]
      Mobil = row[6]
      # Now print fetched result
      print ("userName,RealName = %s %s,PassWord = %s, Email= %s,Mobil = %s" % \
             (userName, RealName, PassWord, Email, Mobil ))
except:
   import traceback
   traceback.print_exc()
   print ("Error: unable to fetch data")




# 关闭数据库连接
db.close()
