Answer 1

您可以使用以下步骤使用 python 检索关系数据库的数据:

    #!/usr/bin/python
    # import the desired package
    import MySQLdb

    # Open database connection
    db = MySQLdb.connect(hostaddress,user,password,db_name)

    # prepare a cursor object using cursor() method
    cursor = db.cursor()

    # execute SQL query using execute() method.
    cursor.execute("SELECT COUNT(addr) FROM list_table WHERE addr = '192.168.1.1'")

    # Fetch a single row using fetchone() method and store the result in a variable. 
    data = cursor.fetchone()

  #OR use fetchall() method to fetch multiple rows and store the result in a list variable. 
 data = cursor.fetchall()

    print data

    # disconnect from server
    db.close()
