Question

我正在尝试查看该类型是字母“T”还是数字1-6，用于找到名称和密码的特定数据条目。

  sql = 'SELECT type FROM table name WHERE name = "{}" AND password = "{}"'.format(username, password)

然后在psedocode中我需要类似的东西：

if type =< 5:
      int()
elif type = "T"
      string()

我正在使用python 2.7

这是一个完整的脚本，它将查询mysql数据库，并使用上述逻辑来打印值。我已经包含了python代码以及此测试用例的示例数据库代码。如果您有任何问题，请告诉我。

<强>的Python

import pymysql

connection = pymysql.connect(user='username', passwd='password',
                                 host='localhost',
                                 database='database')

cursor = connection.cursor()

NAME = 'Person_A'
PASSWORD = 'Password_A'
query = ("SELECT * FROM My_TABLE WHERE NAME = '%(1)s' AND PASSWORD = '%(2)s';" % {"1" : NAME, "2" : PASSWORD})


cursor.execute(query)

for item in cursor:

    type = item[0]

    if type.isdigit():
        if int(type) <6:
            print('Type is a number less than 6')
        else:
            print('Type is a number but not less than 6')
    else:
        if type == 'T':
            print('Type is a string == T')
        else:
            print('Type is a string but not the letter T')

<强> MYSQL

CREATE TABLE MY_TABLE (TYPE VARCHAR(255), NAME VARCHAR(255), PASSWORD VARCHAR(255));

INSERT INTO MY_TABLE VALUES ('T','Person_A','Password_A'),('4','Person_A','Password_A'),('7','Person_B','Password_B'),('t','Person_C','Password_C');

如何存储SQL查询的结果并使用它？
