Question

基本上在应用程序中我连接到我的sql数据库并尝试检索用户给出的输入结果AGE，SEX和ADMITTING DIAGNOSIS CODE。

我可以为AGE和SEX提供用户输入并获得所需的结果，但是当我为AGE，SEX和ADMITTING_DIAGNOSIS_CODE我的网页提供用户输入时返回NONE个值。

Python代码：

import MySQLdb
from flask import Flask, render_template, request
from flask.ext.mysqldb import MySQL

app = Flask(__name__)

db = MySQLdb.connect("127.0.0.1","root","","health" )

@app.route("/", methods = ['GET','POST'])
def home():
    return render_template('home.html')




@app.route("/value", methods = ['GET','POST'])
def Authenticate():
    cursor = db.cursor()
    AGE = request.form['AGE']
    SEX = request.form['SEX']
    ADMITTING_DIAGNOSIS_CODE = request.form['ADMITTING_DIAGNOSIS_CODE']
    #DIAGNOSIS_CODE_1= request.args['DIAGNOSIS_CODE_1']

    sql = 'select avg(LENGTH_OF_STAY),avg(TOTAL_CHARGES),(select count(*) from health where AGE = %s and SEX = %s and ADMITTING_DIAGNOSIS_CODE = %s and DISCHARGE_STATUS = "A")/(count(*))*100 as alive,(select count(*) from health where AGE = %s and SEX = %s and ADMITTING_DIAGNOSIS_CODE = %s and DISCHARGE_STATUS = "B")/(count(*))*100 as dead from health where AGE = %s and SEX = %s and ADMITTING_DIAGNOSIS_CODE = %s'

    entries = []
    cursor.execute(sql,(AGE,SEX,ADMITTING_DIAGNOSIS_CODE,AGE,SEX,ADMITTING_DIAGNOSIS_CODE,AGE,SEX,ADMITTING_DIAGNOSIS_CODE,))

    # Fetch all the rows in a list of lists.
    results = cursor.fetchall()
    for row in results:
        entries.append(dict([('avg(LENGTH_OF_STAY)',row[0]),
                             ('avg(TOTAL_CHARGES)',row[1]),
                             ('dead',row[3]),
                             ('alive',row[2])

                             ]))

    return render_template('show_entries.html', entries=entries)

if __name__ == "__main__":
    app.debug = True
    app.run()

HTML CODE：

<html>
<head>
<title> Welcome</title>
</head>
<body>
<h1> Hello World!!!!</h1>
<form action="/value" method="post" enctype ="multipart/form-data">
<div>Enter the Age <input type="text" name="AGE" style="border: 1px solid black"></div>
<div>Enter the Sex <input type="text" name="SEX" style="border: 1px solid black"></div>
<div>Enter the code <input type="text" name="ADMITTING_DIAGNOSIS_CODE" style="border: 1px solid black"></div>



<div><input type="submit" value=" GO"></div>
</form>
</body>
</html>

<html>
<head>
<title> Welcome</title>
</head>
<body>
<form action="/value" method="get" enctype ="multipart/form-data">
<table style="border: 1px solid black">
<tbody>
<tr>
<th width="35%" style="background-color: #CCFFCC; margin: 5px">Length of stay</th>
<th style="background-color: #CCFFCC; margin: 5px">Total charge</th>
<th style="background-color: #CCFFCC; margin: 5px">Alive</th>
<th style="background-color: #CCFFCC; margin: 5px">Dead</th>
</tr>
{% for entry in entries %}
<tr>
<td>{{ entry['avg(LENGTH_OF_STAY)'] }}</td>
<td>{{ entry['avg(TOTAL_CHARGES)'] }}</td>
<td>{{ entry['alive'] }}</td>
<td>{{ entry['dead'] }}</td>
</tr>
{% endfor %}
</tbody>
</table>
</form>
</body>
</html>

输出：

Length of stay  Total charge    Alive   Dead
None                None         None   None
