Question

我正在尝试将数据插入MYSQL数据库当我尝试我的程序时，出现错误“格式参数不足字符串”。

ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB se
rver version for the right syntax to use near '%s)' at line 1

还有我的代码：

from flask import Flask, render_template, request
import mysql.connector

app = Flask(__name__, static_url_path="", static_folder="static")

mydb = mysql.connector.connect(
  host="localhost",
  user="root",
  password="",
  database="railway"
)
mycursor = mydb.cursor()

@app.route('/')
def index():
    return render_template('index.html')

@app.route('/store',methods=['POST', 'GET'])
def store():
   if request.method=='POST':
      name=request.form['name']
      mycursor.execute("""INSERT INTO railway (name) VALUES (%s)""",(name))
      mydb.commit()
      return "record inserted."
   else:
      return "s"

if __name__ == "__main__":
    app.run(host='0.0.0.0', port=5000)

Answer 1

尝试一下

mycursor.execute(`INSERT INTO railway (name) VALUES (?)`,(name));

Answer 2

mycursor.execute（“”“”插入铁路（名称）值（％s）“”“，％（名称，））您忘记了％
