在嘗試使用 flask 應用程序插入 mysql 數據庫時，並非所有參數都在 SQL 語句中使用

Question

error image Actually I am trying to create flask web application in which, I wanted to store my input values from html webpage into MySQL database, but am getting error as Not all parameters were used in the SQL statement when calling my insert function. 請找到我的代碼

import mysql.connector as conn

def insert_records(name,email,location,salary,band):
    con=conn.connect(host='localhost',user='root',password='my password',database="my database")
    cur=con.cursor()
    sql="""insert into emp1.emp(Name,Email,Location,Salary,Band) values (%s,%s,%s,%d,%s)"""
    val=(name,email,location,salary,band)
    cur.execute(sql,val)
    con.commit()
    con.close()

Answer 1

您需要對文檔中的每個參數使用 %s - 他們將 %s 用於字符串、整數、日期時間等。
