我寫的代碼是:插入變量
import sqlite3
def insert_product(product):
with sqlite3.connect("main.db") as db:
cursor = db.cursor()
sql=("insert into Products(CatID,Name,Qty,Price)values(?, ?, ?, ?)", (ID,Name,Qty,Price))
cursor.execute(sql,product)
db.commit()
if __name__ == "__main__":
ID= int(input("enter the CatID of the product:>> "))
Name = input("Enter the name of the Product you want to inssert: >>")
Qty = int(input("Enter the quantity of the stock available: >>"))
Price = int(input("Enter the price of the product: >>"))
product = (ID,Name,Qty,Price)
insert_product(product)
我想用ID的輸入值,名稱,數量及價格,以插入數據庫中的值,但它給了我這個錯誤:
File "C:\Users\Admin\OneDrive\sql\insert_product.py", line 6, in insert_product cursor.execute(sql,product) ValueError: operation parameter must be str
這消除錯誤,但沒有做任何事情 –
該數據庫的代碼是http://www.heypasteit.com/clip/38QJ –
@SaqibMalik你是什麼意思,它不會做任何事情?你是否在用戶輸入後檢查數據庫,並通知用戶的條目添加到數據庫?爲我工作.. – davedwards
