Question

sqlite3.OperationalError：靠近“。”：語法錯誤

當我嘗試填寫表格時出現上述錯誤。

終端：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\username\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)
  File "c:\Users\username\Desktop\Store Accounting Software\add_to_dy.py", line 64, in get_items
    c.execute(sql, (self.name, self.Stock,self.CP, self.SP, self.Total_CP, self.Total_SP, self.Assumed_Profits, self.Vendor, self.Vendor_no))
sqlite3.OperationalError: near ".": syntax error

我在這里查找了所有類似的問題，但找不到解決方案。 這是源代碼，我將不勝感激

root = Tk()

b = Database(root)

root.geometry('1366x768+0+0')

root.title("Add to the database")

root.mainloop()

您在 Vendor_no 之后有一段時間

供應商_編號

在這一行：

sql = “插入庫存（名稱、庫存、CP、SP、Total_CP、Total_SP、Assumed_Profits、Vendor、Vendor_No.）值（？，？，？，？，？，？，？，？，？）"

它不需要在那里。
