我試圖弄清楚如何使用 SQLite3 語句編寫函數，該語句負責提前通知我任何藥物的有效期，假設是 30 天。我做了這樣的事情，但它不能正常工作l1top = Label(fr,text="Number of serie:")l1top.grid(row=0,column=0,padx=20,sticky=E,pady=10)l2top = Label(fr,text="Name of medicine:")l2top.grid(row=1,column=0,padx=20,sticky=E,pady=10)l3top = Label(fr,text="Dose")l3top.grid(row=3,column=0,padx=20,sticky=E,pady=10)l4top = Label(fr,text="Type of medicine")l4top.grid(row=4,column=0,padx=20,sticky=E,pady=10)l5top = Label(fr,text="Packages:")l5top.grid(row=5,column=0,padx=20,sticky=E,pady=10)l5top = Label(fr,text="Bottles:")l5top.grid(row=6,column=0,padx=20,sticky=E,pady=10)l6top = Label(fr,text="Expiry Date:")l6top.grid(row=7,column=0,padx=20,sticky=E,pady=10)def expiry():    conn = sqlite3.connect("pharmacy.db")    cur = conn.cursor()    cur.execute('SELECT date FROM medicine WHERE date <= 30')    matched = [rec[0] for rec in cur]    conn.close()    items = [row for row in tree.get_children() if tree.item(row, 'values')[6] in matched]    tree.selection_set(items)expiry()上面的代碼沒有正確選擇，因為它只根據天匹配，但它不包括小部件 DateEntry（下面）中的整個日期。如何重寫 SQLite 語句，它獲取整個日期并將所有產品與到期日期在 30 天后結束并用紅色突出顯示帶有日期的最后一列 ([6])。e6 = DateEntry(fr,width=12,bg="darkblue",fg="white",year=2020,state="readonly",date_pattern="dd/mm/yyyy",textvariable=six)e6.grid(row=7,column=1,pady=10)
