Question

我正在使用python 3 tkinter和sqlite 我在tkinter Text Widget中有数据，然后需要拆分并将其保存在数据库表中，这是我的代码尝试

data = txtReceipt.get("4.0" ,"end")

 for line in data.splitlines()[2:-2]:

     no = line.split()[2:3]
     name = line.split()[1:2]
     price = line.split()[3:4]
     series = line.split()[:1]
     print(no)
     c.execute("INSERT INTO  billed_items(item_name,billed_qty,price,item_bill_series) VALUES(?,?,?,?)",(name),(no),(price),(series))
     conn.commit()

但是我收到此错误消息TypeError: function takes at most 2 arguments (5 given) 任何帮助请当我尝试读回文本小部件时，也在这里

    su=c.execute("SELECT * FROM billed_items")
    for row in su:
            text = str(row)
            txtReceipt.insert("end",str(row[0])+"  "+str(row[1])+'\t\t'+str(row[2])+'\t'+"  "+str(row[3])+"\n")

在那里，它只读取表的最后一行，我不知道为什么他不能读取所有行

Answer 1

需要在元组中提供值。试试这个

query = ("INSERT INTO  billed_items(item_name,billed_qty,price,item_bill_series) VALUES(?,?,?,?)")
c.execute(query,((name),(no),(price),(series))
conn.commit()

// sqlite3.OperationalError: near "%": syntax error?

python sqlite插入错误
