如何在 Tkinter 中实现数据库在帧之间的切换？
How to implement a database in Tkinter switching between frames?

miCursor.executemany("INSERT INTO PRODUCTOS VALUES (NULL, ?, ?, ?, ?, ?, ?, ?)", datos)

miConexion.close()
我希望输入产品的名称、标记或商店，并在文本字段中插入与条目匹配的所有产品信息，但它给了我 'OperationalError' 或 'sqlite3.ProgrammingError' .
我觉得问题出在这里
query = entryConsulta.get()
miCursor.execute("SELECT * FROM PRODUCTOS WHERE NOMBRE = ? OR MARCA = ? OR ESTABLECIMIENTO = ?", query)
你的声明接受了 3 个参数，但你只传递了一个
试试看
query = entryConsulta.get()
args = (query,query,query)
miCursor.execute("SELECT * FROM PRODUCTOS WHERE NOMBRE = ? OR MARCA = ? OR ESTABLECIMIENTO = ?", args)
无论如何我认为你必须在更多模块之间解耦你的代码，如果你对这种类型的程序感兴趣我会建议你这是我的

我希望输入产品的名称、标记或商店，并在文本字段中插入与条目匹配的所有产品信息，但它给了我 'OperationalError' 或 'sqlite3.ProgrammingError' .
我觉得问题出在这里
query = entryConsulta.get()
miCursor.execute("SELECT * FROM PRODUCTOS WHERE NOMBRE = ? OR MARCA = ? OR ESTABLECIMIENTO = ?", query)
你的声明接受了 3 个参数，但你只传递了一个
试试看
query = entryConsulta.get()
args = (query,query,query)
miCursor.execute("SELECT * FROM PRODUCTOS WHERE NOMBRE = ? OR MARCA = ? OR ESTABLECIMIENTO = ?", args)
无论如何我认为你必须在更多模块之间解耦你的代码，如果你对这种类型的程序感兴趣我会建议你这是我的 github
的教学工作https://github.com/1966bc/Tkinterlite
快跑;)
