Question

我目前正在开发一款游戏。此游戏将数据存储在sqlite数据库中。我正在使用dataset来管理数据库，所以我不必担心SQL查询。我有一个方法访问数据库以更新播放器信息：

def updatePlayerInfo(channel, info): # Context at https://github.com/DuckHunt-discord/DuckHunt-Discord/blob/master/database.py#L33
    table = getChannelTable(channel)
    table.upsert(info, ["id_"]) 
    # An UPSERT is a smart combination of insert and update.
    # If rows with matching keys exist they will be updated, otherwise a new row is inserted in the table.

此功能适用于几乎所有内容。只有一件事会产生错误：使用munAP_作为列名！（仅存储整数时间戳）其他一些列的工作方式相同，但不受单个bug的影响！引发的例外情况如下：

sqlalchemy.exc.CompileError: Unconsumed column names: munAP_

我已经尝试更改列名（之前是munAP），但它没有改变任何内容！

我还能尝试什么？我怀疑问题出在我的代码中，但也许是数据集故障？

Sqlalchemy使用数据集模块的未使用的列名称
