有人可以告诉我我的SQLite查询有什么问题吗？它总是告诉我列'plugins._id'不会存在，但我确信它确实存在。我在这个查询上面只读了两行。
return mDatenbank.rawQuery("SELECT plugins._id, plugins.name, plugins.number,
plugins.device_id, connections.plugin1, connections.plugin2, addedDevices._id,
addedDevices.name, connections._id FROM connections INNER JOIN (plugins INNER JOIN
addedDevices ON plugins.device_id = addedDevices._id) ON connections.plugin2 =
plugins.device_id OR connections.plugin1 = plugins.device_id WHERE connections.plugin1=?
OR connections.plugin2=?;", new String[] {PlugInName, PlugInName});
提前致谢。
