有人可以告訴我什麼是我的SQLite查詢錯？它的allways告訴我'plugins._id'這個列不會存在，但我確定它確實存在。我正在讀這個查詢上面兩行。SQL RawQuery告訴我列不存在
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});
在此先感謝。
