請問一下~~我在做SQLite Manager匯入原本的訊息時跳出第二次訊息是SQLiteManager:DROP TABLE IF EXISTS "chat_history"; [ attempt to write a readonly database ]Exception Name: NS_ERROR_FILE_READ_ONLYException Message: Component returned failure code: 0x80520013 (NS_ERROR_FILE_READ_ONLY) [mozIStorageStatement.execute]然後就錯誤...這樣要怎麼用??
