pyinstaller打包之后无法写入数据到db，报错no such table: helpers

Question

用pycharm运行没问题，但是打包之后会报错。表已经创建了没问题，exe根目录也会生成.db文件

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

先用pycharm运行后，再把生成的.db文件拷贝到exe根目录就好了，但是为什么直接运行exe在根目录生成的.db文件不能用呢，还有怎么才能把依赖文件直接打包呢

    print("Database connected successfully")
    c = conn.cursor()

解决了，用sql查询的时候连接数据库用的不是绝对路径
