Answer 1

目前还不清楚您想要什么，如果您想从表中获取信息，也许可以通过以下方法达到目的：

exec(conn,'select * from filee')

Answer 2

I think this vector is the raw database representation of the image... Try to reshape it to it's original size and then to draw it:

image(reshape(int8array,height,width));

But since I just see that your dimension of the int8 array is a prime number I wonder whether it can be reshaped in an image...
