Cmd.exe command line restrictions

Question

I was working on spooling a bat file from an oracle request that was copying content from one place to another,

Now the command that is generated has a length of more than 255 characters, for example

C:> copy x y ( where len (x+y) > 255)

How does this give an error, is there any work to manage such a situation in order to increase this team length?

PS Some paths + file names are longer than 259 characters, to which I found that there are fewer arguments
