Answer 1

DBD::mysql::st execute failed: called with 8 bind variables when 4 are
needed
That error is not generated by the code that you have shown us. Your code contains this:
my $query = 'INSERT INTO student (StudentId,Name,Dept,address,city) VALUES (?,?,?,?,?)';
That SQL query contains five bind points, not four. It's always important to be accurate when reporting these things.
Anyway, the important thing is that the number of bind points is different to the number of values you pass to execute(). And it's pretty simple to see where that problem comes from.
Your first data line is this:
1 Chellappa CSE 22 xx-colony 2nd street coimbatore
And you split that data into the #vals array with this code:
my #vals = split;
With no arguments, split() splits $_ on whitespace (you can read the documentation online).
So, after running that code on that data, you'll end up with eight values in #vals. Those values are:
1, Chellappa, CSE, 22, xx-colony, 2nd, street, coimbatore
So it's clear that your simple split() isn't processing your data in the way that you expect. You'll need to come up with a more sophisticated way to extract your five expected data items from your input record.
Unfortunately, you don't give us any detail on how your input file is structured, so we can't give you any more help on how to fix your problem.
Update: Guessing at what you might want here, the update statement could become something like:
$sth->update(#vals[0 .. 2], join ' ', #vals[3..6], $vals[7]);
But I have no idea how well that will work with other lines of data that might have the whitespace in other places.

Answer 2

Yes it can be done using join(). Since you have all the values separated by space you are getting this problem. If your file is created by you then you can just add comma separated values like (1, Chellappa, CSE, 22 xx-colony 2nd street,coimbatore). This will help you to fetch all the data using split as follows
split(',',).
