Generally passing a hash to a subroutine is not good.
You may try to pass a hash's reference to the subroutine,this get things more
clear.
Just do:
&StudentInfo::updateStudent($conn,\%addNewStudentHash,$classsId,$schoolName);
Here \%addNewStudentHash is the reference for hash %addNewStudentHash.
(why need to pass a reference instead of a hash?because a reference is a
scalar,while a hash appear as a list.You don't know the hash list's length,so
you can't control the arguments' order exactly.)

Ok here in the subroutine you receive the hash's reference.do:
my ($conn,$addNewStudentHash_ref,$classsID,$schoolName) = @_;
my %addNewStudentHash = %$addNewStudentHash_ref; # re-access the original hash
Hope this helps.
