Answer 1

I don't see any Declare_sym in your posted query but your SQL code do have syntax error as pointed below. Not sure if those are just typo while posting the question
select Count(*) into regno_Count
fro students_info
^...... should be *from*
update students_info
set firstname = in_fNM,
middlename = in_mNM,
lastname = in_lNM, <----- remove this extra *,* here
where regno = in_regno ;
Change your procedure body to be like below
delimiter #
create procedure StudentUpsert
(in in_regno int ,
in in_fNM varchar(50),
in in_mNM varchar(50),
in in_lNM varchar(50))
begin
declare regno_Count int ;
select Count(*) into regno_Count
from students_info;
if regno_Count > 0 then
update students_info
set firstname = in_fNM,
middlename = in_mNM,
lastname = in_lNM
where regno = in_regno ;
else
insert into students_info
values (in_regno , in_fNM , in_mNM , in_lNM);
end if;
end#
