Error 1064 in stored procedure - mysql

I'm not an expert with MySQL and I've problems with this Stored Procedure.
I'm trying to do the SP with conditions but I don't know what is wrong here, I have a mistake:
Error Code: 1064. You have an error in your SQL syntax; check the

Problem is in the part as pointed below, where you are trying to declare a local variable inside IF .. ELSE block. You can set the variable inside if .. else block but you should declare them in the beginning
if varJefe=1
then
declare done int default 0; <-- Here
You should declare the variable at the beginning like
create procedure getListPrsn(IN idEquipo INT, IN tipo char, IN Puesto INT)
begin
declare varJefe int;
declare eqpSupJefe int;
declare done int default 0; <-- declare it here

A DECLARE has to be at the beginning of a BEGIN ... END block. You can either move them to the beginning of the procedure (the variable declaration has to be before the cursors, the handler declaration has to be after them):
delimiter $$
create procedure getListPrsn(IN idEquipo INT, IN tipo char, IN Puesto INT)
begin
declare varJefe int;
declare eqpSupJefe int;
declare done int default 0;

inner join tblpuesto on (tblequipo.EqpID=tblpuesto.PtoEqp)
inner join tblplaza on (tblpuesto.PtoID=tblplaza.PzaPto)
inner join tblpersona on (tblplaza.PzaPrsn=tblpersona.PrsnID)

declare equipoSuperiorDeMiJefe cursor for select tblequipo.EqpEqpSup
from tblequipo
inner join tblpuesto on(tblequipo.EqpID=tblpuesto.PtoEqp)
where tblpuesto.PtoID=Puesto;
declare continue handler for sqlstate '02000' set done=1;
if tipo="jefe"
then
open jefeONo;
begin
repeat
fetch jefeONo into varJefe;

end;
close jefeONo;

call getLider(eqpSupJefe);
else
if varJefe=0
then
call getLider(idEquipo);
end if;
end if;
end if;
end $$

or put them after the BEGIN statements before the REPEAT statements:

I fix my SP
We have to check the declaration order
1.- variables
2.- conditions
3.- cursors
4.- handlers

my procedure is executing twice, what is the problem?

I have buffet table and I want to replace an ingredient with another, but my cursor replacing twice, and I get wrong answer.
Note: I'm using MySQL Workbench v 8.0.30

in new_ingred text)

declare continue handler for sqlstate '02000'
set d=1;
declare continue handler for sqlstate '23000'
set d=1;
open get_cur_ingred ;
lbl: loop
if d=1 then
leave lbl;
end if;
if not d=1 then
fetch get_cur_ingred into c_id ;
select insert((select ingredients from buffet where id=c_id ),
(select locate(old_ingred,ingredients) from buffet where id=c_id ),
(select length(old_ingred)),new_ingred) into res;
update buffet

MySql stored procedure error [ERROR 1338 (42000): Cursor declaration after handler declaration]

I am reading an article on stored procedures and this is the code:
delimiter //
create procedure largest_order(out largest_id int)
begin
declare this_id int;
declare this_amount float;
declare l_amount float default 0.0;
declare l_id int;
declare done int default 0;
declare continue handler for sqlstate '02000' set done = 1;
declare c1 cursor for select orderid, amount from orders;
open c1;
repeat
fetch c1 into this_id, this_amount;
if not done then
if this_amount > l_amount then
set l_amount=this_amount;
set l_id=this_id;
end if;
end if;
until done end repeat;
close c1;
set largest_id=l_id;
end
//
delimiter ;
I am using a simple database named "mydatabase". After running the above code it gives me this error: ERROR 1338 (42000): Cursor declaration after handler declaration
What is wrong and how can I fix it?
This is my first time working with stored procedures.
Per MySql docs:
Cursor declarations must appear before handler declarations and after
variable and condition declarations.
So I updated the code as follows:
delimiter //
create procedure largest_order(out largest_id int)
begin
declare this_id int;
declare this_amount float;
declare l_amount float default 0.0;
declare l_id int;
-- 1. cursor finished/done variable comes first
declare done int default 0;
-- 2. the curser declaration and select
declare c1 cursor for select orderid, amount from orders;
-- 3. the continue handler is defined last
declare continue handler for sqlstate '02000' set done = 1;
open c1;
repeat
fetch c1 into this_id, this_amount;
if not done then
if this_amount > l_amount then
set l_amount=this_amount;
set l_id=this_id;
end if;
end if;
until done end repeat;
close c1;
set largest_id=l_id;
end
//
delimiter ;
And now works fine.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Declare mycur cursor for
select TOKENNUMBER,APPOINTMENTTIME,ADJ' at line 33
(0 ms taken)
Declarations must follow a certain order.
It is not allowed to declare a cursor or an event handler in the middle of your procedure. Yes, the error message is misleading to say the least. You must declare the mycur cursor at the beginning of a BEGIN ... END block.
You could either move the second cursor declaration to the beginning of your procedure, or nest a BEGIN ... END block at an appropriate location.
