[SOLVED] how to calculate the sum of the first 100 integers in MySQL with a while loop – Stack Overflow

Issue

This Content is from Stack Overflow. Question asked by wiam leo

I must find the sum of the first 100 natural numbers. 1+2+3+…+n, and so on. While using “while loops”.

delimiter $

create procedure `calcul`.somme()

begin

declare s int default 0;
declare i int default 1;

while(i<=100) do
    set s := s+i;
    set i := i=1;
end while;
select s;

end;
$
call `calcul`.somme()



Solution

The query is taking too long and the engine is timing out.

You can edit the SQL Editor preferences in MySQL Workbench:

  1. In the application menu, select Edit > Preferences > SQL Editor.
  2. Look for the MySQL Session section and increase the DBMS connection read time out value.
  3. Save the settings, quite MySQL Workbench and reopen the connection.
