hi, i'm new with mysql and i have a problem that i don't undertand what happend.
i'm using mysql workbench 5.2.37

delimiter [;
create trigger trans_back_up1
after insert on trans_tabla1
for each row
begin
delete from trans_tabla_inter;
insert into trans_tabla_inter(nombre_tabla) values ('trans_tabla1');
end;
[;

delimiter [;
create trigger trans_back_up2
after insert on trans_tabla_inter
for each row
begin
insert into trans_tabla_back_up
select *
from trans_tabla1;
end;
[;

the problem is that when i insert into trans_tabla1, 5 rows from a file, i have the 5 rows fine on trans_tabla1 but on the table trans_tabla_back_up i have duplicates, i have 5 copies of the first row, 4 copies of the second, 3 of the third, 2 of the fourth , and 1 of the fifth.
