if use function once, works properly. if make loop down below, 4 lines of commented code, code malfunctions. can't figure out why return t or f every other number after initial value. asterisks in parenthesis of write , read doesn't show here reason. program prime integer :: n = 0, = 1,x = 0 logical :: ip write (*,*) "enter number:" read (*,*) n !do while ( n < 1000) ip = isprime(n) write (*,*) ip, n !n = n + 1 !end read(*,*) x contains function isprime(n) logical :: isprime integer, intent(in) :: n isprime = .true. if (n == 2) write (*,*) n else while (i <= (n/2)) = + 2 if (mod(n,i) == 0) isprime = .false. end if end end if return end function isprime end program prime you're forgetting reset i 1 during each call isprime . the first time isprime called, i=1 top of program main . however, i incremented during first isprime call other 1 second call starts i/=0 . note because isprime contai...

having table name transitions , i want change values of rows after update made. i'm using following trigger, changes row i'm making update to. create trigger signaturetrigger before update on `transactions` each row begin set new.signature = '288'; end i'm trying change rows signature = 288 , how can modify trigger in order archieve that? thought using for each row enough. thanks in advance. you can use after update trigger update statement: create trigger signaturetrigger after update on `transactions` each row begin update transactions set new.signature = '288'; end; this seem strange thing do, however. consider alternative: add updatedat column table , update signature in row. then, when want recent signature use: select signature transactions order updatedat desc limit 1; an index on transactions(updatedat, signature) make quite speedy. and, update go much, faster updating rows.
