Ok, since you didn't detail the criteria you need to adapt this as required

#!perl
use warnings;
use strict;

my $criteria;
while (<>) {
  next unless /\S/; # skip blank lines
  if (/(Relay access denied|blocked using)/){
    $criteria = $1;
    next;
  }
  if (/\d+\s+(\S+)/ && defined $criteria){
    print "update db $criteria = $1\n";
  } else {
    $criteria = undef;
  }
}
