Another method of solving the original question using getline

Code:
$cat awkfile
BEGIN { pid="" }

$2=="174" { pid=$3 }

END {
   if (pid != "") {
      tmp="sed -n /"pid"/p file"
      while ((tmp | getline) > 0)
         print
      close(tmp)
   }
}
$

Code:
$ awk -f awkfile tempfile.txt
t2589vg 8888 11234 -ksh
mqsiadm 174 8888 -ksh
$
