eval help

I am trying to expand the variable $user in my alias command and tried
several variations of eval but can't seem to get it to work.

The end result should be either:

oracle_user='sudo su - oracle ' or oracle_user='sudo su - oracle1 '


Code:
 
user=$(grep '^oracle:' /etc/passwd | cut -d":" -f1 )
if [ -z "$user" ]
  then
     user=$(grep '^oracle1:' /etc/passwd | cut -d":" -f1 )
     if [ -z "user" ]
     then
         echo "users oracle or oracle1 not found."
      fi
  fi

 
alias -x oracle_user='sudo su - $user '

Any help would be greatly appreciated
