You are getting confused about shell command line quoting.  The
$ODSRELEASE is getting expanded by *your* shell inside the double
quotes and the sub-shell is never even getting the query.  It is only
seeing an empty echo command.

Try this instead.

  su - test -c 'echo $ODSRELEASE'

or

  su - test -c "echo \$ODSRELEASE"

Use 'echo' again to see what the expansion of the command line looks
like.

  echo su - test -c "echo $ODSRELEASE"
  echo su - test -c 'echo $ODSRELEASE'
  echo su - test -c "echo \$ODSRELEASE"
