$(*) is the same as `*`, that is, it is subsituted by the shell with the
standard output of the command enclosed.

The return value the last command executed by the shell is held in $?,
and the success or failure of a command can be used where a conditional
statment is used.

What you want is

if sftp2 -B ftpcommands db2admin at cq7092; then
  echo "file transfer was successful"
else
  echo "file transfer failed"
fi


Or if you wanted to be wierd

sftp2 -B ftpcommands db2admin at cq7092 && {
  echo "file transfer was successful"
} || {
  echo "file transfer failed"
}
