I have a list of data that I would like to order descending but i would like to start out with numbers then go to strings.   

Example of what I'm looking for.

```
43a
34a
22a
11d
ztc
xtc
ytc

```

but if you just do 

```
SELECT list FROM table ORDER BY list DESC;

```

It outputs the list like this.

```
ztc
xtc
ytc
43a
34a
22a
11d

```

Is there a way to do this?
