I have few classes and I want to **create all possible combinations.**

Class table
-----------

```
ColA
A
B
C
D
E

```

Output (not that if I have A,B as output I don't want B,A as well, etc.)

```
ColA    Col2 
A        B
A        C
A        D
A        E
B        C
B        D
B        E
C        D
C        E
D        E

```

I don't want to use cursors.
