Create Table

Hi All,

I know it is a really single question, but I am without any
reference... Does anyone can help me ?

I have to tables (example): 'seller' and 'sells'

seller:

CodSeller | NameSeller
----------------------
1435 | Mark
2486 | Tim

Sells:

CodSell | CodSeller | Description
---------------------------------
001 | 1435 | xya sfaks
002 | 2486 | sdf sdfsd

So, I can create seller like:

create table seller (codseller integer, nameseller char(35));

My question is how to create 'Sells' and link it with 'Seller', can I
force delete cascades with this relation ?

Thanks in Advance,

See ya,

Marcelo
