Map table without pk

Hi,
I'm sorry for my English, but I can't speak English very well.

I must map a particular table: there isn't a pk!
It is a log table!
I've try to map the table but <id> is required!

How can I map this table?
Or must I alter the table? Must I add a Pk?

Thanks everybody :-)
Mary

Every table in a database has a PK. If none of your columns (or a subset of your columns) distinguishes uniquely a row, the combination of all the columns will be the PK.

So, yes, you need a PK, but you can stablish it as you wish.

Hope it helps.

Thanks very much Hector
