Table without primary key

Hi,

Why don't you just add a primary key? If you don't have a primary key, how do you find entries in the database?

Why don't you just add a primary key?

I did not create DB. I can't modify it, only use.

If you don't have a primary key, how do you find entries in the database?

I use SQL :slight_smile:

Since I don't know the answer, I'll ask Step's question another way: why not ask the DBA to add a primary key?

I use SQL :slight_smile: You can create table without PK and you will be able to get data :slight_smile:

Of course. I think what Step wanted to know was what criteria do you use to find unique rows?

Oops. In my earlier reply, I meant to reference Jens' questions instead of Step's. I'm sorry for any confusion.
