RE: Defining a Primary Key on a "Create Table As" Sentence…

I wondered the same thing a few months back. I came up with something that came close:

CREATE TABLE New_Table (LIKE Reference_Table, PRIMARY KEY (field1))

Of course, this won't work for you, since you are not selecting all columns from the reference table.

Subject: Defining a Primary Key on a "Create Table As" Sentenceâ

Hi,

(Using V5R3)
Just curious, when you define a SQL table based on another table, as in:

----------
CREATE TABLE New_Table AS(
Select field1, field2 FROM Reference_Table
)WITH NO DATA;
----------

How do you define a primary key? Until now, I have always used an ALTER TABLE sentence (in the same script) for adding a primary key, but I was wondering if there would another way to define it (as in writing it inside the CREATE TABLE statement).

Thanks,

Luis.
