Thanks Tom.

I know that logically the schema would be the same, I was just wondering if the underlying physical storage set up by Oracle would in some way be suboptimal in the second case. But if they're identical, that's great, because it means I don't need to worry about patching schemas :0)

Hi,

Does anyone know if the end result of these two statements is actually any different?

CREATE TABLE mytable (

        mycol1 NUMBER,
        mycol2 VARCHAR2(40),
        mycol3 VARCHAR2(30));

and

CREATE TABLE mytable (

        mycol1 NUMBER);
ALTER TABLE mytable ADD (mycol2 VARCHAR2(40)); ALTER TABLE mytable ADD (mycol3 VARCHAR2(30));

Since no data is loaded, will Oracle have create the table in exactly the same way at the end of both two methods?

Thanks,

g
