From guy.hammond@avt.co.uk Fri, 17 Aug 2001 07:58:36 -0700 From: "Guy Hammond" Date: Fri, 17 Aug 2001 07:58:36 -0700 Subject: RE: table create vs alter Message-ID: MIME-Version: 1.0 Content-Type: text/plain 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) g -----Original Message----- Sent: Friday, August 17, 2001 2:26 PM To: Multiple recipients of list ORACLE-L g, why not try it???? the answer is - no difference. Tom Mercadante Oracle Certified Professional -----Original Message----- Sent: Friday, August 17, 2001 6:01 AM To: Multiple recipients of list ORACLE-L 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?
