Simple enough ...
create table MyNewTable as (
  select whatever
    from MyView
)
with data

Open in new window

Hi Bob,

DB2 generally requires that you create the table and populate it in separate steps.  That's a pretty small limitation though.


  CREATE TABLE mytable AS (SELECT * FROM myview) DEFINITION ONLY;

  INSERT INTO mytable SELECT * FROM myview;

You'll have to modify that slightly if the table has an IDENTITY column, and you'll have to reapply any foreign keys, triggers, or constraints that you need.


Good Luck,
Kent

Hi Dave.

'with data'.  When did that come into existence?


(pretty cool)

Hi Kent,

I’m currently using 6.1 (a.k.a. V6R1) on System i (a.k.a. AS/400). From the SQL Reference manuals, I can see that the "WITH DATA" functionality existed in 5.4 (in 2006) and 5.3 (in 2005), but I don’t see that functionality listed in the 5.1 manual (from 2001).

I no longer have the 5.2 manual, so I can't check that one.

I don't know how that translates to DB2 on other platforms, though.

HTH,
DaveSlash
