If the table changes, one can use the ALTER TABLE command; I used to do that. Personally, though, I now create a new table in a test library, use the CPYF command to push the data records, then a DLTF / CRTDUPOBJ. I replace the old DDL source with the new layout's source.

ok, I think that answers my last question, how do I 'run' this.
The RUNSQLSTM reads the source file specified and executes the SQL commands.
I guess you could say that the DDL text file in a sense is DDS and CRTPF
combined into one.

In this location, we store a series of statements in a source member,
that create the file object and apply the label text and column
headings. This "source" is then "compiled" with the RUNSQLSTM command.
Here's an abridged sample:
CREATE TABLE PGPAPPLOGR (
JOB_NAME for column LOGJOBN
CHAR(10)
CCSID 37
not null default '' ,
JOB_USER for column LOGJOBU
CHAR(10)
CCSID 37
NOT NULL DEFAULT '' ,
JOB_NBR for column LOGJOB#
CHAR(6)
CCSID 37
NOT NULL DEFAULT '' ,
EVENT_TS for column LOGEVTTS
TIMESTAMP
NOT NULL ,
EVENT_TYPE for column LOGEVTTYP
CHAR(10)
CCSID 37
NOT NULL default '',
EVENT_MSG for column LOGEVTMSG
CHAR(80)
NOT NULL default '');
RENAME TABLE PGPAPPLOGR TO PGPAPPLOG;
LABEL ON COLUMN PGPAPPLOG
( JOB_NAME IS 'Job ID Name ' ,
JOB_USER IS 'Job ID User ' ,
JOB_NBR IS 'Job ID Number ' ,
EVENT_TS IS 'Event Timestamp ' ,
EVENT_TYPE IS 'Event Type ' ,
EVENT_MSG IS 'Event Message ');

Subject: Confused about DDL and DDS
I have been searching through the archives and the web.
I want to create a data base file using DDL. Is DDL just a text file
created with PDM with a CREATE statement in it? I did not see any
examples anywhere except CREATE statements. I never saw the equivalent
of DDS for the CREATE to look at.
I do not see a source type DDL in PDM.
Signed, confused in Ebensburg...
