RE: Retrieving SYSCOLUMNS field in CLLE -- MIDRANGE-L

Vern,

There are many system administration tasks that could be done if the things
Dan is referring to could be done in CL. Many Sysadmins have left RPG
and/or COBOL behind and don't want to deal with it. You're correct of
course it's not hard, but it is if you don't write RPG but a couple times a
year. Also not all sysadmins came from a development background so they
would not have the education in those things in the first place. No I'm not
arguing that Sysadmins should not learn it, but it's going to be stretch
for many.

Hi Dan

Seems this is another prime example of why one does NOT use CL for this kind
of thing - it is all so easy in RPGLE. And I suspect CL won't support things
like LOBs on DCLF any time soon.

I suggest using DECLARE CURSOR in RPGLE - eezee-peezee!

I have a CREATE TABLE in a CLLE program that queries SYSCOLUMNS for
one record (never more than one record, could be zero) and I need the
value from one field.

I tried DCLF SYSCOLUMNS and did an override to the file created by
CREATE TABLE, but upon doing a RCVF, I got CPF428A (Open failed
because "The format for file TMPSYSCOLS contains one or more large
object fields and the open request did not indicate that large object
fields could be processed by the user of the open."

I did specify AlwGraphic(*Yes) on the DCLF because it wouldn't compile
without it. But I see no option on DCLF or RCVF to process or ignore
"large object fields".

So, I am changing the query in the aforementioned CREATE TABLE to
select the one field I need. Now the table has the field, but since
it is created on the fly, I have nothing at compile time for a DCLF,
and I'd really like to avoid creating a permanent file for this. It
would just be freaking useful to be able to do a SELECT INTO in CL like we

can in RPG.

Don't know if the "late Friday after a long week brain fry" is
affecting my memory, but is there a way to do this without creating a
permanent file needed to compile the program?

FWIW: We're on v7r1 with the latest TRs.
