Re: How to merge 2 customers into 1?

Note that SQL delete will work two different ways depending upon the
use of commitment control or not.

From the v5r4 manual:

DELETE Performance: An SQL DELETE statement that does not contain a
WHERE clause will delete all rows of a table. In this case, the rows
may be deleted using either a clear operation (if not running under
commitment control) or a change file operation (if running under
commitment control). If running under commitment control, the deletes
can still be committed or rolled back. This implementation will be
much faster than individually deleting each row, but individual
journal entries for each row will not be recorded in the journal.

Charles is right. IIRC, since V5R3 a DELETE without a where clause, when the
table is not being used by any other process (ie, the DELETE can do a
exclusive lock to the table) , it is the same as a CLRPFM which, AFAIK, is
not recoverable using journals...

It seems that Rob's post would need some minor changes. Nevertheless, I
still think is a nice intro.

Rob: Would you mind if I use your post as a base for a small article for the
midrange wiki?

Nope,
16 -F OP - File Open
17 - F  CL - File Close

Now
15 - F CR - File Clear

is another story. :)

That's from either CLRPFM or an SQL DELETE without a where clause.

 A while back Rob Berendt wrote this wonderful intro to
Journals:

Check it. I think you will find it worthwhile...

Hey, I just got into journalling! See, if you don't post, you don't

learn.

Trouble is, I just ran the sql bit from hell, there are no records left

but nothing in the journal except :

Opt   Séquence   Code   Type   Objet   Bibliothèque   Travail   Heure
            15   F     CR   ARHDMN      FOXWELL     DFX3        14:26:09
            16   F     OP   ARHDMN      FOXWELL     DFX3        14:28:02
            17   F     CL   ARHDMN      FOXWELL     DFX3        14:28:03

I think the 16 and 14 pertain to my sql delete.
