Re: SQL duplicate a set of records within same file

Jeff -

As I just discovered, this method will require you to first determine within your program the name of the library containing the original file, and this library will need to be qualified in steps 2 and steps 4 for this technique to work, since once the temporary table is built in qtemp it will probably be first in your library list...

Also - you can use the statement: "Declare Global Temporary Table original like original" in step 1 to create the temporary table in qtemp, if you wish.

Regards,
Steve

Jeff - you can do it in a roundabout way:

1) Create table qtemp/temporary LIKE original

2) Select *from the original into the qtemp/temporary
where (.....using the appropriate record selection to select the
original batch #)

3) Update qtemp/temporary set (... the necessary field(s) in the temporary
table to change the batch number)

4) Insert into original
Select *from Temporary Table

Steve

Subject: SQL duplicate a set of records within same file

I don't know if this is possible, but I gotta ask.

I'm changing a formerly multimember DDS defined file into a single member
DDL defined table by adding fields that keep batches separate. On
occasion,
we have the need to duplicate a batch. We were able to do this before via
CPYF because we copied to a different member, so there was no need to
change
any field values.

What I essentially want to do is duplicate all records with KEY1, KEY2,
fld1, fld2, fld3, ... fldn to NEWKEY1, NEWKEY2, fld1, fld2, fld3, ... fldn
within the same file. Since I'm handling a _set_ of records, it seemed
logical to try SQL for this. I know it takes an INSERT, but the examples
I'm finding online seem to be specific to a particular database, or so it
seems. It would also be nice to not have to name all the columns . . .
