Re: Archive Tables View? or better option.

You can always write a CONTINUE HANDLER for an SQL error/exception if you
don't find any of the tables needed, and if you write it in an embedded
SQLRPGLE program you simply ignore the error and you will get what is there.

I have a series of tables that are created to archive tables, the max
number of archive tables is 999. These tables exist in a library called
ARCHIVE. When a new table needs to be archived the process is to
increment
the table number by one and drop off 999. The new table is number 000.
The list would look like this:
ETBL000
ETBL001
ETBL002
.
.
.
ETBL997
ETBL998
ETBL999

I have a program that reads each of the tables searching for a string.
The
overhead of open/close is making it slower than the users like.

I am thinking about creating a view like this.
create or replace view archive.v@etbl_0
as (
select '000' as TblNumber, e.* from archive.etbl000 e
Union all
select '001' as TblNumber, e.* from archive.etbl001 e
Union all
select '002' as TblNumber, e.* from archive.etbl002 e
.
.
.
Union all
select '997' as TblNumber, e.* from archive.etbl997 e
Union all
select '998' as TblNumber, e.* from archive.etbl998 e
Union all
select '999' as TblNumber, e.* from archive.etbl997 e
)
RCDFMT v@etbl_0R
;
Downside to this is that writing the view will be a pain. but I only have
to do it once.
Another gotcha is that it is possible that a table may not exist. For
example etbl002 may have gotten deleted. This should make the SQL
statement fail.

Anyone have any better ideas?
