Problem: getting SQL0181N for queries on nicknames to remote
Union-All-View.
Can't see what I'm doing wrong yet, maybe someone has seen this before.
Environment: UDB ESE 8.1 + FIXPAK 9A, on Solaris 8.1, with 64-bit
instances.
I have a NICKNAME called REMOTE_DW.T_MYT ABLE which points to a
"union-all-view".
Several other nicknames exist to regular-tables and regular views in
the remote database.
The "union-all-view" is in a database in another instance on the same
hostname,
(the remote-database).
If I perform "select count(*) on REMOTE_DW.T_MYT ABLE" then the result
is SQL0181N
(i.e. while connected as the instance-owner to the federated database
in which
there is a nickname for the union-all-view on the remote database).
The "union-all-view" has a partitioning-column of type DATE, if that's
important.
But if I perform that same query on the other database directly (i.e.
not using the nickname, using a direct connection to the remote
database),
then the query gives the correct count of rows.
Additionally, if I perform simple queries on nicknames that are NOT to
"union-all-view"
(i.e. they point to reguar tables, or regular views) then these queries
also work OK
on the federated database.
The symptom is specific to queries on nicknames for "union-all-views".
For both the local database, and the "remote" database, the
authorization-id is that of
the respective instance-owners. There is a "user-mapping" for the
local-instance-owner
to the remote-instance-owner. 6 3034

SQL0181N is a very common error and is documented in the
Reference/Messages/SQL portion of the Information Center. It simply
indicates that some portion of a date is out of range. For instance, if you
construct a date that has a month of 15 or a year that is outside of the
range 1 to 9999, you'll get an SQL0181N. Look at the expressions that you
are creating based on the values in your Date column and I fully expect that
you'll find a bad date expression causing your error.
I don't think the nickname or the fact that you are using UNION ALL is a
real factor in the problem, just red herrings tripping you up.

Hmmm, although I know well what the SQL0181N code means, it's just a
bit strange
that "select count(*) from <nickname_schem a>.<union-all-view>"
gives the SQL0181N, even when all target tables of the view are empty,
and
there's no dates specified on the query.

Sorry, I didn't read your question as carefully as I should have. I agree
that the full set of symptoms makes my original suggestion a bit improbable.
But I'm at a loss to suggest any good explanations for why you're seeing
this behaviour.
As for resolving the problem, I suggest that you look through the APAR lists
and see if there are any recent fixes involving SQL0181N; install the
appropriate fixpack if you find such an APAR. If you can't find any fixpack
that resolves the problem, call IBM Support for some help in tracking this
down.

I have this problem before. Just drop the nickname, and create a new
one. Try it.

I agree, support.

Thanks mike_li, just dropping and recreating the nickname was not
enough to fix it.
Instead, I studied the column check constraint on the target tables of
the union-all-view.
Could not see any problem, but as a trial I dropped and recreated the
check-constraints
on the partitioning column, for each union-all-view, and that worked
(did not even need
to disconnect from the federated database or remake nicknames).
There's a weirdness in there somewhere but I need to have a recreatable
scenario
before opening a PMR , so I'll work on that later. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi,
Is there any reason why a CREATE NICKNAME statement fails if the remote
object is an ALIAS ?
I actually have an ALIAS that is used to point to the correct table in the
remote DB, and would like the nickname to point to this alias, avoiding the
obligation to drop and recreate the nickname any time.
Thanks for your help,

Hi,
We have DB2 7 fixpak 14 on AIX 5.1. There are federated links
(nicknames) established for tables in Informix database.
One of the table was modified in Informix. The table has now got 3 new
columns. These columns are not seen in DB2 nickname definition. When we
run the queries, we do not see these columns in the result. When we
describe the nickname, these columns are not present.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
