Primary Key error wrong number of qualifiers

[sachin]

Hi,
I am facing some strange issue in DB2 UDB 9.5.1

I have created a database on DPF implemented environment and I tried
to execute following commands

Db2 create table test ( name char(10) not null, acno integer not
null );
Completed successfuly

Db2 alter table test add constraint PK_test primary key ( acno );
DB21034E The command was processed as an SQL statement because it was
not a
valid Command Line Processor command. During SQL processing it
returned:
SQL0108N The name "PK_TEST" has the wrong number of qualifiers.
SQLSTATE=42601

But if I create primary key on first column ( Db2 alter table test add
constraint PK_test primary key ( name ))
it works fine. I am not sure whether it is related to DPF or Db2
version.

Please help.

Regards
Sachin Shinde

Is this the exact statement or have you sanitized it?
This error is raised if you give a "one part name" a "dot".
Your _example_ looks sound.

Hi
It's complete error...I am also facing another related issue also... i
think it's related to this only...
i am not able to create 2 unique indexes on this. Facing following
error

DB21034E The command was processed as an SQL statement because it was
not a
valid Command Line Processor command. During SQL processing it
returned:
SQL0270N Function not supported (Reason code = "1"). SQLSTATE=42997

i could create the same on non DPF database which is on windows and
DPF database is on linux.

This is DPF.

I suggest you read the documentation about the requirements for
partitioning keys and their relationship to unique indexes (i.e. primary
key or other unique keys).

While you're at it, read up on how DB2 selects a partitioning key if you
don't specify one explicitly.


In short: Unique indexes must include all column(s) used as the
partitioning key. The partitioning key may be a subset of the columns
in the unique index.

Hi

Unique index key on partitioned table should include columns used for
partitioning. But in my above example i am not creating partitioned
table also. It's normal table only. only implementation done is
database partitioning on instance level.

It sounds like you don't understand what database partitioning is. I
recommend you read the manuals or other articles so you understand
what exactly DPF is. Here is an introductory article:

http://www.ibm.com/developerworks/db2/library/techarticle/dm-0405wilkins/index.html

Note, DPF is not the same thing as range partitioned tables.

Hi,

Thanks for reply.

I got the problem. I never considered that DB2 distributing every row
in the table by default without mentioning the distribute by clause.
If we don't mention the same while creating the table, it does select
by it's own which we may not use as subset in primary key OR unique
index.
In DPF environment, wee should always use distribute by clause to
avoid this kind of issues.

Thanks once again.
