In Oracle we can partition a table as follows. What is the equivalent in DB2?
CREATE TABLE sales_list
(salesman_id NUMBER(5),
salesman_name VARCHAR2(30),
sales_state VARCHAR2(20),
sales_amount NUMBER(10),
sales_date DATE)
PARTITION BY LIST(sales_state)

What is the impact of using a nullable column vs a not nullable column
for partitioning a Union ALL View? I have a Union ALL View with ten
underlying tables unioned based on different values for a column
partition_id in these tables. Now, if I define this column as NOT NULL,
I notice that the loading this view is almost twice fast as if I had
defined it NULLABLE. Can anyone explain? What exactly is DB2 doing in
each of the case when...

Hi,
this is just to verify: I checked the documentation and it seems that
SQL 2005 does not support hash partitioning on a number of columns. As
far as I can see only range partitioning is supported. Also, it seems
SQL 2005 only supports partitioning on a single column. Is that true or
did I miss something?
Kind regards

DB2 V8.2 (not Viper yet and no range partitioning!!)
I have created a table T1 (col1, col2) with col1 as the primary key.
When I try to create a partitioning key on col2, it gives me error that it
should have all primary keys included.
So, I created table T1 again with col2 as the partitioning key.
Now, I do not have col1 as the primary key.
When I try to create col1 as the primary key, I get the following error:
1 The primary key, each...

According to the original whitepaper on UDB range partitioning (http://
www-106.ibm.com/developerworks/db2/library/techarticle/0202zuzarte/
0202zuzarte.pdf), you can use a range as a criteria, either in the
UNION ALL view or in constraints. One restriction it lists, though, is
that the optimizer can't use a constraint that references a range
versus a discrete value for SQL containing host variables or parameter
markers. That was for V7 and...

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
