I'm sure this is a concept that's been explored here. I have a table
(fairly simple, just two columns, one of which is a 32-digit checksum)
with several million rows (currently, about 7 million). About a million
times a day we do
select * from my_table where md5 = ?
to verify presence or absence of the row, and base further processing on
that information.

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)

Is it possible to generate a 20 byte integer from a GUID that is "unique
enough" ( just like a GUID is not truly unique , but is "unique enough" ).
We identify transactions with GUIDs , but a partner web service has a 20
byte limit on transaction ID passed.

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:

Counties, partitioned by state.
Can I use TWO levels of partitioning?

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

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
