Beside its an opensource and supported by community, what's the fundamental
differences between PostgreSQL and those high-price commercial database (and
some are bloated such as Oracle) from software giant such as Microsoft SQL
Server, Oracle, and Sybase?
Is PostgreSQL reliable enough to be used for high-end commercial
application? Thanks

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)

I have just started working with DB2 Data Partition Feature.. Given a
table
name, how can I find out the partitioning key of that table? Is there a
SYSIBM.*
table that I can look at?
Thanks,
Jorge

hi,
does cost of SQL include broadcasting etc. as additional cost ?
cost of SQL doing join on partitioning key is less than cost of same
SQL doing join on cluster index which has column other than
partitioning key

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:

Hi, Happy New Year.
I am trying to insert a query to a partitioned view but the error is :

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
