What is the datatype to be used
for Primary Key columns for most
optimised access given that
- There will be a single column primary key only
- The values will only be integers (but as
strings) at least 12 digits (characters) long
- all positions will be occupied (no leading 0's)
- Tables may have upto 1m+ rows

I have encountered a very strange bug. I am using a variable defined
as:
char ch;
If I assigned a character like 'Ö' (ascii 153) with a statement like:
ch = 'Ö';
It gets the value -103. It's as if char now is a signed datatype,

I have a production application that I am building some upgrades using
a second (empty) copy the database. A few of the upgrades included
changing the datatypes of a few fields from varchar to int(all the
values in this column are already numbers)
I am not trying to move the data from the production database into the
blank database using DTS and the fields that had their datatypes
changed are getting dropped by dts.
Is there anyway...

Hi Everyone,
We recently migrated our database server from DB2 6.1 FP11 windows to
8.2 FP 8 windows. The migration was successful, without showing any
signs of failure of any sort.
We have a jdbc application which interacts with the db2 8.2 (ESE
windows) database through a DB2 6.1 windows Client.

Hi All,
What are people's experience in timing Query Performance? I have
tried in vain, but get many unpredictable results, with execution
proceeding in the background and problems of timing precision.
I am trying to assess my applications performance difference using FK
using BYTE instead of LONG type. and not enforcing integrity at the
database level. (ie, Form level). This only becomes SIGNIFICANT when
the field is used highly in...

Excel Reading Method: ExecuteReade
I am currently running into a challenge reading excel data when datatype formats are different in the SAME column. It seems like datatype (in the OleDbDataReader schema) is set by the first data row and that causes a problem if any of the subsequent rows in that column holds a diffrent datatype

I have a class that I serialize/deserialize using xmlserializer.
There are a few properties with char datatype.

deserializing from xml if the properties having char datatypes have
numeric values(0-9) then everything worls fine. If I put any letter
e.g. A it starts throwing exception - "Input string is not in correct
format".
If I convert these properties to string, all...

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
Here is the code in...

Overview:
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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
