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

Hello,
I have a stored procedure and the return data type is number(16) as you
can see. but I get it back in the code as a var_numeric and then the
precision depends on the value of the returndata. So 0 fits into a short
so I have to convert to a short, although I say that my stored procedure
has to return a NUMBER(16), thus int. Can anyone tell me how I can
determine my return datatype beforehand?

Hi folks,
I've got a program which has a function which uses templates to accept
parameters of any type.
Works well, but there's one certain datatype which I want to special case
and do an extra thing to. The datatype is a class I made.
Is there anyway for me to test a parameters datatype in a template using
function?

Hi All,
I am using Microsoft.ApplicationBlocks.Cache.CacheManager to persist a
System.Data.Dataset object. This Dataset object has a DataTable that is
created from an existing DataTable using the Clone() method. Before I
add the new DataTable to the DataSet, I change the DataType of a
DataColumn from System.String to System.Int64. I then add data to the
new table and then add it to the DataSet. Then DataSet is then added to
the Cache....

In VB, to know the field type of a column stored in a recordset the command I
use is
If rsQuery.Fields(k).Type = adCurrency Then
How will I achieve the same in ASP.net. I could not find a currency data
type in asp.net and the type is idenfied as decimal.
I have two fields defined in Sql-Server, one is money and other is decimal.
In asp.net both are identified as decimal.

I have a class called "Prop". I want that class to have a property
called "DataType" where the user can select and store a datatype. How
can I store a DataType value in a class property.
how the code would work in my mind:

TempProp.DataType = String

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...

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,...
