After some thought on what I need in a Python ORM (multiple primary
keys, complex joins, case statements etc.), and after having built
these libraries for other un-named languages, I decided to start at the
bottom. What seems to plague many ORM systems is the syntactic
confusion and string-manipulation required to build the SQL Statements.
If you want to do a Left Outer Join, support nested functions, and a
nested conditional clause, you'd...

I have designed a form that has 5 different list boxes where the
selections within each are used as criteria in building a dynamic
query. Some boxes are set for multiple selections but these list boxes
do not necessarily need to have a selection made to be used in the
dynamic query.
In essence the form can have selections made in all or none of its list
boxes to form the dynamic query
I am looking to get some feedback in reference to...

Hello,
played a little with orcas and went into a problem by building dynamic
queries. I want to build a dynamic where clause but only with parameters that
are not empty =(TextBox.Text != "").
Doing this by building a string is very simple, but how to do it with LINQ?
string sql = "";
if (TextBox1.Text != "")
sql += "Columns_1='"+TextBox1.Text+"'";
if (TextBox2.Text != "")

Hello all,
I am developing an application in VB 2008 that works with a SQL2005 DB to store and manipulate employee data. In one section of the app I want to be able to show a treeview of the hierarchy as a whole showing a nested hierarchy of who reports to who such that when it is first loaded, all you will see is the top guy in the company with a plus next to his name. Opening that will reveal his first level reports and opening those will...

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...

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...
