In my MYISAM table I have an index (Index_A) on 2 fields (Field_A,
Field_B). There are millions of rows in the table. The cardinality of
Index_A is 53. I think a query to count the number of rows that match
a pair of values for Field_A and Field_B should execute blindingly fast
(in the index count the number of leaf nodes for the B-Tree node
representing the indexed pair of values).
My query looks like:
SELECT count(*) FROM `table_A`...

I've got the following code
testlabel.Text = allquestions.Select().Count.ToString();
GridView1.DataSource = allquestions.Select();
GridView1.DataBind();
testlabel.Text = GridView1.Rows.Count.ToString();
allquestions.Select().Count.ToString(); is reporting the correct
value, but GridView1.Rows.Count.ToString(); is reporting the incorrect
value (it is reporting 0)

I see tutorials all over the web with pagination and MySQl but not much out there (that is updated using PHP 5 without global variables) on doing this using ODBC connection with MSSQL.
This is what I found online but I am confused.
<?php
//connecting to the database using ODBC
$db=odbc_connect($dsn,$user,$pass)or die("Error: Can't Connect to Database");
// assigns a value how many rows we will get from each page

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

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.
