I am getting error messages when I try to delete from a table using
the values in the table itself. The intent is to delete all rows from
TableA where col_2 matches any of the col_1 values.
DELETE FROM TableA FROM TableA x INNER JOIN TableA y ON (x.col_1 =
y.col_2)
Error msg: The table 'TableA' is ambiguous.
Can this be done with SQL or should I use T-SQL with cursors here?

Hello,
I need help in replacing one string pattern with another.
Ex: I have a financial security expression like
log(T 3.25 6/24/2004)/sqrt(T 4.5 6/19/2002)
Here "T 3.25 6/24/2004" is a variable on which I need to perform log
and then divide the result with 3.980. While parsing such expressions,
I need to find all occurence of date values and replace "/" character
with "~" character. I need to do this only for date portion of the

Hi
I have a number of pages where it is valid for the user to enter HTML.
On these pages, I have turned off RequestValidation ("ValidateRequest =
false" in the page directive) so that the HttpRequestValidationException
that gets thrown if HTML is included in the Form, doesn't get thrown.
This is fine.
However, on some of those pages, there are fields where I don't want

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

I want to use the .replace() method with the regular expression /^ %VAR

regular expression with "":

The following DOES replace it though:

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...
