Coming from the C++ world I can not understand the reason why copy
constructors are not used in the .NET framework. A copy constructor creates
an object from a copy of another object of the same kind. It sounds simple
but evidently .NET has difficulty with this concept for some reason. I do
understand that .NET objects are created on the GC heap but that doesn't
mean that they couldn't be copied from another object of the same kind when...

I would like to remark on a problem described by Stephen Livesey
almost
3 years ago, about the slowdown he had experienced with an upload of
several
millions of rows.

This just seems like the most basic thing, but I can't find a simple
description of this process anywhere and in here, everone is talking about
going the other way :( I had .NET create an XML Schema file (xsd) for a table
in my database. I then create a DataSet that contains 1 row of data from that
same table. I want to use this DataSet along with the Schema file to create
an XML file that ACTUALLY CONTAINS THE DATA. Simple huh: DataSet +...

hi PGurus,
i searched the archives and read the docs, because this problem shouldn't be
new. But i really don't know what to search for.
i am populating a database (v7.4.1) with COPY. Some triggers in the db schema
fire on inserts and do some additional data manipulations, which i dont want
to take place by running COPY because my data don't need those additional
manipulation. Therefor and for performance reasons, i disable all...

Hi,
I am trying to import data using COPY, from a file containing thirty or
so COPY commands each with 0 or more rows of data. Reason, I have a
small data set I want to include into a database with an identical
schema, with existing data. I figured a good way to do this would be to
use pg_dump on the small dataset, trim out the table definitions and
constraints, and run the resulting file. (I also reordered the COPY
statements to...

Hi all,
I have a need to copy data from one database/schema to a different database schema. Yes, I can use export/import but that is not "elegant". Yes, I can try a redirected Restore from Backup but this method has the irritating requirement of pause, set tablespaces and continue, again much manual intervention.
What I am most interested in is this: The two databases are in the same instance/server. I want to be able to copy directly from...

Hi all
Probably an easy question for an oracle dba or even power user:
I would like to copy the data warehouse schema on my laptop for testing and
developing our application.
- Unfortunately I have a 80GB HD and the DWH contains a few 'tera'.
- Fortunately, I don't need the data (ok perhaps a few master data). I need
only the schema to avoid 'table not found' errors and so on.

Hi all
is there a simple command where I can just copy some data from one
database server to another?
For example, lets say i have two servers that have the same table
called "States"
If I have all the state names in server1 but want to copy the all the
data to Server2, how would I write a command for this?
INSERT INTO ..states

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
