Hi,
Why is there no support for explicit transactions in the DB API? I mean
like transaction() to start the trans and commit() and rollback() would end
the trans or something.
The reason why I ask is because I wrote a daemon that interacts with a
Postgres DB. The value of CURRENT_TIMESTAMP according to Postgres is NOT
the actual walltime, but the walltime when the current transaction started.
This gets weird when using the Python DB...

I am having huge problems migrating large db’s from one server to
another. I use phpmyadmin to dump the data into a file, and then
migrate it to my production server. Then I try to use this:
mysql dbname < filename
but if the tables are too large, it simply does not work.
So I tried the following two work-arounds, which work but are tedious.
Is there a nicer way to do it:
Solution A: Create a dump file with subset of all the...

Scenario description -
We have two Oracle DB's A & B. Both DB's have a table test1 (customerid varchar2(50, val number). The idea is that for every customer id, the counter (stored in val) increases.
Whenever we send a file to the customer, we tag/identify it with a counter value. This is for verification on the customer side that they have received all files by checking for a break in the counter.
We have many customers in the table, each...

We have an app that queries 5 tables into a dataset. Now, lets say 1 of
those tables is about to change due to user input on a webpage. Right now,
we are manually updating the db with an update command (execute non-query)
in a web service. But now, we're not sure how to now update the table in
the ds. My thinking is requery that 1 table, grab my dataset from the
session & do sda.Fill(myDS, "tblEmployee") which will keep my existing ds,...

I'm testing the waters of n-tier development and I ran into a scenario that
I'm not sure what the best solution would be. I have a Company object which
contains a collection of contacts retrieved from a database.
In the presentation layer, the user will be able to add/delete/modify this
collection in which case it needs to be synced with the database.
The question is basically how best to do this? Aside from overriding the
add/remove...

I have a form where the user may see a matrix of data in a grid (populated
via a dataset). If the user wishes to add a new row of data, they click a
button and a new form opens where the user may enter data into each
textbox, then click the add button when finished. At this point a stored
procedure is run which inserts the new row into the database (not the
dataset), given that the row is not a duplicate and the contents of each
text...

I have to synchronize 2 databases hourly but am having difficulty maintaining foreign key relations. These tables use auto-increment columns as primary keys, with child records in other tables related with foreign keys. I can't change the way the local software uses primary or foreign keys as it is hardcoded in the local app. (microsoft retail management system)..(however the web-remote app is easily customized). I am using CDB synchronizer to...

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...
