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 have a log file in this format:
YYYYMMDD HHMMSS DATADATADATADATADATA RESULTCODE
and I want to be able to parse the log and gleen information about gaps in
time between transactions. For example, it would be nice to know that 8
times in the past 24 hours we had periods over 5 minutes where no
transactions were successful. In order to do that, I need to compare each
line against the next based on result code and time elapsed. To...

Hi,
I am seeking the help of volunteers to test some software that I've
developed which facilitates distributed two-phase commit transactions,
encompassing any resource manager (e.g. SQL/Server or Oracle) controlled by
Microsoft's Distributed Transaction Coordinator in a Windows2000
environment, with any resource manager under the control of DECdtm (e.g. Rdb
(or Oracle via the XA Veneer)) in a VMS environment.

Hello ppl,
Imagine some online system, based on PgSql. There are 'many' parts which
depends on each other. I will give small example, but instead of simple
table imagine changing tenths various tables (editing). So, 'change table A'
can be work for hours.
There are tables tableA and tableB. Changes are made by thin client. If
you change tableA, you have to also change tableB to 'finish' operation.
Between starting changing tableA...

Hello, I'm expiriencing something weird, once in a while I have duplicated
transactions because it looks like a stored procedure is being executed
twice from .NET. When this happens I get 2 record transactions which is
incorrect, but doesn't happen all the time. Here is the example of how I'm
invocating the sp:
SQL = "sp_w_PickQty '" & UCase(vIncoming) & "','" & genparams(0)
& "'"

Hello,
I am learning .NET 2.0 (ASP.NET, ADO.NET). I would like to ask experienced
programmers when to use System.Transactions. One programmer told me that he
never used System.Transactions, he only uses database transaction
(SqlTransaction) and recommended me this method but he did not explained
why. I have read a few pages about both transaction types in MSDN but I have
little experience I don't know what are practical usages of...

I have some requirement for an automated payment system. The system has
four machines setup as follows:
1- Two machines have a clustered database.
2- Two machines have a .net business logic component that will handle
payment transactions with certain external component (Payment Gateway)
My query is regarding transaction handling inside the business logic
component. Because this component is running on two machines and these

I used the classes (SqlCommand, SqlConnection) of part of System.Data
namespace.
I got an error which mentioned "Could not load file or assembly assembly
'System.Transactions, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=B77A5C561934E089 or noe of its dependencies.
What should I do to fix this issue?
Strange enough, this application works fine other boxes except one box

I have a small database that I have been testing.
I get an error about a transaction deadlock.
The code is in stored procedures and I added transactions to the sp's
but the error happened again.
I wrapped the whole sp in just one transaction and I don't have any
index on the tables.
When I test just by running a program that sends 3 calls at a time it
will get a deadlocked transaction as I send 6 or 9 at a time.

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,...
