Hi All,
Can multiple updates on one table using single
query generate deadlock ?
For example, at the same time, there are 2 users
run 2 queries as follows :
User1 runs :
update tab1 set tab1.v = tab1.v + 1
from tab1 inner join tab2 on tab1.no = tab2.no

Here's a really weird one for any SQL Server gurus out there...
We have observed (SQL Server 2000) scenarios where a stored procedure
which
(a) begins a transaction
(b) inserts some rows into a table
(c) re-queries another table using a subquery which references the
inserted table (correlated or not)

I`m exporting data from many Lotus Notes databases to a DB2 database
using LotusScript. The LotusScript agents commit after EACH
update/insert. Nevertheless, I keep getting transaction rollbacks on
deadlock or timeout. When I get a snapshot for locks, I see that one
of the export agents is getting a table lock rather than a row lock.
I`m guessing this is what causes the time out. Questions: how do I
determine whether it`s a deadlock or a...

Hi There,
I'm getting a deadlock when I have two clients running the following statement.
DELETE FROM intermediate.file_os_details WHERE file_uid = ? AND obj_uid
There is a compound index on file_uid / obj_uid.
The isolation level is UR and I have set DB2_RR_TO_RS=YES.
Any thoughts why I'm getting the deadlock ?

Hi,
The bigger my C# web-application gets, the more places I need to put in the
tedious retrying block of code to make sure operations that can run into
database deadlocks are re-run (retried) 3-4 times and give up if after that
it's still in deadlock. I'm very sure that many experienced people out
there already deal with this issue somehow. Is there an alternative to it?
Thanks for your comments and suggestions.

I sometimes get the following error from an update statement in a
stored procedure:
Transaction (Process ID 62) was deadlocked on thread | communication
buffer resources with another process and has been chosen as the

The isolation level is READ UNCOMMITTED and there are no explicit
transactions in the stored procedure. The update statement is as

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...

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,...
