I have a deadlock that's happening on one oracle instance but cannot
be reproduced on any other. It is always caused by the same SQL
statement colliding with itself and only happens under very high load.
The statement is

the schema for the userlogins table is

I am getting quite a few deadlock errors where both sessions are
trying to execute sp_execsql according to the the trace information in
the error log (see below). The database is being asscessed by an
application written in .NET, as well as a few people using Query
Analyzer. This seems to be happening relative randomly - can't pin it
to any specific circumstances. Any thoughts would be appreciated.

I want to set an alert for a specific table whenever an event has
caused a deadlock to occur on the table.
I understand how to set up an alert. But I don't know which error
number to use for the New Alert error number property for a deadlock.
Or how to specify a deadlock on a specific table.
Thanks,

I was hoping someone could confirm my understanding of how InnoDB
handles deadlocks (error 1213) and timeouts (error 1206). The way I
understand it, with AUTOCOMMIT=0, if I issue 3 SQL statements
(updates), A, B, and C (in that order), and get one of the errors above
while issuing statement C, InnoDB will have rolled back statements A
and B. To recover from this error condition, I need to re-issue
statements A and B, followed by C. ...

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.

Hi
First a simple question ...
I have a table "access_log" that has foreign keys "app_id" and
"app_user_id" that reference the "application_type" and "app_user"
tables. When I insert into "access_log", the referential integrity
triggers generate these queries:
SELECT 1 FROM ONLY "public"."application_type" x

Hi ,
I am trying to acquire a lock on a table A in exclusive mode, and this
statement gives an error indicating a deadlock or timeout
has been detected. The lock timeout value is set to 0 which I understand
is to wait for however long it takes to acquire a lock.
Also there are other processes that have acquired row level exclusive
locks on the table A when this error happened.Is DB2
throwing this error as a pre-emptive measure.

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:
