Hello,
I have 2 questions regarding InnoDB tables:
1. In the MySQL manual, it states that
"MySQL begins each client connection with autocommit mode enabled by
default. When autocommit is enabled, MySQL does a commit after each SQL
statement if that statement did not return an error."
Does using BEGIN override this behavior? In other words, with

Below is what I got by using MySQL's --log startup option. The original
Java(with JDBC driver) program that creates the queries at runtime was coded
by other people, and unfortunately, they are not available to answer any
question.
My question is: Do we need so many "SET autocommit=1" at all? Bu default,
MySQL always starts a new connection with autocommit
enabled.(?dev.mysql.com/doc/mysql/en/InnoDB_and_.., do we need to do "SET...

Hi,
Please see the history below...
Does AUTOCOMMIT as used here functionally replace VACUUM ANALYZE?
If I turn on AUTOCOMMIT is every transaction commited as it is
executed? If this is the case the query will take about twice as
long... I have actually tested this scenario.

With the advent of postgres v8, would it be possible to change the
default behaviour of psql from AUTOCOMMIT=ON to AUTOCOMMIT=OFF ?
Although this might break backward compatibility, it might be acceptable
on the basis that v8 is such a major release.
Also adding a new command line parameter to control the AUTOCOMMIT
setting for those users that will experience broken scripts executed
(especially using the -c command) might help ease...

Hi,
I am using nested resultsets to execute queries on two different
tables.
The code structure is:

Is there a standard way to get a descriptor object for an arbitrary
object attribute - independent of whether it uses the descriptor/
property protocol or not. I want some kind of handle/reference/
pointer to an attribute. I know I could make my own class to do this
(using the __dict__ of the object and the attribute name), but I would
like to use something standard (at least a protocol) if it exists.
All that is needed in the protocol...

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,...
