I have a question about oracle commit and transactions. Following scenario:
Process A performs a single sql-INSERT into a table and commits the
transaction. Then he informs process B (ipc) to read the new date. So
process B starts "select ..." but does not get the previously inserted
row. The timespan between commit and select is very short.
(NOTE: two different sessions are used)
Questions:
1.) Does commit when returning from call...

I wrote a script that uses the sp_refreshviews. The script will be part
of a larger one that is automatically run in multiple databases where
different views exist.
Question:
My understanding of views is that by simply stating 'select * from
myviewname where 0=1' that the view is recompiled. If so, what
advantages are there in using sp_refreshviews?
I couldn't handle the errors that sp_refreshview produced (I am sure

Hi All,
how can I improve the query performance in the following situation:
I have a big (4.5+ million rows) table. One query takes approx. 9 sec to
finish resulting ~10000 rows. But if I run simultaneously 4 similar queries
it takes nearly 5 minutes instead of 4 times 9 seconds or something near of
that.
here is a sample query:
select mertido, fomeazon, ertektipus, mertertek from t_me30 where fomeazon
in (select distinct fomeazon...

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:

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,...
