As you may have determined, I am relatively new to managing a sql server database and while I have found multiple...

I have recently been assigned to take over several MSSQL environments
and found some of the existing practice confusing. As most of my
previous experiences are on Oracle and Unix platform so would like your
inputs and comments.
1) TX log truncate:
In the existing environment, there are scheduled jobs to truncate
transaction log of each database in the server and shrink them back to
a desired size, say 1G. These jobs are all scheduled...

eg coalesce(col1, ' '). This column has 10,000 nulls in table A.
Select count(*) from table A where col1 is null=10,000
Using the load utlity, I load the data file as follows into table B which
has not null constraint on col1:

Recently I became interested, - Are the data, bulk loaded in the table with
LOAD utility, consume the same disk space as loaded with IMPORT utility? The
answer turned out to be NOT !
Here is a nutshell description of the test. The testing was done at
"DB2/LINUX 8.2.3".
Tables for tests:
F4106 has 5203 rows, 32 columns.
F42199 has 1399252 rows, 245 columns.

As part of my data warehouse nightly build, I truncate my tables in my
target database.
As example, I find it is much quicker to do a bulk API load of 13M
records and to do an update/insert of 100K rows. I also drop the
indexes before the builds and reindex after. Thats an aside.
What I am wondering is how is this impacting the statistics? Do I need
to update them?
Not well versed on statistics and any data is welcomed.
Thanks
Rob

I have a series of tables in which the data can be refreshed from a file.
Before refreshing the data, some of the tables are cleared using either TRUNCATE or DELETE.
If TRUNCATE is used, any index which is not PRIMARY or UNIQUE appears to be disabled and is not updated when new data is inserted into the table.
Performing an OPTIMIZE reactivates the index.
If DELETE is used instead of TRUNCATE, this problem does not occur.

Hello
I see there is now why to truncate a file (in C or C++)
and that I have to use platform-specific functions for
truncating files.
Anyone knows why ? I mean C/C++ evolved over many years now,
and still, people making _the_ standards never decided to
include such a function. Even in POSIX it was included only
in recent versions, mostly not fully supported yet.

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:

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,...
