hi,
I have a password field that I need to store in a db2 database. I created a blob field in my table, and I am trying to update it with the following java
dal.getPrepared().setBytes(15, pwBytes);
The code executes without errors, but when I look at the field, it has this in in
COM.ibm.db2.jdbc.app.DB2BLob@3a3d1183
I am trying to figure out how to convert a bytes field into a blob, but I am coming up dry.

Hello!
I have Oracle 10g using AL32UTF8 as internal charset.
I have a documents table where uploaded files (I'm using modplsql
web-gateway (release 8i)) are stored in a blob-column. I upload a
CSV-File to this table which is in ISO 8859-1 Charset.
I now need to convert this binary data (which is in fact all
character-data) into utf-8.

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,...
