Hello there,
I am at my wit's end ! I have used the following script succesfully to
upload an image to my web space. But what I really want to be able to do is
to update an existing record in a table in MySQL with the path & filename to
the image.
I have successfully uploaded and performed an update query on the database,
but the problem I have is I cannot retain the primary key field in a

Hi,
I have dynamically created a PDF document in memory as a FileOutputStream
Now I have to get it into a DB2 table, storing it as a BLOB. The table has a
document id,
document name, some date fields and this BLOB column that stores PDF Files.
Until now, the PDF files were read off of a disk drive. The code used was:
byte fileAsBytes = (byte) adminDocEvent.getFile();
which returns an object.

Customer wanted us to figure out why their database was growing at an
astronomical rate.
We broke down the various fields making up a table, and we found that the
..LB file was using about 1k per row, where the average length of the two
combined CLOB fields in the table was 12 bytes (4 bytes standard deviation).
So i hex edited the .lb file and found the problem, each clob value is
taking 0x400 bytes i.e. 1024 bytes.

Anyone hashing or storing URLs for later lookup? I was curious for the best
practices on storing such a wide column that needs indexing and if there
were alternatives. We have a table an are anticipating millions of rows and
want to look up the content through the URL, due to SQL server we have a 900
bytes restriction on the index. Would hashing be the way to go (and look up
via the hash) OR just limit the URL length to 450 nvarchar (900...

I have the following code. I upload an XML file using the FileUpload object,
store the stream in a session so the user gets the chance to confirm some

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,...
