Mr. Kyte's article doesn't use cursors, while Mr. Feuerstein's
book examples do. my recollection of conventional wisdom is
to avoid using cursors.
is this difference merely a question of style, or is one
approach right and the other wrong?

I am trying to write a cursor to update certain rows in a particular
order as follows: (I need the cursor version, not SQL, as the update
logic depends on the order of rows and some other conditions. I
removed the Order-By clause from the statement to simplify it; it
gives the same error message with or without it.)
DECLARE prod_cursor CURSOR
FORWARD_ONLY
KEYSET
FOR SELECT 1 FROM all_products WHERE p_qty = 0 FOR UPDATE

Hello All!
We have a cursor in an application which fetches some data out of a DB2-DB.
Normally it all works kind of well.
We inserted a routine at certain places in order to do some
perfomance-monitoring .
Now we got the problem, that the cursor closes at some point although not
all the data has been fetched and then next fetch of the application causes
an error.
Is there a way to force the cursor to stay open?

Hi,
I am trying to declare and cursor and thn load from that cursor into
another table. Since I have almost 4 million records, I cant do it
without the cursor which reduces the time by almost 1/10th.
I tried to create a sql statement for "load from cursor cur insert into
table name" using java stored procedure, but this isnt recognised by
sql since load isnt a sql keyword. So whats the solution to this. I
have to do it programatically...

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,...
