Oh no! It's me and transactions again :)
I'm not really sure whether this is a limitation of psycopg or
postgresql. When I use multiple cursors in a transaction, the records
inserted at the start of the transaction aren't visible to those later
on in that transaction (using a different cursor).
Attached is a simplified example (the except's are a bit blunt, I know)
of what I'm trying to do. In reality, the different cursors are...

Dear All,
We are using Oracle 9i databse and Oracle JDBC Driver version -
9.0.2.0.0(oracle.jdbc.driver.OracleDriver) with JDBC 2.0.
1) The following block of statement returns 0 when executed. Is there
a way to determine whether the session has actually been altered?

Does anybody have samples of how to use JDBC calls to work with a
cursor on Oracle 8i? Can it even be done?
I'd like to be able to do something like:
String sql = "DECLARE CURSOR my_cursor FOR SELECT name,id FROM
name_tbl";
statement.execute(sql); (executeQuery? executeUpdate?)
....
while(...)

Hello,
I am doing some multithreading in an MDI app, and I can't seem to get the
cursor to stay as an Hourglass. I call:
Cursor.Current = cursors.wait
at the beginning of my routing, and set it back to cursors.default when the
thread ends (using a callback)

Does Me.Cursor.Current=Cursors.WaitCursor
set the current property of Me.Cursor to Cursors.WaitCursor
And Me.Cursor.Current=Cursors.Default set the Me.Current
property to something (default) stored in Me.Cursor.
Or is Cursors.Default some process wide cursor shape?
What is a correct statement?

Why must a cursor be defined in an open transaction? Obviously there's
a good reason, but I can't figure it out. On a high level, what would
be involved in allowing a cursor to outlive the transaction that
created it?
Cursors seem as if they have some nice performance benefits (esp. if
you're not using all rows found), but their usefulness drops
considerably since you must leave a transaction open.

Hi everyone-
I'm using the Microsoft JDBC driver for SQL Server 2000 and I'm trying
to avoid using server cursors.
Is there a way to guarantee that every query will not create a
server-side ResultSet with a cursor? In other words, I want every
ResultSet to be loaded into the client's (the web server's) memory.
Does setting the "selectMethod" connection property guarantee this?

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,...
