I have the following SELECT query, the results of which I would delete
from the table they're pulled from:
SELECT A.* FROM SalesOrderPartPrices A
WHERE EXISTS(
SELECT 'Exists' FROM SalesOrderPartPrices B
WHERE
(A.SalesOrderNo = B.SalesOrderNo) AND
(A.PartNo = B.PartNo) AND
(A.UnitPrice = B.UnitPrice) AND

Hi all,
I've been using scalar functions as a way to perform some complex data
transformation operations, and I've noticed that scalar functions
reaaaaalllllyyyy sloooowwwwww thiiiiiings dooooooown. I expect slow-down, of
course, and would even not be surprised at slow-downs up to a factor of, say
50:1, but I'm seeing slow-downs more like 1000:1 or 100000:1. I'm sure it
would actually be faster to actually export a table, use VB to...

when passing to it a parameter that is the result of another
user defined function.
My functions are defined like so:
drop function dbo.scalar_func

I want to know the differences between SQL Server 2000 stored
procedures and oracle stored procedures? Do they have different
syntax? The concept should be the same that the stored procedures
execute in the database server with better performance?
Please advise good references for Oracle stored procedures also.
thanks!!

I've worked with mdbs, and with SQL Server to a lesser extent, with
Access as a front end, on commercial-strength systems for quite a
while, starting with A97.
The last 8 months or so, I've been working on Access 2000/2002 with
pass through queries and linked tables to an Oracle 10g backend
(ODBC).
Access seems (still) to beat everything else hands down as a front
end/ prototyping tool for WIndows based systems. With my type of

I have a view that contains a complex query. A few of the columns
call a function that returns a specific output. I also use a function
to do a join as well.
For example:
SELECT l.ID, dbo.getStatus(l.ID) AS statusID
FROM tableName A
LEFT OUTER JOIN dbo.Status_LKP s ON dbo.getStatus(l.Leg_ID) =
s.statusID

In oracle, there is a performance improvement if scalar subqueries are
used instead of joins. Does this hold good for Db2 (8.2) too?

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...

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,...
