Here's a really weird one for any SQL Server gurus out there...
We have observed (SQL Server 2000) scenarios where a stored procedure
which
(a) begins a transaction
(b) inserts some rows into a table
(c) re-queries another table using a subquery which references the
inserted table (correlated or not)

Postgresql 7.4b2 (approximately, compiled out of CVS)
When I have a subquery that has a complex subquery as one of the result
columns, and then that result column is used multiple times in the parent
query, the subquery is inlined for each one. This means multiple redundant
executions of the subquery.
I recall there was a way to defeat this optimization involving introducing an
extra subquery layer somewhere. But I'm failing to be able...

Hi!
Does anyone here know of a way to goad DB2 into converting a correlated
subquery to a non-correlated one? Does DB2 ever do such a conversion?
We have a query of the form
SELECT .. FROM A
WHERE EXISTS (SELECT 'X' FROM B, C
WHERE B.COL1 = A.COL1
AND B.COL2 = A.COL2

Don't know if this is the proper newsgroup to post to. Sorry if not.
Can't figure this one out. Using Access 2003. I have 2 tables, IMast
(table of part info) and THist (part transaction history).
I need to select all parts that have a product code = "CAST" and list
the last 10 history transaction if they are within 90 days of the run
date.
From the IMast table I need the columns: part, descr, pcode. From the

Hello!
Here is the statement in question:
--STATEMENT A
SELECT * FROM dbo.myTable WHERE colX in (SELECT colX FROM
dbo.sourceTable)
The problem with Statement A is that 'colX' does not exist in
'dbo.sourceTable'. It does, however, certainly exist in 'dbo.myTable'.
Breaking the statement down, we have:

Hi all--
Does anyone have any insight as to how I might create a search form
that allows a user to select criteria based on any related table in
the whole database. The search form I have now only allows me to
filter based on variables in a single table. I would like to have a
search form where I can select multiple variables (from various linked
tables) to filter by, and return results based on this multi-table
filter.

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

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
