What causes the query optimizer to choose a table spool\lazy spool
action in the execution plan? The explanation of "optimize rewinds"
makes little sense because my query never comes back to that table.
I'm going to have to change the query but it would be helpful if I
knew what I should be trying to avoid.

Does anyone know of a way to execute sql code from a dynamically built
text field?
Before beginning, let me state that I know this db architecture is
built solely for frustration and I hope to make it better soon.
Unfortunately, there is never a non-crucial time in which we can do an
upgrade, so we are stuck for now.
Point 1:
There are multiple tables: students, courses, cross-reference

Hello.
I am administering a SQL Server (Enterprise Edition on Windows 2003)
from some month and can't understand what is going on in the latest
week (when the db grow a lot).
The DB is around 250G, and has one table with 1 billion rows. It is
performing in a decent way, but can't understand why a particolar table
has strong performance problem.

Hello,
I am currently working on a monthly load process with a datamart. I
originally designed the tables in a normalized fashion with the idea
that I would denormalize as needed once I got an idea of what the
performance was like. There were some performance problems, so the
decision was made to denormalize. Now the users are happy with the
query performance, but loading the tables is much more difficult.

Our application is having an issue where a query in a stored procedure periodically gets a bad plan with a Lazy Spool Operator that changes the query execution time from 5ms to 900ms and kills our CPU. We are running x64 SQL 2005 SP2 on Windows 2003 SP2.
We thought it might be parameter sniffing that was causing the bad plan, so we re-wrote the query to disable parameter sniffing. Unfortunately, that made the problem worse as we always...

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...
