Hello,
I have a table which has a few million records. It has an IDENTITY
column that serves as the primary key. In a part of our application
here, a previous record may need to be copied as a new row. Within a
stored procedure exists SQL like:
INSERT INTO .. (col1, col2, col3, ...)
SELECT @var1, col2, col3, ...
FROM My_Table

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.

Greetings,
In Google I am finding what the deffinition of a table spool operator is
but not what it is doing to performance. The execution plan shows the
output of a clustered Index scan (54 records) going into the Table Spool
operator and having a output of 218,000 records out. Where do the 218,000
records come from??

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...

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,...
