Java, the software developed by Sun Microsystems in the mid-1990s as a
universal operating system for Internet applications, gave NASA a low-cost
and easy-to-use option for running Spirit, the robotic rover that rolled
onto the planet's surface on Thursday in search of signs of water and life.

Hi,
I'm curious about the computational complexity of a query I have. The
query contains multiple nested self left joins, starting with a simple
select, then doing a self left join with the results, then doing a self
left join with those results, etc. What puzzles me is that the time
required for the query seems to grow exponentially as I add additional
left joins, which I didn't expect. I expected the inner select to
return about 25...

Greetings,
I like to write my inner joins as below,
but someone at work tells me its not as 'performant'
as using the 'inner join' statement.
Is this true ?
Is there a better way to write it ?
thanks

I have a SQL query I'm invoking via VB6 & ADO 2.8, that requires three
"Left Outer Joins" in order to return every transaction for a specific
set of criteria.
Using three "Left Outer Joins" slows the system down considerably.
I've tried creating a temp db, but I can't figure out how to execute
two select commands. (It throws the exception "The column prefix
'tempdb' does not match with a table name or alias name used in the
query.")

Hi All,
I wouldn't normally post this here, since this isn't *quite* the
appropriate place, but I think the quality of responses will be better.

I've used Access for many years. Several times, I've encountered a bug
which I refer to as the "Vanishing Joins" bug. When it happens, joins
vanish randomly from queries. More specifically, all joins vanish from
at least one (seemingly random) query.
I've always regarded the Vanishing Joins bug as a symptom of
corruption. When it happens, I usually give my users advice on how to
recover from corruption, and how to avoid it in the future....

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
