I would have guessed on the first one.
My expericence say that one query is faster than many. *
* depends on the querystructure.

I need to extract data from this table to find the lowest prices of
each product as of today. The product will be listed/grouped by the
name only, discarding the product code - I use SUBSTRING(ProductName,
1, CHARINDEX('(', ProductName)-2).
I can get this result, but I had to use several views (totally
inefficient). I think this can be done in one efficient/fast query,
but I can't think of one.
In the case that one query is not...

Hi:
I must have missed something, but how is it possible that a join on
tables A and B is faster (a lot faster) than a query to one of the
tables with the same conditions?
The problem seems to be with the query plan, in the case os a query to
table_a only, the planner executes a "Seq Scan", in the case of a join,
an "Index Scan". table_a has about 4M records, so the difference is
quite noticeable.

We are migrating a customer from Version 7.1 FP3, to Version 8.2 (8.1 FP8).
For the most part, things are faster, but there is one query that is
much much slower, and it is a query that is used all the time.
select ATTR1,ATTR2,ATTR3,ATTR4 from physical.part_list
where S_PART_NUMBER like '%KJS%'
The widlcard before and after seems to be hosing it, but for this
particular piece of the application, this type of query is neccessary.

I always wonder which one of join or subquery should I be using to solve a particuar problem so that I get the correct result set in minimum time. It usually happens that I can write a query quickly using subqueries (I think I happen to think that way more easily than join way :)) but I see others making use of joins all the time. May be that they can think of a query more easily using joins. I am saying that because I don't usually see much of...

MDC *guarantees* clustering, whereas a table with a clustering index

That's not to say that a clustering index isn't still valuable
(especially for high cardinality columns that aren't a reasonable
candidate as an MDC dimension).

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,...
