I learned MySQL last year without putting it into action; that is why
I face trouble in formulating my queries. Were it a test, then you
would have passed it, because your queries did help me solve my problem.
I'll turn to MySQL doc after getting through this pressing project.
Thanks a lot Roger!

Here's one for pathological SQL programmers.
I've got a table of things called elements. They're components, sort of
like amino acids, which come together to form complex web pages -- as
nodes in trees which form parent-child relationships, sort of like
newsgroups. For example, the parent_id field points to another element.
Indent_level is there for denormalization purposes, to avoid costly
recursive issues in querying. The...

I find I often want to be able to do joins against views where the view are
aggregates on a column that has an index. Ie, something like
SELECT a.*, v.n
FROM a
JOIN (select a_id,count(*) as n group by a_id) as v USING (a_id)
where there's an index on b.a_id. assume there are other tables being joined
so I can't just move the aggregate to the outermost layer.

i know nothing about DB2, but i'm sure this must be possible.
i'm trying to get a client to create a view (which it turns out is called a
"Logical" in DB2). The query needs a LEFT OUTER JOIN, but he doesn't know
how to do that, or even if he can, and i don't have to time to learn DB2
from scratch right now.
The following SQL Query is a trimmed sample of the full View (i.e. Logical)
definition - and i would create it on an SQL based...

Hi all,
I have a table with analysis-results for various months. An item can -for a
particular month- have the result 'list1', 'list2' or 'list3' depending on
the result of the analysis.
Next, I want to get an insight in how the various items change over time.
For that, I compare the results of one month with the results of another
month. The form in which I want this is a cross-tab-query with one month as
a row-header and another...

Hello world:
Background:
Yesterday, January 21, Doug Steele was kind enough to help me out on a Left
Join problem. I was trying to return all stores and their Gross Adds for
December, 2004 (even though some of them had no Gross Adds for that month).
My query would only show the non-zero GA stores. Doug stated "It's because
of the Where clause. The stores which don't have any records for the period
in question are being eliminated...

Hi,
Solved a little mystery yesterday when I built a form that combined 2
tables with a 1:M relationship and relational integrity. All the
correct data was visible on the form but, if I tried to edit any of
the fields, the PC bleeped.
Seems it was due to the query the form was based on. Again, editing
any of the fields of the query caused the PC to bleep.

Hello all,
We are seeing strange behaviour for queries on a table we need to
convert data from. We try to find out whether table A(B_CONV_ID)
contains data that does not exists in table B(CONV_ID). We expect that
there is data missing in table B, thus finding a positive number of
records.
There are two tables, A and B.

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
