I have a table with 2 primary keys, one is a foreign key, the other is
produced by a sequence.
I want to SELECT query for one record that has a list of the
sequence-produced values for all records with a given foreign-key
value, essentially:
Create table table1 {
fk_id number,
seq_id number

Howdy,
I need to write an update query with multiple aggregate functions.
Here is an example:
UPDATE t
SET
t.a = ( select avg(f.q) from dbo.foo f where f.p = t.y ),
t.b = ( select sum(f.q) from dbo.foo f where f.p = t.y )
FROM dbo.test t

Hi.
Just as we have AVG(COLUMN_NAME) and MAX(COLUMN_NAME) how can I write
my own variation of a such a function. If I can appreciate how to do
this,
then I hopefully I can write a MEDIAN(COLUMN_NAME) type function or a
more general function like a 10% percentile function with syntax such
as
PERCENTILE(COLUMN_NAME,25).
Regards JC......

What do people think of adding some more aggregate functions. These are
the ones that MySQL has and PG doesn't:
- STD/STDDEV
- VARIANCE
- BIT_OR
- BIT_AND
- GROUP_CONCAT (for strings, added in MySQL 4.x)
Particularly, I find GROUP_CONCAT practical to quickly display 1-many

Hi!
I would like to make an editable continous form, where most
fields will be from table A and editable, except 1-3 fields are
a glimpse into table B and uneditable. Table A relate to table B
in one-to-many relation. I don't need to see all values in B
that relate to the particular record in A, just one value in
each field in B, preferably the last entered.
This is to ease a person that need to manually fix and encode

The current issue of "Oracle Magazine" has an article on creating
custom aggregate functions, which naturally got me thinking about how
to do this in DB2.
I found some articles on creating custom aggregate functions in DB2,

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
