Hi, I have some problem in using SQL3 recursive queries on DB2
database system (8.1 and 8.2 UDB).
I need to compute the transitive closure of a (possibly) ciclic graph
using SQL3 on DB2.
I MUST use pure SQL3 and I cannot use cursors, indexes and the like.
The graph is represented by a set of arcs with the table "arc"
having two attributes "a1" and "a2" for source and target nodes resp.
The SQL3 query I'm using is the following:

I am hoping someone can help me. I am making a Access 97 app for a
person and have run up against a problem to do with MS Graph. There is
a table that has a number of data elements and a date field and
entries are entered each month.
A graph is required that has three of the data elements represented
basically on the y axis and time as months along the x axis. So for
each month there is a group of three columns representing the data...

Hi .. I have an issue I have been beating my head against
the wall on for some time. I am trying to use late
binding for MS graph so that my end users don't have to
worry about having the right version of the MS Graph type
library. Up until now I have been walking them through
the process of setting the references to include their
version of MS Graph library.
My problem is that I can not seem to get the syntax
correct .. or perhaps...

Hello.
I have a MS Access front end/PostgreSQL back-end combination.
There is a report with nested graph (linked master/child fields).
I used saved pass-through queries for both Record Source of the report and
Row Source of the nested graph. It works, but, when I have a lot of data,
the report has several hundreds pages and opening of the report is extremely
slow (cca 20 minutes). It's because for every page it must requery the Row...

I'm working on an image segmentation algorithm. An essential part of the
algorithm is a graph to keep track of the connectivity between regions.
At the moment I have a working implementation, but it's not flexible
enough anymore and I need something more advanced. I already have a data
structure in mind, but I don't know how to implement that nicely in C++.

Hello,
I am trying to create a running subtotal in a query and then graph the
running subtotal for each city group. The data looks like this in the
table (for illustration):
My City My Date Cumulative Sum Daily Sum
DC 03-Apr-07 6 6
DC 04-Apr-07 20 14
DC 05-Apr-07 0 0
DC 06-Apr-07 24 4

Hello Everyone, I am almost completed with this database, the only thing left is to graph the results of a query. I built a parameter query that gives me totals for a date range that I enter. This works great. I created a column called "Month", and I am entering the month and year corresponding to the "Date" field. ie. (03/15/06 for the date) (Mar-06) for Month. If I do the Query to show me 1/1/2006 to 12/31/2006, I get the results with Date...

Hello dear forum.
Anyone who has an experience with ms-graphs, maybe he can enlighten me on this one:
I'm using a cross-tab query with Totals for this graph. When there are less then 10 results (without the Total) the last (Total) column doesn't appear hatched. When there are more than 10 results it does appear hatched.
Is there anyway to configure it?
Thanks much.

I want to create a graph (automatically in a report) which compares
the current year's values to the previous years by plotting two lines
on one chart.
I have one table which has the fields: Date and DeckDefects (which
is a number)
I would like the X axis to show months and the Y axis to show # of

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. 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....
Now, this would greatly impact the work of software developers. The idea...
