hello group,
i want to denormalize data in a temporary table for a second
business-system which cant read related datas
what i have:
table Partner: (Id_Partner, NamePartner, ...)
table PartnerProduct: (Id_PartnerProd uct, NamePartnerProd uct, ...)
table Partner2Partner Product: (Id, Id_Partner, Id_PartnerProdu ct)
Partner to PartnerProduct ist n:m relation (thats why i need
Partner2Partner Product)
and the temporary table
TempPartner: (Id_Partner, NamePartnerProd ucts)
whereas NamePartnerProd ucts should contains a comma separated list of
the PartnerProduct-Names
what i need:
a trigger or combination of trigger and SP which
operate like the following:
if on Partner2Partner Product is a Insert or Update made, then Delete
the row in TempPartner which has the Id of the Partner, and then
create a new row which contains all n:m joined PartnerProduct-Names in
it.
i hope the intention and problem are clear.
thanx for answers,
hans

The usual answer is that you should handle this in a client tool, rather
than in the database itself. There are ways to do it, but the only really
reliable way is a cursor (and if you need the comma-separated list in an
order, it's probably the only way), and cursors are slow: http://www.aspfaq.com/show.asp?id=2279

I have a database design question and wanted to see if folks could lend some

A book has a title has chapters.
A chapter has a title and has pages.
A page has a title has pictures.
A picture has a title.

I have an application where each user session opens and maintains a
long-lived connection to the postgresql backend database.
I need to keep a small amount of information (things like a unique
session identifier, the application - as opposed to database - username
and so on) that is local to each database session. It needs to be
visible from within plpgsql trigger functions and will be used
on a large fraction of updates.

For years I have been using VBA extensively for updating data to tables
after processing. By this I mean if I had to do some intensive processing
that resulted in data in temp tables, I would have VBA code that wrote the
results of that away to the db, either creating new records or updating
existing records, whichever was relevant. This may also include deleting
records.
Now I generally do this by opening a recordset on the source data...

I am cross-posting, as I'm not sure if this is an issue for the data layer
or the application layer. If this is unacceptable, can someone let me know

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.

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,...
