Hi there,
I have a dataset with two tables. They both have two columns which are
related (sort of a joined key). I know how to create one relation:
ds.Relations.Ad d("myrelation ",
ds.Tables["authors"].Columns["au_id"],
ds.Tables["titles"].Columns["au_id"]);
How can I create a relation to the column "issue_numb er" in the same
relation? Or how do I approach this?
Thank you
Chris

Depending on what you are trying to do, you can either create two separate
relations or you can use one of the DataRelation constructors that take
DataColumn arrays as parameters like this:
ds.Relations.Ad d("myrelation ", new DataColumn[] {
ds.Tables["Authors"].Columns["au_id"],
ds.Tables["Authors"].Columns["issue_numb er"] },
new DataColumn[] {
ds.Tables["Titles"].Columns["au_id"],
ds.Tables["Titles"].Columns["issue_numb er"] });

I have a table that I need to get the sum of four individual fields and then
rank them from highest to lowest total. After summing up the four fields
individually and ranking them, I have to place them in a single datagrid.
Example:
Table: contains fields for Revenue, Quantity, Credit Apps, Accounts by
rep (not my table!!!)

If I could create a SQL Statement to fill the datagrid, it would look

causes an error of 'Cannot find relation 0' when recreating the dataset from

Here is how you reproduce it.
Lets assume you have tables like this:

Hi all,
If I want to provide a typed dataset from a webservice and if that dataset
has relations that are nested (isNested=True), then the relations(keyrefs)
are not available in the XSD that is offered. If I set IsNested to false or
default, then it is included in the XSD.
Is this a bug or by design?

Hi,
I really hope someone can help me out here.
In relation to this thread ( http://www.thescripts.com/forum/thread349557.html ) I'm having a similar issue and getting nowhere fast!
In a nutshell I have a MDI Container which can load up several forms.
Upon loading of a form, I want this form to either access or load a dataset and populate controls that have been bound to various fields of the dataset.

I have a data structure composed with a dataset with multiple tables
connected through relationship. I'm using different table adapters of the
dataset for load table, but when i use the select method on master table
,data store in the other table are not filter.
I think that when there are relation with table a filter apply on table have
effect on the relate table drive by relation.
Any suggestions?

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
