I have created a dataset with two tables and an insert command, I need to be
able to retreive the Key Identity after inserting into table "A" for use in
table "B".
Should I use ExecuteScalar() or is there a better solution?
Thanks, Justin.

Hi I need to update a field (fldX) in one DataTable (dt1) where there is a
match on fldA in another DataTable (dt2).
Is the only way to do this by itterating through the DataRows of dt1,
serching dt2 for a matching fldA and if found do the update and then move on
to the next row?
Thanks Greg

Hello,
I have 2 datasets I am trying to update. The parent table seems to
update fine but when I go update the chiled table I get an error message
that says I need a related record in the parent table. However I put some
code in to display the key field of each parent table record (parent
dataset) and the value I am trying to put into the child table is there.

Hello,
I have 2 tables with a relationship set up in the dataset with vb

record to have the new parent ID. However when I do the update the changed
parentid in the child table fails to change. No error is given its just that
the change is not written to the Database.
When I step through the records for the child table the one I would expect
to be changed has a row...

Itemlookup table
Field names : index_id (primary key), itemno, description.
It has a child table, which is ItemPriceHistory table
The relationship to the child table is one (parent table)-to-many
(child table). - It is possible to have no child record for some rows
in the parent table.
ItemPriceHistory table
Field names: index_id (primary key), itemlookupID (foreign key of the

I have a parent record with a child record.
The parent record contains structures and the child records contains
visits to those structures.
Each table has a field named "Complete", what I want is the structure
'complete' to be changed to true when ANY of the visits have been
completed.
I have tried to implement SQL to do this, but it gives me the error

Hello All,
What I'm trying to do is update a child record using a parent-child relation. I want to find out if it is faster than than doing multiple selects.
Anyways, I've created a dataset (ds), have 2 datatables (dtRC and dtST). Created the parent-child relationship with multiple columns and added the
relation to the dataset.
Now what I want is to move through each of the dtRC (parent) records, get all related dtST (child) records...

Hi,
I have a stored procedure that has to extract the child records for
particular parent records.
The issue is that in some cases I do not want to extract all the child
records only a certain number of them.
Firstly I identify all the parent records that have the requird number
of child records and insert them into the result table.

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:
