I seem to always want to do this type of join, but I can never find
how to do this.
I am trying to join two tables. The parent table will always have one
row of data and the child may have 0 to 45 rows of data. I am trying
to join the tables in an outer join, so if 0 rows in child it is not
affected. But I only want one row returned of the child.
How do I do this in mySQL?

I have a parent table that has one child table. The parent has a single
field (ID, AutoIncrement, Seed 0, Step -1 in the DataSet, Seed 1, step
1, in DataSource). The child is linked to this ID column in the parent.
I have the parent fields in textboxes and the child is a DataGrid. When
I add a new parent record, then go to add child records, I am getting an
exception that says, "ForeignKeyConstraint requires the child key values
(0) to...

Dear Group,
I'm having problems retrieving the child rows of a parent row. The parent
table is Users and the child table is Addresses. I used the Schema to
create a DataRelation between the Primary Key of the parent table and a Long
Integer field of the child table. I allowed default (which defaults to
Cascade) in the relationship. The relationship is titled "drlnUserAddress".
I always get a return of 0 child rows and there are four...

Hi,
We are working on a gridview inside the gridview (parent-child) scenario.
The data of child grid will depend on the data of parent.
Objectives:
1.Add new row in parent grid after each row and add child grid into that row
because the columns in child grid are same as parent grid and we want to
align them with the cols of parent grid.
2. If there is data for child grid we show a plus image in the parent row
(in the row above the...

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 guys, I'm trying to create an HTML page that contains two frames.
The bottom frame should simply be some website, but the top frame needs
to have a close link to kill the window. I tried calling
'document.window.close()' from the child frame, but without success. I
then tried putting the 'close()' call in the parent page and calling it
from the child, but still without success.
Can anyone take a look at the HTML/Javascript below and...

I' m setting up a parent/child datagridviews in a form.
I am doing a lot of this by hand coding in order to get the feel of things.
I want a change in the parent table to trigger a change in the child.
Where is the best place (if I cannot set it up to be automatic through
relationships) to catch the change in the parent to refetch the child rows?
