Hi,
I have 5 tables:
main
data1
data2
data3
data4
Each table has the field "name".
In a form, I want to write data in the "name" field to all the tables at the
same time.
Is this possible without complicated programming?
Regards, Wilfried (Belgium)

You could... but why? What data do data1-4 contain? Are they really
child tables of main?

Yes. It is extremely easy.
You remove the "name" field from each of the data tables and then you
only need to replace it once, in the main table.
Do a search in google on "normalization" . It will explain why you
will want to do it this way.

What about if the "name" is the foreign key he wants to
propagate to the additional records?

Oh, gosh. Here we go again.
A pox on keys that have real world meaning. A pox I say.

The table "main" contains the names and addresses.
tables "data1-4" are used to store data of 4 different contests
to make an overall calculation with the 4 data-tables, it is necessary that
they all contain the same names (with "0" in the other fields).
Now I do this myself, for each new name I open the 4 data-tables and type a
zero in the first field (the name is filled in automatically).

I can't do that Mike, the tables are linked together with the "name"-field.
To make some calculations with the data-tables, it is necessary to have the
names in all four the tables
(even when there is no data in the other fields)
thanks anyway,

The O.P. would have the same problem updating a number into the
foreign key field of the four tables, whether it's a number or a
name
A pox on autonumbers and a pox on those who use them instead of
a significant primary key.
And I'm not saying that the primary key should not be a numeric
ID, just that it should never be an autonumber.

What you need to do is go to the relationships view and set the
four "name" fields to relate to the name in your main table.
Mike Preston is correct in that you should assign a NameID field
to that table and use it instead, because you may occasionally
run into 2 John Smiths. There are 5 Robert Quintals in the local
phone directory.
Once you have your relationships, you set up a form to enter the
data in the main table, and you then add a subform for each of
the other four forms. The wizard should take care of
automatically populating the sub-tables.

Why didn't I think of that ;-)
It's so simple and I think you are absolutely right.
I'm going to try it out as soon as possible.
Many thanks to all of you.

I need to add data from two Excel sheets (both on the same workbook)

My sheets are quite large (~55,000 rows and 200 columns each) and I'll

Suppose if I have a SQL query like

The data adapter wizard allows you to add more than one
table, but that doesn't seem to work right when setting up
a dataset. Some of the documentation I have read states
that only one table should be selected per data adapter,
and then you use a DataRelation object to pull join them
together. Okay, if that's the case then fine, but why
would the data adapter allow you to add more than one
table if this is not how it is supposed to work....
