He helps with DataSet and DataTable

I am new in .Net and I am learning in C # and I need help me with the
following,
Certainly I thank your help.

When one connects to a motor of data base like SQL Server
And only one wants to extract a certain columns use the following.

SELECT productid, nomprod, price FROM product WHERE productid = 1

The above extracts of the table "product" only the columns "productid,
nomprod, price" than in the column "productid = 1"
I am charging the data in a DataSet from .xml file
Now then I understand that a dataset is not a motor of data base or a
data base
the subject is, as I make a consultation like the previous? That only
certain columns be given back to me
How to do the consultations SELECT in one DataSet and DataTable?

Thanks.

Hi, I've got a simple console app that just reads an XML file into a DataSet then prints out a description of each table in the DataSet, including column names and row values for each column.

This is a question that someone familiar with ASP.NET and ADO.NET DataSets and DataTables should be able to answer fairly easily. The basic question is how I can efficiently match data from one dataset to data in a second dataset, using a common key. I will first describe the problem in words and then I will show my code, which has most of the solution done already. I have built an ASP.NET that queries an Index Server and returns a...
