Select Distinct And Include Non-distinct Columns?

Apr 20, 2010

I would like to select a distinct query based on three fields and display the rest of the fields. For example,

I have firstname, lastname, address, city, state and zip, but I only want to use the distinct on these fields first and last name. However when i use the distinct function I get a distinct on all the selected rows. I just want to distinct firstname and lastname and display the other fields. for example,

Mary Smith New York
Mary Smithy New York
Mary Smith Maine

I would like the result to be:

Mary Smith New York
Mary Smithy New York

I don't care about Mary Smith Maine, because i am only using the distinct for "Mary Smith" firstname and last name and showing the city.

C# - How To Get Distinct Records In Datatable

Jul 20, 2010

I am using C# + VSTS 2008 + .Net + ASP.Net + IIS 7.0 + ADO.Net + SQL Server 2008. I have a ADO.Net datatable object, and I want to filter out duplicate/similar records (in my specific rule to judge whether records are duplicate/similar -- if record/row has the same value for a string column, I will treat them as duplicate/similar records), and only keep one of such duplicate/similar records.

The output needs to be a datatable, may output the same datatable object if filter operation could be operated on the same datatable object.

What is the most efficient solution?
