When I build data access layers, I like to define a const for each column in the query like this:

const int CLIENTID = 0; const int STATUS = 1; const int FIRSTNAME = 2;

That way, I can pull data like this:

newClient.Name.FirstName = reader.GetString(FIRSTNAME);

And if something changes in the database, I know I only have to change the field that FIRSTNAME references.

However, sometimes, tables can be quite large and it becomes a pain in the wrist.  So I wrote a class that uses the EnterpriseLibrary and builds the code that defines the const for each column.  Then I can copy and paste it into my code:

This class can be consumed like this:

ExtractFieldNames x = new ExtractFieldNames("myConnectionString"); textBoxResults.Text = x.ExtractConstantsFromTable("myTableName);

The article with the class is here.
