Here is a sample I wrote that someone requested I post.
Right click HERE and do a "Save As" or "Save Target As".
The sample gets an IDataReader on a Source Datastore (Access/Jet database), populates a strong dataset, then after so many records, ships the DataSet.GetXml() to a sql server stored procedure.
This should run faster than doing a row by row get/insert that alot of people code up.
Yes, there are many ways to do bulk inserts/imports with Sql Server. I chose this one because in my real life code, I need to run the rows through some business rules before importing.
Enjoy.
