>Say I have a dataset of one table with one row. And I need to create an UPDATE command to pass to a stored procedure. So far, in the book I am reading, I only found a way to do it by creating SQL parameter object and adding a parameter for each column that has been changed. And I don't know how to determine which columns have been change in a generic way. Does it make sense? TIA.

Normally I would create an update SP that has parameters for all fields that could be updated, and pass those fields back whether they were updated or not. In general, that winds up being all fields for a table aside from the primary key.
