For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.Note: Keep in mind that this Update is different than a SQL UPDATE statement.

After that I called the Data Adapter's Update method to save the changes to the database table.

It turns out that when you need the Insert Command from the My Sql Command Builder you have to specify the rowstate as added.

The way the architecture works with the Data Adapter is that you can make any changes you want to the filled Data Set, and it won't affect the database until you call the Update method.
