You can use ExecuteNonQuery to change the data in a database
without using a DataSet. Do this by executing UPDATE,
INSERT, or DELETE statements.
Although ExecuteNonQuery does not return any rows, output
parameters or return values that are mapped to parameters
are populated with data.
For UPDATE, INSERT, and DELETE statements, the return value
is the number of rows affected by the command. For all other
types of statements, and for rollbacks, the return value is -1.
