DataAdapter Fill Method

I open one SQLConnection,create a SqlDataAdapter and SqlDtaSet
and then run some queries with ExecuteNonQuery method of
SqlCommand object.When i use Fill method of DataAdapter
object,it adds all data from the source table and did not
add only changed data.For example if i call tree time Fill
method,DataSet's corresponding table contains tree record for each
one record in data source table.

Please help me.
