    Remarks
    You can use ExecuteNonQuery method to perform catalog operations (for example, querying the structure of a database or creating database objects such as tables); or to change the data in a data source, without using a DataSet, by executing UPDATE, INSERT, or DELETE statements.

    Although ExecuteNonQuery does not return any rows, any output parameters or return values mapped to parameters are populated with data.
