Data 　(i). Description There is a problem with programming: Occasionally, for some reason, a database table needs to be changed to a field name. For example: change: Name to: PersonName. The programmer then turns on all the code involved and finds

The DataAdapter Update method is used to parse changes in the dataset back to the data source. Like the Fill method, the Update method uses an instance of the DataSet and an optional DataTable object or DataTable name as parameters. The dataset

In the case of unit tests for data access, which typically add data records, the data set will typically be: Then, in the test method, verify that the test method executes correctly by verifying the number of new records or the contents of the

L Example 3 shows how to use text processing technology to extract a location or address from the title or description of an RSS source to create a mashup. In this case, the location information cannot be used directly. Some text processing is required to obtain an address, city, region, or ot
