ADO.NET serves as a powerful framework for establishing database connectivity between various systems, whether they are relational or non-relational, by utilizing a common set of components. Among these components, the SqlDataAdapter class plays a significant role in bridging the gap between disconnected DataTable objects and the underlying physical data source.
The SqlDataAdapter class provides a range of special features that enhance its functionality. By exploring the following C# programs, you will gain insights into these features and understand how to utilize them effectively:
Populating a DataTable using the SqlDataAdapter
This program demonstrates how to retrieve data from a database using a SqlDataAdapter and populate a DataTable with the retrieved results. This allows for efficient and flexible data manipulation within a disconnected environment.
Updating changes from a DataTable to the database
This program showcases the process of updating changes made to a DataTable back to the database using the SqlDataAdapter. By using the SqlDataAdapter's Update method, you can easily propagate modifications made to the DataTable to the corresponding database table.
Performing batch updates
This program illustrates how to perform batch updates using the SqlDataAdapter. Batch updates allow you to optimize performance by reducing round trips to the database, as multiple changes can be sent together in a single batch.
Handling concurrency conflicts
This program demonstrates how to handle concurrency conflicts when updating data using the SqlDataAdapter. Concurrency conflicts occur when multiple users attempt to modify the same data simultaneously. The SqlDataAdapter provides mechanisms to detect and resolve such conflicts, ensuring data integrity.
By exploring these C# programs, you will gain practical experience and a deeper understanding of the special features offered by the SqlDataAdapter class in ADO.NET.
