That is, it can be in an error state after you finish updating one column but before you get to the next one.To prevent premature constraint violations you can temporarily suspend update constraints.If you intend to update an underlying data source later, you must use the methods on the Data Table.Data Row Collection property when adding or removing rows.

Merging datasets is useful when you have a local dataset and you get a second dataset from another application.

You can use Microsoft Access as a front end to a My SQL database by linking tables within your Microsoft Access database to tables that exist within your My SQL database.

When a query is requested on a table within Access, ODBC is used to execute the queries on the My SQL database instead.

If you aren't using data binding, and are saving changes for related tables, you have to manually instantiate a variable of the auto-generated Table Adapter Manager class, and then call its Udpate All method.

Two-stage update process and the role of the Data Row Version in a successful update A dataset contains collections of tables, which contain a collections of rows.

(A concurrency violation occurs when another user modifies a record in the data source after the dataset has been filled.)To make changes to an existing data row, add or update data in the individual columns.
