However, if the Missing Schema Action property is set to Add With Key, appropriate primary keys, and constraints are also created.

If the data adapter encounters duplicate columns while populating a Data Table, it generates names for the subsequent columns, using the pattern "columnname1", "columnname2", "columnname3", and so on.

In addition to reducing the load on the data server by reducing the number of active connections, the data server's load was also reduced because activities performed on disconnected data had no impact on the server.

If the connection is closed before Fill is called, it is opened to retrieve data, and then closed.

If the connection is open before Fill is called, it remains open.

If a primary key exists, incoming rows are merged with matching rows that already exist.

If no primary key exists, incoming rows are appended to the Data Table.

The Command object is used to submit SQL statements or to execute stored procedures. NET Command object accepts parameters and supports re-executing compiled commands.

This had lots of advantages, not the least of which was that we could close our application's connection to the data source and still work with the data.

The object provides four properties that allow us to control how updates are made to the server: Select Command, Update Command, Insert Command, and Delete Command.

If the incoming data contains unnamed columns, they are placed in the Data Set according to the pattern "Column1", "Column2", and so on.
