GetUpdateCommand
SqlCommand updateCommand = CommandBuilder.GetUpdateCommand();
Returns a reference to the automatically generated
Command object, which updates data within the data
source when the Update( ) method of the data
adapter is called.
If the SELECT command that is the basis of the automatically
generated UPDATE command is changed, the RefreshSchema( ) method must be called. Otherwise the
GetUpdateCommand( ) method returns a statement for
the previous schema.
Calling one of the GetDeleteCommand( ),
GetInsertCommand( ), or GetUpdateCommand( ) methods or the Update( ) method of the
DataAdapter, generates all delete, insert, and
update command logic.
