Yes, we can do that. But data from all adapters will get
filled in the same default datatable of the dataset.
That is, when we fill dataset with one adapter, the contents
got filled in the table, and when we fill the same dataset
again with the different adapters, the rows retrieved are
appended to the already existing table of the dataset.
So, if you want to just fill the dataset, you can do this,
but obviously, this won't be useful in other scenarios.
