Some people get confused.
A datareader can not have any amount of datatables.
Not even one of them.
Datatables exist by themmselves or inside a dataset, but
they are not generated nor filled by a datareader.
A datareader generates "only datarows", it doesn't generate
datatables. Each one of the datarows comply with a
structure as defined by the SELECT sql statement.
That SELECT statement may have columns that belong to one
or more "tables in the database". By example using a JOIN
or something similar. But listen well I said "tables" not
"datatables".
OK my friends?
