I have no idea what language you are talking, but whatever it is is
doesn't seem to have much relationship to the language of MySQL (or
indeed just about any other database system).
A table has rows. A dataset is a term used in IBM mainframes to refer
to a file.
In a table a "row" cannot be integer. A row is made up of fields and
one (or more) of those fields can be an integer data type.
A key is a way to uniquely identify a row in a table.
So, would you like to have a read up on what terms you should be using
and then try asking your question again, this time in a way that makes
some sort of sense?
