Hello,

What is meant by "first row"?

Sequential files have a first and last record, but databases do not have the same.

Keep in mind that most database processing is done via one or more keys. There is no "first".

Hello,

That will fetch one record - not sure i understand how that would be "the first row from a table"

. It would be the first row that particular query fetches, but that does not imply the first row in the table.

As i mentioned earlier, until what "first row" really means is defined, there is no way to read it and besides, there is not a "first row in the table" concept in most database systems.
