Re: Student asks about Tuples and Relations (SQL Problem)

Generally speaking, no. While some database managers may provide this feature, none of the databases that I work with do, and there are certainly no standards in this area.

I have always explicitly stored the date and time of row creation as a column in the table when the design dictated the need for this information.
