is it possible to assign two primary key in a table
Answer Posted / jd
At the end of the day a primary key is unique non null value
that the data is indexed upon.
Even if only one column can be explicitly defined as the PK.
It is possible to uniquely identify a row differently, by
creating a unique non null column that is indexed. It is
implicitly then a PK.
