5,904 PointsCan I INSERT an entry with a primary key into a table if previously there was an entry with same primary key deleted?
Here's the example: I have a table called Products. I have an entry with a primary key of "4". I delete the entry with primary key of "4". Can I now add an entry with primary key of "4"?
