## sorry for the noob question but what is the overall role of a\*\* “Set as Primary value”\*\*? I tried to look for an exhaustive explanation in the documentation, but there is nothing specific explained: [https://docs.nocodb.com/setup-and-usages/tables](https://docs.nocodb.com/setup-and-usages/tables)

#### It is used for uniquely identifying value within column. Just like primary key but humanly readable. When connecting to existing dB, a column adjacent to primary key is auto selected as primary value. And this can be changed in the GUI. Will make it part of docs.

#### +1 question: does the primary value span across the db or only the table it is part of, and what happens if I cross-link tables?
