What is a Primary Value ?

• Primary value as the name stands is the primary or main value within a row of a table that you generally associate that row with.
• It should be usually associated with a column which is uniquely identifiable. However, this uniqueness is not enforced at the database level.

What is the use of Primary Value ?

• Within a spreadsheet, primary value are always highlighted so that it is easier to recognise what row we are in.
• And when LinkToAnotherRecord is created between two tables - it is the primary value that appears in LinkToAnotheRecord column.

Example : Primary valuehighlighted in actor table

Example : Primary value highlighted in film table

Example : Primary value associated when LinkToAnotherRecord is created

How is Primary value identfied for existing database tables ?

• It is usually the first column after the primary key which is not a number.
• If there is no column which is not a number then the column adjacent to primary key is chosen.

Can I change the Primary Value to another column within tables ?

• Yes, you can. Hover over column which you want as primary column and click Set as Primary Value
