Learn what a Primary Key is and how they help keep duplicate data out of our databases. Author Jen McBee will discuss Primary Keys and how to distinguish which fields in your database should be set as the Primary Key.
- [Voiceover] Hi, let's talk about Primary Keys…and I want to start off by saying that…every table in your database should have a Primary Key.…What's a Primary Key you ask?…Well it's the one field in your table…that will only hold a unique value for each record.…Examples of Primary Keys in tables…might be an employee ID number,…a Social Security Number,…or an order ID number.…Those are three instances where we would never want…to have a duplicate entry in that particular field.…
On the Access 2013 MOS exam,…you'll be asked to assign a Primary Key property…to a field in a table.…You may also be asked to reassign…that Primary Key from one field to another.…We'll cover both scenarios in this video…so you'll be prepared to conquer that task.…I have the 02-02 exercise file open.…In this database, we have three tables.…We have a Customers table,…an Orders table,…and a Products table.…
Let's open the Customers table…and look at the fields that have been created.…In this table we have a Customer ID field,…Company, Last Name, First Name, etcetera.…
