Select the correct answerWhich of the following fields would not make a suitable primary key ?OptionsAn invoice numberA date fieldAn autoNumber fieldA customer’s social security number

To determine which of the following fields would not make a suitable primary key, we need to consider the characteristics of a primary key.

A primary key is a unique identifier for each record in a database table. It must be unique, meaning no two records can have the same value for the primary key field. It should also be stable, meaning it should not change over time.

Now let's evaluate each option:

1. An invoice number: This could potentially be a suitable primary key if it meets the criteria of being unique and stable. However, if there is a possibility of having duplicate invoice numbers or if the invoice number can change over time, it may not be a suitable primary key.

2. A date field: A date field is not typically suitable as a primary key because it is not guaranteed to be unique. Multiple records can have the same date, and dates can also change over time.

3. An autoNumber field: An autoNumber field is often used as a primary key because it automatically generates a unique number for each record. This makes it a suitable choice for a primary key.

4. A customer's social security number: A social security number is often used as a unique identifier for individuals. It is typically stable and unique, making it a suitable choice for a primary key.

Based on the above analysis, the field that would not make a suitable primary key is the date field.
