What are the different methods to assign any field as primary key in a table?
There are several methods to assign a primary key in a table, including: Single-column primary key: Designate a single field (e.g., an ID number) as the primary key to uniquely identify each record. Composite primary key: Use a combination of two or more columns to create a unique identifier, ensuring that the combination of values is unique across the table. Auto-incrementing primary key: Implement a field that automatically generates a unique value (such as an integer) for each new record, commonly used in databases like MySQL. Unique constraints: Define a field with a unique constraint to enforce uniqueness, which can also serve as a primary key if it meets the requirements.
