What is the primary function of the INSERT command in a database?

The primary function of the INSERT command in a database is to add rows to a database table. This command is fundamental in SQL (Structured Query Language) as it allows users to populate their tables with new records, which are essential for creating and maintaining a database.

When you execute an INSERT statement, you specify the table you want to add data to and provide the values for the fields of the new row. It’s a critical operation in any database management system because without the ability to insert data, a database would remain empty and useless. The ability to add new data is what makes a database dynamic and functional.

The other options relate to different SQL commands and their purposes. For instance, removing rows pertains to the DELETE command, modifying existing rows refers to the UPDATE command, and filtering data based on conditions is performed using the SELECT statement with WHERE clauses. Each of these commands serves a distinct role in managing and querying data, but INSERT specifically focuses on the addition of new data.
