What is the purpose of the SQL UPDATE command?

The SQL UPDATE command is specifically designed to modify existing records within a database table. Its primary function is to change the values in specified fields for one or more rows that meet a given condition. This allows users to maintain accurate and current data without having to delete records and create new ones.

When executing an UPDATE command, a user must define which records to change (typically using a WHERE clause) and specify the new values for the fields that need updating. This operation is essential for managing data integrity in a database, such as correcting information or updating a status field as conditions change.

In contrast to other options, adding new records, deleting records, or creating new tables are accomplished using different SQL commands, namely INSERT, DELETE, and CREATE TABLE respectively. Therefore, the focus of the UPDATE command on modifying existing data makes it a fundamental tool in SQL for database management.
