Description: The row number is a unique identifier assigned to each row in a result set within a database. This number allows users and database management systems (DBMS) to refer to specific records efficiently. In the context of relational databases, each row represents a set of related data, and the row number facilitates the organization and access to this data. It is often used in SQL queries to identify and manipulate records, allowing operations such as updating, deleting, or selecting specific data. Additionally, the row number can be crucial in result pagination, where only a subset of rows is displayed at a time, thus enhancing the user experience when interacting with large volumes of information. In summary, the row number is a fundamental tool in data management, providing a clear and structured method for accessing and manipulating information across various types of databases.
