Application of GROUPING_ID Function

• Hierarchical Reporting: GROUPING_ID() function can be used with GROUP BY and ROLLUP clauses easily to create hierarchical reports. It helps to distinguish between different grouping levels making it easy for the user to analyze the report.

• Conditional Aggregation: GROUPING_ID() function can be used along with the WHERE clause IN SQL Server to selectively aggregate data based on the grouping levels, allowing more flexible and customized analysis for the data.

• Trouble-Free Row Filtering: The desired rows from the result can be filtered easily with the help of GROUPING_ID() function. Just by using the GROUPING_ID()= n condition where n denotes the row number the rows can be easily filtered.

• Integration with Aggregate Functions: The GROUPING_ID() function can be easily combined with aggregate functions like SUM(), COUNT(), and AVG() to perform more filtered analysis on the data and fetch the desired results.

SQL Server is a Relational Database Management System that is used to create and manipulate the database. It provides advanced security measures like encryption, access control, and auditing to protect sensitive data from unauthorized access.

It Supports a wide range of data types, including structured, semi-structured, and unstructured data, for effective data storage and management. It also Supports various programming languages and offers tools like SQL Server Management Studio for simplified database administration and development.
