It’s important to know the SSRS interview questions if you want to have a great career in IT today. They will help you get through the toughest interview rounds.
SSRS stands for SQL Server Reporting Services. It’s a part of SQL Server that lets you use SQL Server and other data sources to make reports that can be sent to phones, printed, or shown visually. SQL Server is an RDBMS (Relational Database Management System) that helps with business intelligence, transaction processing, and analytics. The main responsibility of SSRS developers is to improve SQL Server queries to proficiently retrieve data. By learning SSRS, you have the expertise to design and develop databases.
This document provides a comprehensive guide to SSRS interview questions and answers for both freshers and experienced candidates. It covers various aspects of SSRS, including its architecture, data regions, report processing stages, new features, sub-reports, and integration with other servers. Additionally, it delves into advanced topics like data mining, running aggregates, query parameters, report caching, command-line utilities, deployment methods, and query storage.

Explain the various stages of Report Processing
The various stages of Report Processing include:
- Compile: This step looks at the expressions in the report definitions and saves the compiled format on the server.
- Process: It runs queries on datasets and combines intermediate format, layout, and data.
- Render: It sends a report that has been processed to an extension that renders to show how much information can fit on each page. The extension then makes the page report.
- Export: It exports reports to a different file format.
