SSRS Interview Questions And Answers For Experienced Pdf
1. How to send an SSRS report from SSIS?
Answer: Often there is a requirement to be able to send an SSRS report in Excel, PDF or another format to different users from an SSIS package once it has finished performing a data load. To do this, first, you need to create a subscription to the report. You can create an SSRS report subscription from the Report Manager. At the report subscription, you can mention the report format and the email address of the recipient. When you create a schedule for the SSRS report, a SQL Server Agent Job will be created. From the SSIS, by using sp_start_job and passing the relevant job name you can execute the SSRS report subscription.
2. What are things to consider before Caching, Snapshots, or Subscriptions?
Before you schedule any caches, snapshots, or subscriptions, Make sure:
- SQL Server Agent is running
- There are proper Execution Accounts
- Account Credentials are stored in the report server
- The schedule properly follows the requirements
3. Can you import Microsoft Excel data to SSRS?
Answer: Reporting Services does not import data. It only queries data in whatever format it is stored in its native storage system. I will assume that you’re asking whether you can create reports and use Excel spreadsheets as data sources. The answer is Yes, Reporting Services supports a wide variety of data sources, including Excel files. You’ll get the best performance with the built-in native .NET providers but you should be able to connect to any ODBC or OLE-DB data source, whether it comes from Microsoft or a third-party company.

6. What is a Report Server Project?
Answer: It is the project template used to create Managed Reports. It includes all of the functionalities that developers need to retrieve data, transform it using code, and create Managed Reports or embedded reports.
7. What are Managed Reports?
Answer: A Managed Report is for users who know how to use all of the aspects of the reporting tool.
They are Enterprise Reports that are managed by the SQL Developers up until the finished product.
These users know the structure of the underlying data and they know how to retrieve the data. These reports are code-based for developers. You use the Report Designer to make Managed Reports.
8. How Would You Go About Developing A Ssrs Report?
Answer: The general development methodology for an SSRS report is to start by creating a data source. Based on the data source create one or multiple datasets as needed for parameters and the body of the report. Add required controls from the toolbox which would act as a container for the fields in the dataset. Format the controls added to the report body. Verify and validate the report and finally deploy the report.
9. What is a Report Model Project?
Answer: It is the VS project template used to create Ad Hoc Reports. It allows the developer to create a basic model (.SMDL file) that is the input of the Report Builder. The model is a container for metadata.
The non-technical user can then use the Report Builder to make an Ad Hoc Report show whichever data they want. Model → Report Builder → Ad Hoc Report.
10. What Is Reporting Lifecycle?
Answer: Generally, Reporting Services has three main three phases:
Development of Reports (Developer): at first reports need to be developed and it is done the developers.
Management of Reports (DBA): When the Report is being developed DBA ensure the following things:
Security: only authorized user should access the report
Execution: how the report will be executed to optimize data sources performance
Scheduling of Reports: so that report is executed on scheduled timings
Report Delivery (DBA + Developer): When the report is being developed and executed the report is transferred to the business users. They use it and if any modification is required the report goes back to the development stage.

Answer: Business Intelligence Development Studio is generally used to deploy SSRS reports. There is no out-of-box support in SSRS to automate reports deployment, but free third-party products like RSScripter can be used for this.
14. What is a report subscription?
Answer: Subscriptions are standing requests to deliver report data to requested recipients. Once the report is being subscribed and the subscriber will get updates from the report server on a scheduled interval.
15. Explain how you can deploy an SSRS report?
Answer: SSRS report can be deployed in three ways
By Visual Studio: You can directly deploy the report in Visual Studios through solution explorer, by declaring the report server URL in project properties at Target Server URL.

19. When to Use Null Data-driven Subscription?
Answer: Create a data-driven subscription that uses the Null Delivery Provider. When you specify the Null Delivery Provider as the method of delivery in the subscription, the report server targets the report server database as the delivery destination and uses a specialized rendering extension called the null rendering extension. In contrast with other delivery extensions, the Null Delivery Provider does not have delivery settings that you can configure through a subscription definition.

Answer: The Report Server Database Configuration Wizard allows you to change the settings of the database that holds the Report Server. With it, you connect to the database server with your credentials. Then, you can change the Database Name, language, and Report Server Mode (Native or SharePoint).
23. How do users use Report Builder with SQL Server data sources?
Answer: While models that provide access to SQL Server Analysis Services are automatically generated on the report server, the Report Builder Model Designer can be used to generate or modify the models that are built on top of SQL Server relational databases. These model-building projects are a new type of project within a Visual Studio-based development shell.
24. How to fine-tune Reports?
Answer: To tune-up, the Reporting Services, follow the below mentioned ways: – Expand the Server or utilizing the reporting services of another database server. For better embedding of report contents, report application’s logic and characteristics can have a duplicate copy of data. – Replication of data continuously. Using (nolock), the issues of locking can well be resolved and the performance of the query can be improved. This can be done by using dirty read at the time of duplicating the data is unavailable.

32. Explain how would you store your query in an SSRS report or a Database server?
Answer: Storing SQL queries directly in text format in the data should be avoided. Instead, it should be stored in a stored procedure in the database server. The advantage is that the SQL would be in a compiled format in an SP and gives all the benefits of SP compared to using an ad-hoc query from the report.
