Interview Questions for Reporting Services - Freshers, Experienced

 

Q: What is SSRS?
SQL Server Reporting Service is one of the server-based software systems that generate reports developed by Microsoft. It is used for preparing and delivering interactive and variety of printed reports. It is administered through an interface that is web based. Reporting services utilizes a web service interface for supporting and developing of customized reporting applicatons. It can be competed with Crystal Reports and other business intelligence tools.

Q: Explain SSRS Architecture?
Reporting services architecture comprises of integrated components. It is a multi-tiered, included with application, server and data layers. This architecture is scalable and modular. A single installation can be used across multiple computers. It includes the following components: - Report Manager, Reporting Designer, Browser Types Supported by Reporting services, Report server, Report server command line utilities, Report Server Database, Reporting Services Extensibility, Data sources that is supported by Reporting Services.

Q: Explain Reporting Life Cycle?
The Reporting Lifecycle includes - Report designing – The designing is done in Visual Studio Report Designer. It generates a class which embodies the Report Definition. - Report processing – The processing includes binging the report definition with data from the report data source. It performs on all grouping, sorting and filtering calculations. The expressions are evaluated except the page header, footer and section items. Later it fires the Binding event and Bound event. As a result of the processing, it produces Report Instance. Report instance may be persisted and stored which can be rendered at a later point of time. - Report Rendering: Report rendering starts by passing the Report Instance to a specific rendering extension (HTML or PDF formats). The instance of reports is paged if paging supported by output format. The expressions of items are evaluated in the page header and footer sections for every page. As a final step, the report is rendered to the specific output document.

Q: How to finetune Reports?
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.

Q: What are Data Driven Subscriptions?
Reporting Services provides data-driven subscriptions so that you can customize the distribution of a report based on dynamic subscriber data. Data-driven subscriptions are intended for the following kinds of scenarios: Distributing reports to a large recipient pool whose membership may change from one distribution to the next. For example distribute a monthly report to all current customers. Distributing reports to a specific group of recipients based on predefined criteria. For example send a sales performance report to the top ten sales managers in an organization.

Q: What is Linked Report?

Q: What are different types of roles provided by SSRS?

Q: Difference between Logical Page an Physical Page in SSRS.
Logical page breaks are page breaks that you insert before or after report items or groups. Page breaks help to determine how the content is fitted to a report page for optimal viewing when rendering or exporting the report. The following rules apply when rendering logical page breaks: Logical page breaks are ignored for report items that are constantly hidden and for report items where the visibility is controlled by clicking another report item. Logical page breaks are applied on conditionally visible items if they are currently visible at the time the report is rendered. Space is preserved between the report item with the logical page break and its peer report items. Logical page breaks that are inserted before a report item push the report item down to the next page. The report item is rendered at the top of the next page. Logical page breaks defined on items in table or matrix cells are not kept. This does not apply to items in lists.

Q: User want only to display only pdf as export option in report Manager. How to acheive this?

Q: Name and Describe few console utilities for SSRS?

Q: Name few Endpoints exposed by SSRS 2012?

Q: Describe different Processing Modes offered by SSRS?

Q: When to Use Null Data driven Subscription?
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.

Q: How can you monitor the report Usage?

Q: How does the report manager work in SSRS?
Report manager is a web application. In SSRS it is accessed by a URL. The interface of this Report manager depends on the permissions of the user. This means to access any functionality or perform any task, the user must be assigned a role. A user with a role of full permissions can entire all the features and menus of the report. To configure the report manager, a URL needs to be defined.

Q: What are the Reporting Services components?
Reporting services components assist in development. These processing components include some tools that are used to create, manage and view reports. A report designer is used to create the reports. a report sever is used to execute and distribute reports. a report manager is used to manage the report server.

Q:SQL Server Reporting Services vs Crystal Reports.
Crystal reports are processed by IIS while SSRS have a report server. Caching in Crystal reports is available through cache server. On the other hand, caching in SSRS is available for Report history snapshots. Crystal reports have standards and user defined field labels. SSRS allows only user defined field labels.

Q: What is Report Builder?
Report Builder is a business-user, ad-hoc report design client that allows users to design reports based on the business terms (Report Builder model) they are familiar with, but without needing to understand database schemas or how to write SQL or MDX queries. Report Builder works with both SQL Server and Analysis Services data sources.

Q: How does Report Builder support Analysis Services cubes?
Report Builder supports relational SQL and Analysis Services data sources in SQL Server. To create a model for Analysis Services cube, go to Report Manager or Management Studio, create a data source for your Analysis Services database, and then select the Generate Model option to create the model.

Q: How do users use Report Builder with SQL Server data sources?
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.

Q: How do I get Report Builder to generate a parameter that can be set by users viewing the report?
In the filter dialog box, click the name of the criteria that you would like to prompt the user for when viewing the report. For example, for the criteria Order Year=2000, click Order Year. Select the Prompt option in the drop-down list.

Q: What new data source types were added in SSRS 2014?
In addition to the data source types available in SSRS (SQL Server, Oracle, ODBC, OLE DB), the following have been added in SSRS 2012: SQL Server Analysis Services SQL Server Integration Services SQL Server Report Builder Models XML (through URL and Web services)

Q: How can I add Reporting Services reports to my application?
Visual Studio / SSDT / BI Data Tools (Standard and Enterprise editions) contains a set of freely redistributable Report Viewer controls that make it easy to embed Reporting Services functionality into custom applications. Two versions of the Report Viewer exist, one for rich Windows client applications and one for ASP.NET applications.

Q: Do I need a report server to run reports in my application?
In addition to publishing reports to a report server, you can build reports using the Report Designer that is directly integrated with Visual Studio language projects. You can embed reports directly in any Windows Forms or ASP.NET Web application without access to a report server. The data access in embedded reports is a natural extension of the Visual Studio data facilities. Not only can you use traditional databases as a source of data for your reports, you can use object collections as well.

Q: Can you import Microsoft Excel data to SSRS?
Reporting Services does not import data. It only queries data in whatever format it is stored in their 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.

Q: Can we deploy SSRS reports on our personal website?
Your reports can only be deployed on a reporting services site. Your only option for viewing them from other sites is an HTTP link. Some tools, like SharePoint offer controls allowing you to view reports in the context of the other websites, but the report is still deployed to and hosted from reporting services.

Q: Can we use datagrids for our report in SSRS?
We have an ASP.NET project that populates a datagrid. Using datagrid as my datasource for my report using SQL Server Reporting Services. Is this possible? The simple answer is no. However, nothing's ever simple. A set of reporting controls was added in Visual Studio 2010 allowing you to report in a dataset, on data that was supplied by you. So, if you retrieved your data into a dataset, bound the datagrid to the dataset so it had data to display, you could then use that dataset as the datasource for the reporting controls. These are then client-side reports, not server reports though.

Q: What are the drawbacks of reporting in SSRS?
For many years, Microsoft had no direct solution for reporting with the SQL Server besides Crystal Reports. Now, they have SQL Server Reporting Services, but it does have several drawbacks. It is still complex to understand the complete functionality and structure of this new component, and many users are still relying on the reporting application they are more familiar with, which is Crystal Reports. Also, components in SSRS like Report Builder and Report Designer are meant for different users for different aspects of the report process, yet complete understanding and exposure to both is important to utilize both functions fully and extensively. There are also issues when exporting very large reports to Microsoft Excel, as it can lead to a loss of data.

Q: Will running SSRS on Windows XP limit the number of users?
Yes, but not because of SSRS. The Internet Information Services (IIS) component of Windows XP only allows a small number of users to connect to the website at once. As SSRS runs via IIS, this would prevent more than a few people from using SSRS at once. Also, the only edition of SSRS that will install on Windows XP is the Developer Edition. This edition can not be used for production use. You need Standard or Enterprise Edition for production use, which requires a Server OS to install on (Windows 2003 Standard, Windows 2008 Standard, etc).

Q: Are there issues when exporting SSRS reports into Microsoft Excel?
When my users are trying to export a SSRS report into Microsoft Excel, one or two columns in the report appear to merge together. Why might this be? Exporting from SSRS is not always perfect, even if you stay within the Microsoft range of products. If you have extra resources, you could splurge for an add-on that offers much better control over exporting to Excel, such as OfficeWriter. From my experience, though, it is usually headers or footers that cause exporting issues. If any of these headers or footers overlap with data columns in your report, you will find that the exported version of the report has merged cells. Also, check columns next to each other to make sure that there is no overlap, as well.

Q: How to send a SSRS report from SSIS?
Often there is a requirement to be able to send a SSRS report in Excel, PDF or another format to different users from a SSIS package one it has finished performing a data load. In order to do this, first you need to create a subscription to the report. You can create a SSRS report subscription from 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.

28) Mention what method you can use to reduce the overhead of Reporting Services data sources?
Cached reports and Snapshots can be used to reduce the overhead of Reporting Services Sources.

 

29) Explain what is the difference between Tabular and Matrix report?
Tabular Report: Tabular report is the most basic type of report. Each column relates to a column chosen from the database
Matrix Report: A matrix report is a cross-tabulation of four groups of data.

 

30) Explain how would you store your query in an SSRS report or a Database server?
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.

 

31) What are the different kinds of SSRS Reports?
Reports can be categorized into operational and analytical reports. The distinction is based on the source of data and level of analysis facilitated by any particular report. Operational reports are based on OLTP sources and are static reports and Analytical reports are based on OLAP sources and generally facilitate drill-down and drill-through for analysis. Technically, SSRS reports can be categorized into parameterized, linked, snapshot, cached, etc...

 

32) What are parameterized reports? What are cascading parameters in SSRS reports?
Reports that accept parameters from users to fetch and report data conditionally are known as parameterized reports. When you have multiple parameters in a report and values of different parameters are dependent and populated dynamically based on the value of parent parameters, it's known as a cascading parameter.

 

33) How would you go about developing a SSRS report?
General development methodology for a 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.

 

34) What is a dataset and what are the different types of datasets?
A dataset is similar to a query definition, which is executed when the report is executed. Datasets are of two types: Shared and Embedded. An embedded dataset is private to the report in which it exists and shared datasets can be shared across reports.

 

35) Would you store your query in a SSRS report or a Database server? State the reason why?
Storing SQL queries directly in text format in the dataset should be avoided. Ideally it should be stored in a stored procedure in the database server. The benefit is that the SQL would be in a compiled format in a SP and brings all the benefits of using an SP compared to using an ad-hoc query from the report.

 

36) What is Tablix?
A Tablix can be seen as a control with combined capabilities of a table and a matrix, which facilitates asymmetric and flexible, row and column level, static and dynamic groupings.

 

37) How would you access SSRS reports deployed on report server?
Reports Manager is the most straight-forward way to access SSRS reports deployed on report server. Apart from executing the reports, it is the main administration console for SSRS server to manage reports.

 

38) Have you used the Report Viewer control / web part? What are the limitations?
The report viewer control / web part is the basic control to integrate SSRS reports with external applications. Using these interface applications can link and display SSRS reports within the application. The parameters toolbar in these controls have a limited programmable interface to decorate and blend it with the theme of the application.

 

39) Which is the latest version of SSRS and what are the new enhancements?
SSRS 2008 R2 is the latest RTM version of SSRS. Rich data visualizations, better programming functions for lookup and aggregation, improved performance and better control over exported data are some of the major enhancements.

 

40) What is Report Builder?
Report Builder is an ad-hoc report authoring tool primarily targeted to be used by business analysts to facilitate self-service report authoring. Report Builder 3.0 is the latest version available as of date.

 

41) How would you deploy SSRS Reports using out-of-box functionality and how can you automate SSRS report deployment?
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.

 

42) What is drill-down and drill-through in SSRS?
Drill-down is a mechanism of decomposing summarized information to a detailed level. Drill-through is a mechanism of decomposing the problem by drilling information generally using more than one report.

 

43) You want to include an image in a report. How do you display the Image Properties dialog box?
When you drag an image item from the Toolbox window to the Report Designer, the Image Properties dialog box automatically opens.

 

44) You want to configure an amount to display the value in a currency format. Which property do you use?
To configure an amount to display a value in a currency format, select the report item, and then set the format property to C or c.

 

45) What are data regions?
Data regions are report items that display repeated rows of summarized information from datasets.

 

46) You want to generate a report that is formatted as a chart. Can you use the Report Wizard to create such a report?
No, the Report Wizard lets you create only tabular and matrix reports. you must create the chart report directly by using the Report Designer.

 

47) You want to use BIDS to deploy a report to a different server than the one you chose in the Report Wizard. How can you change the server URL?
You can right-click the project in Solution Explorer and then change the Target-Server URL property.

 

48) Which rendering formats are affected by the PageSize properties?
Because only the Adobe PDf file, Word, and Image rendering extensions use physical page breaks, they are the only formats that are affected by the PageSize properties.

 

49) Can you use a stored procedure to provide data to an SSRS report?
Yes, you can use a stored procedure to provide data to an SSRS report by configuring the dataset to use a stored procedure command type. However, your stored procedure should return only a single result set. If it returns multiple result sets, only the first one is used for the report dataset.

 

50) You want to use a perspective in an MDX query. How do you select the perspective?
Use the Cube Selector in the MDX Query Designer to select a perspective.

 

51) Can you use data mining models in SSRS?
Yes, you can use the DMX Designer to create data mining queries for SSRS reports. However, do not forget to flatten the result set returned by the DMX query.

 

52) You want your report to display a hyperlink that will take users to your intranet. How do you configure such a hyperlink?
Create a text box item, set the action to Go To URL, and then configure the URL.

 

53) You want a report to display Sales by Category, SubCategory, and Product. You want users to see only summarized information initially but to be able to display the details as necessary. How would you create the report?
Group the Sales information by Category, SubCategory, and Product. Hide the SubCategory group and set the visibility to toggle based on the Category item. Hide the Product category group and set the visibility to toggle based on the SubCategory item.

 

54) You want to create an Excel interactive report from SSRS. In SSRS, can you create the same interactive experience in Excel that you would have on the Web?
No, you cannot create the same experience with SSRS. you can, however, use Excel to create such an experience.

 

55) What is the main difference between a Matrix report item and a Table report item?
The main difference between a Matrix and a Table report item is in the initial template. Actually, both report items are just templates for the Tablix data region.

 

56) When you do not use report caching, is it better to use parameters to filter information in the query or to use filters in the dataset?
From a performance perspective, it is better to use parameters because they let SSRS pull filtered data from the data source. In contrast, when you use filters, the queries retrieve all data and then filter the information in an additional step.

 

57) How do you configure a running aggregate in SSRS?
You can use the RunningValue function to configure a running aggregate.

 

58) What is the main purpose of a report parameter?
The main purpose of a report parameter is to add interactivity to your reports, letting users change the report behavior based on options they select.

 

59) What is the main purpose of a query parameter?
The main purpose of a query parameter is to filter data in the data source.

 

60) You want your users to select a parameter from a list of values in a list box. How should you configure the parameter?
You should create a data source that contains the possible values and then bind the data source to the parameter.

 

61) What is the main benefit of using embedded code in a report?
The main benefit of using embedded code in a report is that the code you write at the report level can be reused in any expression in the report.

 

 

 

62) What programming language would you use to create embedded functions in SSRS?
An SSRS report supports only visual Basic .nET embedded code.

 

63) Do you create your reports using the wizard or manually?
As with most Microsoft tools, SSRS includes a wizard that helps you create reports. The wizard is great for people who are new to the product, but it’s not good if you can’t go beyond the tools and create a report from scratch. Before you go for your interviews, make sure you can create a report from scratch without any wizards or tools to create them for you. Most companies need someone who can customize reports, and wizards leave room for very little customizations.

 

64) What are query parameters?
Query parameters are the parts of an SQL query that allow you to filter results. Parameters are contained in the SQL’s “where” clause. These parameters tell the SQL server which records you want to update, select, or delete. In other words, if it wasn’t for the where clause parameters, you would affect all records in your tables.

 

65) What is a sub-report?
Sub-reports are inserted into a main report. Just like a main report, you also pass parameters and queries to it. Think of a sub-report as an extension to your main report, but it contains a different data set. For instance, you could create a report of customers and then use a sub-report to display a list of orders for each customer.

 

66) What are RDL files?
RDL files are like the “language” for SSRS servers. However, RDL files are created in XML, so really the “language” of SSRS servers is XML. RDL files contain the queries and layout format for your reports.

 

67) What is a data set?
Data sets are the components that contain your records. You can have a blank data set, a data set with one record, or a data set with millions of records (although millions of records will probably cause performance issues for your users). You can view a data set like a customized table. The data set has the columns and rows like a table, but you determine the columns and number of rows using your SQL statements.

 

68) What is a data source?
A data source is the database and tables where your data set comes from. You must define the data source when you create your database connection. Every data set needs a source from which to pull the data. Your reporting server can be SQL Server 2000, 2005, 2008 and 2012.

 

69) What servers can be used with SSRS?
While most companies use SQL Server with SSRS, you can also integrate other database servers with your SSRS reports. SSRS is compatible with Oracle, ODBC and OLEDB connections, Hyperion, Teradata and flat XML files that contain data.

 

70) What is mixed mode database security?
When you install SQL Server, you have the option to allow SQL Server to integrate with Windows or require users to have a separate SQL Server user name and password. While Windows integration is convenient, it’s not considered the most secure of the two security options. Instead, it’s better to require a separate SQL Server user name and password when logging in to the database server. Your reports will need their own user name and password to run reports from SSRS.

 

71) Can SSRS reports cache results?
Caching reports makes it much faster for users to access and view data. If you have common data that doesn’t change often, it’s best to cache results. SSRS lets you cache reports on your reporting server. This means that it reduces the load on the SQL Server and your users can quickly access data without querying the server several times.

 

72) What formats can SSRS export or render to?
SSRS is compatible with several file formats. When the user runs the report, the default format prints to the web browser. You can also save or export to HTML, Excel, CSV, Image, PDF and XML formats. The SSRS reporting software has buttons at the top of each report that the user can use to export these files.

 

73) How do you deploy a report to a reporting server?
The SSRS reporting software includes tools to deploy directly to the SQL Server reporting server. After you’ve configured your software with the proper SQL Server, user name and password, you just need to right-click the report you want to deploy and click “Deploy.” Make sure you test the report after you deploy it to ensure there are no bugs and that the data returned is correct.

 

74) How do you edit a report?

Open SQL Server Management Studio and the reporting project. Expand the node that contains your reports. Right-click the report and click “Edit.” You can also save your reporting file from this view.
