SSRS INTERVIEW QUESTIONS
Q:
What is SSRS?
Ø SSRS or SQL Server Reporting
Service is a server-based report generation software systems from Microsoft and
is part of Microsoft BI.
Ø It is used for preparing and
delivering interactive and variety of reports.
Ø It is administered through an
web based interface.
Ø Reporting services utilizes a
web service interface for supporting and developing of customized reporting
applications.
Ø SSRS lets you create very
rich reports (Tabular/Graphical/Interactive) from various datasources with rich
data visualization (Charts, Maps, sparklines)
Ø SSRS allows are reports to be
exported in various formats (Excel, PDF, word etc)
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?
Reporting Services has three mainly three phases
Reporting Services has three mainly three phases
Ø Development of Reports (Developer) –
First of all a report needs to be design which is primarily done by report
developer
Ø Management of Reports (DBA) – Once the
Report is being developed, DBA need to ensure
o
Security – Only
authorized user should access the report
o
Execution – How
the report will be executed to optimize data sources performance
o
Scheduling of reports
– so that report are executed on scheduled timings
Ø Report Delivery (DBA + Developer) – Once
the report is being developed and executed now the report should be reached to
final recipients (business users) who are going to understand / analyze report
data. if any changes, we again go back to development stage.
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.

Ø Report Designer is used
to create the reports.
Ø Report Sever is used
to execute and distribute reports.
Ø 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:
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:
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.

of connection properties between the Report Server to the repository database.
Ø RSKeyMgmt.exe: Management
of encryption keys via command-line
Ø RS.exe: Utility
used for deploying the report on report server
Q:
Describe different Processing Modes offered by SSRS?
Ø Local Processing Mode: Processes reports in the
client application.
Ø Remote Processing Mode: Renders server reports that
are processed on a SQL Server Reporting Services report server.
Q: What is
ReportServer and ReportServerTempDB ?
Ø Reporting Services uses two
SQL Server databases for storage by default, the databases are
named ReportServer and ReportServerTempdb.
Ø ReportServer is a main
database, which store all internal configuration and report meta data
whereas ReportServerTempdb is used to store temporary data, session
information, and cached reports.
Q: What is encryption
key?
Encryption
keys are used by the report server so that items such as connection strings are
maintained securely. These keys are required in case you want to perform
restoration of report server databases
Q:
How to backup encryption key ?
Encryption
Keys backup, use SQL Server Reporting Services Configuration tool to backup
symmetric keys.
Q:
What are the key configuration files for SQL Server Reporting Services ?
Mostly
all Configuration files located at Install Directory:
\Microsoft
SQL Server\\Reporting Services\ReportServer and ReportManager
Ø RSReportServer.config stores configuration
settings for feature areas of the Report Server service: ReportManager, the
Report Server Web service, and background processing.
Ø RSSrvPolicy.config stores code access
security policies for the server extensions.
Ø RSMgrPolicy.config stores code access
security policies for Report Manager
Ø ReportingServicesService.exe.config stores configuration
settings that specify the trace levels and logging options for the Report
Server service.
Ø RSReportDesigner.config contains settings for
Report Designer and this file is located in the..\Program Files\Visual Studio
9.0\Common7\IDE\PrivateAssemblies
Ø RSPreviewPolicy.config stores server
extensions used during report preview and this file is located
in ..\Program Files \Microsoft SQL Server\100\Tools \ReportDesigner
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: In
which SQL Server version report builder introduced?
Report
builder introduced in SQL Server 2005. While creating or deploying report model
project on report server you can get error or it might not get created. For
this you need to check whether the service pack 22 is installed or not.
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 are the three different part of RDL file explain them?
In visual studio RDL files has three parts.
Ø
Data: It contains the
dataset on which we write the query. Data set is connected with data source.
Ø
Design: In design you
can design report. Can create tables and matrix reports. Drag columns values
from source.
Ø
Preview: to check the
preview after the report run.
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.

Reporting Services Configuration tool to backup symmetric keys.
Q: What is the web service
used for reporting services?
Reporting Service Web Service used in SSRS. By
accessing this web service you can access all report server component and also
get the report deployed on report server.
Q: What is a cache in SSRS?
Report server can lay up a copy of processed
report in a memory and return the copy when a user opens the report. This
server memory is known as cache and the process is called caching.
Q: Can you always create a cache of a report?
No, you can create a cache of a report only
when certain requirements, such as having credentials stored in the Report
Server, are met.
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 report snapshot?
Snapshot means a instance of a report for future reference, that
means a copy of report (data is freezed) will be saved on a report server for
future reference.
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 to fine-tune 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 no lock, 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:
User wants only to display only PDF as export option in report Manager. How to
achieve this?
You
need to edit RsReportServer.Config file to limit the exporting extensions to
only PDF.
You
can find the file under;
%Program
Files%\Microsoft SQL Server\MSRS10.\Reporting Services\ReportServer\
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:
Difference between Logical Page and 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.

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: What are the Types of SSRS?
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: What are the Types of SSRS?
The
types of SSRS are given below:
Ø Parameterized reports
Ø Linked reports
Ø Snapshot reports
Ø Cached reports
Ø Ad hoc reports
Ø Clickthrough reports
Ø Drilldown reports
Ø Drillthrough reports
Ø Subreports
Q:
What is Parameterized Reports in SSRS ?
A
parameterized report uses input values to complete report or data processing.
With a parameterized report, you can vary the output of a report based on
values that are set when the report runs. Parameterized reports are frequently
used for drillthrough reports, linked reports, and subreports, connecting and
filtering reports with related data.
Q:
What is Linked Report?
A
linked report is a report server item that provides an access point to an
existing report. Conceptually, it is similar to a program shortcut that you use
to run a program or open a file.
A
linked report is derived from an existing report and retains the original's
report definition. A linked report always inherits report layout and data
source properties of the original report. All other properties and settings can
be different from those of the original report, including security, parameters,
location, subscriptions, and schedules.
You
can create a linked report on the report server when you want to create
additional versions of an existing report. For example, you could use a single
regional sales report to create region-specific reports for all of your sales
territories.
Although
linked reports are typically based on parameterized reports, a parameterized
report is not required. You can create linked reports whenever you want to
deploy an existing report with different settings
Q:
Whar are Clickthrough Reports?
A clickthrough report
is a report that displays related data from a report model when you click the
interactive data contained within your model-based report. These reports are
generated by the report server based on the information contained within the
report model. The person who created the model determines which fields are
interactive and which fields are returned when a clickthrough report is opened.
These field settings cannot be changed in the report authoring tools.
Clickthrough reports are autogenerated. However, you can create an alternative
customized report to the model for interactive data items that is displayed
instead. The custom report is a standard Reporting Services report.
Q:
What are Drilldown Reports?
Drilldown
reports initially hide complexity and enable the user to toggle conditionally
hidden report items to control how much detail data they want to see. Drilldown
reports must retrieve all possible data that can be shown in the report.
For
reports with large amounts of data, consider drillthrough reports instead.
Q:
What is Snapshot Report?
A
report snapshot is a report that contains layout information and query results
that were retrieved at a specific point in time. Unlike on-demand reports,
which get up-to-date query results when you select the report, report snapshots
are processed on a schedule and then saved to a report server. When you select
a report snapshot for viewing, the report server retrieves the stored report
from the report server database and shows the data and layout that were current
for the report at the time the snapshot was created.
Report
snapshots are not saved in a particular rendering format. Instead, report
snapshots are rendered in a final viewing format (such as HTML) only when a
user or an application requests it. Deferred rendering makes a snapshot
portable. The report can be rendered in the correct format for the requesting
device or Web browser.
Report
snapshots serve three purposes:
Ø Report history. By creating a
series of report snapshots, you can build a history of a report that shows how
data changes over time.
Ø Consistency. Use report
snapshots when you want to provide consistent results for multiple users who
must work with identical sets of data. With volatile data, an on-demand report
can produce different results from one minute to the next. A report snapshot,
by contrast, allows you to make valid comparisons against other reports or
analytical tools that contain data from the same point in time.
Ø Performance. By scheduling
large reports to run during off-peak hours, you can reduce processing impact on
the report server during core business hours.
Q:
What is Cached Report?
A
cached report is a saved copy of a processed report. Cached reports are used to
improve performance by reducing the number of processing requests to the report
processor and by reducing the time required to retrieve large reports. They
have a mandatory expiration period, usually in minutes.
Q:
What are Drillthrough Reports?
Drillthrough
reports are standard reports that are accessed through a hyperlink on a text
box in the original report. Drillthrough reports work with a main report and
are the target of a drillthrough action for a report item such as placeholder
text or a chart. The main report displays summary information, for example in a
matrix or chart. Actions defined in the matrix or chart provide drillthrough
links to reports that display greater details based on the aggregate in the
main report. Drillthrough reports can be filtered by parameters, but they do
not have to be. Drillthrough reports differ from subreports in that the report
does not display within the original report, but opens separately. They differ
from clickthrough reports in that they are not auto generated from the data
source, but are instead custom reports that are saved on the report server.
They differ from drilldown reports in that they retrieve the report data only
for the specified parameters or for the dataset query.
Q:
What is Subreport?
A
subreport is a report that displays another report inside the body of a main
report. Conceptually, a subreport is similar to a frame in a Web page. It is
used to embed a report within a report. Any report can be used as a subreport.
The subreport can use different data sources than the main report. The report
that the subreport displays is stored on a report server, usually in the same
folder as the parent report. You can set up the parent report to pass parameters
to the subreport.
Although
a subreport can be repeated within data regions using a parameter to filter
data in each instance of the subreport, subreports are typically used with a
main report as a briefing book or as a container for a collection of related
reports.
For
reports with many instances of subreports, consider using drillthrough reports
instead.
Q:
What is Data Set in report?
Data set is a set of data which we want to show in report. Data source is the source of data from where we are getting this data (database server name, database name, connection string).
Data set is a set of data which we want to show in report. Data source is the source of data from where we are getting this data (database server name, database name, connection string).
Q: Is
SSRS support other database except MS SQL Server?
Yes.
SSRS can be building based on relational or multidimensional data source like
Oracle, OLEDB. ODBC etc
Q:
What is Query parameter in SSRS?
Query parameters is
mentioned in the query of the datasources that are to be included into the SQL
script’s WHERE clause of the SQL that can accept parameters. Query parameters begin with the
symbol @.The name should not contain spaces and can not begin with numeral. For
clarity, we use only letters.
Q:
What is a matrix in SSRS?
A
matrix is a data region linked to a report set. Matrix allows us to create
crosstab reports with the report variables displaying on rows and columns. It allows
us to drag and drop fields into it.
Q:
What are sub reports and how to create them?
A sub
report is like any other reports which can be called in main report and can be
generate through main report. Parameters can be passed from main report to sub
report and basis of that report can be generated.
Q:
What is the chart in report?
Chart
reports are for graphical representation. You can get pie charts columns harts
and various other options. 3d charts are also available in reporting services.
Q:
How to add the custom code in Report?
To
add the custom codes in report go to report tab on top then properties and
there you will find the options for custom code.
Q: In
case you have filters in your report, when filters will be applied in Cached
Report instance?
Filters

Q: Can
we use data grids 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:
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 Office Writer. 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:
What is report subscription?
Subscriptions
are standing requests to deliver report data to requested recipients. Once the
report is being subscribed and subscriber will get updates from report server
on scheduled interval.
Q:
Can you use a stored procedure to provide data to an SSRS report?
Yes,
you can use a stored procedure. 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.
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.
Q: How
to deploy the Report?
Report
can be deployed in three ways.
Ø Using visual studio: In
visual studio you can directly deploy the report through solution explorer by
providing the report server URL in project properties at Target Server URL.
This will deploy entire project or single report as per you selection.
Ø Using report server: Can
directly go to the report server and deploy the report by browsing the report
from the disk location on server.
Ø Creating the utility: SQL
server provides the utility using that which can be used to create a customize
utility for your report deployment in bulk.
Q:
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.

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.
