Q: What is SSRS?
- SSRS or SQL
Server Reporting Service is a server-based report generation software
systems from Microsoft and is part of Microsoft BI.
- It is used to
prepare and deliver rich variety of reports (Tabular / Matrix / Graphical/Interactive) from
various data sources with rich data visualization (Charts, Maps, spark lines)
- It is
administered through a web based interface.
- Various
rendering formats in SSRS include Excel, PDF, word, MHTML etc
Q: Explain SSRS
Architecture?
Reporting
services architecture comprises of integrated components.
Q: Explain Reporting Life
Cycle?
Reporting
Services has mainly three phases:
- Development
of Reports (Developer) – First of all a report needs to be design which is
primarily done by report developer
- Management
of Reports (DBA) – Once the Report is being developed, DBA need to ensure
- 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 are executed on
scheduled timings
- 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.
- Report Designer is used to create the reports.
- Report Sever is used to execute and distribute
reports.
- 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 from 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: What are different
types of roles provided by SSRS?

properties between the Report Server to the repository database.
- RSKeyMgmt.exe: Management of encryption keys via
command-line
- RS.exe: Utility used for deploying the
report on report server
Q: What are the three
different parts of RDL file explain them?
In visual studio RDL
files has three parts.
- Data: It contains the dataset on which
we write the query. Data set is connected with data source.
- Design: In design you can design report.
Can create tables and matrix reports. Drag columns values from source.
- Preview: to check the preview after the
report run.
Q: Which language rdl
files made of?
RDL files are written in
XML.
Q: Can you edit the .rdl
code associated with a linked report?
No, because a linked
report has no .rdl code of its own. It refers to the .rdl code of the base
report
Q: What is report rendering?
Exporting a report data
with design o different type of file types is knows as Report rending. SQL
Server Reporting Services supports multiple rendering extensions like Word,
Excel, CSV, PDF, HTML etc.
Q: What are the different
types of data sources in SSRS?
SSRS use different data
source. Some of them are listed below.
- Microsoft SQL Server
- OLEDB
- Oracle
- ODBC
- SQL Server Analysis Service
- Report Server Model
- SAP Net weaver BI
- Hyperion
- Teradata
- XML
Q: What is the name of
reporting services configuration file and what’s it’s used for?
·
The SSRS
configuration file is RsReportServer.config.
·
It
stores settings that are used by Report Manager, the Report Server Web service,
and background processing.
Q: What are Advantages of
SSRS or why we should use SSRS?
The SQL Server Reporting Services or SSRS has some Advantages
- It is faster,
cheaper and easy to learn
- Efficient access
to various data sources
- Role-based
security exists and can be applied to reports and folders as well
- Uses its own
web-service and don’t depend on IIS
- Once parameters
are defined, the UI for these parameters is automatically generated
- Supports various
delivery extensions like Excel, Pdf, MHTML etc.
- Subscription
based reports are automatically sent by mail to the users
Q: What are the
limitations/drawbacks of SSRS 2008 R2?
The SSRS 2008 R2 has some limitations. Some limitations are given below:
- There is no
direct print button. In order to print need to export excel, PDF or others
format
- It is very hard
to debug expression or custom code
- It’s does not
use page number or total pages in report body
- Don’t support
rounding rectangle
- There is no way
to pass values from sub-reports to main report
- It is not
possible to insert a sub-report into the page header or page footer
- Page header creates
extra spaces in the next pages
- Issues in exported
excel files like merged columns, extra columns, loss of data etc
Q: What are the different
rendering extensions of SSRS?
SSRS allow many ways of rendering the reports:
- HTML (MHTML)
- Excel
- Acrobat
- Tiff (image)
- XML
- CSV
Q: What is a report snapshot?
Snapshot means an instance of a report for future reference which means a copy
of report will be saved on a report server for future reference.
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: When to Use Null Data
driven Subscription?
The null delivery provider used for preloading the cache. 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.
You
cannot specify multiple delivery extensions within a single subscription
Q: How to fine-tune Reports?
To tune-up the Reporting Services,
follow the below mentioned ways: -
1. Ensure that the
data retrieval is optimized
2. During data
retrieval, we can only bring required data, avoid unnecessary calculations and
temp tables, using NOLOCKs to avoid locking issues
3. Ensure that the
report is delivering only required images, minimize the complexity of the
calculations and minimize the data points in a graph or chart
4. Include only absolutely
needed groupings and sorting in the report
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. But it can query the data existing in an excel file. 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 Breaks and Physical Page Breaks 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.
·
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: Name few Endpoints exposed by SSRS 2012?
- Management Endpoints
- Execution Endpoint
- SharePoint Proxy Endpoints
Q: What are the new
features are introduced in SQL Server 2012 reporting services?

alerts are a data-driven alerting solution that informs you about changes
in report data that are of interest to you, and at a relevant time
- New rendering extensions supports
MS Office 2010
- SSRS 2012 is fully integrated with
SharePoint
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 Tabular Report in SSRS?
Tabular report is the simplest of the SSRS Report. It lets you just
simply display the data using table.
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 is Query parameter in SSRS?
Query parameter is mentioned in the query of the data-source that is to
be included in 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
cannot begin with numeral. For clarity, we use only letters.
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 charts and various other options. 3D charts are also available in
reporting services.
Q.
What is RowNumber function?
RowNumber returns a sequential number to every row within the specified
scope.
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 will they be applied in Cached
Report instance?
Filters are applied when a report is rendered, Filters will not create a
new cached instance on the Report Server.
Q:
What are data regions?
Data regions are report items that display repeated rows of summarized
information from data-sets.
Q:
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.
Q:
Describe different Processing Modes offered by SSRS?
- Local Processing
Mode: Processes
reports in the client application.
- Remote
Processing Mode: Renders server
reports that are processed on a SQL Server Reporting Services report
server.
Q: What is ReportServer
and ReportServerTempDB ?
·
Reporting
Services uses two SQL Server databases for storage by default.
·
ReportServer
is a main database, which store all internal configuration and report meta-data
·
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
- RSReportServer.config stores configuration settings for
feature areas of the Report Server service: ReportManager, the Report
Server Web service, and background processing.
- RSSrvPolicy.config stores code access security
policies for the server extensions.
- RSMgrPolicy.config stores code access security
policies for Report Manager
- ReportingServicesService.exe.config stores configuration settings
that specify the trace levels and logging options for the Report Server
service.
- RSReportDesigner.config contains settings for Report
Designer and this file is located in the..\Program Files\Visual Studio
9.0\Common7\IDE\PrivateAssemblies
- 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: Can we run Reporting Services with SQL Server express
edition, which is a free version of SQL Server?
Yes we can. SQL Server Express Edition with Advanced Services support Reporting
Services. These is the free version.

deploy the report through Solution explorer by providing the report server
URL in project properties at Target Server URL. As our choice this will
deploy entire project or single report as.
- Using Report Server: We can directly go to the report
server and deploy the report by browsing the report from the disk location
of server.
- Creating the Utility: SQL server provides the
facilities to Create a customize utility to deploy the report.
Q: What are the new

Q: How to backup SQL
Server Reporting Services?
There are mainly three things, which should be backed up as part of reporting
services backup
- Report Server Databases, which can be backed up by SQL
server backup and restore method.
- SQL Server Reporting Services
Configuration, SQL Server
Reporting Services Configuration is saved in config files, which can be
copied as part of backup.
- Encryption
Keys backup, use SQL Server
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 the different types of reports in SSRS?
The types of reports in SSRS are given
below:
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 drill-through reports, linked reports, and sub-reports, 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: 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:
- Report history: By creating a series of report
snapshots, you can build a history of a report that shows how data changes
over time.
- 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.
- 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 Click-through Reports?
A click-through 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
click-through report is opened. These field settings cannot be changed in the
report authoring tools. Click-through reports are auto-generated. 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 Drill-down Reports?
Drill-down reports initially hide complexity and enable the user to toggle
conditionally hidden report items to control how much detail data they want to
see. Drill-down reports must retrieve all possible data that can be shown in
the report.
For reports with large amounts of data, consider drill-through reports instead.
Q: What
are Drill-through Reports?
Drill-through reports are standard reports that are accessed through a
hyperlink on a text box in the original report. Drill-through 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 drill-through links to reports that display greater details based
on the aggregate in the main report. Drill-through reports can be filtered by
parameters, but they do not have to be. Drillthrough reports differ from
sub-reports in that the report does not display within the original report, but
opens separately. They differ from click-through 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 drill-down 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).
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: 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 once 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:
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.
