Q: What is SSRS?
Ans:
Users can generate, manage, and deliver a variety of reports using the server-based reporting technology known as SSRS, or SQL Server Reporting Services. It belongs to Microsoft's SQL Server suite of products.
Q: What is a data source in SSRS?
Ans:
The connection details to the underlying data that the report uses are defined by a data source in SSRS. It could be a SharePoint list, an Oracle database, a SQL Server database, or one of the other supported data sources.
Q: What is a dataset in SSRS?
Ans:
A named query that extracts data from a given data source is referred to as a dataset in SSRS. It serves as the information source for the tablix (table, matrix, or chart) in the report.
Q: What are the key components of SSRS?
Ans:
The following are the main SSRS components:
- Report Server: Primary engine in which is responsible for rendering, processing, and distributing reports.
- Report Manager: An web-based tool for controlling security, data sources, and reporting.
- Report Builder: A tool for creating and designing reports on a desktop.
- An integrated development environment (IDE) within Visual Studio called Report Designer is used to create and modify reports.

Q: What is a tablix in SSRS?
Ans:
In SSRS, a tablix is a data region that can show data as a table, a matrix (pivot table), or both simultaneously. It enables versatile data management and presentation.
Q: How to deploy an SSRS report?
Ans:
The Report Manager or the Report Designer are two tools that users can use to deploy SSRS reports. Users can upload the report file (.rdl) and choose the target location in Report Manager. Right-click the report project in Report Designer and choose "Deploy".
Q: How to add parameters to an SSRS report?
Ans:
Using the Report Data pane in Report Designer, we can add parameters to an SSRS report. Right-click the "Parameters" folder and choose "Add Parameter." Define the parameters' attributes, including their name, data type, and a list of possible values.
Q: What are expressions in SSRS?
Ans:
In SSRS, expressions are utilized to dynamically calculate or display values at runtime. They can be applied to report parameters, fields, filters, and visibility settings. Expressions are written in a language similar to Visual Basic called "Expressions".
Q: How to add interactivity to an SSRS report?
Ans:
Drill-through actions, document maps, and interactive sorting are a few examples of features that can be used to make an SSRS report more interactive. Users may access related reports, switch between tiers of reports, and dynamically sort data due to these functionalities.
Q: How to schedule report execution in SSRS?
Ans:
Report Manager or SQL Server Agent can be used to schedule report execution in SSRS. Set up a subscription by going to the report properties in Report Manager. Create a new job in SQL Server Agent and select the "Reporting Services" task to define the report and schedule.
Q: What are report snapshots in SSRS?
Ans:
In SSRS, report snapshots are read-only copies of reports that are accessible at a certain time. Even if the underlying data has changed, they let users to view reports as they were at the time of snapshot creation.
Q: What is caching in SSRS?
Ans:
The rendered output of a report can be stored in memory or on disk because of the caching in SSRS. When the report is retrieved frequently, this decreases processing time and network traffic, improving performance. Configuring caching options at the report or data source level is possible.
Q: What are the different rendering formats supported by SSRS?
Ans:
The rendering formats that SSRS supports include PDF, Excel, Word, CSV, HTML, XML, and Image. When viewing or exporting a report, users have the option to select the appropriate format.
Q: How to add custom code to an SSRS report?
Ans:
Using the Code tab in the Report Properties dialogue, users may add custom code to an SSRS report. This enables it to use the Visual Basic language to create and call unique functions or subroutines.
Q: How to secure an SSRS report?
Ans:
An SSRS report can be secured via Windows Authentication, Forms Authentication, or other authentication techniques, or by defining security settings in the Report Manager. Access can be restricted at the item, report, and folder levels.
