SQL Server Reporting Services (SSRS)

SQL Server Reporting Services

SQL Server Reporting Services (SSRS) is a server-based reporting platform that lets teams design, generate, and deliver paginated or interactive reports from SQL Server and other data sources.

What Is SQL Server Reporting Services?

SQL Server Reporting Services (SSRS) is Microsoft’s enterprise reporting solution for building, hosting, and distributing richly formatted reports. It runs on-prem or in a VM, exposes a web portal, and outputs to PDF, Excel, Word, or HTML.

How Does SSRS Work?

Report definitions written in Report Definition Language (RDL) specify queries, layout, and parameters. The SSRS Report Server processes the RDL, connects to data sources, renders the result through selected renderers, and serves the output to browsers, email subscriptions, or APIs.

What Are the Main SSRS Components?

Key elements include Report Server (web service & processing engine), Web Portal, Report Builder and Visual Studio extensions for design, SQL Server database for catalog, and the RDL XML files that describe each report.

Why Choose SSRS Instead of Power BI?

SSRS excels at pixel-perfect, highly formatted, printable documents, long tables, and batch delivery. Power BI is optimized for interactive analytics. Regulatory, invoice, or operational reports often require the fixed layouts SSRS provides.

How Do I Create a Simple SSRS Report?

Open Visual Studio with SQL Server Data Tools, start a Report Server Project, add a Shared Data Source, create a Data Set with your query, drag a table or matrix to the design surface, map fields, add parameters if needed, preview, then deploy.

How Do I Deploy Reports to the SSRS Server?

Set the TargetServerURL in project properties, right-click the project, and choose Deploy. Alternatively, upload the .rdl file through the Web Portal or automate with rs.exe script.

How Do Parameters Improve Reports?

Parameters filter data, change formatting, and drive cascading selections. Define a parameter, set available values, reference it in your dataset query with @Param syntax, and pass default values from subscriptions or URLs.

Can I Use Galaxy With SSRS Development?

Yes. Galaxy’s desktop SQL editor accelerates dataset query writing for SSRS. You can prototype T-SQL with AI Copilot, store endorsed queries in Collections, then paste performance-tuned SQL into your RDL—eliminating guesswork and Slack paste-bombs.

What Are Common SSRS Performance Best Practices?

Use stored procedures or views for datasets, keep result sets narrow, avoid complex expressions in large tables, enable caching, and schedule resource-heavy reports during off-peak hours.

How Do I Automate Report Delivery?

Create a Standard or Data-Driven Subscription, select output format, destination (Email, File Share, Power BI), set schedule, and map parameter values. SSRS handles rendering and distribution without manual intervention.

What Security Options Does SSRS Provide?

SSRS supports Windows Authentication, role-based item-level security, custom extensions, and encryption of catalog data. Use separate service accounts, SSL, and least privilege principles for hardened deployments.
