Sorting data in SSRS (SQL Server Reporting Services) is a crucial aspect of creating effective and meaningful reports. When presenting data, it often makes sense to sort it based on specific column values to enhance readability and usability. In this article, we will explore how to sort a table in SSRS based on a particular column value, providing you with step-by-step guidance and additional insights.
Understanding the Problem
Sorting data allows users to quickly find the information they need within a report. By default, SSRS does not automatically sort tables unless specified. If you are working with a dataset in SSRS and want to sort it according to specific column values, you need to implement sorting techniques effectively.
Scenario Example: Sorting Employee Data
Consider a scenario where you have a table listing employees along with their salaries and hire dates. Your goal is to sort this table by the Salary column in descending order to identify the highest-paid employees quickly.
Original Code
Here is a simplified version of how the original SQL query might look:
SELECT EmployeeID, EmployeeName, Salary, HireDate
FROM Employees
This code retrieves employee details, but it does not apply any sorting. The next step is to sort this data effectively in SSRS.
Steps to Sort a Table in SSRS
Step 1: Create the Report
First, create a new report in SSRS or open an existing report where you want to apply the sorting.
Step 2: Add the Data Source
Make sure your dataset is connected to the correct data source that retrieves the employee information.
Step 3: Insert a Table
Drag and drop a table from the toolbox onto the report designer. Bind the dataset to this table.
Step 4: Add Data Fields
Add the fields EmployeeID, EmployeeName, Salary, and HireDate to the table cells.
Step 5: Implement Sorting
To sort the table based on a specific column:
- Click on the table.
- In the Row Groups pane, right-click on the row group you want to sort (usually the default group).
- Select Group Properties.
- In the Sorting tab, click the Add button.
- From the drop-down list, select the field you want to sort by (in this case,
Salary). - Choose the sort order (Ascending or Descending). For our example, you would select Descending.
- Click OK to apply the changes.
Step 6: Preview the Report
Now, run the report to see the changes. The table should display the employees sorted by their salary in descending order.
Additional Insights and Considerations
-
Multi-Level Sorting: SSRS allows you to sort by multiple fields. For instance, if two employees have the same salary, you can add a secondary sort by
HireDateto order them chronologically. -
Sorting Grouped Data: If your table has grouped data, sorting can also be applied to group headers. This helps when dealing with hierarchical data.
-
Dynamic Sorting: If you need dynamic sorting where users can select the column to sort by at runtime, consider using parameters. You can create parameters in your report for users to choose their sort preference, and then use expressions in your sorting options.
Conclusion
Sorting tables in SSRS based on column values is a straightforward yet essential task that enhances the presentation of your data. By following the steps outlined in this article, you can effectively sort any table within your reports, improving both usability and readability. Always keep in mind that properly sorted data can significantly impact the decision-making process for stakeholders.

By implementing these sorting techniques, you'll be well on your way to creating more insightful and user-friendly SSRS reports. Happy reporting!
