Free SQL Help for Devs, DBAs, and the Curious

SQL Server Reporting Services (SSRS) is a server-based report generating software system provided by Microsoft. It is used to prepare and deliver a variety of interactive and printed reports. With SSRS, you can create interactive, tabular, graphical, or free-form reports from relational, multidimensional, or XML-based data sources. Drillthrough reports are a key feature of SSRS, allowing users to view additional report data that is related to the current dataset. This blog post will explore how to implement drillthrough navigation between reports using technologies from SQL Server 2019, MySQL 8.0, DB2 11.5, Azure SQL, and Azure Synapse.

Creating a drillthrough report involves two main reports: the main report and the drillthrough report. The main report displays the overall data summary, while the drillthrough report displays related details when a user clicks a data point in the main report. This feature is particularly useful when dealing with large datasets, as it allows users to focus on important data in a more detailed report.

Here's an example of how to create a drillthrough report using SQL Server 2019. The main report could be a list of customers, and the drillthrough report could display all orders for a selected customer. To link these reports, you need to add a textbox with an action that navigates to the drillthrough report. In the action properties, you set the navigation to the drillthrough report and pass the customer ID as a parameter.

SELECT c.CustomerID, c.CompanyName
FROM Customers c

In the drillthrough report, you use this customer ID to filter the data. The SQL statement for the drillthrough report could look like this:

SELECT o.OrderID, o.OrderDate, o.Total
FROM Orders o
WHERE o.CustomerID = @CustomerID

This approach can be used with other relational databases like MySQL 8.0 and DB2 11.5 as well. However, when using Azure SQL or Azure Synapse, you need to take into consideration the specific features and limitations of these platforms. For instance, Azure SQL and Azure Synapse use the T-SQL language, which is very similar to SQL Server 2019, but they have specific features for managing and analyzing large datasets in the cloud.

In conclusion, the SSRS drillthrough navigation feature provides a powerful tool for data analysis. It allows users to view detailed data related to specific data points in a summary report. This feature can be implemented using a variety of databases including SQL Server 2019, MySQL 8.0, DB2 11.5, Azure SQL, and Azure Synapse. The key is to understand the specific features and limitations of each platform and to design the reports accordingly.
