About this pageAI generated

This page is the fifth post in a Seal Report tutorial series. While automatically retrieving data from multiple tables is powerful, real-world reporting scenarios often require custom SQL expressions, user-defined functions, or stored procedures. The article demonstrates how to link SQL expressions with other tables, combining Seal Report's automatic joins and filters with custom SQL logic. Prerequisites include an AdventureWorks2025 database instance and familiarity with configuring data sources in Seal Report. The goal is to rewrite a previous report using a different approach: retrieving data from Person.Person and HumanResources schema in a single SQL expression, applying custom joins between tables, and maintaining dynamic filters.
