In this post, i'll outline key principles guiding my team's approach—domain driven design (ddd), database first design, and enumerations over booleans—before demonstrating how f# can persist and materialize discriminated unions in oltp systems using dapper.fsharp. As part of sql’s data manipulation language (dml), union is a must know for anyone working with relational databases. in this blog, we’ll explore the union operator in depth, covering its syntax, use cases, and practical applications with clear examples. The union clause simplifies querying across multiple tables, allowing developers to merge data effectively. in this article, we will discuss the syntax, examples, and use cases of the union clause, along with explanations and outputs for better understanding. Try writing your own union queries, experiment with different tables and conditions. before you know it, you'll be unioning like a pro! i hope this tutorial has helped demystify the sql union operator for you.
