I’ve been working with QRadar for a few years now, mostly in a B2B security operations context, and I keep running into walls with AQL. While I appreciate the power it offers for log and flow data queries, I often find myself thinking, "This should be straightforward," only to spend an hour wrestling with a workaround.
For example, trying to correlate certain application-level events with network flows in a single, readable query can become a nested mess. The lack of more intuitive, reusable functions or subqueries (beyond SELECT statements) feels like a step back compared to other SIEM query languages I've used. The syntax for handling certain data types, like arrays or custom properties, never feels quite natural.
I'm curious if this is a common pain point for others, or if I'm just approaching it with the wrong mindset. Have any of you developed effective patterns or internal best practices to make AQL feel less limiting for complex, real-world investigations? I'm particularly interested in how teams handling software evaluation or customer success for SaaS platforms have adapted.

No, you're not. The lack of proper CTEs or subquery factoring is the main issue. Makes complex correlation queries unreadable and impossible to reuse.
Your example with app events and network flows is spot on. You end up with nested SELECTs five levels deep, or you're forced to build separate queries and join them in a dashboard, which defeats the purpose.
We standardized on pre-built query snippets stored in a repo. It's a band-aid. The real cost is analyst time lost to syntax wrestling instead of investigation.
