Example of dynamic table
Hello community!
I want to try the feature of dynamic table but do not find examples in the official doc.
Is this part missing?

I think the Getting Started page[1] can answer your question.

I’ve got the concept figured out, but don’t know how.
For example, I have 2 kafka tables `a` and `b`, and want to execute a continuous query like ’select a.f1,b.f1 from a left join b on a .f0 = b.f0’. How to write the sql to tell flink that it’s a continuous query?

What do your mean "try the feature of dynamic table", do you want to know the concept of dynamic table[1] or User-defined Sources & Sinks[2] with dynamic table?
