Hi Jacob, Thanks very much for your enquiry. Very interesting question. I will comment inline

I have created a feature request for this: https://github.com/jOOQ/jOOQ/issues/5655 You could make that a Field<Object>, which wouldn't be too wrong, because in Java, Void is a subtype of Object. The solution that you've found works as well, but I wonder if there might be a side effect. > 2) Would DSL.function be more appropriate to use instead of DSL.field in > question # 1? I wasn't sure how to pass in my argument using DSL.function. > That would work as well. You used the plain SQL API, which is much more powerful. > 3) In question #1, is there a way to bind the schema name instead of > hardcoding it in the sql? Or is putting it in the sql the best/only way? > The "best" way would be this: DSL.field("{0}.foo({1}, {2}, {3})", schema(name("ext")), val(...), val(...), val(...)); Or, alternatively: DSL.field("{0}({1}, {2}, {3})", name("ext", "foo"), val(...), val(...), val(...)); I.e. you create an actual org.jooq.Schema reference and put that before the dot, or you create a qualified org.jooq.Name and put that before the brackets.
