Thank you Lukas. Now I understand the primary use case of jOOQ createTable feature.
Typical application has a fixed schema or schema that rarely changes. Also when there is a change, schema changes applied during application start. But my use case is totally different from it. I'm working on a feature where schema of a dataset is detected and corresponding table is created in run-time. Since the schema is generated programatically in runtime, I'm looking for some kind of Java DSL library like jOOQ createTable. Obviously Flyway can be useful here to manage the schema generated by DSL but it doesn't help to generate it. What would you recommend for my use-case? An idea I have is to do some String manipulation on the table statement result generated by jOOQ. Thank you.
