SQL transformation

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

jOOQ supports a few built in SQL transformations, which can be enabled through a variety of settings. These transformations will produce transformed SQL output regardless if the input was created using the DSL API, or the parser.
