Hi Alessandro, Thanks a lot for your report. This is a funny edge case bug, which I've created here: https://github.com/jOOQ/jOOQ/issues/16662
The reason for this practice is documented in this earlier bug here: https://github.com/jOOQ/jOOQ/issues/10007 javac has a size limit for string literals, so we split the literal into several sub literals. We also escape newlines (e.g. \n) and other things, but unfortunately, that is being done before the splitting, so it is (rarely) possible for the splitting to happen exactly where the escaped newline is located, thus separating "\" from "n", which is obviously wrong. I'll fix #16662 right away. As a workaround, you can: - Insert arbitrary characters (e.g. whitespace) into your view source code to avoid the issue for this particular view - Post-process generated code to fix this issue - Turn off the generation of view source code: https://www.jooq.org/doc/latest/manual/code-generation/codegen-advanced/codegen-config-generate/codegen-generate-sources/ I hope this helps, Lukas On Tuesday, May 7, 2024 at 12:26:29 PM UTC+2 Alessandro Brambilla wrote: > Environment: > -JDK21 (but even 17 is KO) > - Oracle DB 19c > - Oracle driver ojdbc11 (23.3.0.23.09) but it happens also with ojdbc10 as > well > - Jooq 3.17 (Enterprise) > > Hi, > we have an issue with model generator (by "org.jooq.codegen.GenerationTool" > direct call) when generating code for an Oracle View.
