I suspect this is about the SQL Server SOUNDEX()
function? There's currently no native support for this function in jOOQ 3.2, although support is on the roadmap with #2969. As always with unsupported stuff in jOOQ, you can resort to plain SQL, creating a custom Field like this:
Field<String> fn = DSL.field("SOUNDEX({0})", String.class, argument);
See the DSL.field()
Javadoc for details.
