DB2 "With UR" Spring JPA Data

Question

I am using the Spring Data Repository interface to retrieve data from DB2 (z / OS). I have several methods that rely on method signs and that they rely on explicit @Query.

How to create a SQL query with a WITH WITH clause? I added @Transactional (isol = Isolation.READ_UNCOMMITTED) in the line above the @Query annotation, as well as over these two methods, but it doesn't seem to add the sentence to the generated SQL.

thank
