For example, all types other than String are exact-match only. For example: create procedure uspSum ( @param1 int, @param2 int, @result int output ) as begin set @result = @param1 + @param2 return @result end Declare @r int exec uspSum 5, 7, @r output select @r you have to use either R2DBC or Hibernate reactive. session, class: Author The problem is that you are passing String. The properties you do need at this stage are these three: In the former post Integrating Vertx with Spring framework and the further post, we have integrated Hibernate Reactive with Spring IOC container, but in those the posts, the web handling is done by Vertx Web.

My goal is to get a stream or list of examples and then run updates on each one and persist those updates, then run another function that does some other stuff - I know this other function works and it takes in an id parameter and returns a Uni<Void>. Welcome to the Hibernate Native SQL Query example tutorial. For third-party dialects, the expected value is the fully-qualified class name, for example com. @Id @GeneratedValue(strategy = GenerationType. MetadataImplementor) org. The semantics of operations on this interface are identical to the semantics of the similarly-named operations of Session, except that the operations are performed asynchronously, returning a Uni without blocking the calling thread. Database access will be made using the Hibernate Reactive APIs and a Reactive Vert. With Panache: public Uni<Result> getAbc() { String nativeQuery = ; return Panache. If you want to use Hibernate/JPA JPQL like query in your project, consider Hibernate Reactive. reactive:smallrye-mutiny-vertx-pg-client brings the driver implementation on the classpath. time. reactive. hibernate. Show more. Navigating the issues of the project, I found an answer from @jiangtj and managed to elaborate the following piece of code: In the Spring integration post, we use Spring to assemble the resources and start up the application. But this happens only when you use await() or similar compositions where vertx can actually tell that it is being blocked, not when other blocking or expensive operations are run (like blocking IO I tried to use oracle as db in my hibernate reactive example, but I can not make the connection working well against localhost.
