Describe the bug
I build some tables in risingwave, and import them as foreign tables to postgres via FDW (postgres_fdw plugin), then I query postgres foreign tables using SpringData JPA (which uses Hibernate inside). I execute one same query for 10 times, for the first 9 times everything woks fine, but at the last time, risingwave throws error as shown in
Error messge/logbelow. I inspected all this 10 times query SQL statement genereated by hibernate and I found they are same. I dumped risingwave's query log and I found that postgres_fdw deliver a wrong SQL to risingwave at the last time which is:I show the detailes in
Error message/logandTo Reproduce blockbelow.Error message/log
To Reproduce
@Data @Entity @Table(name = "tb_cjg_1") public class Cjg {
@Id private Integer id;
private LocalDate tradingDate; private Integer volume; }
// CjgRepository.java import java.util.Optional; import org.springframework.data.jpa.repository.JpaRepository;
public interface CjgRepository extends JpaRepository<Cjg, Integer> {
Optional findById(Integer id);
}
// App.java import jakarta.annotation.Resource; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; import play.repository.pg.CjgRepository;
@SpringBootApplication public class App {
@Resource private CjgRepository cjgRepository;
public static void main(String[] args) { SpringApplication.run(App.class, args); }
@Bean public CommandLineRunner runOffline() { return (args) -> { for (int i = 0; i < 10; ++i) { System.out.println(cjgRepository.findById(1)); } System.exit(0); }; } }
