带有 Hibernate 的存储过程在嵌入式 h2 数据库中失败

Question

Im saving data to myRepository1 and to be able to see the savings via the materialized view, i need to refresh it.

      myRepository1.save(myObject);
      myRepository2.refreshView();

myRepository2 has:

        @Modifying
        @Query(value = "BEGIN my_refresh_view(); END;", nativeQuery = true)
        void refreshView();

Where my_refresh_view is a simple stored procedure. This works fine in the real world (Oracle DB) - however, when i run my integration tests for the code above using an embedded h2 database, i get:

BEGIN my_refresh_view(); END; [42000-200]
org.springframework.dao.InvalidDataAccessResourceUsageException could not prepare statement;

    at org.springframework.dao.support.ChainedPersistenceExceptionTranslator.translateExceptionIfPossible(ChainedPersistenceExceptionTranslator.java:61)

Looks like the stored procedure and h2 dont match well together.

Any ideas how to make it work, or maybe there are workarounds?

Answer 1

Hibernate JPA (at least 5.0.0 and below) does not support stored procedures for H2Dialect.H2Dialect inherits Dialect.getCallableStatementSupport() which returns StandardCallableStatementSupport.NO_REF_CURSOR_INSTANCE. The standard callable statement support does not properly handle the H2 "out" parameter which is a Java return value and not a statement parameter check details here
