JPA は初めてで、DB2 ストアード・プロシージャーを呼び出そうとしています。ただし、生成されているSQLが間違っていることがわかり、失敗しています。
ストアドプロシージャのセットアップ方法は次のとおりです。
@NamedStoredProcedureQuery(name = "getApplVars", procedureName = "prc_get_all_appl_var", resultClasses = ApplVars.class,
parameters = {@StoredProcedureParameter(mode = ParameterMode.IN, name = "ip_cus_set_c", type = String.class),
@StoredProcedureParameter(mode = ParameterMode.IN, name = "ip_cps_ver_n", type = Integer.class),
@StoredProcedureParameter(mode = ParameterMode.OUT, name = "op_sqlstate", type = String.class),
@StoredProcedureParameter(mode = ParameterMode.OUT, name = "op_sqlcode", type = Integer.class),
@StoredProcedureParameter(mode = ParameterMode.OUT, name = "op_msg", type = String.class)})
ストアド プロシージャを呼び出しているコードは次のとおりです。
EntityManagerFactory emf = Persistence.createEntityManagerFactory("DB1");
EntityManager em = emf.createEntityManager();
StoredProcedureQuery spq = em.createNamedStoredProcedureQuery("getApplVars");
spq.setParameter("ip_cus_set_c","CONS");
spq.setParameter("ip_cps_ver_n",500);
spq.getResultList();
コードをステップ実行したときに見たものとログにあるものに基づいて、これは私が見る sql ステートメントです。
CALL prc_get_all_appl_var(ip_cus_set_c = ?, ip_cps_ver_n = ?, op_sqlstate = ?, op_sqlcode = ?, op_msg = ?)
しかし、そうあるべきです
CALL prc_get_all_appl_var("CONS",500,?,?,?)
これがスタックトレースです。
