java - 将日期作为存储过程中的参数传递(oracle)

Question

我正在尝试从 hibernate 执行插入操作到 oracle 表。 我的存储过程是:-

create or replace PROCEDURE          ADMSN_TABLE (
  P_ID                            NUMBER,
  P_ADMISSIONFOR                  VARCHAR2,
  P_SUBMISSIONDATE                DATE,                            --NOT NULL
  P_SUBMISSIONLASTDATE            DATE                          --NOT NULL

)
IS
  v_sno number;

  BEGIN
      INSERT INTO ORACLE.ADMISSION(AMSNID,ADMISSIONFOR,SUBMISSIONDATE,
 SUBMISSIONLASTDATE)
      VALUES (P_ID,P_ADMISSIONFOR,P_SUBMISSIONDATE,P_SUBMISSIONLASTDATE);

      COMMIT;
  END;

我从 hibernate 状态调用此过程的方式:-

    public void callProc(){

        Date utilDate= new Date();
        java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());
        System.out.println(sqlDate);


        Date date = new Date();
        SimpleDateFormat smd = new SimpleDateFormat("dd-MMM-YYYY");
        String sdate = smd.format(date);
        System.out.println(sdate);

    try {
    session = sessionFactory.openSession();
    transaction = session.beginTransaction();
    StoredProcedureQuery query = session.createStoredProcedureQuery("ADMSN_TABLE");
query.registerStoredProcedureParameter("P_ID", Number.class, 
ParameterMode.IN);
query.registerStoredProcedureParameter("P_ADMISSIONFOR", String.class, 
ParameterMode.IN);
query.registerStoredProcedureParameter("P_SUBMISSIONDATE", Date.class, 
ParameterMode.IN);             
query.registerStoredProcedureParameter("P_SUBMISSIONLASTDATE",Date.class, 
ParameterMode.IN);

            query.setParameter("P_ID", 1);
            query.setParameter("P_ADMISSIONFOR", "schoolfee");
            query.setParameter("P_SUBMISSIONDATE", sqlDate);
            query.setParameter("P_SUBMISSIONLASTDATE", sqlDate);
            query.execute();
            System.out.println("excuted");
        }catch(Exception ex){
            ex.printStackTrace();
        }
    }
}

现在我尝试将日期参数作为 new Date() 或 sqldate 传递，如上面给出的。和 query.setParameter("P_SUBMISSIONLASTDATE", sqlDate,TemporalType.Date); 但它们都抛出错误:-

Answer 1

一种可能的解决方案是使用 java.sql.timestamp 而不是 java.sql.Date。也可以引用SQL and PL/SQL Mappings to Oracle and JDBC Types以验证正确的数据类型映射。

This is an example of how get java.sql.timestamp

java.util.Date utilDate = new java.util.Date();
Calendar cal = Calendar.getInstance();
cal.setTime(utilDate);
cal.set(Calendar.MILLISECOND, 0);
System.out.println(new java.sql.Timestamp(utilDate.getTime()));
System.out.println(new java.sql.Timestamp(cal.getTimeInMillis()));
