Question

我通过Hibernate使用OUT参数调用了一个存储过程，并出现以下错误：

17:30:52,646 ERROR [STDERR] Caused by: java.sql.SQLException: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'GET_ACTIVITY_RECORDS'
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'GET_ACTIVITY_RECORDS'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

我的存储过程：

  create or replace 
    PACKAGE BODY  "TEST_NESTEDTAB_PKG" AS

      PROCEDURE GET_ACTIVITY_RECORDS( TEMP_RESULT OUT ACT_LOG_TYPE, USERNAME IN ACTIVITY_LOG.USER_NAME%TYPE) AS
      BEGIN
        SELECT * BULK COLLECT INTO TEMP_RESULT
        FROM ACTIVITY_LOG
        WHERE USER_NAME  = USERNAME;
      END GET_ACTIVITY_RECORDS;

    END TEST_NESTEDTAB_PKG;

Hibernate映射：

 <sql-query name="getactivityLog" callable="true">
    <return class="com.test.ps.domain.SPActiveLog">
        <return-property name="activityId" column="ACTIVITY_ID" />
        <return-property name="username" column="USER_NAME" />
        <return-property name="activityDate" column="ACTIVITY_DATE" />
        <return-property name="activity" column="ACTIVITY" />
        <return-property name="userId" column="USERID" />
        <return-property name="action" column="ACTION" />
        <return-property name="userRole" column="USER_ROLE" />
        <return-property name="description" column="DESCRIPTION" />
        <return-property name="category" column="CATEGORY" />
        <return-property name="result" column="RESULT" />
    </return>
    { call TEST_NESTEDTAB_PKG.GET_ACTIVITY_RECORDS(?,:USERNAME) }
</sql-query>

我按如下方式调用了存储过程：

    Query qry = getSession().getNamedQuery("getactivityLog");       
    qry.setParameter("USERNAME", "FACTORY TOPTAR TOTAIN");
    Object result = qry.list();

有人能解释这段代码有什么问题吗？

试试这个：

{ ? = call TEST_NESTEDTAB_PKG.GET_ACTIVITY_RECORDS(:USERNAME) }

<强> 16.2.2。使用存储过程进行查询

Hibernate 3通过存储过程引入了对查询的支持   功能。 以下大多数文档都是等效的。   存储过程/函数必须返回结果集作为第一个   out-parameter能够使用Hibernate。这样一个例子   Oracle 9及更高版本中的存储函数如下：

CREATE OR REPLACE FUNCTION selectAllEmployments
    RETURN SYS_REFCURSOR
AS
    st_cursor SYS_REFCURSOR;
BEGIN
    OPEN st_cursor FOR
 SELECT EMPLOYEE, EMPLOYER,
 STARTDATE, ENDDATE,
 REGIONCODE, EID, VALUE, CURRENCY
 FROM EMPLOYMENT;
      RETURN  st_cursor;
 END;

要在Hibernate中使用此查询，您需要通过命名查询映射它。

<sql-query name="selectAllEmployees_SP" callable="true">
    <return alias="emp" class="Employment">
        <return-property name="employee" column="EMPLOYEE"/>
        <return-property name="employer" column="EMPLOYER"/>
        <return-property name="startDate" column="STARTDATE"/>
        <return-property name="endDate" column="ENDDATE"/>
        <return-property name="regionCode" column="REGIONCODE"/>
        <return-property name="id" column="EID"/>
        <return-property name="salary">
            <return-column name="VALUE"/>
            <return-column name="CURRENCY"/>
        </return-property>
    </return>
    { ? = call selectAllEmployments() }
</sql-query>

注意存储过程目前只返回标量和实体。并且不受支持。
