Question

存储过程（仅限规范）：

CREATE OR REPLACE PACKAGE "PACK_USER"     
as   
type contact is table of nvarchar2(50) INDEX BY BINARY_INTEGER;  
procedure create_user(  
user_id out number,  
pwd in nvarchar2,  
birthday in date,  
gender in number,  
address in nvarchar2,  
realName in nvarchar2,  
identity in nvarchar2,  
salary in float,  
contractTime in date,  
departmentId in number,  
positionId in number 
);  
end pack_user;
/

当我从蟾蜍打电话时，没关系。但是当我从hibernate调用它时，它说“无效的SQL语句”，但没有显示原因。 hibernate映射：

<sql-query name="create_user" callable="true">
    <return-scalar column="user_id" type="integer"/>
    { call PACK_USER.CREATE_USER(?,:pwd,:birthday,:gender,:address,:realName,:identity,:salary,:contractTime,:departmentId,:positionId)}
</sql-query>

呼叫：

Session session = this.getSession();
Query q = session.getNamedQuery("create_user");
q.setString("pwd", userInfo.getIndentity());
q.setDate("birthday", userInfo.getBirthday());
q.setInteger("gender", userInfo.isGender() ? 1 : 0);
q.setString("address", userInfo.getHomeAddress());
q.setString("realName", userInfo.getRealname());
q.setString("identity", userInfo.getIndentity());
q.setFloat("salary", userInfo.getBaseSalary());
q.setDate("contractTime", userInfo.getContractTime());
q.setInteger("departmentId", userInfo.getDepartmentId());
q.setInteger("positionId", userInfo.getPositionId());
int res = (Integer)q.uniqueResult();
return res;

PS：由于这是一个课程项目，因此需要oracle和存储过程，而hibernate则不需要。
我已经尝试将程序移出包，或者创建一个函数而不是过程。两者都不起作用。

您的配置文件可能存在一些问题，请参阅下面的示例以获得更多说明：

CREATE OR REPLACE PROCEDURE SP_LIB_DTL(p_cursor    out sys_refcursor,
                                       in_brnch_cd in number,
                                       in_auth_cd in number)
as
  bookName varchar2(8);
  ISBN     number;
begin
  bookName := null;
  ISBN     := 0;
  open p_cursor for
    select l.book_name, l.isbn_nbr
      into bookName, ISBN
      from LIB_BRNCH_DTL l
     where l.branch_code = in_brnch_cd
     and l.auth_code = in_auth_cd;

end;

Hibernate xml

<?xml version=”1.0″ encoding=”utf-8″?>
<!DOCTYPE hibernate-mapping PUBLIC “-//Hibernate/Hibernate Mapping DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd“>
<hibernate-mapping>
<class name=”com.org.lib.LibraryDetails”>
<id name=”ISBN” type=”long” />
<property name=”bookName” type=”string” />
</class>
 <sql-query name=”LIB_SP” callable=”true”>
 <return class=”com.org.lib.LibraryDetails”>
   <return-property name=”ISBN” column=”isbn_nbr” />
   <return-property name=”bookName” column=”book_name” />
 </return>
  {  call SP_LIB_DTL(? , :branchCD ,:authorCD) }
 </sql-query>
</hibernate-mapping>

确保为返回属性映射的列属性使用了正确的数据库字段名称值。如果未映射正确的数据库字段名称

，将会出现以下错误

无法执行查询;错误的SQL语法[{call SP_LIB_DTL（？，？）}]; 嵌套异常是java.sql.SQLException：列名无效

以下是执行查询和设置绑定参数值的DAO实现。

public  List selectBooks(final BigDecimal branchCode,final BigDecimal authorCode){
        return (List) getHibernateTemplate().execute(new HibernateCallback() {
              public Object doInHibernate(Session session) throws HibernateException, SQLException
              {
                  Query q = session.getNamedQuery(“LIB_SP”);
                  q.setLong(“branchCD”, branchCode.longValue());
                  q.setLong(“authorCD”, authorCode.longValue());
                  return q.list();
              }
          });
      }
