Unable to call Stored procedure from hibernate

Please try to answer the problem in the below code for calling a stored procedure in ORACLE from hibernate . i am using a named query in hbm file to be called from the testclient.java .

Hibernate3.2.1 core file is being used.
My stored procedure:

create or replace procedure get_empdetails2(mycursor out sys_refcursor, cond in varchar2)

open mycursor for

select eb.first_name,eb.last_name from employee3 eb where eb.email like cond ;



public class Employee{

public Employee()
private int eid;
private String fname,lname,email;
public int getEid() {
return eid;
public void setEid(int eid) {
this.eid = eid;
public String getFname() {
return fname;
public void setFname(String fname) {
this.fname = fname;
public String getLname() {
return lname;
public void setLname(String lname) {
this.lname = lname;
public String getEmail() {
return email;
public void setEmail(String email) {
this.email = email;


table employee3:

Column Name Data Type Nullable Default Primary Key
EMAIL VARCHAR2(20) Yes - -


<?xml version='1.0' encoding='UTF-8'?>

<return-property name="fname" column="FIRST_NAME"/>
<return-property name="lname" column="LAST_NAME"/>

{call get_empdetails2(?,?)}



In the call get_empdetails(?,?) , the first ? is used for output mycursor which as per the hibernate doc must be the first parameter and second ? is the input parameter for the cond variable in procedure.
My output error is :

As present in the output , i am getting this - could not read column . whats wrong in the configuration?


Answer Source

Hibernate is trying to map whole table from return result of Stored Procedure. You are returning eb.first_name,eb.last_name from Stored Procedure.

Possible Solution 1:

Select all field in Stored Procedure SELECT query like select * from employee3 eb where eb.email like cond ;

If solution 1 works for you then use it but if you want to return only two fields from stored procedure I'd suggest you second solution. As I don't know how we can execute named query which returns only selected fields.

Possible Solution 2:

Use SQLQuery. I used it with MySQL You can try for Oracle. Hope it will work.

Query callStoredProcedure_MYSQL = session.createSQLQuery("CALL SP_MYSQL_HIBERNATE (:param1, :param2, :param3)");
callStoredProcedure_MYSQL.setInteger("param1", 10);
callStoredProcedure_MYSQL.setInteger("param2", 10);
callStoredProcedure_MYSQL.setString("param3", "test");*/

/* callStoredProcedure_MYSQL.list() will execute stored procedure and return the value */
List customResult = callStoredProcedure_MYSQL.list();
if (customResult != null && !customResult.isEmpty()) {
 Object[] obj = customResult.get(0);
