java.sql.SQLException：无法对PLSQL语句执行提取操作：next。在Hibernate中 [英] java.sql.SQLException: Cannot perform fetch on a PLSQL statement: next. In Hibernate

问题描述

  java.sql.SQLException：Can not在PLSQL语句中执行fetch：next从hibernate调用存储过程
  

任何人都可以帮我解决这个问题？

Hibernate错误低于

java.sql.SQLException：无法对PLSQL语句执行提取操作：next

解决方案

存储过程只是打印查询的结果，它不会返回它。所以你不能在Java / Hibernate中得到它的结果。

I am really stuck here, every time I am calling procedure hibernate is showing error

java.sql.SQLException: Cannot perform fetch on a PLSQL statement: next when calling stored procedure from hibernate

Can anyone help me out from this?

Procedure

CREATE OR REPLACE PROCEDURE TESTP(
pmaxrows IN NUMBER :=3 )
AS
in_clause VARCHAR2(256);
sel_query VARCHAR2(256);
n         NUMBER := 0;
BEGIN
FOR x IN
(SELECT DISTINCT VENDOR_ID FROM MF_QUOTATIONS 
)
LOOP
IF n        <> 0 THEN
in_clause := in_clause || ', ';
END IF;
in_clause := in_clause || '''' || x.VENDOR_ID || '''';
n         := 1;
END LOOP;
sel_query := 'select * from (select ITEM_ID, VENDOR_ID, TOTAL from 
MF_QUOTATIONS) pivot (max(TOTAL) for VENDOR_ID in ('||in_clause||'));';
dbms_output.put_line (sel_query);

END TESTP; 

Hibernate

Query q = session.getCurrentSession().getNamedQuery("callStockStoreProcedure")
        .setParameter("pmaxrows", 3);


    System.out.println("q="+q);


    List result = q.list();


    return result;

Entity class

@Entity
@Table(name="MF_QUOTATIONS")

@NamedNativeQueries({
@NamedNativeQuery(
name = "callStockStoreProcedure",
query = "CALL TESTP(:pmaxrows)",
resultClass = Quotations.class
)
})


public class Quotations {
..........
.......... 
}

Hibernate errors are below

java.sql.SQLException: Cannot perform fetch on a PLSQL statement: next

解决方案

The stored procedure just prints the result of the query, it does not return it. So you can't get its result in Java/Hibernate.
