休眠 - 無法讀取表中的值

無法通過休眠讀取表中的數據。 但在TOAD中工作的SQL相同。休眠 - 無法讀取表中的值

SQL：

SELECT distinct pub.asdfg, pub.list, pub.prod, pub.prod_desc FROM Pubsh pub WHERE pub.prod in ('123456')

表DEF：

org.hibernate.SQL - SELECT distinct pub.nel, pub.list, pub.prod, pub.prod_desc FROM PUBSH WHERE pub.prod in ('12345') 
     org.hibernate.jdbc.AbstractBatcher - about to open ResultSet (open ResultSets: 0, globally: 0) 
      org.hibernate.type.StringType - could not read column value from result set; Invalid column name 
     org.hibernate.jdbc.AbstractBatcher - about to close ResultSet (open ResultSets: 1, globally: 1) 
     org.hibernate.jdbc.AbstractBatcher - about to close PreparedStatement (open PreparedStatements: 1, globally: 1)

DAO方法來執行休眠：：在控制檯

CREATE TABLE "PUBSH" 
(
    KEY decimal(22) NOT NULL, 
    PROD varchar2(54) NOT NULL, 
    PRODKEY decimal(22), 
    PROD_DESC varchar2(360), 
    PARTEY decimal(22) NOT NULL, 
    LIST_TYPE varchar2(90), 
    PUBLISH_DATE date, 
    PUBSH_PERIOD varchar2(30) NOT NULL, 
    PL_KEY decimal(22), 
    LIST varchar2(750), 
    EL_KEY decimal(22), 
    NEL varchar2(60) }

錯誤

public List<SearchResult> find(final String Query1) { 
     return (List<SearchResult>)getHibernateTemplate().execute(new HibernateCallback(){ 
     public Object doInHibernate(Session session) throws HibernateException{ 
      Query query1 = session.createSQLQuery(channelQuery1) 
            .addScalar("nel",Hibernate.STRING) 
            .addScalar("price",Hibernate.STRING) 
            .addScalar("prodr",Hibernate.STRING) 
            .addScalar("prodcr",Hibernate.STRING) 
            .setResultTransformer(Transformers.aliasToBean(SearchResult.class)); 

       return query1.list(); 
      }

請告知爲什麼我在訪問通過休眠時收到無效的列名錯誤？

Query1的值是什麼？還激活SQL查詢日誌，看到休眠正在執行的查詢 – fmodos

查詢1沒有執行，我在執行問題部分中執行休眠和SQL日誌時出錯。 – user2444474

請不要以這種方式從你的問題中刪除內容，因爲它會使答案看起來不相關。在那裏我沒有看到任何遠程「保密」的東西。當您發佈內容時，您同意獲得CC-WIKI許可證。 –

您正在創建一個SQL查詢，但標性比一個表中的聲明不同：

.addScalar("prodNbr",Hibernate.STRING) 
.addScalar("prodDescr",Hibernate.STRING)

這些屬性的聲明在表PROD_NBR和PROD_DESC，所以代碼更改爲

.addScalar("CHANNEL",Hibernate.STRING) 
.addScalar("PRICELIST",Hibernate.STRING) 
.addScalar("PROD_NBR",Hibernate.STRING) 
.addScalar("PROD_DESC",Hibernate.STRING)
