java - ORA-00979 : not a GROUP BY expression

Question

我在我的 DAO 实现中创建了运行查询的函数

SQL 查询:

  SELECT pct.IA_FILING_METHOD_CODE_ID, COUNT(*) 
            FROM Ia_Dossier pct 
            WHERE 1=1 and pct.INTERNATIONAL_FILING_DATE IS NOT NULL 
            AND pct.INTERNATIONAL_FILING_DATE>='11-SEP-08' 
            AND pct.INTERNATIONAL_FILING_DATE<='11-SEP-16' 
            GROUP BY pct.IA_FILING_METHOD_CODE_ID 
            HAVING pct.IA_FILING_METHOD_CODE_ID IS NOT NULL 

这在数据库中运行良好，但从 hibernate 代码运行时出错。

功能:

    @Override
    public List<Object[]> findStatsByROGroupedByFileFormat(Date startDate, Date endDate,String RO, String groupBy) {

        StringBuilder jpqlQuery = new StringBuilder();
        jpqlQuery.append("Select pct.").append(groupBy).append(",count(*) from IaDossier as pct where 1=1 and pct.internationalFilingDate is not null");
        if(startDate!=null)
        {
            jpqlQuery.append(" and pct.internationalFilingDate >=:startDate");
        }
        if(endDate!=null)
        {
            jpqlQuery.append(" and pct.internationalFilingDate <=:endDate");
        }

        if(groupBy!=null && RO!=""){
            jpqlQuery.append(" group by pct.").append(groupBy);
            jpqlQuery.append(" having pct.").append(groupBy).append(" is not null");
        }
System.out.println(jpqlQuery+"hc");
        Query q = entityManager.createQuery(jpqlQuery.toString());
        if(startDate!=null)
        {
            q.setParameter("startDate", startDate);
        }
        if(endDate!=null)
        {
            q.setParameter("endDate", endDate);
        }
        return (List<Object[]>)q.getResultList();
    }

我不知道为什么当查询在 sql developer 中正常运行时会出现此 GROUP BY 错误。

你想做什么？？

当您使用 HAVING 子句时，您必须在此处指定的列上使用聚合函数，因为您正在对该查询进行分组。我只是将其更改为一个简单的 WHERE 子句，无需在 HAVING 中指定。

SELECT pct.IA_FILING_METHOD_CODE_ID, COUNT(*) 
FROM Ia_Dossier pct 
WHERE pct.INTERNATIONAL_FILING_DATE IS NOT NULL 
    AND pct.INTERNATIONAL_FILING_DATE>='11-SEP-08' 
    AND pct.INTERNATIONAL_FILING_DATE<='11-SEP-16'
    AND pct.IA_FILING_METHOD_CODE_ID IS NOT NULL
 GROUP BY pct.IA_FILING_METHOD_CODE_ID 

The Oracle HAVING clause is used in combination with the GROUP BY clause to restrict the groups of returned rows to only those whose the condition is TRUE.
