Question

我有很大的问题无法弄清楚问题，非常感谢提前感谢帮助。

        con = getConnection(SFPQueries.DATASOURCE);         
        stmt1 = con.prepareStatement("SELECT DISTINCT A.SUMMARIZATION_QUERY, A.AGGREGATE_ID, B.TOKEN, C.FACT_TOKEN, D.FIELD_ID, D.MEASURES "+
                "FROM SUMMARIZATION_TIME_AGGRREGATE_MAPPING_TB A, SUMMARIZATION_TB B, FACT_TB C, SUMMARIZATION_MEASURES_MAPPING_TB D "+
                "WHERE A.SUMMARIZATION_ID=B.SUMMARIZATION_ID AND B.FACT_ID=C.FACT_ID AND A.SUMMARIZATION_ID=D.SUMMARIZATION_ID AND A.AGGREGATE_ID=?");
        stmt1.setInt(1,1);
        rs1 = stmt1.executeQuery();
        if(_log.isDebugEnabled()){_log.debug(" >> BEFORE " + rs1.next());}

对于上述JDBC查询，JDBC始终没有返回任何结果。

10/04/2014 11：41：56.866 INFO com.hp.sfp.core.dao.impl.BaseDAO：输入getConnection（） 10/04/2014 11：41：57.253 INFO com.hp.sfp.core.dao.impl.BaseDAO：数据库信息：Url = jdbc：vertica：// * / ABCD用户名= xyz密码= XYZ @ 123 10/04/2014 11：41：57.254 INFO com.hp.sfp.core.dao.impl.BaseDAO：退出getConnection（） 10/04/2014 11：41：57.382 DEBUG com.hp.sfp.core.dao.impl.SummarizationJobDAOImpl：＆gt;＆gt;错误之前

但是当我在shell上使用相同的查询时，我得到了结果！

=> SELECT DISTINCT A.SUMMARIZATION_QUERY, A.AGGREGATE_ID, B.TOKEN, C.FACT_TOKEN,    D.FIELD_ID, D.MEASURES FROM SUMMARIZATION_TIME_AGGRREGATE_MAPPING_TB A, SUMMARIZATION_TB B, FACT_TB C, SUMMARIZATION_MEASURES_MAPPING_TB D WHERE A.SUMMARIZATION_ID=B.SUMMARIZATION_ID AND B.FACT_ID=C.FACT_ID AND A.SUMMARIZATION_ID=D.SUMMARIZATION_ID AND A.AGGREGATE_ID=1;
SUMMARIZATION_QUERY | AGGREGATE_ID |       TOKEN        | FACT_TOKEN | FIELD_ID |        MEASURES
---------------------+--------------+--------------------+------------+----------+---------
select * from ...   |            1 | summary_for_charge | chargefact |       37 |    CALL_END_CAUSE
select * from ...   |            1 | summary_for_charge | chargefact |        1 | STRUCTURE_CODE

对不起，有人向我解释说我没有跑过去'COMMIT＆＃39;。所以在数据库shell上它显示了结果，而不是通过JDBC我不能。这就是问题所在。

JDBC Query不会返回任何结果，但相同的查询在数据库shell上有效
