Question

当我尝试在Birt中执行此查询时：

select a.ag_code , COUNT(distinct(a.usr_id)),b.AG_NAME
from photo a, 
     (select ag_code,AG_NAME from  agent 
      WHERE AG_TYPE = 'AS' AND AG_USEFLAG = 'Y' AND AG_NAME LIKE 'M%')b
where a.upload_time BETWEEN TO_DATE('20131116000000','yyyymmddhh24miss')
                        AND TO_DATE('20131129235959','yyyymmddhh24miss')
  and a.status = 'S'
  and a.ag_code = b.ag_code
group by a.ag_code,b.AG_NAME
order by a.Ag_CODE,b.AG_NAME;

出现此例外：

Answer 1

尝试使用不同的计数列别名 - 如下所示：

select a.ag_code , COUNT(distinct(a.usr_id)) as distinct_users, b.AG_NAME

...

Answer 2

你需要删除“;”在您的查询结束时。添加“;”可能适用于大多数工具（如PL / SQL Developer），但这些工具正在删除“;”在发送给oracle之前。

Answer 3

错误消息的这一部分

由引起：org.eclipse.birt.data.engine.odaconsumer.OdaDataException：无法获取结果集元数据。 org.eclipse.birt.report.data.oda.jdbc.JDBCException：SQL语句不返回ResultSet对象。 SQL错误＃1：ORA-00911：无效字符

表示您的SQL不好，Mark Bannister提出了一个解决方案。依赖于SQL的错误，错误消息的这一部分可能会更有帮助，可以调出特定区域进行审核。

可以在数据库中执行我的查询，但在Birt异常白羊座中尝试时
