Question

我正在尝试在Apache Phoenix中执行查询，我在使用aggregate和groupby函数。我已经在mysql中执行了相同的查询，它可以工作，但在凤凰城我尝试了基于mysql查询的查询，但它失败了。请参阅下面的mysql查询和Phoenix查询。

MySQL：

select id3, id4, name, descr, status, min(date) from table1
where status = "inactive" group by id3, id4, name, descr, status

结果：
id3 id4 name descr status min（date）

17773 8001300701101 name1 descr1 INACTIVE 20121202
17785 9100000161822 name3 descr3 INACTIVE 20121201

凤凰查询：

MySQL和Phoenix之间的查询没有区别。

select id3, id4, name, descr, status, min ( date )  from table1
WHERE status = 'inactive' group by  id3, id4, name, descr, status;

但我得到以下错误可以解释一下吗？

Error: ERROR 1018 (42Y27): Aggregate may not contain columns not in GROUP BY. ELS_NAME (state=42Y27,code=1018)

您可能需要检查列命名。

所有表格，列系列和列名称都是大写的，除非它们是双引号，在这种情况下它们区分大小写。
