roql - ROQL 按字段组合分组

Question

我正在使用 Oracle RightNow，它使用 MySQL，但不能有嵌套查询，只能选择（双关语！）数量的命令供我使用：http ://documentation.custhelp.com/euf/assets/devdocs/august2016/Connect_PHP /Content/Connect%20for%20PHP%20API/RightNow%20Object%20Query%20Language/ROQL%20and%20Common%20Objects.htm

不允许使用 CASE 语句

假设我有

Select Count(*) as Amount, Category 
From MyTable
Group by Category

一切都很好，我得到一张如下表

Amount | Category
---------------------
1      | Contact Editor
4      | Incident Editor
787    | Raise a Request
78     | Pending Information

我将如何修改我的查询，以便我可以合并前两行以获得一个新的更新表

Amount | Category
---------------------
5      | Editor
787    | Raise a Request
78     | Pending Information

谢谢

Answer 1

尝试使用case表达式进行分组：

select Count(*) as Amount,  case when Category in('Contact Editor', 'Incident Editor') then 'editor' else Category end
From MyTable
Group by case when Category in('Contact Editor', 'Incident Editor') then 'editor' else Category end

Answer 2

select count(*), 
case when Category like '%Editor' then 'Editor' else Category end as Category
From MyTable
Group by Category
