Oracle sql查询以按几列分组获取记录

我需要从Oracle中的几个表中获取记录。 查询我有如下返回记录

假设您当前的查询工作正常，那么它在Oracle中似乎无效，您可以将其用作CTE并获得所需的结果。例如：

with
x (appcount, typeid, name) as (
  -- your current query here...
)
select 
  sum(case when typeid = 1 then 1 else 0 end) as type1,
  sum(case when typeid = 2 then 1 else 0 end) as type2,
  sum(case when typeid = 3 then 1 else 0 end) as type3,
  name
from x
group by name

---

直接在查询中使用分组依据和大小写，如下所示：

select 
  sum(case when t3.id = 1 then 1 end) as type1,
  sum(case when t3.id = 2 then 1 end) as type2,
  sum(case when t3.id = 3 then 1 end) as type3,
  t2.name
from t0 ra
Join table1 t1 on t1.id = ra.id
Join table2 t2 on t2.id = ra.id
join table3 t3 on t3.id = ra.typeid
where t1.column1 = 1
Group by t2.name;

干杯

您确定第一个查询在Oracle中有效吗？您没有GROUPBY子句，但某些列是聚合的…如果我不清楚我的问题，很抱歉。但Tejash的回答对我有效。
