根据计数查询的结果插入记录数

Question

我有一个应用程序可以跟踪管理员在admin_comments表中执行的操作。

最近，我被要求创建一个新表admin_stats，以跟踪应用程序某些区域的生产力。

我已经在我的代码逻辑中实现了这一点，因此我们会跟踪所有统计信息，但是他们问我是否也可以通过在admin_comments表中搜索来添加所有以前的统计信息适当的领域。

我的admin_comments表格如下：

+----+---------+----------+---------+------+
| id | user_id | admin_id | comment | type |
+----+---------+----------+---------+------+

这样的admin_stats表：

+----+----------+---------+------+--------+
| id | admin_id | user_id | type | action |
+----+----------+---------+------+--------+

首先，我只想将声明导入此表。声明可以是approved，rejected，temporarily rejected或permanently rejected，我已使用此查询获取管理员的每项操作的计数：

select admin_id, 
    SUM(CASE WHEN comment like 'Approved the claim for%' THEN 1 ELSE 0 END) as Approved,
    SUM(CASE WHEN comment like 'Rejected the claim for%' THEN 1 ELSE 0 END) as Rejected,
    SUM(CASE WHEN comment like 'Temporarily rejected (24 hour hold) the claim for%' THEN 1 ELSE 0 END) as TempReject, 
    SUM(CASE WHEN comment like 'Permanently rejected the claim for%' THEN 1 ELSE 0 END ) as PermReject
from admin_comments
where admin_id > 0
group by admin_id

产生如下结果：

有没有办法可以根据每个admin_id的计数执行插入？

即从上图中我想将{1}}中的一条记录插入admin_stats，其中action为应用，{1}为拒绝type的记录使用action作为type 1的应用程序。

对于admin_id 4，我想插入25个已批准的admin_id，12个被拒绝的actions和2个actions行动。

因此，每个操作都应作为新行输入，tempreject将永远是应用程序。

我认为你正在尝试这样做。

insert into admin_stats(admin_id,type,action) --add other columns as needed
select admin_id,'application' as type,
case when comment like 'Approved the claim for%' then 'Approved'
     when comment like 'Rejected the claim for%' then 'Rejected'
     when comment like 'Temporarily rejected (24 hour hold) the claim for%' then 'TempReject'
     when comment like 'Permanently rejected the claim for%' then 'PermReject'
end as action
from admin_comments
where admin_id > 0
and (comment like 'Approved the claim for%'
     or comment like 'Rejected the claim for%'
     or comment like 'Temporarily rejected (24 hour hold) the claim for%'
     or comment like 'Permanently rejected the claim for%')
