Sql 在现有子查询中添加另一个子查询

是否可以从相同的表日期记录中获得如下结果：

               Enrolled   Enrolled as Email  Enrolled as Text Deals Redeemed   
<First Date>   7          5                  2                6
<Next Date>    9          3                  6               14

我当前的查询如下：

Customer_id, field1, field2, responsecode, created_date

select created_date,
   count(field1) Enrolled,
   count(case field1 when 'E-mail' then 1 end) Enrolled_as_Email,
   count(case field1 when 'Cell Phone' then 1 end) Enrolled_as_Cell,
   count(responsecode) Deals_Redeemed
   from tblCustomer
   group by created_date
   order by created_date

这对于前三列很好，但是对于“Deals Received”这四列很好，这是来自另一个表的子查询

Select COUNT(*) from tbl_TransactionDishout where DishoutResponseCode = '0000'

表结构如下：
表名为“tbl_TransactionDishout”

你能这样试试吗。（所有行的Deals_赎回值都相同，您说过两个表之间没有关系）

如果您的tbl_TransactionDishout有一个连接到您的tbl客户的连接ID列，您应该能够执行单独的查询，例如

select created_date,
count(field1) Enrolled,
count(case field1 when 'E-mail' then 1 end) Enrolled_as_Email,
count(case field1 when 'Cell Phone' then 1 end) Enrolled_as_Cell,
cnt
from tblCustomer t, 
(select id, count(1) as cnt
from tbl_transactiondishout
group by id) tt
where t.id = tt.id
group by created_date
order by created_date

---

也许是这样的：

select 
    created_date,
    count(field1) Enrolled,
    count(case field1 when 'E-mail' then 1 end) Enrolled_as_Email,
    count(case field1 when 'Cell Phone' then 1 end) Enrolled_as_Cell,
    (
        Select COUNT(*) 
        from tbl_TransactionDishout 
        where DishoutResponseCode = tblCustomer.responsecode
    ) as Deals_Redeemed
from 
    tblCustomer
group by 
    created_date
order by 
    created_date

tbl客户和tbl_交易之间的关系是什么？DishoutResponseCode是responsecode吗？它们之间没有关系..我只希望结果按日期顺序显示..这个id是什么。。？？这两者之间没有关系。那么，下一个最好的方法是在日期加入，并按日期获得交易的计数，然后使用上述概念在日期加入到您的客户表中。。。

select created_date,
count(field1) Enrolled,
count(case field1 when 'E-mail' then 1 end) Enrolled_as_Email,
count(case field1 when 'Cell Phone' then 1 end) Enrolled_as_Cell,
cnt
from tblCustomer t, 
(select id, count(1) as cnt
from tbl_transactiondishout
group by id) tt
where t.id = tt.id
group by created_date
order by created_date

select 
    created_date,
    count(field1) Enrolled,
    count(case field1 when 'E-mail' then 1 end) Enrolled_as_Email,
    count(case field1 when 'Cell Phone' then 1 end) Enrolled_as_Cell,
    (
        Select COUNT(*) 
        from tbl_TransactionDishout 
        where DishoutResponseCode = tblCustomer.responsecode
    ) as Deals_Redeemed
from 
    tblCustomer
group by 
    created_date
order by 
    created_date
