Объединение двух запросов в один

Question

структуры таблицы:
tblCustomer

Customer_id created     field1   field2  cardno 
-------------------------------------------------------------------------------  
1014   2010-05-25 12:51:59.547 Cell Phone  abc@lmn.com 1234567890 
1015   2010-08-15 12:51:59.547 Email    abc@xyz.com 2345678891 

tbl_TransactionDishout

Trnx_id offerNo TerminalID  Created     VirtualCard 
------------------------------------------------------------------- 
1   1014  170924690436418 2010-05-25 12:51:59.547 1234567890 

Можно ли получить результат, как показано ниже даты мудр записей:

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

У меня есть два разных запроса, которые мне нужно объединить в один. Первый:

select 
    CAST(FLOOR(CAST(t.created AS FLOAT)) as Datetime) created, 
    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 
    from tblCustomer as t 
    group by t.created 
    order by t.created desc 

Какие Дисплей:

create     Enrolled Enrolled_as_Email Enrolled_as_Cell 
    ---------------------------------------------------------------------- 
    2012-03-01 00:00:00.000 3  1    2 
    2012-02-29 00:00:00.000 1  0    1 

Второй:

select CAST(FLOOR(CAST(t.created AS FLOAT)) as Datetime) created, 
    count(*) [Deals_Redeemed] from tbl_TransactionDishout t 
    left join tblCustomer c on t.VirtualCard = c.cardno 
    group by CAST(FLOOR(CAST(t.created AS FLOAT)) as Datetime) 
    order by t.created desc 

который отображает:

create     Deals_Redeemed 
    --------------------------------------- 
    2012-03-02 00:00:00.000 1 
    2012-03-01 00:00:00.000 6 
    2012-02-28 00:00:00.000 1 
    2012-02-27 00:00:00.000 2 

Теперь я хочу, запись, которая содержит дату, начиная с филиал го и должны быть объединены в один.

Но это дает мне результат дня, содержащийся только в tblCustomer таблице ..

Теперь, как получить Deals_redeemed ..? соотношение между tbl_transaction и tblCustomer оказывает такой же cardno ...

Answer 1

SELECT 
    CAST(t1.created AS DATE) created, 
    COUNT(t1.field1) Enrolled, 
    COUNT(CASE t1.field1 WHEN 'E-mail' THEN 1 END) Enrolled_as_Email, 
    COUNT(CASE t1.field1 WHEN 'Cell Phone' THEN 1 END) Enrolled_as_Cell, 
    COUNT(t2.created) Deals_Redeemed 
FROM tblCustomer AS t1 
LEFT JOIN tbl_TransactionDishout t2 
    ON t1.cardno = t2.VirtualCard 
GROUP BY CAST(t1.created AS DATE) 
ORDER BY CAST(t1.created AS DATE) DESC 

Edit: Изменено условие cardno, и изменяется от FULL JOIN до LEFT JOIN.

Answer 2

Вы мог Pivot():

select [create] 
, sum([Email]+[Cell Phone]) as [Enrolled] 
, max([Email]) as [Enrolled as Email] 
, max([Cell Phone]) as [Enrolled as Cell Phone] 
, max([Deal Redeemed]) as [Deals Redeemed] 
from (
    select [create]=created 
    , create1=created 
    , field1 
    from tblCustomer 
    union all 
    select [create]=created 
    , create1=created 
    , field1='Deal Redeemed' 
    from tbl_TransactionDishout 
) p 
pivot (
    count(create1) 
    for field1 in ([Cell Phone],[Email],[Deal Redeemed]) 
) pv 
group by [create] 
order by [create]
