MySQL查詢分組子查詢問題

由於某種原因，我無法繞過此查詢，因此我想知道是否有人能夠在此幫助我。我有以下3個表：MySQL查詢分組子查詢問題

opp_cstm：

 
id_c make_c  time_followup_c lead_category_c lead_type_c 
9  GMC   224    GM    Internet Sales 
e  Buick  809    GM Internet  Service 
8  GMC   1559   Dealer Web  Sales 
2  Cadillac  10596   Dealer Web  Service 
3  Chevrolet 15595   GM Internet  Sales 
4  Chevrolet 905   GM Internet  Service

機會：

 
id date_entered   deleted 
2 2010-07-16 16:46:21  0 
3 2010-07-16 16:55:53  0 
4 2010-07-16 19:30:12  0 
8 2010-07-16 16:44:13  0 
9 2010-07-16 16:39:17  0 
e 2010-07-16 16:41:44  0

leads_objectives：

 
makes_carried resp_time_obj 
GMC   18000 
Ford    7200 
Cobalt   43200 
Chevrolet  18000 
Buick   18000 
Cadillac   7200

我需要得到如下的佈局（這顯然會按日期，LCAT分組）：

日期：

Date LCat LType #ofLds AvgResp #LdsRespOT %LdsRespOT #Lds!RespOT %Lds!RespOT 19-Jul GM Internet Sales 10 18 minutes 7 70% 3 30% 19-Jul GM Internet Service 20 20 minutes 10 50% 10 50% 19-Jul Handraiser Sales 10 45 minutes 5 50% 5 50% 20-Jul Dealer Web Sales 20 120 minutes 5 25% 15 75% 20-Jul Dealer Web Service 10 7 minutes 3 30% 7 70%

每一列，我需要說明 opportunities.date_entered =今日（此必須對課程的一切）

轉移酶： opp_cstm.lead_category

LTYPE：運p_cstm.lead_type

#ofLds：這就需要將其中刪除=機會伯爵「0」而導致分類不爲空

AvgResp：魅力。在機會timefollowup-C字段，其中已刪除=「0」和鉛類別不是null，和time_followup_c> 0並且不爲空的

#LdsRespOT： Count的機會，其中已刪除=「0」，並導致分類是不NULL和time_followup_c小於或等於resp_time_obj AND make_c = makes_carried和time_followup_c> 0並且不爲空

％LdsRespOT：（#LdsRespOT/#ofLds）

#Lds RespOT：（＃ ofLds - #LdsRespOT）

！210

％數據Lds RespOT：（！#Lds RespOT/#ofLds）

我有一個很難讓我的頭圍繞此查詢。我想知道這裏有人能否提供某種協助？我將如何正確寫這個查詢？

我已經嘗試了幾次，但每次都失敗，我感到沮喪！我知道我只是缺少一些某種類型的分組或某種我缺少的子查詢。

任何幫助將不勝感激！

謝謝！

任何人誰碰到這個，可能需要這樣的幫助來了，這裏是我落得這樣做：

SELECT 
opportunities.date_entered as Date, 
opportunities_cstm.lead_category_c as LCat, 
opportunities_cstm.lead_type_c as LType, 
count(opportunities.id) as '# of Lds', 
SUM(opportunities_cstm.time_followup_c)/count(opportunities.id) as AvgResp, 
SUM(
    CASE 
    WHEN ( 
     opportunities_cstm.time_followup_c IS NOT NULL 
     AND 
     opportunities_cstm.time_followup_c < leads_handling_objectives.resp_time_obj 
     ) 
    THEN 
     1 
    ELSE 
     0 
    END 
    ) as '#LdsRespOT', 
(SUM(
    CASE 
    WHEN ( 
     opportunities_cstm.time_followup_c IS NOT NULL 
     AND 
     opportunities_cstm.time_followup_c < leads_handling_objectives.resp_time_obj 
     ) 
    THEN 
     1 
    ELSE 
     0 
    END 
    ) /count(opportunities.id))*100 as '%LdsRespOT', 
count(opportunities.id) - SUM(
    CASE 
    WHEN ( 
     opportunities_cstm.time_followup_c IS NOT NULL 
     AND 
     opportunities_cstm.time_followup_c < leads_handling_objectives.resp_time_obj 
     ) 
    THEN 
     1 
    ELSE 
     0 
    END 
    )as '#Lds!RespOT', 
((count(opportunities.id) - SUM(
    CASE 
    WHEN ( 
     opportunities_cstm.time_followup_c IS NOT NULL 
     AND 
     opportunities_cstm.time_followup_c < leads_handling_objectives.resp_time_obj 
     ) 
    THEN 
     1 
    ELSE 
     0 
    END 
    ))/count(opportunities.id))*100 as '%Lds!RespOT' 
FROM 
opportunities 
INNER JOIN 
opportunities_cstm 
ON 
    opportunities_cstm.id_c = opportunities.id 
AND 
    opportunities_cstm.lead_category_c IS NOT NULL 
AND 
    opportunities_cstm.lead_category_c NOT LIKE '' 
INNER JOIN 
leads_handling_objectives 
ON 
    leads_handling_objectives.makes_carried = opportunities_cstm.make_c 
WHERE 
opportunities.date_entered = DATE(NOW()) 
AND 
opportunities.deleted='0' 
GROUP BY 
opportunities_cstm.lead_category_c
