SUM分組COUNT的只有calaculate最大值和最大

的顯示計數我有6個領域的表：SUM分組COUNT的只有calaculate最大值和最大

partyname state  constituency  candidatename district votes 
    BJP  Maharashtra Nagpur-East  Nitin Gadkari Nagpur  1200 
    AAP  Maharashtra Nagpur-East  Arvind Kejriwal Nagpur  750 
    BJP  Maharashtra Nagpur-West  Vicky   Nagpur  4800 
    AAP  Maharashtra Nagpur-West  Lucky   Nagpur  3500 
    BJP  Maharashtra Nagpur-North Rakesh   Nagpur  100 
    AAP  Maharashtra Nagpur-North Ravan   Nagpur  1500

我想組partyname，選區與「計數」，行「SUM」

但它只計算每個選區的最大值，然後顯示計數和行總和。

下面是我期望的輸出上面表

partyname  Count 
    BJP   2 

    AAP   1

bcoz從那格浦爾-east和那格浦爾BJP引線西。所以它顯示計數2 和AAP從那格浦爾商機 - 北方則顯示只有1計數。

PLZ建議我詢問......

<?php 
$state = $rowdst['state']; 
$sqlst = "SELECT MAX(votes) AS Vote,constituency,state, district FROM voter_count where state = '$state' group by constituency, state"; 
$resultst = mysql_query($sqlst); 
while($rowst = mysql_fetch_array($resultst,MYSQL_ASSOC)) 
    { 
    ?> 
    <?php 
      $vote = $rowst['Vote']; 
      $sqlct = "SELECT COUNT($vote) AS counts,partyname,constituency, district FROM voter_count where votes = '$vote' AND state = '$state'"; 
      $resultct = mysql_query($sqlct); 
      $rowct = mysql_fetch_array($resultct,MYSQL_ASSOC) 
     ?>  
      <tr> 
       <td><?php echo $rowct['partyname']; ?></td> 
       <td><?php echo $rowct['counts']; ?></td> 
     </tr> 
<?php } ?>

我在結果集中看不到選區，注意PHP的mysql_ API早已棄用。 – Strawberry 2014-10-10 06:55:53

假設你不關心同樣的投票爲不同的黨派（處理同票同區計數各方將使查詢要複雜得多，因爲你會在內部查詢得到不可預料的值MAX列）：

所有的

SELECT RES.PARTYNAME, COUNT(RES.CONSTITUENCY) AS VOTESCOUNT 
FROM voter_count RES 
JOIN (
    SELECT CONSTITUENCY, MAX(VOTES) AS VOTES 
    FROM voter_count 
    GROUP BY CONSTITUENCY 
) MAXS USING(VOTES, CONSTITUENCY) 
GROUP BY PARTYNAME;

首先，內部查詢votes選擇最大值。內部查詢執行的結果爲：

Nagpur-East,1200 
Nagpur-North,1500 
Nagpur-West,4800

然後，加入最大值和計數區。

AAP,1 
BJP,2

如何從上面查詢這個計數和partname查詢我是新的php .plz sugget me ..... – 2014-10-10 07:52:31

正如你所做的那樣，結果中的列名是'PARTYNAME'和'VOTESCOUNT'。順便說一句，這個問題你貼的國家「PLZ建議我詢問。」 – mudasobwa 2014-10-10 08:01:13

SELECT RES.PARTYNAME，COUNT（RES.CONSTITUENCY）AS VOTESCOUNT FROM voter_count RES JOIN（ SELECT選區MAX（投票）是投票 FROM voter_count GROUP BY CONSTITUENCY ）MAXS USING（VOTES） GROUP BY PARTYNAME如何回顯上述查詢的輸出 – 2014-10-10 08:22:55

閱讀您的問題後，它很難理解你想要什麼作爲輸出結果

SELECT partyname AS 'Party Name',COUNT(candidatename) AS 'can_count',SUM(votes) AS 'sum' 
FROM voter_count 
WHERE votes >= 1500 
GROUP BY constituency 
ORDER BY can_count DESC;

還要檢查這個SQL Fiddle Link

希望此查詢可以幫助您獲得所需的輸出..

@mudasobwa WTF是WTF ?? – 2014-10-10 08:03:35

這是您的問題的解決方案..希望這會工作..

select t1.partyname as PARTY, count(*) as WinCount 
from voter_count t1, voter_count t2 where t1.votes > t2.votes 
and t1.constituency=t2.constituency 
group by t1.partyname
