顯示結果行組和總和各組值

Question

我對PHP/MySQL沒有太多經驗。我有一個有3個字段的表格：id,particular和amount，如下所示。

id particular amount 
1 Fees   5000 
2 Fees   3000 
3 Bill   9000 
4 Fees   4000 
5 Bill   3000 
6 Expense  2000 
7 Fees   1000 

我要顯示在組中的數據以及每個單獨組的總和，就像這樣：

particular amount 
Fees   5000 
Fees   3000 
Fees   4000 
Fees   1000 
**Total  13000** 
Bill   9000 
Bill   3000 
**Total  12000** 
Expense  2000 
**Total  2000** 

我嘗試此查詢SELECT SUM(amount), particular FROM sale_expense GROUP BY particular，並添加了所有的值，但它是該組中沒有顯示，因爲我需要顯示數據

Answer 1

嘗試這個SQL：

 
SELECT particular, SUM(amount) AS total FROM tablename GROUP BY particular 

這應該會給你每組的總數。
UPDATE： 試試這個

$sql = "SELECT particular, SUM(amount) AS total FROM tablename GROUP BY particular"; 
$result = mysql_query($sql); 
while($row = mysql_fetch_array($result)){ 
    $sql2 = "SELECT * FROM tablename WHERE particular = '".$row['particular']."'"; 
    $result2 = mysql_query($sql2); 
    while($row2 = mysql_fetch_array($result2)){ 
     echo $row2['particular']. " ".$row['amount']; 
     echo "\n"; 
    } 
    echo "Totol: ".$row['total'].""; 
}

Answer 2

可以聯合查詢一起：

select particular, amount 
from ((select id, particular, amount 
     from sales_expense se 
    ) union all 
     (select 99999 as id, concat('Total: ', particular), sum(amount) as amount 
     from sales_expense se 
     group by particular 
    ) 
    ) t 
group by particular 
order by id 

Answer 3

試試這個：

(SELECT 
    particular, 
    amount 
    FROM sale_expense) 
UNION 
(SELECT 
    CONCAT(particular," - total") AS particular, 
    SUM(amount) AS amount 
    FROM sale_expense 
    GROUP BY particular) 
ORDER BY particular ASC 

Answer 4

SELECT particular, id, sum(amount) amount 
FROM TableName 
GROUP BY particular, id WITH ROLLUP
