Question

我对PHP / MySQL没有多少经验。我有一个包含3个字段的表格：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

我想分组显示数据以及每个组的总和，如下所示：

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

我尝试此查询SELECT SUM(amount), particular FROM sale_expense GROUP BY particular并添加了所有值，但它未显示在组中，因为我需要显示数据

Answer 1

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

Answer 2

试试这个sql：

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

这应该给你每组的总数。
更新：试试这个

$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 3

您可以将查询结合在一起：

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 4

试试这个：

( 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

在行组中显示结果并对每个组值求和
