Mysql查询返回类似的结果
collector amount name
1 0.00 gihan
1 2000.00 gihan
1 2500.00 gihan
1 11502.00 gihan
2 1140.00 lasita
我想得到像一样的结果数组
collector amount count name
1 16002.00 4 gihan
2 1140.00 1 lasita
知道如何循环结果集以获得匹配收集器的和，同时获得计数并将结果放入新数组中吗？
既然MySQL可以为你做这项工作，你为什么要在PHP中解决这个问题？
SELECT collector, sum(amount) as amount, count(*) as `count`, name
FROM yourTable
GROUP BY collector, name
SELECT collector,sum(amount) as amount,COUNT(*) as count,name
FROM Table
GROUP BY collector,name;
使用SUM和COUNT来获得直接结果。无需循环。
SELECT Collector,SUM(Amount) as Amount,COUNT(Amount) as Count,Name
FROM YourTable
GROUP BY Collector,Name
