我有两张桌子
表:交易
id . user_id . amount . status
1 - - 100 -- --- 500 - ----- 1
2 - - 100 -- --- 100 - ----- 0
3 - - 110 -- --- 200 - ----- 1
表:活动
id . user_id . bid . status . budget . expense . size
1 -- 100 ---- 80 --- 1 ------- 200 ------ 200 ---- 5 --
2 -- 109 ---- 75 --- 1 ------- 050 ------ 030 ---- 2 --
3 -- 100 ---- 65 --- 1 ------- 700 ------ 065 ---- 2 --
4 -- 107 ---- 77 --- 0 ------- 020 ------ 020 ---- 2 --
5 -- 90 ----- 87 --- 1 ------- 120 ------ 090 ---- 7 --
我需要使用 php 和 mysql 过滤后的campaign.id
条件:如果从用户那里收到的总金额/交易大于用户的总支出。钱也是批准的钱(1=批准,0=待定)。广告系列在方式 1 上,谁提出了最高出价
(sum(transaction.amount) WHERE transaction.status = 1 of that any user) > sum(campaign.expense of that user)
出价 = 最高(出价)
营地状态 = 1
1步解决方案
mysql_query("SELECT campaign.* FROM campaign c,transaction t
WHERE budget>expense AND status='1' AND size='2'
ON c.user_id=t.user_id
HAVING SUM (CASE WHEN transaction.status=1 THEN transaction.amount ELSE 0 END) > SUM(campaign.expense)"));
不工作
或者,如果有 3 个步骤中的任何解决方案 -
第一步
mysql_query("SELECT id,user_id FROM campaign
WHERE budget>expense AND status='1' AND size='2'")
第二步
keep id,user_id of 1st step WHERE SUM(transaction.amount status=1)
> SUM(campaign.expense)
第三步
mysql_query("SELECT id,user_id FROM campaign
WHERE step2 satisfied")
请帮忙,解决后我会睡觉
