Question

帐户表

 user_id   description    credit  debit    created      modified
    01        Earned        10      0    06-11-2013     06-11-2013 
    02        Normal        0       1    05-11-2013     05-11-2013      
    03        Earned        5       0    04-11-2013     04-11-2013  
    04        Earned        20      0    03-11-2013     03-11-2013      
    05        Normal        0       1    02-11-2013     02-11-2013  
    01        Earned        5       0    02-11-2013     02-11-2013
    01        Normal        0       1    01-11-2013     01-11-2013
    02        Earned        10      0    01-11-2013     01-11-2013

我尝试了以下查询：

SELECT SUM(CASE WHEN description LIKE  '%Earned%'
THEN Credit
ELSE 0 
END ) as cre, SUM(debit) as deb FROM accounts
WHERE created is between '$Monday' AND '$Sunday'

INSERT into accounts (user_id, description, credit, debit, created, modified) 
VALUES ( 'user_id', 'Removed Free Earned', 'cre', 'deb', Now(), Now());

我想根据用户选择账户表和汇总信用卡和汇款借方，例如，如果user_id 01总信用额为10，则上周一至周日的借方总金额是3然后应在“deb”的“插入查询”位置添加7个点。但如果总信用额度为10且总借方为20，那么如果借方大于贷方，则不会增加任何积分。

我希望Select和Insert Query应该写成一个查询。

Answer 1

您可以使用以下查询

INSERT into newaccounts (user_id, description, credit, debit, created, modified) 
SELECT user_id,description,
SUM(CASE WHEN 
description = 'Earned' 
THEN credit 
ELSE 0 
END) cre,
SUM(debit) as deb,NOW(),NOW() 
FROM accounts 
WHERE created between '03-11-2013' AND '04-11-2013';

Answer 2

您可以使用MySQL的insert select语法。

INSERT INTO accounts (col1, col2) SELECT col1, (expr) AS col2 FROM accounts

在一个查询中选择并插入查询？
