Question

我有 fields-emp_id，rem_amount，rem_date 的数据库 dbadmin ，table - tbl_empreimburse 。

我想检索从给定日期到一周的数据。我试过这个查询，

SELECT SUM(rem_amount),DATEADD(dd, -7, "2012-01-10")  
FROM tbl_empreimburse 
GROUP BY emp_id 
HAVING emp_id='5' AND rem_date BETWEEN DATEADD(dd, -7, "2012-01-10") AND "2012-01-10"

它给出了错误“功能dbadmin.DATEADD不存在”。我需要将“2012-01-10”转换为日期格式吗？请帮忙吗？

Answer 1

试试这个：

此查询提供的结果为您为员工ID 5和日期7天指定的结果。

SELECT emp_id, SUM(rem_amount) 
FROM tbl_empreimburse 
WHERE emp_id='5' AND DATEDIFF('2012-12-31', rem_date) BETWEEN 0 AND 7;

或

以下查询为您提供所有员工数据。

SELECT emp_id, SUM(rem_amount) 
FROM tbl_empreimburse 
GROUP BY emp_id 
HAVING DATEDIFF('2012-12-31', rem_date) BETWEEN 0 AND 7;

Answer 2

检查*SQLFIDDLE reference out。：）

我不确定你为什么在这里使用group by条款......

样本日期：

ID  AMOUNT  RDATE
1   3400    January, 01 2012 00:00:00+0000
2   5000    January, 10 2012 00:00:00+0000
3   3000    January, 02 2012 00:00:00+0000
5   1000    January, 05 2012 00:00:00+0000
5   2000    January, 04 2012 00:00:00+0000
2   2000    February, 10 2012 00:00:00+0000

查询：

select * from emp
where id = 5;

这是获得总和的查询

select id, sum(amount)
from emp
where rdate between '2012-01-10' - interval 7 day
and '2012-01-10'
and id = 5
;

结果： 员工ID = 5

的所有记录

ID  AMOUNT  RDATE
5   1000    January, 05 2012 00:00:00+0000
5   2000    January, 04 2012 00:00:00+0000

员工ID = 5

的金额总和

ID  SUM(AMOUNT)
5   3000

从表中获取给定日期和1周之间的日期数据
