Maybe you need in simple
SELECT t1.no_order, t2.no_order
FROM Finance t1
JOIN Orderan t2 ON t1.id = t2.id
WHERE t1.no_order != t2.no_order
?
I have a search page that allow user to key in the member ID and it will list out all the downline that belongs to the user.
I am using easyui treegrid to generate the downline.
Now i need to do an extra button to export out all the downline that belongs to the search id and export each line of information into excel file.
This is part of my data, and actually the real data had more column and about 4000++ of data.
Is there anyone can help me or some references? Please let me know if you need more info
+-------------+---------------+---------------------------+------------+
| MemberID | parent_id | Name | Age |

| 1 | 0 | Cassy | 8 |
| 2 | 1 | Peter | 7 |

for left id 1
left1 | right1 righ 2
for left id 3
left3 | right1 right2 right 4
how do i do this ? i have tried joining table , doesn't work
I think you can use a simple query to acheive this using GROUP BY and GROUP_CONCAT()
SELECT left_id, GROUP_CONCAT(right_id SEPARATOR ' ') as rigth_id
FROM left-right
GROUP BY left_id;
This is a reasonably straightforward application of GROUP_CONCAT() and GROUP BY. (http://sqlfiddle.com/#!9/ed7e1/2/0)
SELECT leftId,
GROUP_CONCAT(rightId ORDER BY rightId) rightIds
FROM bridge
GROUP BY leftId

You can do it with SQL FOREIGN KEY Constraint on ALTER TABLE. You can see the documentation here.
ALTER TABLE first_table_name
ADD FOREIGN KEY (id)
REFERENCES second_table_name(CUSTOMER_ID)
It should work.

This id my table :

+------------+--------------+---------------------+--------+
| 129 | 00:00:00 | 2014-01-19 04:08:00 | 1 |
| 190 | NULL | 2014-01-19 02:20:34 | 6 |
| 1390228962 | NULL | 2014-01-19 02:09:20 | 4 |

| 151 | NULL | 2014-01-19 01:06:01 | 7 |
| 195 | NULL | 2014-01-15 01:10:00 | 2 |
+------------+--------------+---------------------+--------+
and i want to get row id = 1390228963 when I search for time = 2014-01-19 02:07:00
I thought that I have been explained it good
You need to get the last row before the time:
select t.*
from table t
where time <= '2014-01-19 02:07:00'
order by time desc
limit 1;
Just use this mysql query
SELECT * from tablename where time="2014-01-19 02:00:11";
