+------------+--------------+---------------------+--------+
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";

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 to display the left id = right id in one row
for example
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.

Hi, I'm trying to transfer the body_value column into the html column and am not sure how to execute this. I have a table called i_posts and I have all the id's of my posts that i'm trying to transfer. However in the field_data_body table it doesn't have content for every single entry_id. Is there a way to move the body_value into the html column while keeping the correct id? Thanks for any help in advanced!!
- Blake
Edit:
This is what you need.
UPDATE i_posts AS i, field_data_body AS f SET i.html = f.body_value WHERE i.id =f.entry_id
I did a small post about it.
