I have 2 table with diferent data

I want to return diferent data like this:
+-------------------------+
| no_order | no_order |
+-------------------------+
| 1212121212 | 2222222222 |
+-------------------------+
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 table:
| staff_id | leader_id | team_role | importance |
+ + + + +
| 1001037 | 1000321 | HOD | 1 |
| 1001037 | 1000322 | HOD | 1 |
| 1001037 | 1001037 | Supervisor | 2 |
| 1001094 | 1001037 | Checker | 3 |
| 1001075 | 1001037 | Checker | 3 |
| 1001096 | 1001075 | Squad Leader | 4 |
| 1000393 | 1001094 | Squad Leader | 4 |
| 1000465 | 1001094 | Squad Leader | 4 |
| 1000585 | 1001075 | Squad Leader | 4 |
| 1000664 | 1000585 | Team Member | 5 |
| 1000583 | 1000585 | Team Member | 5 |
| 1000570 | 1000465 | Team Member | 5 |
| 1000316 | 1000465 | Team Member | 5 |
In php it look like this:
If I want to remove user with staff_id = 1001075 I need to remove all assigned to this user ids. So it will be ids where 1001075 is leader_id. I am able to this but I also need to remove users going down to the tree so where leader_id= 1001075 is will be 1000585 Then I need to remove users where leader_id= 1000585
In the end I need to delete these users with staff_id:
1001075
1001096
1000585
1000664
1000583
How can I do that?
There are two ways to do this:
Recursively query for all the ids to find out all the children and delete the rows one by one. Have a look at this answer for approaches to recursively query the ids.
Run an ALTER TABLE script and make leader_id a foreign key, referencing to staff_id of the same table, and define with ON DELETE CASCADE. By this way, when you delete a leader row, it will delete all the subsequent rows, e.g.:
ALTER TABLE table
ADD CONSTRAINT fk_leader_id FOREIGN KEY (leader_id) REFERENCES table(staff_id) ON DELETE CASCADE;
I would prefer the second approach.

i have a task to complete. there is a many to many relationship. the bridge table has been made which looks like
left id right id
+----------+---------+
| 1 | 1 |
| 1 | 2 |
| 2 | 1 |
| 2 | 2 |
| 2 | 8 |
| 3 | 1 |
| 3 | 2 |
| 3 | 4 |
| 4 | 1 |
| 4 | 2 |
| 4 | 3 |
| 4 | 5 |
| 5 | 1 |
| 5 | 2 |
| 5 | 4 |
| 5 | 6 |
| 5 | 7 |
+----------+---------+
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

Table1 - Payout Requests
`
|--------|-----------|-----------|
| id | Receiver | Balance |
|--------|-----------|-----------|
| 1 | user1 | 2000 |
|--------|-----------|-----------|
| 2 | user2 | 1500 |
|--------|-----------|-----------|`
Table2 - Donars
`
|--------|-----------|-----------|
| id | Donar | Amount |
|--------|-----------|-----------|
| 1 | love | 1500 |
|--------|-----------|-----------|
| 2 | don1 | 1000 |
|--------|-----------|-----------|`
Now my question; What piese of code will make Adjustments of both the tables so that data from these two tables goes in 3rd table in the following way
Table3 - Links
`
|--------|-----------|-----------|----------|
| id | Donar | Receiver | Amount |
|--------|-----------|-----------|----------|
| 1 | love | user1 | 1500 |
|--------|-----------|-----------|----------|
| 2 | don1 | user1 | 500 |
|--------|-----------|-----------|----------|
| 3 | don1 | user2 | 500 |
|--------|-----------|-----------|----------|`
AND now Table 1 & Table 2 will be Follows -
Table1 - Payout Requests
`
|--------|-----------|-----------|
| id | Receiver | Balance |
|--------|-----------|-----------|
| 2 | user2 | 1000 |
|--------|-----------|-----------|`
Table2 - Donars
`
|--------|-----------|-----------|
| id | Donar | Amount |
|--------|-----------|-----------|
| Nothing |
|--------|-----------|-----------|`
In the first step you should have a foreign key on Donars table which save id of Payout Requests. for example pr_id
You can use INNER JOIN like this:
SELECT `t2`.`id`, `t2`.`Donar`, `t1`.`Receiver `, `t1`.Balance - `t2`.`Amount` AS `Adjustment` FROM `table1` AS `t1` INNER JOIN `table2` AS `t2` ON `t2`.`pr_id` = `t1`.id

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.
