I have Document with field: _id, title, one, two, positionOne, positionTwo
For example:
_id | title | one | two | positionOne | positionTwo
1 | aaa | 12,2| 10 | |
2 | bbb | 3,2 | 12,2| |
3 | ccc | 12,6| 2 | |
4 | ddd | 3 | 4 | |
5 | eee | 5,5 | 5 | |
And I would like receive:
_id | title | one | two | positionOne | positionTwo
1 | aaa | 12,2| 10 | 2 | 3
2 | bbb | 3 | 12,2| 4 | 2
3 | ccc | 12,6| 2 | 1 | 5
4 | ddd | 3 | 4 | 4 | 4
5 | eee | 5,5 | 15 | 3 | 1
I would like add positions from max to min.
Is this possible only with Mongo queries to db?

I'm trying to recreate simple SQL query in DAX. The output Query needs to work in Power BI Report Builder and I have been trying all day reading all sorts of PowerBI / DAX online resources to rewrite this.
A little bit about the data:
The data is structured in three tables, CustomCar, Engine and Chassis.
Basically "CarId" is the key that connects all three tables.
Let's assume all tables have more than 20 columns. so only a few of the columns are needed in the final output.
All three tables (CustomCar, Chassis and Engine) have an IsActive property (the relationship between Engine/Chassis to CustomCar is MANY-TO-ONE. Because an engine might blow up and they change it therefore somehow we want to track which Engine is on the car today and what engine was on it last year, however, at any time, there is only one active engine for each car.. The same goes for Chassis)
Both Engine and Chassis have 'Manufacturer' and 'Model' columns so in the output query they need to be identified from each other.
I am not trying to sum any sort of sales number, just a list of cars with their current configuration.
Any help is appreciated.
Select
CC.Name, CC.Model as 'CustomCarModel', CC.MaxSpeed,
Ch.Manufacturer as 'ChassisManufacturer', Ch.Model as 'ChassisModel', Ch.ManufacturedDate as 'ChassisManfDate',
E.Manufactuer as 'EngineManufacturer', E.Model as 'EngineModel', E.Power, E.CylCount, E.ManufacturedDate
From CustomCars CC
Join Chassis Ch on Ch.CarID = CC.CarId
Join Engine E on E.CarID = CC.CarID
where
CC.IsActive = 1 and CC.FirstTestDriveYear < 1980 and
Ch.IsActive = 1 and
E.IsActive = 1
More info, here are my tables.
Classic Car:
CarId (Primary Key) | Model | MaxSpeed | NumOfPax | TankCapacity | IsActive | FirstTestDriveYear |....
1 | SuperChev | 220 | 2 | 60 | 1 | 1985 |
2 | CustomBranco | 185 | 2 | 90 | 1 | 1979 |
3 | RebuiltToyo | 251 | 4 | 20 | 0 | 1990 |
Chassis:

2 | 1 | 1 | SuperChassis | T5 | '03-Feb-1987' | ...

I have found a work around for this. I added the query when adding the data pipeline in Power BI dashboard and will use the values from the query as is.
i need help with counting some data

i really need it for create some research about second action from users
how do i do it?
thank you
Using ROW_NUMBER should work here:
SELECT
user_id,
action_id,
ROW_NUMBER() OVER (PARTITION BY action_id ORDER BY user_id) count
FROM yourTable
ORDER BY
user_id;

I have 2 tables:
Table1: 'op_ats'
| ID1 | numero |id_cofre | id_chave | estadoAT
| 1 | 111 | 1 | 3 | 1
| 2 | 222 | 3 | 3 | 2
| 3 | 333 | 1 | 4 | 2
| 4 | 444 | 1 | 2 | 3
Table_2: 'op_ats_cofres_chaves'
| ID2 | num_chave |
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | E |
I have this SQL:
SELECT chaves.*, ats.numero numAT, ats.estadoAT
FROM op_ats_cofres_chaves chaves
LEFT JOIN op_ats ats ON ats.id_chave_cofre = chaves.id AND ats.id_cofre = 1
With this I get the following result:
| ID2 | num_chave | numAT | estadoAT |
| 1 | A | 444 | 3 |
| 2 | B | NULL | NULL |
| 3 | C | 111 | 1 |
| 4 | D | 333 | 2 |
| 5 | E | NULL | NULL |
Now the problem is that I want to filter the rows that are in Table1 but only that have the column 'estadoAT' with values 1 and 2. I've tried to add the line
WHERE op_ats.estadoAT = 1 OR op_ats.estadoAT = 2
But this makes the following result:
| ID2 | num_chave | numAT | estadoAT |
| 1 | A | 444 | 3 |
| 3 | C | 111 | 1 |
| 4 | D | 333 | 2 |
Resuming...
My intention is to get ALL rows in the Table2 and join the Table1 rows that have the 'id_cofre = 1' and '(estadoAT = 1 OR estadoAT = 2)'.
Any help is appreciated.
You have to move condition to JOIN clause instead of WHERE.
SELECT chaves.*, ats.numero numAT, ats.estadoAT
FROM op_ats_cofres_chaves chaves
LEFT JOIN op_ats ats ON ats.id_chave_cofre = chaves.id AND ats.id_cofre = 1
AND op_ats.estadoAT = 1 OR op_ats.estadoAT = 2;
I have a table Members(id, name, parent_id), where parent_id is the parent of the member(it is also a member which can have its parent). For example
id | name | parent_id
----------------------
1 | John | NULL
2 | Smith| 1
3 | Andy | 1
4 | Joe | 2
5 | Rick | 2
6 | Craig| 5
7 | Greg | NULL
8 | Bob | 5
9 | Mike | 8
And I'd like to run statement select from members, and I want to have
id | name | parent_id | root_parent_id
--------------------------------------
1 | John | NULL | NULL
2 | Smith| 1 | 1
3 | Andy | 1 | 1
4 | Joe | 2 | 1
5 | Rick | 2 | 1
6 | Craig| 5 | 1
7 | Greg | NULL | NULL
8 | Bob | 7 | 7
9 | Mike | 8 | 7
I want to find the root_parent_id for all members as deeply as possible. Help me please
with recursive recursive_members as (
select *, id root_id, 1 depth
from members
union all
select r.id, r.name, r.parent_id, m.parent_id, r.depth+ 1
from recursive_members r
join members m on r.root_id = m.id
where m.parent_id notnull
)
select distinct on (id) *
from recursive_members
order by id, depth desc;
id | name | parent_id | root_id | depth
----+-------+-----------+---------+-------
1 | John | | 1 | 1
2 | Smith | 1 | 1 | 2
3 | Andy | 1 | 1 | 2
4 | Joe | 2 | 1 | 3
5 | Rick | 2 | 1 | 3
6 | Craig | 5 | 1 | 4
7 | Greg | | 7 | 1
8 | Bob | 5 | 1 | 4

Read about recursive WITH queries.
i would like to use the current row number of my org table in cell calculations, either in relation to the table as a whole or in relation to an hline.
if i have the following table:
|---+---+---|
| x | y | z |
|---+---+---|
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
| 2 | 4 | 8 |
|---+---+---|
#+TBLFM: #II..#III$1=2::$2=4::$3=$1*$2
how do I change it so that the in the y column each cell is equal to its table row number, as shown if you turn on grid mode in org? the resulting table would look like:
|---+----+----|
| x | y | z |
|---+----+----|
| 2 | 2 | 4 |
| 2 | 3 | 6 |
| 2 | 4 | 8 |
| 2 | 5 | 10 |
| 2 | 6 | 12 |
| 2 | 7 | 14 |
| 2 | 8 | 16 |
| 2 | 9 | 18 |
| 2 | 10 | 20 |
