i want group by GROUP(Horizontal nit vertical like table above) return the table like :

canc 5 3 2
inst 3 1 2
new 2 2 0
prod 3 1 2
ret 4 2 2
toRet 2 2 0
There is no easy way to do this in Mysql query. you will have to use case statement and manually convert the rows in to columns. Still you will have to know all possible combinations
select sum(case when Groupe = 10 then Groupe else 0 end ) as Grp_10,
...
...
from ...
Otherwise you may export the results to a CSV and do the necessary pivoting in spreadsheet software like excel

I'm very inexperienced. I've prepared a select statement which gives the information I need to populate a matches table. However it is not suitable because it contains a where clause. Is there a different way to use it, or how can I change it so that it is suitable for INSERT INTO.
The tables are as follows:-
match_order
match_order_id||match_descrip||first_player||second_player
1 1v2 1 2
2 1v3 1 3
3 2v3 2 3
4 1v4 1 4
5 2v4 2 4
6 3v4 3 4
entries
entry_id||round_id||league_id||box_id||box_position
1 1 1 1 1
2 1 1 1 2
3 1 1 1 3
4 1 2 1 4
5 1 2 1 2
6 1 2 1 1
7 1 2 1 1
matches
match_id||round_id||league_id||box_id||match_order_id||player1||player2
I need to insert new rows every month for a new round of matches. League size, box size & positions change each month.
This is the statement which gives the correct rows.
SELECT e.round_id, e.league_id, e.box_id, mo.match_order_id, e.entry_id as player1, e1.entry_id as player2
FROM match_order mo
LEFT JOIN entries e ON mo.first_player = e.box_position
LEFT JOIN entries e1 ON mo.second_player = e1.box_position
WHERE e.round_id = e1.round_id AND e.league_id = e1.league_id AND e.box_id = e1.box_id
ORDER BY round_id, league_id, box_id, match_order_id
Any help & advise would be greatly appreciated.
Thank you
Assuming match_id is an auto-increment column, you have the data for the other columns. You can just add the INSERT statement before your SELECT.
INSERT INTO matches(round_id, leage_id, box_id, match_order_id, player1, player2)
SELECT e.round_id, e.league_id, e.box_id, mo.match_order_id, e.entry_id as player1, e1.entry_id as player2
FROM match_order mo
LEFT JOIN entries e ON mo.first_player = e.box_position
LEFT JOIN entries e1 ON mo.second_player = e1.box_position
WHERE e.round_id = e1.round_id AND e.league_id = e1.league_id AND e.box_id = e1.box_id
I have the following database tables.
my_left_table
left_id name
1 A
2 B
3 C
my_right_tabe
right_id thing left_id_fk status
1 D 1 new
2 E 1 new
3 F 2 old
4 G 3 old
5 H 3 new
6 I 3 new
7 J 1 old
8 K 2 old
9 L 2 new
10 M 3 old
11 N 3 old
12 O 1 new
My desired result is as follow.
my_left_table
left_id name
3 C
How do I select the left records which its right records have AT LEAST 2 status is new AND 2 status is old. For example, left_id 1 is not the target because three of its right records have the status new but only one record has the status old.
So far I have is.
SELECT *, COUNT(my_right_tabe.left_id_fk) AS count_left_id_fk
FROM my_left_table
INNER JOIN my_right_tabe
ON my_left_table.id = my_right_tabe.left_id_fk
GROUP BY my_right_tabe.left_id_fk
Use the HAVING clause in MySQL
Like the following
SELECT my_left_table.left_id, my_left_table.name
FROM my_left_table
INNER JOIN my_right_tabe
ON my_left_table.left_id = my_right_tabe.left_id_fk
GROUP BY my_right_tabe.left_id_fk
HAVING SUM(my_right_tabe.status="new") >= 2 AND
SUM(my_right_tabe.status="old") >= 2
You can achieve desired results by first grouping the values and then check its total. If its >= 2 pull that record.
Here is the query
SELECT z.*
FROM
(
SELECT a.left_id, name, status, IF(COUNT(*) >=2, 1, 0) AS status_calc
FROM my_left_table a JOIN my_right_table b
ON a.left_id = b.left_id_fk
GROUP BY left_id, status
) z
GROUP BY z.left_id
HAVING SUM(status_calc) = 2;
Working Demo
Considering the following query:
SELECT t.recording_id, m.release_id
FROM track t
JOIN medium m ON t.medium_id = m.medium_id
i get a result set similar to this one
recording id release id
----------------------------------
1 25
1 25
1 37
1 76
1 300
1 336
2 37
... ...
i need to output the following
recording id count
---------------------------------------------------
1 5
2 1
In other words, i need to group by the recording_id but not count the release_id duplicates for that recording_id
After researching this board i've tried the following, with no success :
SELECT t.recording_id, count(t.recording_id)
FROM track t
JOIN medium m ON t.medium_id = m.medium_id
group by t.recording_id, m.release_id
but, im getting
recording id release id
--------------------------
1 2
1 1
1 1
1 1
1 1
2 1
What's wrong?
Try this, you can use distinct in your count function to return distinct release ids for a recording_id
SELECT t.recording_id, count(distinct m.release_id) cnt
FROM track t
JOIN medium m ON t.medium_id = m.medium_id
group by t.recording_id
I'm trying to make a select with percetaje average. These are my tables:
tb_module
ID_MOD MODULE ID_PR
1 Module 1 1
2 Module 2 1
3 Module 3 2
tb_activity
ID_ACT ID_MOD ACTIVITY
1 1 Activity 1.1
2 1 Activity 1.2
3 2 Activity 2.1
4 2 Activity 2.2
tb_percentaje
ID_PERC ID_ACT PERCENTAJE
1 1 20
2 2 10
3 3 70
4 4 50
One of my QUERYS is like this----> WHERE ID_PRO = 1 ( when module has activity(ies) ) :
ID_MOD MODULE AVG(PERCENTAJE)
1 Module 1 15
2 Module 2 60
But, when module doesn't have activity(ies) ------> WHERE ID_PRO = 2. Query returns 0 rows.
How can i fix this issue?
Should be like this, WHERE ID_PRO = 2
ID_MOD MODULE AVG(PERCENTAJE)
3 Module 3 0
'0' because doesn't have activity.
Try this:
SELECT m.ID_MOD, m.MODULE, AVG(p.PERCENTAJE)
FROM tb_module m
LEFT JOIN tb_activity a ON m.ID_MOD = a.ID_MOD
LEFT JOIN tb_percentaje p ON a.ID_ACT = p.ID_ACT
WHERE m.ID_PRO = 2
GROUP BY m.ID_MOD
I have the following 2 tables:
1) Companies
ID CompanyName Abbreviation Notes
1 CompanyA CA ...
2 CompanyB CB ...
3 CompanyC CC ...
2) PlannedDeployments
ID CompanyID TypeID DepDate NumDeployed
1 1 2 09/2010 5
2 1 2 10/2010 5
3 1 3 09/2010 3
4 1 3 10/2010 3
5 1 4 10/2010 4
6 2 2 12/2010 10
7 2 4 10/2010 1
8 3 2 11/2010 6
Note that TypeID is a number between 1 and 5 describing what type of person is being deployed. For the purposes of this query, I'm interested in Type2 employees for each company and then the sum of Types 3 & 4 for each date. What I eventually want to end up with is a crosstab that looks like the following:
Crosstab
Date/Company CompanyA CompanyB CompanyC SumOfTypes3and4
09/2010 5 3
10/2010 5 8
11/2010 6
12/2010 10
The problem is that final column - the sum of Type 3 and Type 4 employees. The current crosstab that I have includes everything except that sum column and looks like the following:
TRANSFORM Sum(PlannedDeployments.NumDeployed) AS ["NumDeployed"]
SELECT PlannedDeployments.DepDate
FROM PlannedDeployments LEFT JOIN Companies ON Companies.ID=PlannedDeployments.CompanyID
WHERE PlannedDeployments.TypeID=2 AND (PlannedDeployments.DepDate Between FormFieldValue("Form", "Control") AND FormFieldValue("Form", "Control"))
GROUP BY PlannedDeployments.DepDate
PIVOT Companies.CompanyName;
The second part of that WHERE clause is just limiting the data by some form controls. Anyway - I'm having a lot of trouble getting that final column. Anyone have any ideas?
Edit: Building on the solution provided by Remou below, here's what the final query ended up looking like:
TRANSFORM Sum(PlannedDeployments.NumDeployed) AS ["NumDeployed"]
SELECT PlannedDeployments.DepDate, q.SumOfNumDeployed
FROM (SELECT PlannedDeployments.DepDate, Sum(PlannedDeployments.NumDeployed) AS SumOfNumDeployed
FROM PlannedDeployments
WHERE (((PlannedDeployments.[TypeID]) In (3,4)))
GROUP BY PlannedDeployments.DepDate) AS q
RIGHT JOIN (PlannedDeployments
INNER JOIN Companies ON PlannedDeployments.CompanyID = Companies.ID)
ON q.DepDate = PlannedDeployments.DepDate
WHERE PlannedDeployments.TypeID=2
AND (PlannedDeployments.DepDate Between FormFieldValue("Form", "Control")
AND FormFieldValue("Form", "Control"))
GROUP BY PlannedDeployments.DepDate, q.SumOfNumDeployed
PIVOT Companies.CompanyName;
You can use a subquery:
TRANSFORM Sum(PlannedDeployments.NumDeployed) AS ["NumDeployed"]
SELECT PlannedDeployments.DepDate, Sum(q.SumOfNumDeployed) AS SumOfSumOfNumDeployed
FROM (SELECT PlannedDeployments.DepDate, Sum(PlannedDeployments.NumDeployed) AS SumOfNumDeployed
FROM PlannedDeployments
WHERE (((PlannedDeployments.[TypeID]) In (3,4)))
GROUP BY PlannedDeployments.DepDate) AS q
RIGHT JOIN (PlannedDeployments
INNER JOIN Companies ON PlannedDeployments.CompanyID = Companies.ID)
ON q.DepDate = PlannedDeployments.DepDate
WHERE PlannedDeployments.TypeID=2
AND (PlannedDeployments.DepDate Between FormFieldValue("Form", "Control")
AND FormFieldValue("Form", "Control"))
GROUP BY PlannedDeployments.DepDate
PIVOT Companies.CompanyName;
