I have a table in which i have four columns
id
user_type
user_role
org_id
Now if the user_type is 1 (i.e individual) then the user_role and org_id will be null,
but if the user_type is 2 (i.e organisation) then it will have org_id (id of the organisation) and user_role (his role in the organisation).
There are three type of role in an organisation
admin (only one person could be the admin).
finance secrearty (could be more than one).
approvers (also could be more than one).
What I want
I want to fetch only one person (probably admin of the organisation) if the user_type is 2 from each organisation and all the users having user_type 1.
My table
-------------------------------------
| tbl_user |
-------------------------------------
| id | user_Type | user_role | org_id|
--------------------------------------
| 1 | 1 | null | null |
| 2 | 2 | 1 | 1 |
| 3 | 2 | 2 | 1 |
| 4 | 2 | 3 | 1 |
| 5 | 2 | 3 | 1 |
| 6 | 1 | null | null |
| 7 | 2 | 1 | 2 |
| 8 | 2 | 2 | 2 |
| 9 | 2 | 3 | 2 |
| 10 | 2 | 3 | 2 |
by using query
SELECT * FROM YourTable t
WHERE t.user_type = 1
OR t.user_role = 1
Expected result
-------------------------------------
| tbl_user |
-------------------------------------
| id | user_Type | user_role | org_id|
--------------------------------------
| 1 | 1 | null | null |
| 2 | 2 | 1 | 1 |
| 7 | 2 | 1 | 2 |
| 6 | 1 | null | null |
Then i have to join the result with tbl_user_meta with (where zipcode = 85225).
My tbl_user_meta follows-
-------------------------------------
| tbl_user_meta |
--------------------------------------
| id | uid | user_name | zipcode|
--------------------------------------
| 1 | 1 | abc | 85225 |
| 2 | 2 | asd | 85225 |
| 3 | 3 | asd | 85225 |
| 4 | 4 | sdf | 345678 |
| 5 | 5 | fgd | 23456 |
| 6 | 6 | rgy | 23567 |
| 7 | 7 | hyt | 12345 |
| 8 | 8 | ukl | 12345 |
| 9 | 9 | tko | 21334 |
| 10 | 10 | ert | 85225 |
What i finally want to achieve is this record
-------------------------------------
| tbl_user_meta |
--------------------------------------
| id | uid | user_name | zipcode|
--------------------------------------
| 1 | 1 | abc | 85225 |
P.S - I am doing this with codeigniter
Thanks.
you can join the table as under remember remove "" from "85225" if it is integer.
select * from tbl_user, tbl_user_meta where tbl_user.id = tbl_user_meta.id AND tbl_user_meta.zipcode = "85225";
select a.id, a.uid, b.username, a.zipcode
from tbl_user_meta a
inner join tbl_user b
where a.uid = b.id ;
This can be achieved like this in codeigniter.
public function gettable(){
$query ='select a.id, a.uid, b.username, a.zipcode
from tbl_user_meta a
inner join tbl_user b
on a.uid = b.id
where a.zipcode = 85225';
$query = $this->db->query($query);
$result = $query->result();
return $result;
}
I think I have my answer:
$this->db->select('tbl_user.*,tbl_user_meta.*');
$this->db->from('tbl_user');
$this->db->where('user_type', 1);
$this->db->or_where('user_role', 1);
$this->db->where('tbl_user_meta.zipcode',85225);
$this->db->join('tbl_user_meta','tbl_user_meta.did=tbl_user.id');
$query=$this->db->get();
return $query->result();

I have 3 tables:
table_1:
| id | test |total_employee|
+----+------+--------------+
| 1 | xxxx | 3 |
| 2 | yyyy | 2 |
| 3 | zzzz | 3 |
----------------------------
table_2:
| id | id_table1 |id_employee|
+----+-----------+-----------+
| 1 | 1 | 1 |
| 2 | 1 | 2 |
| 3 | 1 | 3 |
| 4 | 1 | 1 |
| 5 | 1 | 2 |
| 6 | 1 | 1 |
| 7 | 1 | 2 |
| 8 | 1 | 3 |
-----------------------------
table employee:
| id | name |
+----+------+
| 1 | emp1 |
| 2 | emp2 |
| 3 | emp3 |
-------------
and now I want to display all employees from table employee and from table_2 if the employee record in table employee exists but in table_2 it does not. If record does not exist mark as "unchecked" but if exists mark as "checked".
The point is how to find data from table_employee no matter data is exist or not exist on table_2.
The IF() operation lets you do this:
SELECT e.*, IF(ISNULL(t2.id), 'unchecked', 'checked') AS `checked`
FROM table_employee e
LEFT JOIN table_2 t2 ON t2.id_employee = e.id
I get form db field (organisations.paths)the following strings:
/1/2/3/4
Each number is the id of organisation's name from this db table:
+----+-------------+----------+----------+----------------------+
| id | frameworkid | path | parentid | fullname |
+----+-------------+----------+----------+----------------------+
| 1 | 1 | /1 | 0 | NYC University |
| 2 | 1 | /2 | 0 | Board of directors |
| 3 | 1 | /1/2/3 | 1 | Math faculty |
| 4 | 1 | /1/2/3/4 | 3 | Statistic department |
| 5 | 1 | /1/2/3/5 | 2 | Linguist department |
+----+-------------+----------+----------+----------------------+
Then I have the description table for each organisation:
+----+----------+---------+----------------+
| id | data | fieldid | organisationid |
+----+----------+---------+----------------+
| 1 | HQ | 1 | 1 |
| 2 | advisory | 1 | 2 |
| 3 | advisory | 1 | 3 |
| 4 | bottom | 1 | 4 |
| 5 | advisory | 1 | 5 |
+----+----------+---------+----------------+
How to join the both description table and main table and loop only through organisations, which have HQ or advisory in their description? So it becomes:
NYC University, Board of directors, Math faculty (Statistic department-won't be shown, as it is with description bottom)
You need to use explode, IN and join Function of PHP and mysql.
$var = "/1/2/3/4";
$in = join(" , ", explode("/", ltrim($var, '/')));
$sql = "SELECT `dt`.`fullname` FROM `db_table` dt
LEFT JOIN `organization` o
ON `o`.`organisationid` = `dt`.`id`
WHERE `o`.`id` IN ($in) AND (`o`.`data` = 'HQ' OR `o`.`data` = 'advisory')";
Make a loop to get the names and show them as you want.
I have a user and pages table, and these two have many to many relationship between them with the bridge table user privileges. What I want to get all the pages name and only those are marked that is assigned to that user.
want some think like this
+---------+----------------------------------+
| user_id | page_name | Assigned|
+---------+----------------------------------+
| 1 | Add Project | 0 |
| 1 | Department | 0 |
| 1 | Category | 1 |
| 1 | Item | 0 |
| 1 | Units | 1 |
| 1 | Stock In | 0 |
| 1 | Stock Card Report | 1 |
+---------+------------------------+---------|
for now my query is this;
Select up.user_id, p.page_name FROM user_privileges up, pages p where p.page_id = up.page_id and up.user_id = 1;
and it returns this;
+---------+------------------------+
| user_id | page_name |
+---------+------------------------+
| 1 | Add Project |
| 1 | Department |
| 1 | Category |
| 1 | Item |
| 1 | Units |
| 1 | Stock In |
| 1 | Stock Card Report |
+---------+------------------------+
The Scheme is this;
table - user
+---------+-----------+
| user_id | user_name |
+---------+-----------+
| 4 | saif |
| 1 | admin |
| 5 | taqi |
| 2 | rashid |
+---------+-----------+
table - pages
+---------+---------------+
| page_id | page_name |
+---------+---------------+
| 2 | Page 1 |
| 3 | Page 2 |
| 5 | Page 3 |
| 6 | Page 4 |
| 7 | Page 5 |
| 8 | Page 6 |
| 9 | Page 7 |
| 10 | Page 8 |
| 11 | Page 9 |
| 13 | Page 10 |
| 14 | Page 11 |
| 15 | Page 12 |
| 16 | Page 13 |
| 18 | Page 14 |
| 19 | Page 15 |
| 20 | Page 16 |
+---------+---------------+
and table user_privalges for user_id = 1 only.
+--------------------+---------+---------+
| user_privileges_id | user_id | page_id |
+--------------------+---------+---------+
| 1 | 1 | 2 |
| 2 | 1 | 3 |
| 3 | 1 | 5 |
| 4 | 1 | 6 |
| 5 | 1 | 7 |
| 6 | 1 | 8 |
| 7 | 1 | 9 |
| 8 | 1 | 10 |
| 9 | 1 | 11 |
| 10 | 1 | 13 |
| 11 | 1 | 14 |
| 12 | 1 | 15 |
| 13 | 1 | 16 |
| 14 | 1 | 18 |
| 15 | 1 | 19 |
| 16 | 1 | 20 |
+--------------------+---------+---------+
Select up.user_id, p.page_name FROM user_privileges up, pages p where p.page_id = up.page_id and up.user_id = 1 AND up.Assigned=1;
"What I want to get all the pages name and only those are marked that is assigned to that user." So with your edit you should try something like that with case statement
SELECT up.user_id, p.page_name,
CASE
WHEN up.page_id=p.page_id THEN '1'
ELSE '0'
END AS Assigned
FROM pages p left join user_privileges up
ON p.page_id = up.page_id
WHERE up.user_id = 1;
If you are only looking for the user_id = 1 you may do something as
select
1 as user_id,
p.page_name,
case when up.page_id is not null then 1 else 0 end as `Assigned`
from pages p
left join user_privalges up on up.page_id = p.page_id and up.user_id = 1
order by p.page_id

mysql code:
select *

inner tB
on tA.id = tB.tA_id
where tB.cat_id = 1
or tB.cat_id = 2
Group By tA_id
result from my mysql code:

+----+-------+--------+----------+
| 1 | 1 | 2 | Other |
| 3 | 2 | 2 | Other |
+----+-------+--------+----------+
How do I do?
Remove your group by tA_id because it is grouping cat_name Mobile and Other together.
If you need to keep it use ORDER BY tB.cat_id ASC which i believe will show the cat_id 1 and 2 like you need it
There is an error in query... JOIN is missing...
QUERY
SELECT *
FROM tA
INNER JOIN tB
ON tA.id = tB.tA_id
WHERE tB.cat_id = 1
OR tB.cat_id = 2
GROUP BY tA_id
This is fetching expected results

Try this :-
select *

inner join tB
on tA.id = tB.tA_id

group by tb.cat_name;
Hope it will help you.
Basically I need to create output TOP table where users are arranged by comparing their points with admin's points.
For example:
User3 | 0 //Everything was as admin had.
User5 | 3 //One song had 2 points different from admin and one was off by one
ect.
In my database I have three tables:
Table: rating
+------------+---------+----------+---------+
| rating_id | user_id | song_id | points |
+------------+---------+----------+---------+
| 1 | 1 | 4 | 0 |
| 2 | 1 | 3 | 1 |
| 3 | 3 | 2 | 3 |
| 4 | 4 | 2 | 2 |
| 5 | 2 | 1 | 4 |
Table: songs
+---------------+------------+
| song_name_id | song_name |
+---------------+------------+
| 1 | Song1 |
| 2 | Song2 |
| 3 | Song3 |
| 4 | Song4 |
| 5 | Song5 |
Table: users
+----------+----------+----------+
| id | username | password |
+----------+----------+----------+
| 1 | User1 | passw |
| 2 | User2 | wordp |
| 3 | User3 | somet |
| 4 | User4 | hings |
It should be something like this (not in any programming language):
Compare user_id > 1 with user_id=1 //Let's say that the comparable admin is user_id=1
$result= ABS(user.points-admin.points)++;
And put this to array as:
username => result
Then when I sort this array by result, I can print it as top table - who got the closest result to admin!
I tryed several different solutions but never got the right result.
Can anybody help me?
UPDATE:
Thanks!
With JOIN the result is:
+------------+---------+----------+---------+-----------+
| song_id |song_name| user_id |username |rating_diff|
+------------+---------+----------+---------+-----------+
| 1 | Song1 | 1 | admin | 0 |
| 2 | Song2 | 1 | admin | 0 |
...etc...
With LEFT JOIN the result is:
+------------+---------+----------+---------+-----------+
| song_id |song_name| user_id |username |rating_diff|
+------------+---------+----------+---------+-----------+
| 1 | Song1 | 11 | user2 | NULL |
| 1 | Song1 | 10 | user1 | NULL |
| 1 | Song1 | 12 | user3 | NULL |
| 1 | Song1 | 1 | admin | 0 |
| 2 | Song2 | 11 | user2 | NULL |
| 2 | Song2 | 10 | user1 | NULL |
| 2 | Song2 | 12 | user3 | NULL |
| 2 | Song2 | 1 | admin | 0 |
..etc..
So.. Something is wrong, the rating_diff does not work.
Assuming you want this comparison on a song-by-song basis (instead of a total or average across all songs), try:
select r.song_id,
s.song_name,
r.user_id,
u.username,
abs(r.points - r1.points) rating_diff
from rating r
join songs s on r.song_id = s.song_name_id
join users u on r.user_id = u.id
join rating r1 on r.song_id = r1.song_id and r1.user_id = 1
order by s.song_name, abs(r.points - r1.points)
This should sort the output by the song name, and then by the difference between the admin's points and the users' points. (Change the join on rating r1 to be a left join if you can't guarantee an admin rating for every song.)
