This is myquery in these query i have fetch the result from 4 tables using inner join.It return all the records which are matched from 4 tables.
But i want to also get that reords which are matched in fl_customer_profile table and fl_users table.And also get that records which ids are matched in 4 tables.
SELECT u.*,c.*,s.*,p.*
FROM fl_users u
INNER JOIN fl_customer_profile c
on u.id = c.userID
INNER JOIN fl_customer_subscription s
on u.id = s.userid
INNER JOIN fl_subscription p
on s.planId = p.id
fl_users Table
ID
| 879 |
| 884 |
fl_customer_profile Table
userID
| 879 |
| 884 |
I guess your are trying to get all the records that matches fl_customer_profile and fl_users whether they are present in other tables or not, Inner join will return records if they are present in both tables , while left join will return all records from left table and from second table will return only matched rows
SELECT u.*,c.*,s.*,p.*
FROM fl_users u
INNER JOIN fl_customer_profile c
on u.id = c.userID
LEFT JOIN fl_customer_subscription s
on u.id = s.userid
LEFT JOIN fl_subscription p
on s.planId = p.id

I have three tables to be join please see this three tables
composite_inventories
composite_has_inventories
inventories
above three table i have join using below query
SELECT u.id, u.purchase_item_name,u.sales_item_name, us.type ,Group_concat(s.itemcode) as Items FROM composite_inventories as u LEFT JOIN composite_has_inventories as us ON u.id = us.composite_inventory_id LEFT JOIN inventories as s ON US.inventory_id = s.id GROUP BY us.composite_inventory_id,us.type
I got output of my above query as below
but instead of above output i need output should be like this
id | Purchase_item_name | sales_item_name | purchase_items | sales_items
-------------+-------+-----------+----------------------------
12 | golden | NULL | A123,Z523,QQ5252 | NULL
13 | test | demoabc | Z523,QQ5252 | Z523
please help me to convert this query to laravel query.
To achieve what you want it's necessary to join to the inventories table twice, once for purchases and once for sales. Then you can do a GROUP_CONCAT on the items from each of those JOINed tables to get purchase_items and sales_items.
This query should give you the desired result (SQLFiddle)
SELECT u.id, u.purchase_item_name,u.sales_item_name, us.type,
GROUP_CONCAT(p.itemcode) AS purchase_items,
GROUP_CONCAT(s.itemcode) as sales_items
FROM composite_inventories as u
LEFT JOIN composite_has_inventories as us ON u.id = us.composite_inventory_id
LEFT JOIN inventories as s ON US.inventory_id = s.id AND us.type='sale'
LEFT JOIN inventories as p ON US.inventory_id = p.id AND us.type='purchase'
GROUP BY u.id
Output:
id purchase_item_name sales_item_name type purchase_items sales_items
12 golden (null) purchase Z523,QQ5252,A123 (null)
13 test demoabc purchase Z523,QQ5252 Z523
I have an table called product which lets say looks like this:
product
product_id | cults_id1 | cults_id2 | cults_id3
-----------------------------------------------------
1 | 5 | 4 | 2
And the also a table thats based on this called cultivar:
cultivar
cults_id | cults_name |
-------------------------
1 | berries |
2 | fruit |
3 | choc |
4 | wood |
5 | mysql! |
How would i create an JOIN query to get each name from cultivar table where the product id in product table is the same as cults_id in the cultivar table?
OUTPUT
My Product Cults :
berries, Mysql!, wood, fruit
Dont think an INNER JOIN is the way to go but i would have tried something like this:
$query = "SELECT cultivars.cults_name
FROM product
INNER JOIN wine_cultivar ON wine_cultivar.cults_id = product.cultivar_1_id
INNER JOIN wine_cultivar ON wine_cultivar.cults_id = product.cultivar_2_id
INNER JOIN wine_cultivar ON wine_cultivar.cults_id = product.cultivar_3_id
INNER JOIN wine_cultivar ON wine_cultivar.cults_id = product.cultivar_4_id
";
i tried a inner join multiple times targeting all the ids but dont think this is the way to go. Also this is just a part of my sql query.
Simply assign table aliases to each self join and then reference corresponding fields in SELECT.
Right now you join to same table but do not provide aliases to distinguish between the four which MySQL should have raised its Error #1066 for this attempt.
SELECT p.product_image_path, p.product_id, p.brand_name, p.product_name, b.botttle_size, v.vintage,
t.wine_type_blend, p.price, p.quantity, p.time_created, p.reference_number, p.shipping_cost,
c1.cultivar_type as cultivar_type1, c2.cultivar_type as cultivar_type2,
c3.cultivar_type as cultivar_type3, c4.cultivar_type as cultivar_type4
FROM product p
INNER JOIN wine_bottle b ON b.bottle_id = p.bottle_id
INNER JOIN wine_vintage v ON v.vintage_id = p.vintage_id
INNER JOIN wine_type t ON t.type_id = p.type_id
INNER JOIN wine_cultivar c1 ON c1.cultivar_id = p.cultivar_1_id
INNER JOIN wine_cultivar c2 ON c2.cultivar_id = p.cultivar_2_id
INNER JOIN wine_cultivar c3 ON c3.cultivar_id = p.cultivar_3_id
INNER JOIN wine_cultivar c4 ON c4.cultivar_id = p.cultivar_4_id
I've got repeating records with different 'manufacturer' fields. I'm trying to GROUP BY i.stocknumber but that only removes a record without collecting the other manufacturer result.
Some records have a NULL manufacturer field, and I've tried using GROUP_CONCAT in the subquery to elide the differing results for "manufacturer".
Here's my current query:
SELECT i.id,i.stocknumber,m.manufacturer
FROM inventory i
INNER JOIN makes mk on i.make = mk.id
INNER JOIN models md on i.model = md.id
INNER JOIN classes cl on i.class = cl.id
LEFT JOIN (
SELECT idm.id, idm.inventory_id, dm.manufacturer AS 'manufacturer'
FROM display_manufacturers dm
INNER JOIN inventory_display_manufacturers idm ON dm.id = idm.display_manufacturer_id
) m ON i.id = m.inventory_id
-- GROUP BY i.stocknumber
ORDER BY i.stocknumber
The result I get is:
Any thoughts on grouping the repeated records by concatenating the manufacturer field?
(NOTE: I already tried GROUP_CONCAT on the subquery)
DESIRED RESULT:
id | stocknumber | manufacturer
----------------------------------
946 | 011A | NULL
907 | 1001 | Sports Coach, Coachmen
1032 | 1001x | Sports Coach
etc....
Are you looking for this?
SELECT i.id, i.stocknumber, group_concat(distinct m.manufacturer) as manufacturers
. . .
GROUP BY i.stocknumber
EDIT:
This version explicitly uses your query as a subquery. It should not put all manufacturers on the same row:
select stocknumber, group_concat(distinct manufacturer) as manufacturers
from (SELECT i.id,i.stocknumber,m.manufacturer
FROM inventory i
INNER JOIN makes mk on i.make = mk.id
INNER JOIN models md on i.model = md.id
INNER JOIN classes cl on i.class = cl.id
LEFT JOIN (
SELECT idm.id, idm.inventory_id, dm.manufacturer AS 'manufacturer'
FROM display_manufacturers dm
INNER JOIN inventory_display_manufacturers idm ON dm.id = idm.display_manufacturer_id
) m ON i.id = m.inventory_id
) t
GROUP BY stocknumber ;
If what you are trying to do is removing the NULL fields, you just have to add a WHERE condition excluding the NULL fields
SELECT i.id,i.stocknumber,m.manufacturer
FROM inventory i
INNER JOIN makes mk on i.make = mk.id
INNER JOIN models md on i.model = md.id
INNER JOIN classes cl on i.class = cl.id
LEFT JOIN (
SELECT idm.id, idm.inventory_id, dm.manufacturer AS 'manufacturer'
FROM display_manufacturers dm
INNER JOIN inventory_display_manufacturers idm ON dm.id = idm.display_manufacturer_id
) m ON i.id = m.inventory_id
WHERE m.manufacturer IS NOT NULL
-- GROUP BY i.stocknumber
ORDER BY i.stocknumber
I am looking for single query where I can connect multiple tables.
The Query is as follows
`
SELECT
a.name as module_name,
a.id,
b.id as subject_id,
b.SUBJECT_name,
c.id as course_id,
c.course_name,
d.id as cordinator_id,
d.cordinator_name
FROM module_table a
LEFT JOIN subject_table b ON b.id = a.subject_id
LEFT JOIN course_table c ON c.id = a.course_id
LEFT JOIN cordinator_table d ON d.id = a.cordinator_ids
WHERE a.id = $somevalue
ORDER BY a.id DESC
`
Above query is producing error and when I am connecting the two tables Its showing all right
SELECT
a.name as module_name,
a.id,
b.id as subject_id,
b.SUBJECT_name
FROM module_table a
LEFT JOIN subject_table b ON b.id = a.subject_id
WHERE a.id = $somevalue
ORDER BY a.id DESC`
The first Table has all foreign keys for subject and course table, further subject table is connected to coordinator table with common id column.. I want the corresponding names of the id given in the module table..
The last table is the result of query I want from where I can collect my required data
My table structures are below
MODULE CAN BE INCLUDED ONLY IN A SUBJECT AND SUBJECT CAN BE INCLUDED IN COURSE
EACH SUBJECT CAN HAVE ANY NUMBER OF CORDINATORS WHICH I AM KEEPING THEM AS JSON value
-----------------------------------------------------------------------
MODULE TABLE
_____________________________________________________
id | subject_id | course_id | cordinator_id | name
-----------------------------------------------------------------------
COURSE TABLE
__________________
id | course_name
-----------------------------------------------------------------------
SUBJECT TABLE
_________________________________________________
id | course_id | cordinator_id | SUBJECT_name
-----------------------------------------------------------------------
CORDINATOR TABLE
______________________________________
id | cordinator_ids | cordinator_name
Result TABLE
___________________________________________________________________________________________
id | module_name | subject_id | subject_name | course_id | course_name | cordinator_ids
I am able to join two tables successfully with LEFT Join but on third it is reporting an error.
The problem is that you have a few typos and forgot to JOIN course_table.
Here is the right query:
SELECT
a.name as module_name,
a.id,
b.id as subject_id,
b.SUBJECT_name,
c.id as course_id,
c.course_name,
d.id as cordinator_id,
d.cordinator_name
FROM module_table a
LEFT JOIN subject_table b ON b.id = a.subject_id
LEFT JOIN course_table c ON c.id = a.course_id
LEFT JOIN cordinator_table d ON d.id = a.cordinator_id
WHERE a.id = $somevalue
ORDER BY a.id DESC
On this line:
b.SUBJECT_name,
you had to put uppercase "SUBJECT_name" as in your table subject_table schema.
And your query was lacking this JOIN to allow you to select course_table fields:
LEFT JOIN course_table c ON c.id = a.course_id
say i had the following tables
user_table
id username
1 abc
2 def
3 ghij
courses_table
id title
1 csc
2 math
3 syn
user_courses
user_id course_id
2 1
1 3
2 3
i want to select the username whos taking course 1 AND 3 ,
not at least 1 or 3 , i mean both 1 and 3
i've tried the following mysql queries
SELECT DISTINCT u.* FROM user_table as u LEFT JOIN user_courses as uc ON uc.user_id = u.id WHERE uc.course_id = 1 AND uc.course_id=3;
SELECT DISTINCT u.* FROM user_table as u LEFT JOIN user_courses as uc ON uc.user_id = u.id WHERE uc.course_id IN (1,3);
SELECT DISTINCT u.* FROM user_table as u LEFT JOIN user_courses as uc ON uc.user_id = u.id WHERE uc.course_id IN (1,3) AND uc.user_id = u.id ;
the first and third queries executed with no results shown , and the second one show all users who had at least course_id 1 or 3
if you are wondering why am i using the LEFT JOIN , this is because i need to join table's results , and the above line of code is just an example , and im using to get data from about 9 tables using the LEFT join .
any help please ? thanks
SELECT DISTINCT u.* FROM user_table as u LEFT JOIN user_courses as uc ON uc.user_id = u.id WHERE uc.course_id IN( 1,3) AND uc.user_id = 2 ";
this show me the result i want , its output "def" ,
but i can't use the user_id as a static value ( number 2 in this example )
This problem is called Relational Division
SELECT a.id, a.username
FROM user_table a
INNER JOIN user_courses b
ON a.id = b.user_ID
WHERE b.course_ID IN (1,3)
GROUP BY a.id, a.username
HAVING COUNT(*) = 2
SQL of Relational Division
If course_ID is not unique for every users considering that the user have retake the course, a DISTINCT keyword is needed to coung unique courses,
SELECT a.id, a.username
FROM user_table a
INNER JOIN user_courses b
ON a.id = b.user_ID
WHERE b.course_ID IN (1,3)
GROUP BY a.id, a.username
HAVING COUNT(DISTINCT b.course_ID) = 2
